2 SAFETY TRAINING INFORMATION  
The M/A-COM P7200 portable radio generates RF electromagnetic energy during  
transmit mode. This radio is designed for and classified as “Occupational Use  
Only,” meaning it must be used only during the course of employment by  
individuals aware of the hazards and the ways to minimize such hazards. This radio  
is NOT intended for use by the “General Population” in an uncontrolled  
environment.  
The P7200 portable radio has been tested and complies with the FCC RF exposure limits for  
“Occupational Use Only.” In addition, this M/A-COM radio complies with the following Standards and  
Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for  
exposure to humans:  
FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for  
Human Exposure to Radio Frequency Electromagnetic Fields.  
American National Standards Institute (C95.1 – 1992), IEEE Standard for Safety Levels with Respect  
to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.  
American National Standards Institute (C95.3 – 1992), IEEE Recommended Practice for the  
Measurement of Potentially Hazardous Electromagnetic Fields – RF and Microwave.  
2.1 RF EXPOSURE GUIDELINES  
To ensure that exposure to RF electromagnetic energy is within the FCC allowable  
limits for occupational use, always adhere to the following guidelines:  
CAUTION  
DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may  
also cause the FCC RF exposure limits to be exceeded. A proper antenna is the antenna supplied with  
this radio by M/A-COM or an antenna specifically authorized by M/A-COM for use with this radio.  
(Refer to Table 6-1.)  
DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). Transmitting more  
than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio  
is transmitting when the “TX” indicator appears in the display. The radio will transmit by pressing the  
“PTT” (Push-To-Talk) button.  
Always transmit using low power when possible. In addition to conserving battery charge, low power  
can reduce RF exposure.  
ALWAYS use M/A-COM authorized accessories (antennas, batteries, belt clips, speaker/mics, etc).  
Use of unauthorized accessories may cause the FCC Occupational/Controlled Exposure RF  
compliance requirements to be exceeded. (Refer to Table 6-1.)  
As noted in Table 2-1, ALWAYS keep the device and its antenna AT LEAST 1.1 cm (0.43 inches)  
from the body and at least 2.5 cm (1.00 inch) from the face when transmitting to ensure FCC RF  
exposure compliance requirements are not exceeded. However, to provide the best sound quality to

2.2 ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY  
During transmissions, this M/A-COM radio generates RF energy that can possibly cause interference with  
other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to  
do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as  
hospitals, aircraft, and blasting sites.

3 OPERATING TIPS  
Antenna location and condition are important when operating a portable radio. Operating the radio in low  
lying areas or terrain, under power lines or bridges, inside of a vehicle or in a metal framed building can  
severely reduce the range of the unit. Mountains can also reduce the range of the unit.  
In areas where transmission or reception is poor, some improvement may be obtained by ensuring that the  
antenna is vertical. Moving a few yards in another direction or moving to a higher elevation may also  
improve communications. Vehicular operation can be aided with the use of an externally mounted  
antenna.  
Battery condition is another important factor in the trouble free operation of a portable radio. Always  
properly charge the batteries.  
3.1 EFFICIENT RADIO OPERATION  
For optimum audio clarity at the receiving radio(s), hold the portable radio approximately two inches  
from your mouth and speak into the microphone at a normal voice level.  
Keep the antenna in a vertical position when receiving or transmitting a message.  
Do not hold the antenna when receiving a message and, especially, do not hold when transmitting a  
message.  
Do NOT hold onto the antenna when the radio is powered on!  
3.1.1  
Antenna Care and Replacement  
Do not use the portable radio with a damaged or missing antenna. A minor burn  
may result if a damaged antenna comes into contact with the skin. Replace a  
damaged antenna immediately. Operating a portable radio with the antenna missing  
could cause personal injury, damage the radio, and may violate FCC regulations.  
Use only the supplied or approved antenna. Unauthorized antennas, modifications or  
attachments could cause damage to the radio unit and may violate FCC regulations.  
(Refer to Table 6-1.)  
3.1.2  
Electronic Devices  
RF energy from portable radios may affect some electronic equipment. Most modern  
electronic equipment in cars, hospitals, homes, etc. is shielded from RF energy. However,  
in areas in which you are instructed to turn off two-way radio equipment, always observe  
the rules. If in doubt, turn it off!  
CAUTION  
13

MM23772, Rev. B  
3.1.3  
Aircraft  
Always turn off a portable radio before boarding any aircraft!  
Use it on the ground only with crew permission.  
DO NOT use while in-flight!!  
3.1.4  
Electric Blasting Caps  
To prevent accidental detonation of electric blasting caps, DO NOT use two-way  
radios within 1000 feet of blasting operations. Always obey the "Turn Off Two-Way  
Radios" signs posted where electric blasting caps are being used. (OSHA Standard:  
1926.900)  
3.1.5  
Potentially Explosive Atmospheres  
Areas with potentially explosive atmospheres are often, but not always, clearly  
marked. These may be fuelling areas, such as gas stations, fuel or chemical transfer or  
storage facilities, and areas where the air contains chemicals or particles, such as  
grain, dust, or metal powders.  
Sparks in such areas could cause an explosion or fire resulting in bodily injury or even  
death.  
Turn OFF two-way radios when in any area with a potentially explosive atmosphere.  
It is rare, but not impossible that a radio or its accessories could generate sparks.

4 BATTERIES  
The P7200 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd) or Nickel Metal  
Hydride (NiMH) batteries. Please follow the directions below to maximize the useful life of each type of  
battery.  
If the battery is ruptured or is leaking electrolyte that results in skin or eye contact  
with the electrolyte, immediately flush the affected area with water. If the battery  
electrolyte gets in the eyes, flush with water for 15 minutes and consult a physician  
immediately.  
4.1 CONDITIONING BATTERY PACKS  
4.1.1  
Conditioning NiMH battery packs  
Condition a new NiMH battery before putting into use. This also applies to rechargeable NiMH batteries  
that have been stored for long periods (weeks, months, or longer). Conditioning requires fully charging  
and fully discharging the battery three (3) times using a “battery analyzer/conditioner/charger.” M/A-  
COM recommends either the Cadex® C7400 or the Intelligent Technologies Co. BC3506QP-5 iTECH®  
iQfive® battery conditioners, purchased directly from M/A-COM. These units condition a battery pack by  
automatically charging and discharging (cycling) the battery.  
Failure to properly condition NiMH battery packs before initial use will result in  
shortened performance by the battery.  
CAUTION  
4.1.2  
Conditioning NiCD Battery Packs  
A new NiCD battery does not require conditioning before use. Periodically condition NiCD batteries to  
avoid the memory effect. If a NiCD battery is repeatedly charged and not fully discharged, the result is  
lower voltage and lower capacity. Fortunately, both voltage and capacity are restored through battery  
conditioning.  
Always use M/A-COM authorized chargers and conditioners. Use of unauthorized  
chargers and conditioners may void the warranty.  
CAUTION  
4.1.3  
Additional Information  
For more information regarding the proper care of portable radio batteries or establishing a battery  
maintenance program, refer to ECR-7367 which may be ordered by calling toll free 1-800-368-3277, then  
select option 7.

MM23772, Rev. B  
4.2 CHARGING BATTERY PACKS  
Battery chargers are available from M/A-COM with nominal charge times of one hour. Combinations  
include single and multi-position, rapid charge units.  
M/A-COM chargers are rapid chargers specifically designed for charging nickel-based battery packs. The  
chargers differentiate between NiCd or NiMH battery packs and automatically adjust charging rates.  
Refer to the appropriate charger manual for specific operating instructions.  
4.2.1  
Charging Guidelines  
Observe the following guidelines when charging a battery pack:  
Avoid high temperature during charging.  
Discontinue use if the charger is overheating.  
Only charge NiCd or NiMH battery packs using a rapid charger approved for use by M/A-COM.  
Do not leave batteries in the charger indefinitely. For best results leave the battery in the charger for  
two to six hours after the Green Ready LED comes on. Then place the battery pack into service and  
fully discharge (as indicated by the radio low battery warning) before re-charging.  
If any faults are encountered while charging the battery pack, consult the charger’s manual to determine  
the cause and possible corrective action.  
4.3 BATTERY PACK USAGE  
NiCd and NiMH batteries vary in capacity and life cycle. NiCd batteries have a longer life cycle than  
NiMH batteries whereas NiMH batteries have a larger capacity. Both types of batteries require following  
basic usage guidelines in order to increase the battery runtime or shift life.  
4.3.1  
Usage Guidelines  
The following guidelines will help increase the battery runtime or shift life:  
Ensure the battery pack is fully discharged (as indicated by the radio low battery warning) before re-  
charging.  
Periodically condition battery packs, frequency to be determined based on usage patterns (refer to  
ECR-7367). If the battery is fully discharged (to radio Low Battery warning) during routine use, the  
frequency of conditioning may be extended.  
Do not leave NiCd or NiMH batteries in a charger for more than a few days.

5 INTRODUCTION  
The P7200 series radios are dual-band multi-mode portable radios. The P7200 series radio is available  
without a front mounted keypad (P7230 Select model - Figure 5-1), with a 6-buttoned front mounted  
keypad (P7250 Scan model - Figure 5-2) and with a DTMF front mounted keypad (P7270 System model -  
Figure 5-3). The dual-band (700/800 MHz) P7200 portable radio delivers end-to-end encrypted digital  
voice and IP data communications. It is designed to support multiple operating modes including:  
OpenSky® Trunked mode (OTP)  
EDACS® or ProVoiceTrunked mode  
P25 Trunked mode  
P25 Digital Conventional mode  
Conventional Analog mode  
The P7200 portables can include all of these modes or just one. Additional modes of operation can be  
added with software updates.  
The P7200 supports a full range of advanced digital trunking features, including voice group calls,  
priority scanning, emergency calls, late call entry, and dynamic reconfiguration. It performs autonomous  
roaming for wide area applications. High quality voice coding and robust audio components assure  
speech clarity.  
In the trunked modes, the user selects a communications “operating” system (i.e., OpenSky, EDACS,  
ProVoice, or P25) and group. While communicating in a trunked mode, channel selection is transparent to  
the user and is controlled via digital communication with the system controller (e.g. base station in an  
OpenSky system or a CSD in an EDACS system). This provides advanced programmable features and  
fast access to communication channels.  
In Conventional Analog mode, the user selects a channel and communicates directly on that channel. In  
this mode, a system refers to a set of channels. A channel is a transmit/receive radio frequency pair.  
The exact operation of the radio will depend on the operating mode, the radio’s programming, and the  
particular radio system. Most features described in this manual can be enabled through programming.  
Consult your System Administrator for the particular features programmed into your P7200.  
For further detail about features and operation refer to the appropriate maintenance manual or contact  
your System Administrator.

7.5 TRI-COLOR LED  
Figure 7-3: Tri-Color LED  
The Tri-Color LED changes color to indicate radio status and is visible from both the front and top of the  
radio (see Figure 7-3). In OpenSky mode only two radio states are reflected by the LED and the status  
they represent are:  
Green:  
Red:  
Receiving  
Transmitting  
Orange:  
If the LED is flashing rapidly, the radio is receiving an emergency call. If the LED is  
flashing every ½ second, the selected talk group is in the emergency state (although not  
transmitting). If the selected talk group is in the emergency state, an asterisk will be  
displayed next to the talk group name.  
7.6 LOG IN TO THE NETWORK  
Login occurs either automatically (auto registration) if the radio has a valid registration or, if enabled and  
authorized for encryption (Section 7.27), requires the user to enter a User ID and password.  
If encryption is enabled and authorized on the radio, the user will be prompted to “Pls Login” with the *1  
login command, a User ID, and password.  
1. Press *1 (Login command).  
2. Enter the full 10-digit User ID.  
3. Press the # key.  
4. Enter the password.  
If the radio is configured for alpha-numeric passwords and the password has consecutive  
duplicate numbers (“MES33” for example), enter # between the consecutive duplicate numbers  
so the radio will not interpret the entry as a letter (“D” in this example).  
If the radio is configured for numeric-only passwords, do not enter # between duplicated  
numbers.  
5. Press the # key twice.  
The User ID may be remembered from the previous log-in. (Refer to Section 7.7 for further details  
regarding log-off commands.) The password will be established before the radio is put into operation.  
Contact the local OpenSky network administrator for more information.  
If necessary, contact radio system administration personnel for log-in assistance and/or  
radio-specific log-in instructions.

MM23772, Rev. B  
7.7 LOG OFF THE NETWORK  
The *0## command de-registers the radio. Typically, this is automatically performed when powering  
down the radio. Using this method, the User ID is remembered by the radio so only the password is  
needed at next log-in. Manually log-off by pressing *0##.  
If a user is logged in using encryption features, it is necessary to log-off when encryption is no longer  
required.  
7.8 PERSONALITY  
As illustrated in Figure 7-4, a personality defines the profiles and talk groups available to the user. It is  
the structuring of a collection of profiles and privileges established by the OpenSky network administrator  
to provide the user with a comprehensive set of profiles to communicate effectively with the necessary  
talk groups or individuals.  
Personalities are stored on the network and downloaded over-the-air to the radio. This process is called  
“provisioning.” Provisioning occurs at radio power-up (if the personality is not already stored in the  
radio’s memory) and at user log-in. When changes are made to the personality, the radio is automatically  
re-provisioned. Each personality can contain up to sixteen (16) profiles and each profile can contain up to  
sixteen talk groups.  
7.8.1  
Profiles  
As stated above, each profile can contain up to sixteen (16) talk groups. A profile also defines the radio’s  
emergency behavior. All transmissions are made on the selected talk group (displayed on the top line of  
the dwell display). The user can change the selected talk group to any of the other talk groups within the  
profile.

Talk Groups  
A talk group represents a set of users that regularly need to communicate with one another. There can be  
any number of authorized users assigned to a talk group. Talk groups are established and organized by the  
OpenSky network administrator. An OpenSky talk group is similar to a channel within a conventional FM  
radio system.

7.16 STEALTH MODE  
For some users, it is important to be able to turn off the radio’s display lights and side tones, but not the  
radio traffic. For example, in covert operations, lights and sounds could inadvertently expose an otherwise  
unobservable radio user. For this purpose, the radio has a Stealth feature that disables the radio display  
light, indicator light and audible side tones.  
When stealth mode is on, the radio continues to scan the programmed list of talk groups and the user can  
key-up on the selected talk group.  
7.16.1 Enabling Stealth Mode  
Press the or buttons to scroll through menus until “StealthMenu” appears in the display. To  
immediately activate Stealth Mode press the or button once. This activates Stealth Mode, exits the  
Stealth Menu, and returns to the Dwell Display.  
The display lights, indicator lights, and side tones are disabled. The stealth mode icon is displayed.  
7.16.2 Disabling Stealth Mode  
To re-enable all lighting, side tones and exit Stealth Mode, press any key other than PTT or Emergency.  
This returns to the Dwell Display.  
The display lights, indicator lights, and side tones are re-enabled. The stealth mode icon disappears.  
With stealth mode on, pressing any radio button (other than the mic’s PTT button  
or the emergency button) on front panel will immediately turn stealth mode off. For  
example, pressing the button on the front panel will turn stealth mode off.  
7.17 ADJUSTING SIDE TONE AUDIO LEVEL  
The radio sounds confirming tones called “side tones” when its buttons are pressed. Most users find this  
audible confirmation helpful when navigating the menus. Side tone audio level can be adjusted or turned  
completely off using the “Side Menu.”  
For covert operations, it may be necessary to turn off side tones. For safety’s sake, turning off the radio  
during covert operations is not recommended.  
If the radio is operating properly but side tones are not heard when the menu buttons are pressed, the side  
tones are probably turned off. To turn them back on, access the “Side Tone” menu and select a setting  
other than “off.”  
Use the following procedure set side tone level:  
1. Press the or buttons to cycle through the menu until “Side Menu” is displayed.  
2. Press or to change to the desired level (Off, Low, Medium, and High). To turn side tones  
completely off, use the “Off” setting.

MM23772, Rev. B  
7.18 CHANGE OPERATING MODE  
1. Press the or buttons to cycle through the menu until “Mode Menu” is displayed.  
2. Press or to select the desired operating mode.  
3. Press and use or to select Y or N.  
4. Press again to make selection and return to the dwell display  
7.19 RECEIVING AND TRANSMITTING VOICE CALLS  
As soon as the radio completes the initialization sequence and registers on the OpenSky network, the user  
will begin to hear calls from the talk groups in the active profile, if available.  
7.19.1 Receiving a Voice Call  
No action is required on the part of the user.  
The caller’s alias is only shown when the selected talk group matches the received talk group. Otherwise,  
the name of the received talk group is displayed.  
7.19.2 Transmitting a Voice Call  
1. Select the desired talk group.  
2. Depress and hold the PTT button, wait a couple of seconds. If programmed by the administrator, a  
grant tone will be sounded.  
3. Begin speaking into the microphone in a normal voice.  
4. For maximum clarity, hold the radio approximately 2 inches from your mouth. Take care not to cover  
up the microphone while speaking.  
5. Release the PTT button to terminate an outgoing voice call.  
7.20 ADJUSTING AUDIO TREBLE LEVEL  
The tone of received signals can be adjusted using the radio’s “Treble Menu.”  
1. Press the or buttons to cycle through the menu until “Treble Menu” is displayed.  
2. Press or to increase or decrease level. There are four levels available: low, medium, medium-  
high, and high.  
3. Press or wait a few seconds to return to the dwell display.  
7.21 TALK GROUP LOCK OUT  
There are two ways to focus voice communications by suppressing calls from talk groups in the active  
profile.  
No Scan. By changing the Scanning Mode to “No Scan” only the selected talk group is scanned.  
Lock Out. By locking out selected talk groups, background noise or chatter can be eliminated and  
scanning resources can be focused on just those groups whose calls you wish to monitor.  
36  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
MM23772, Rev. B  
Lock out is a listening (receive) function and only blocks received calls on locked out talk  
groups. Lock out does not affect transmit capability. “No Scan” and “Lock Out” do not  
apply to recent emergency lock outs.  
Only talk groups in the active profile can be locked out, since they are the only talk groups whose voice  
calls can be heard on the radio. Talk group lock out is a scan-related feature. With lock out, one or more  
talk groups in the active profile can be temporarily disabled from being scanned. Calls are not received on  
locked-out talk groups. Lock out settings are not retained between profile changes or when the radio is  
power cycled.  
If the Scan Mode is “Fixed,” P1 and P2 groups CANNOT be locked out. See Section 7.22  
for more information.  
The default emergency and emergency-capable talk groups can be locked out if they are NOT in an  
emergency state. If a talk group is locked out and is subsequently changed to the currently selected talk  
group, it will automatically be unlocked by the radio so the user can hear calls on the talk group. The  
radio may be configured so all talk groups are automatically locked out by default. In this case, they must  
be manually unlocked, if desired.  
7.21.1 Lock Out a Talk Group  
1. Use the or buttons to scroll through the menu choices until “LockOutMenu” appears in the  
display.  
2. Use the or keys to scroll through the list of talk groups, if any, until the user group you want to  
lock out appears in the display.  
3. Press the key to select the lockable talk group.  
4. “<” appears next to the locked out talk group.  
7.21.2 Unlock a Talk Group  
1. Use the or buttons to scroll through the menu choices until “LockOutMenu” appears in the  
display.  
2. Use the or keys to scroll through the list of talk groups, if any, until the user group you want to  
unlock appears in the display.  
3. Use the key to unlock the displayed talk group.  
Changing the active profile removes any lockouts you have made.  
Turning off the radio removes any lockouts you have made.

7.22 SCANNING  
7.22.1 Selecting Scan Modes  
Three scanning modes are available for the radio, but only one can be active at any time. Changing the  
scanning mode changes the way the radio scans voice calls for all of the profiles in the radio personality,  
no matter which profile is or becomes active.  
The choice of scanning mode broadens or narrows the span of communications with all the groups in  
profiles you listen to, but does not affect your interaction with those groups you talk with.  
The scanning modes available for selection may be limited to a subset of the three scanning modes by the  
administrator.  
Table 7-6: Scan Modes  
SCAN  
EXPLANATION  
MODE  
Eliminates distractions.  
Full communications (listen and talk) with the active talk group.  
No calls received from other talk groups.

Normal  
Allows dragging of the selected talk group, P1, P2, and default emergency talk groups to the  
site on which the radio is registered. (If other calls are available at the site, they also can be  
heard but they will not be actively dragged.)  
The default emergency talk group, as well as any emergency-enabled talk groups, is only  
dragged if it is in emergency mode.  
The priority groups are fixed to the selected profile’s pre-defined P1 and P2 groups  
(configured via the UAS). In this mode, P1 and P2 groups CANNOT be locked out.  
The user can scan all talk groups in the active profile that are not locked out, as long as there  
is demand on the site.  
Fixed  
Allows dragging of the P1, P2, and selected talk group to the site on which the radio is  
registered. If other calls are available at the site, they can also be heard, but they will not be  
actively dragged.  
The default emergency talk group, as well as any emergency-enabled talk groups, is only  
dragged if in emergency mode.  
The scanning mode choice remains in effect until it is changed. Even if the radio is turned off, the current  
scanning mode selection is saved for the next use.

Emergency capable group in emergency state  
Priority 1 talk group.  
Priority 2 talk group.  
Other (non-priority).  
7.22.3.1 Changing Scan Priority  
1. Press the or keys until “Priority1” or “Priority2” appears in the display (Priority1 group has  
higher priority than the Priorty2 group).  
2. Press the or button until the desired talk group is displayed.  
3. Press the key to select and activate the selection. The radio automatically returns to the Dwell  
Display.  
Changing the priority of a listen group does not change your talk group.  
You set priority for two talk groups, but only in the selected profile.  
The scanning priority settings are reset to the default values when the radio is turned  
off.  
7.23 MAKING SELECTIVE CALLS  
Selective calling is the capability for two voice radio units to obtain and use an independent talk path for a  
private call. A properly equipped radio can initiate a selective call to any radio in the system that is also  
programmed for selective calls.  
39  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
MM23772, Rev. B  
In the OpenSky system, a radio can be configured to initiate selective calls through a pre-programmed list  
in memory called a speed dial list. Alternatively, a properly equipped radio can initiate a selective call to  
any radio in the system by entering the ten-digit User ID (similar to a telephone number) of the target  
radio. Some radios are configured to only receive (not initiate) selective calls.  
Selective calls are terminated if an emergency is declared. The network limits selective  
calls to ten (10) minutes maximum.  
If a Selective Call is attempted without registration, “No Priv” is displayed.  
7.23.1 Manually Dialing a Selective Call (P7270 Only)  
1. Enter *8, the User ID number of the user being called, and the # key (no dashes or spaces). (This  
feature must be enabled by the administrator.)  
*8<destination user id>#  
A shortened User ID number can be dialed using the following guidelines:  
If the radio being called is in the same region and agency – enter only the last four digits.  
If the radio being called is in the same region, but a different agency – enter the last seven digits.  
If the radio being called is in another region or if the area is unknown – enter all ten digits.  
2. Press PTT (and release) to ring the other user.  
The ring tone is sounded.  
If the other user accepts the call, the called user’s alias will appear in initiating caller’s display. The  
two are now in a private call until one ends the call, the call is terminated due to an initiated  
emergency, or the maximum time limit of ten (10) minutes is reached.  
If the called radio is busy, “BUSY” will appear in the second line of the display.  
7.23.2 Selective Call Using Speed Dial  
Speed dial numbers are defined and provisioned by the OpenSky network administrator  
and cannot be manually entered into the radio by the user. Contact the administrator if  
changes to the speed dial list are required.  
1. Scroll through the Menu options using the or button until “Speed Dial” appears in the second  
line of the display. Using the or keys, scroll through the pre-programmed speed-dial numbers  
until the desired number appears in the display and press the PTT button.  
OR  
2. Press and hold a key associated with a given number for more than three seconds. For example, press  
and hold the to open the Speed Dial Menu and display the third number in the speed dial list.  
Press the PTT button.  
A ring tone is sounded.

MM23772, Rev. B  
If the other user accepts the call, the called user’s alias will appear in initiating caller’s display. The two  
are now in a private call until one ends the call, or the call is terminated due to an initiated emergency.  
If the called radio is involved in another selective call, “BUSY” will appear on the second line of the  
display. “Unavailable” is displayed when the call has not been answered after a 1 minute timeout or when  
the other party is not registered on the network.  
7.23.3 Accepting a Selective Call  
1. The radio will ring (like a telephone), indicating you are receiving a Selective Call.  
2. Press the to accept the incoming selective call.  
3. “CONNECT” will appear in the display, followed by “Lim 10 Min.” “SEL CALL” and the alias of  
the caller appear in the display once the call is established.  
7.23.4 Rejecting a Selective Call  
When a Selective Call is being received (the radio is ringing), you can reject the call by pressing either of  
the or buttons, the button, or by turning the Voice Group Selector Control knob. The call will  
be rejected and “Reject” appears on the callers display.  
7.23.5 Terminating a Selective Call  
Terminate a Selective Call (call must be active) by pressing the , , , , #, or buttons, or by  
turning the Voice Group Selector Control knob. “HANGUP” will appear in the display followed by the  
active talk group.  
7.24 SELECTIVE ALERTS  
Selective alert messaging is an OTP feature that allows one of up to eight (8) pre-programmed (canned)  
text messages to be sent from one radio to another. The sender specifies a destination (receiving) radio,  
selects one of the pre-programmed text messages, and then transmits it to the destination radio. The  
message delivery system adds sender and time-of-day information and forwards the message to the  
destination (receiving) radio. The sending radio receives a brief message noting the status of the  
transmission.  
Received messages are stored in the radio until deleted or until the radio is rebooted. Received messages  
do not survive a reboot.  
7.24.1 Defining Messages  
All selective alert messages are pre-defined. The messages are programmed and provisioned remotely by  
your OpenSky system administrator. The radio user cannot create selective alert message content. The  
entire selective alert message, including the abbreviation, can be up to 200 characters long.  
When sending a selective alert message, the radio may display one of the following status messages

7.26 EMERGENCY COMMUNICATIONS  
The P7200 portable radio is capable of sending an emergency alert and making emergency calls on the  
network. The OpenSky system handles emergency calls with the highest priority, allowing you or the  
people you serve to get needed help.  
Emergency call and alert capability for a profile is configured by the system administrator.  
The radio that initiates an emergency alert emits a signal of 3 distinct beeps that only goes  
to the dispatch console.

is changed, (assuming there is an emergency on one of the talk  
groups for the new profile).  
If the orange LED is flashing rapidly, the radio is receiving an  
emergency call. If the LED is flashing every ½ second, the  
selected talk group is in the emergency state (although not  
transmitting). If the selected talk group is in the emergency state,  
an asterisk displays next to the talk group name.  
No emergency audio (voice)  
transmission (hot-mic) capability  
available (per programming by  
system administrator)  
In addition to the Emergency Alert signal, the microphone goes  
hot for a predetermined length of time to allow for emergency  
audio (voice) transmission. The radio declaring the emergency has  
channel access priority. Note that the User can also use the PTT  
after the pre-determined hot-mic audio transmission, or during to  
extend the initial hot-mic audio transmission.  
7.26.1 Declaring an Emergency Call or Alert  
1. Press the red emergency button on the radio to enter emergency mode.  
The emergency behavior for the selected profile is configured by the network  
administrator. This determines whether pressing the Emergency button sends an  
Emergency Call or just an Emergency Alert. An Emergency Alert is always part of and  
sent with an Emergency Call.  
If the active profile of the unit initiating the emergency is configured to Emergency Alert, the three-  
beep emergency alert signal is sent only to the dispatcher console.  
If the active profile of the unit initiating the emergency is configured to Emergency Call, the three-  
beep emergency alert signal is sent to the dispatcher console and to all other radios within the selected  
talk group. The default emergency talk group becomes the selected talk group. The display will  
alternate between the emergency talk group name and “EMERGENCY” to indicate that the  
emergency has been initiated.  
2. The microphone is hot (open mic) for a programmed amount of time in order to send your voice out  
on the emergency talk group.  
All of the radios in the emergency talk group hear your call and see the emergency talk group displayed  
on their radio.  
7.26.2 Receiving an Emergency Call  
Initially, when receiving an emergency call, the radio sounds the emergency tone (three short high-  
pitched tones).  
The radio will flash “EMERGENCY” and display the alias of the user that triggered the emergency or the  
alias of the talk group (if the incoming talk group is the selected talk group of the receiving radio).

MM23772, Rev. B  
With “No Scan,” only the emergency tone is heard, not the initial open mic transmission.  
To dismiss or ignore the emergency, refer to Section 7.26.3.  
7.26.3 Dismissing an Emergency  
The “Dismissing an Emergency” function allows you to “ignore” an emergency declared by another user.  
An emergency is dismissed for a configurable amount of time (default = 5 minutes).  
1. After receiving an emergency call, press the or button until you see “EmgDismiss.”  
2. Press the to toggle “<” on (dismiss) and off. This works in similar fashion to the lock out menu.  
The emergency dismiss timer is cleared when the emergency is cleared.  
7.26.4 Clearing an Emergency Call or Alert  
1. When the emergency ends, press and hold the red emergency button for three to five seconds to clear  
the emergency alert and call while on the active emergency talk group. The remove tone sounds when  
the emergency is cancelled.  
2. The radio returns to your default selected talk group. The “EMERGENCY” display is removed from  
the main screen.  
An Emergency Alert can only be cleared by the dispatcher or the initiator.  
An Emergency Call can be cleared by the dispatcher, the initiator, or someone whose radio  
has supervisory privileges.  
7.27 OPENSKY ENCRYPTION  
In the OpenSky network, both data and voice use a 128-bit or 256-bit key encryption standard published  
by the Federal Information Processing Service (FIPS), called Advanced Encryption Standard (AES). AES  
is approved by the U.S. Department of Commerce for encryption of classified materials.  
When encryption is enabled on the network, data is encrypted from the MDIS to the Mobile End System  
(MES) (e.g., P7200 portable radio). This form of encryption provides airlink security.  
Voice encryption is handled either automatically or manually. Automatic encryption is initiated through  
the Unified Administration Server (UAS) for a specific talk group and requires nothing from the user.  
Manual encryption is initiated by two or more radio users. Both methods of encryption are discussed in  
the following sections.  
When a user transmits encrypted voice, any listening users with different encryption keys  
hear distorted voice and “No Access” appears in the radio display.  
45

MM23772, Rev. B  
7.27.1 Automatic Encryption  
For automatic encryption, a system administrator will select the talk group to be encrypted at the interface  
to the UAS. Once the talk groups have been selected and identified as secure, credentials for key  
generation are generated automatically by the system and provisioned to authorized users. This process  
requires that authorized users login to the network and be authenticated. Encryption keys require no  
manual handling and are never sent “in the clear” over any network interface or airlink.  
7.27.1.1 Using Automatic Encryption  
1. Locate the talk group that has been encrypted at the system administrator level.  
2. “Pls Login” appears in the display (unless the keypad was used to log in).  
3. Login normally by entering your User ID and Password.  
If a user is engaged in a call on a talk group encrypted at the system administrator level, “SECURE” will  
appear in the display if the user is logged into that talk group.  
If a secure call is in progress elsewhere and the user has not logged in, the main display will alternate  
between no access “NO ACC” and the alias of the radio that is currently engaged in the secure call. The  
alias only shows if the active talk group matches the received talk group, otherwise only the talk group  
name is displayed.  
7.27.2 Manual Encryption (P7270 Only)  
Two or more users can manually encrypt a call, if enabled, without an established encrypted talk group. A  
pre-determined “key or code” is required. Note that while a user is engaged in an encrypted call, users  
within the talk group that are not encrypted can still make standard voice calls on that talk group. The  
encrypted user can hear the standard unencrypted calls, but cannot respond while still manually  
encrypted.  
Manual key entry only affects the currently selected talk group. All available talk groups within the  
current profile may be independently encrypted. Encryption keys are lost if the profile is changed.  
The key must be pre-determined by the users prior to making a manually encrypted call on  
a talk group and is entered into the radio using the keypad. For 128 bit encryption, this key  
is between 1 and 16 digits. For 256 bit encryption, this key is between 17 and 32 digits.  
7.27.2.1 Using Manual Encryption  
1. Press *32 on the keypad.  
2. Enter the key (1 – 16 digits for 128 bit encryption; 17 – 32 digits for 256 bit encryption).  
3. Press #.  
4. To end manual encryption, press *33.  
If a user is engaged in a call on a talk group that has been manually encrypted at the radio level, “Secure”  
will appear in the display.  
If a secure (encrypted) call is in progress, and the user has not entered the key, the display will alternate  
between no access “No Access” and the alias of the radio that is currently engaged in the secure call.  
Once the user has terminated manual encryption “Unsecure” will appear in the display for a brief interval.

7.28 DYNAMIC REGROUPING  
Dynamic regrouping requires that the network administrator determine which radio users should be  
formed into an impromptu talk group to respond to particular emergency conditions.  
The administrator will edit the personalities of the affected radios to include an emergency profile and  
then page the affected radios to re-register with the network to receive their edited personalities.  
In response, affected radios automatically re-register to receive their edited personalities. During re-  
registration, subscriber equipment will default to the emergency profile selected by the administrator.  
7.29 GPS COORDINATES  
The radio’s current latitude and longitude coordinates may be displayed using the “GPS” menu. The  
following procedure assumes a GPS antenna is connected to the radio and it is receiving adequate signals  
from GPS satellites:  
1. Press or until the “GPS” menu appears in the display. Current GPS coordinate latitude and  
longitude data continuously scrolls in the top line of the display in a degrees:minutes:seconds format.  
2. Press or to change to another menu.  
If the internal GPS receiver’s data is expired (30 minutes or more) or unavailable, the radio  
uses the serving base station’s coordinates [GPS (Site) is displayed]. The GPS Menu will  
also indicate if the data is aged (2 minutes or more) [GPS (Aged) is displayed]

8 EDACS OPERATION  
8.1 TURNING ON THE RADIO  
1. Power ON the radio by rotating the POWER ON-OFF/VOLUME knob clockwise. A short alert  
signal (if enabled through programming) indicates the radio is ready to use. Refer to Figure 8-1 for  
location of the POWER ON-OFF/VOLUME KNOB.  
2. The display shows the last selected system and group or a default system and group (depending on  
programming).  
3. Adjust the POWER ON-OFF/VOLUME knob to the desired volume level.  
4. Select the desired system and group. The display indicates the current system and group names.  
5. The radio is now ready to transmit and receive calls.  
In the trunked environment, CC SCAN will be displayed if communication with the  
system's control channel cannot be established. This may occur if, for example, the  
radio is out of range of the trunking site. It may be necessary to move to another  
location or select another trunking system to re-establish the control channel link for  
trunked mode operations. CC SCAN is displayed on the group line until a control  
channel is accessed.  
8.2 CONTROLS  
The radio features two rotary control knobs and an emergency button mounted on the top of the radio  
(Figure 8-1). Push-To-Talk and option buttons are mounted on the side (Figure 8-1). The front mounted  
keypad has no buttons on the P7230 Select model, six buttons on the P7250 Scan model, and 15 buttons  
on the P7270 System Radio.

8.2.1  
Buttons and Knobs  
This section describes the primary function of the button and knob controls. Other functions associated  
with these controls are detailed in later sections.  
POWER ON-OFF Applies power to and adjusts the receiver’s volume. Rotating the control clockwise  
VOLUME KNOB applies power to the radio. A single alert tone (if enabled through programming)  
indicates the radio is operational.  
Rotating the control clockwise increases the volume level. Minimum volume levels  
may be programmed into the radio to prevent missed calls due to a low volume  
setting. While adjusting the volume the display will momentarily indicate the  
volume level (i.e. VOL=31). The volume range is from a minimum programmed  
level of zero (displayed as OFF in the display) up to 31, which is the loudest level.  
CONTROL KNOB Selects systems or group/channels (depending on programming). This is a 16-  
position rotary knob.  
Note: A mechanical stop, which can limit the positions accessed, is shipped with  
the radio but must be installed. To install the mechanical stop, remove the channel  
knob, loosen the set screw on the channel knob metal base (using a 1.27mm hex  
wrench), and remove the channel knob metal base. Replace the 16 channel ring  
with the channel stop ring located at the desired channel. Reinstall the channel  
knob metal base, tighten the set screw, and reinstall the channel knob.  
EMERGENCY/  
Automatically selects the pre-programmed Group/System by pressing and holding  
HOME BUTTON for a programmed duration. It can also be used to declare an emergency by  
pressing and holding for a programmed duration. The button must be pre-  
programmed for either operation, but not both.  
PTT BUTTON  
Push-To-Talk must be pressed before voice transmission begins. In trunked mode  
the radio’s ID is transmitted upon depression of the PTT button. Refer to Figure  
8-1 for the location of the PTT button.

8.19 DIGITAL VOICE OPERATION  
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and  
private (encrypted). The voice modes are programmed on a per-group basis within each trunked system.  
8.19.1 Clear Mode  
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice  
signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be  
monitored easily by unauthorized persons.  
Groups or channels programmed for clear operation cannot transmit or receive digital or  
private messages.  
8.19.2 Digital Mode  
The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide  
improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and  
channels programmed for digital operation transmit only digital signals. Message trunked group calls and  
individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the  
call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the  
digital mode is disabled or inoperative.  
If receiving an analog message trunked call, the radio responds in the analog mode during the hang time  
on the working channel.  
If receiving an analog I-Call, the radio responds in the analog mode during the hang time.  
When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is  
transmitted in the mode defined by the system mode as programmed for the current system if the ID being  
called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I-  
Call mode programmed in the list for that ID.  
The overdial DTMF tones are not available while in the Digital Mode.  
8.19.3 Private Mode  
The Private Mode allows the radio to transmit encrypted messages and receive clear or private  
transmissions. The radio transmits private if the group/channel is programmed for private operation and  
forced operation is pre-programmed. If autoselect operation is pre-programmed and the radio is in the  
Private Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang  
time is active, the radio transmits private.  
Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7) different  
cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio. An  
individual key is automatically selected on a per-group/channel basis according to the radio programming.  
Groups and channels within the digital system can be programmed for keys 1-7 (private). Up to 8 banks  
of 7 keys can be stored for private systems. The bank is specified per system.  
When operating on a group or channel programmed for Private Mode, all transmissions are private  
transmissions and the radio receives clear and private signals. The status icon is displayed when the  
Private Mode is enabled. If the selected group or channel is programmed for auto-select capability, the  
mode may be toggled between private and clear with the key, then following the selection mode rules.  
Radios programmed for forced private operation do not allow a change of the transmit mode.

8.19.3.1 Displaying the Currently Used Cryptographic Key Number  
To Display the Currently Used Cryptographic Key Number for either the system encryption key (for  
special call such as individual, phone, all, agency or fleet) or the group/channel key (for group or  
conventional calls), perform the following procedure:  
1. Press the button.  
2. Use the or button to select "DISP KEY."  
3. Then use the or button to toggle between displaying the system key (Figure 8-8) or the  
group/channel key (Figure 8-9).  
Figure 8-8: System Encryption Key Display  
Figure 8-9: Group/Channel Encryption Key Display  
8.19.3.2 Key Zero  
All cryptographic keys can be zeroed (erased from radio memory) by pressing the button and while  
still pressing this button, press and hold the button. Press both buttons for 2 seconds. A series of beeps  
will begin at the start of the 2 second period and then switch to a solid tone after the keys have been  
zeroed. The display will indicate KEY ZERO.  
If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the  
radio before private communications may continue.  
8.19.4 Private Operation  
8.19.4.1 Receiving an Encrypted Call  
When receiving, the radio automatically switches between clear or private operation. If the transmission  
being received is an encrypted transmission, it will be decrypted, the icon is displayed, the receiver will  
unsquelch and the message will be heard in the speaker. For this to occur, the selected group or channel  
must be programmed for private operation and the correct cryptographic key must be loaded into the  
radio.

MM23772, Rev. B  
8.19.4.2 Transmitting an Encrypted Call  
1. Select the desired group or channel.  
2. Place the radio in Private Mode by pressing key, and then follow the selection mode rules. On a  
System radio, the key can be used to toggle the Private Mode ON/OFF. When Private Mode is  
enabled, the icon is displayed.  
If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also,  
the Private Mode will be enabled if forced operation has been programmed in the radio.  
If a group or channel is not programmed for Private Mode operation, PVT DISwill be displayed if  
an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel  
in Private Mode.  
If the radio does not have the correct encryption key loaded, NO KEY#will be displayed and the call  
will not be transmitted.  
3. Continue with standard transmission procedures. A Private Mode access tone will be heard when the  
PTT button is pressed.  
8.19.4.3 Scanned Group Calls  
Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang  
time, if the radio was programmed for autoselect, it will transmit back in the same mode it received the  
call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same  
group was available in private and entered in the scan list, it can receive clear and private calls, provided  
autoselect was programmed in the radio. The user can select transmitting on the scanned or selected  
group. If a group is entered in the scan list more than once and in different modes (clear, digital, private),  
only the first occurrence of the group will be used.

If the radio scans to a group other than the selected group then receives a call on the selected  
group, the radio will switch to the selected group. However, if the “scanned-to” group is  
programmed at a higher priority the radio will remain on the “scanned-to” group.  
The radio will continue scanning if a new group is selected when scan is ON.  
3. Pressing the PTT button when scan is ON will cause the radio to transmit on the displayed group or to  
the currently selected group (depending on programming).

8.21 SCANNING TRUNKED SYSTEMS  
The radio can be programmed with the following System Scan features. These features are automatically  
enabled when the radio is powered ON. A key or menu option is also defined to allow the System Scan  
features to be toggled during radio operation. The System Scan state will be maintained through system  
changes but will default to ON when the radio is powered ON.  
Enable/Disable via Menu Selection:  
Press and then use the or buttons to scroll through the selections until SYS SCANis displayed.  
Then press to toggle the System Scan state. The SYSC ON or SYSC OFF display message is  
displayed for two seconds to show the new state.  
Enable/Disable via Pre-Programmed Keypad Key:  
Press the key pre-programmed to toggle System Scan and the SYSC ONor SYSC OFFdisplay message  
is displayed for two seconds to show the new state.  
8.21.1 Wide Area System Scanning  
The P7200 series radio can be programmed for Wide Area System Scan operation for roaming across  
mobile systems. Upon the loss of the currently selected system's control channel, radios can be  
programmed to automatically scan the control channels of other systems. If a new control channel is  
found, the radio will switch to the new system and sound an alert tone.  
8.21.2 Priority System Scan  
The radio can also be programmed for Priority System Scan. The priority system is the desired or  
preferred system. While receiving the control channel of the selected system, the radio will periodically  
leave the selected system and search for the control channel of the priority system. This is done at a  
programmable rate defined by the value in the Priority Scan Time control (unless the ProScanalgorithm  
is enabled, as explained in the following sections). This priority scan timer is reset each time the PTT  
button is pressed or when the call is received. If the priority system control channel is found, (or meets the  
predefined criteria <ProScan>), the radio will automatically switch to the priority system.  
8.21.2.1 Enabling the Wide Area System Scan Function  
If the radio cannot find the control channel of the selected system and begins to wide area system scan,  
the radio will only scan for the priority system control channel if the priority system is in the wide area  
scan list.  
8.21.2.2 When ProScan is Enabled  
The radio monitors the priority system and will switch to the priority system if the criteria defined by the  
controls in the ProScan Options dialog box are met. If ProScan is enabled, the rate at which the radio will  
scan for the priority system is defined by the System Sample Time control, located in the ProScan  
Options dialog box. See Section 8.21.3 for more information on ProScan  
8.21.3 ProScan  
The radio may be programmed for ProScan system scan operation for multi-site applications depending  
on the version of radio flash code. ProScan is an improved multi-site system scanning algorithm designed  
to replace ProSoundscanning. ProScan provides the radio with the ability to select a new system for the  
radio to communicate on, when the selected system drops below a predefined level. This is accomplished  
by enabling each radio to analyze the signal quality of its current control channel and compares it with the  
67  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
MM23772, Rev. B  
signal quality of the control channel for each site in its adjacent scan list. (The signal quality metric used  
for the ProScan algorithm is based on a combination of both Received Signal Strength Indicator (RSSI)  
and Control Channel Verification (CCV) measurements.) When the selected system degrades to a pre-  
programmed level, the radio will begin to look for a better control channel. Once a control channel that  
exceeds the pre-programmed parameters is found, the radio will change to the new system and emit a tone  
(if enabled through programming). If the control channel is completely lost, the radio will enter Wide  
Area System scanning and search the programmed adjacent systems until a suitable control channel is  
found.  
8.22 EMERGENCY OPERATION  
The radio's ability to declare an emergency, clear an emergency, remain locked on an emergency system  
and group, and the emergency audio and display freeze can each be enabled or disabled through  
programming. When an emergency is declared scanning will stop and restarts only after the emergency  
has been cleared.  
8.22.1 Receiving an Emergency Call  
When receiving an Emergency Call on the selected group and system, an alert beep is heard and is  
displayed. The message *RXEMER*flashes in the display on line two until the emergency condition is  
cleared.  
8.22.2 Declaring an Emergency Call  
To send an emergency call to a selected system and group (or on an optionally pre-programmed group):  
1. Press and hold the red EMERGENCY button that is on top of the radio in front of the antenna for  
approximately one second (this time is programmable and therefore could be longer or shorter; check  
with the system administrator). The radio will transmit an emergency call request with the radio ID  
until an emergency channel assignment is received.  
2. When the working channel assignment is received, the radio sounds a single beep indicating the radio  
has auto keyed (see Table 8-2) and is ready for voice transmission. *TXEMER*flashes on line two in  
the display until the emergency is cleared.  
3. Press PTT and speak into the microphone in a normal voice. and momentarily turn ON.  
4. Release PTT when the transmission is complete.  
To clear the emergency first press and hold the button. While continuing to hold the button, press  
the EMERGENCY button. (This will work if the radio is programmed to clear emergencies.)  
8.23 INDIVIDUAL CALLS  
8.23.1 Receiving and Responding to an Individual Call  
When the radio receives an individual call (a call directed only to the user's radio), it un-mutes on the  
assigned working channel and displays . The first line on the display shows the logical ID number of the  
unit sending the message, or the associated name if the ID number is found in the individual call list. The  
radio can be programmed to ring when an individual call is received. If enabled, the ring begins five  
seconds after the caller un-keys and will continue until the PTT button, the button or the individual  
call mode is entered.  
68

MM23772, Rev. B  
The volume of the ring is adjustable through the volume control levels.  
If a response is made by pressing the PTT to the call prior to the programmed call-back time-out, the call  
will automatically be directed to the originating unit. If a response is not made before the call-back time-  
out, the radio will return to normal receive display, and *WHC*will appear on the first line of the LCD.  
To respond after the call-back time-out, press the key. The radio's display will show the callers ID on  
the first line and WHCI=1 on the second line. Pressing the PTT button at this point will initiate an  
individual call back to the original caller.  
The radio stores the IDs of the last 10 callers in the Calls Received List as shown. Individual calls are  
stored in the top half of the list (1-10) and Group calls are stored in the bottom half of the list (1-10). The  
most recent call is stored in position 1, the second most recent call is stored in position 2, etc.  
Figure 8-10: Calls Received Lists  
To access this list, press the key twice. Use the or buttons or buttons to scroll through  
the list. Pressing the key will display the time elapsed since the call was received. After pressing an  
example of the display is shown in Figure 8-11:  
Figure 8-11: WHC Individual Call Display  
Pressing PTT will initiate an individual call to the displayed logical ID. Powering the radio OFF and ON

8.24.3 Dual-Tone Multi-Frequency: Overdial/Conventional Mode  
Once the radio has established a connection to the public telephone system, it may be necessary to “over-  
dial” more digits to access banking services, answering machines, credit card calls, or other types of  
systems that require Dual-Tone Multi-Frequency (DTMF) access digits.  
Overdial operation can also be used to initiate a telephone interconnect call via DTMF signalling if a dial  
tone has already been accessed on the system. This method makes a telephone interconnect call while  
operating in the conventional mode but will also function in trunked mode if a dial tone is directly  
accessible.  
Telephone numbers and other number sequences for overdialing can be stored in the phone list when  
programming the radio. These numbers are accessed by pressing , then following the selection mode  
rules. The following steps are required to dial these numbers:  
P7250 Model Radio:

This overdial select/entry mode remains active until dropped, cleared, or is pressed. The overdial  
select/entry mode can be re-entered if the call is still active by pressing .  
8.25 PROGRAMMABLE ENTRIES  
8.25.1 Pre-Storing Individual and Telephone Interconnect Calls from the  
Keypad  
Individual Call ID numbers, telephone numbers and other number sequences for overdialing are stored in  
the special calls lists when programming the radio. The first ten entry locations of these lists can be  
changed by the radio operator. The keypad is used when adding, changing, and storing numbers in these  
entry locations.  
Use the following procedure to store a number in one of the first ten entries of a special call list:

entries will accept up to 5 digits. The phone call list entries accept a combination of up to 31 digits  
and pauses.  
4. Press and hold until the display changes indicating that the number has been stored.  
Repeat steps 1-4 above if the number stored in an entry location needs to be changed.  
8.26 STATUS/MESSAGE OPERATION  
Status operation permits the transmission of a pre-programmed status condition to the P25 Trunked or  
EDACS site. Message operation permits the transmission of a pre-programmed message text to a P25  
Trunked or EDACS site.  
8.26.1 Status Operation  
To send a status condition, press the key followed by or key to select the pre-programmed  
status. STATUS and 0 through 9 pre-programmed status selections are available from the menu. If  
STATUS is selected you need to enter the number of the status message you intend to transmit. If no  
status has been programmed for the selected number key, the radio will display NO ENTRY. A valid  
selection will permit the status text to appear in the display for a pre-programmed time. After the time-out  
73  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
MM23772, Rev. B  
expires or the key has been pressed (the key will override the time-out period), the status is selected  
and will be transmitted to the site or stored in the radio memory where it can be polled by the site at a  
future time. Status messages can also be programmed for single key operation so that a single press of a  
key assigned to a status message automatically transmits that message. If the site does not receive the  
status properly, the radio will sound a low pitched tone.  
The status selection can also be cancelled by pressing the CLEAR button prior to the time-out period.  
To view the currently selected status after it has been transmitted, press the key and then the key to  
ramp to STS, re-press the key again and then the CLEAR button prior to the time-out period. If the  
status was not sent successfully to the site, the text associated with the status will flash in the display.  
8.26.2 Message Operation  
Message Operation is performed in the same manner as status operation in the previous section.  
8.27 DYNAMIC REGROUP OPERATION  
Dynamic Regroup Operation permits multiple talk groups (up to eight) to be added to a radio via the  
system manager. The radio must be pre-programmed to respond to regrouping. Dynamic regrouping will  
not be activated in a radio until the system manager sends an activation message. Each radio that receives  
and acknowledges the regrouping instructions is successfully regrouped.  
Pressing and holding the button for 2.5 seconds toggles the user into and out of the dynamic regroup  
groupset. A double beep will sound for entry or exit. The display will indicate REGRP_0xwhere "x" is a  
digit of 1 to 8 indicating the group (when dynamic regroup has been enabled by the user). If the radio is in  
dynamic regroup and the user selects a group that has not been regrouped, the display will show NO  
ENTRY. The radio will be prevented from transmitting and receiving calls in this condition except for  
scanned groups.  
8.27.1 Emergency Operation  
If the pre-programmed groupset on the currently selected system contains an EMER/HOME group and  
the radio is in dynamic regroup, the radio will declare the emergency on the currently selected dynamic  
group.  
8.28 MACRO KEY OPERATION  
Macro key operation permits the user to accomplish a series of keystrokes with a single "macro"  
keystroke. Each Macro Key is capable of executing up to twenty (20) keystrokes, to any push button input  
(i.e., keypad keys, OPTION buttons, etc.). Each macro key can be pre-programmed to activate when  
pressed or when released.  
A macro key may also be pre-programmed to change the key stroke sequence the next time the macro key  
is activated.  
For detail operation and assignment of macro keys, contact your communications supervisor or  
administrator.  
8.29 PORTABLE DATA  
The P7200 series portable radios, when operating in the P25 Trunked or EDACS configuration, permit  
either voice or data calls to be transmitted or received. The radio can handle only one type of call at a  
74

MM23772, Rev. B  
time; however, either data or voice is selected transparently by the operator through normal usage of the  
radio. Data communications is not supported in the conventional mode.  
The radios can be connected to Mobile Data Terminals (MDT) or to a host computer. Any RS-232  
compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) may be  
connected to the radio. Support for MDTs or host computers is a programmable option per radio.  
Additionally, radios may also be programmed for data only operation (no voice calls transmitted or  
received).  
8.29.1 Displays  
The following will be displayed during the various states of data mode of operation:  
TX DATA

9.17 DIGITAL VOICE OPERATION  
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and  
private (encrypted). The voice modes are programmed on a per-channel basis within each conventional  
system.  
9.17.1 Clear Mode  
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice  
signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be  
monitored easily by unauthorized persons.  
Channels programmed for clear operation cannot transmit or receive digital or private  
messages.  
9.17.2 Digital Mode  
The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide  
improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and  
channels programmed for digital operation transmit only digital signals. Individual phone calls (I-Calls)  
are answered back in the mode in which they were received assuming the call or hang time is still active.  
Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or  
inoperative.  
If receiving an analog I-Call, the radio responds in the analog mode during the hang time.  
When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is  
transmitted in the mode defined by the system mode as programmed for the current system if the ID being  
called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I-  
Call mode programmed in the list for that ID.  
The overdial DTMF tones are not available while in the Digital Mode.

MM23772, Rev. B  
9.17.3 Private Mode  
The Private Mode allows the radio to transmit encrypted messages and receive clear or private  
transmissions. The radio transmits private if the group/channel is programmed for private operation and  
forced operation is pre-programmed. If autoselect operation is pre-programmed and the radio is in the  
Private Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang  
time is active, the radio transmits private.  
Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7) different  
cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio. An  
individual key is automatically selected on a per-group/channel basis according to the radio programming.  
Groups and channels within the digital system can be programmed for keys 1-7 (private). Up to 8 banks  
of 7 keys can be stored for private systems. The bank is specified per system.  
When operating on a group or channel programmed for Private Mode, all transmissions are private  
transmissions and the radio receives clear and private signals. The status icon is displayed when the  
Private Mode is enabled. If the selected group or channel is programmed for auto-select capability, the  
mode may be toggled between private and clear with the key, then following the selection mode rules.  
Radios programmed for forced private operation do not allow a change of the transmit mode.  
9.17.3.1 Displaying the Currently Used Cryptographic Key Number  
To Display the Currently Used Cryptographic Key Number for either the system encryption key (for  
special call such as individual, phone, all, agency or fleet) or the group/channel key (for group or  
conventional calls), perform the following procedure:  
1. Press the button.  
2. Use the or button to select "DISP KEY."  
3. Use the or button to toggle between displaying the system key (Figure 9-8) or the  
group/channel key (Figure 9-9).  
Figure 9-8: System Encryption Key Display  
Figure 9-9: Group/Channel Encryption Key Display  
9.17.3.2 Key Zero  
All cryptographic keys can be zeroed (erased from radio memory) by pressing the button and while  
still pressing this button, press and hold the OPTION button. Press both buttons for 2 seconds. A series of  
beeps will begin at the start of the 2 second period and then switch to a solid tone after the keys have been  
zeroed. The display will indicate KEY ZERO.  
91  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
MM23772, Rev. B  
If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the  
radio before private communications may continue.  
9.17.4 Private Operation  
9.17.4.1 Receiving an Encrypted Call  
When receiving, the radio automatically switches between clear or private operation. If the transmission  
being received is an encrypted transmission, it will be decrypted, the icon is displayed, the receiver will  
unsquelch and the message will be heard in the speaker. For this to occur the selected group or channel  
must be programmed for private operation and the correct cryptographic key must be loaded into the  
radio.  
9.17.4.2 Transmitting an Encrypted Call  
1. Select the desired group or channel.  
2. Place the radio in Private Mode by pressing key, then follow the selection mode rules. On a  
System radio, the key can be used to toggle the Private Mode ON/OFF. When Private Mode is  
enabled, the icon is displayed.  
3. If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also,  
the Private Mode will be enabled if forced operation has been programmed in the radio.  
If a group or channel is not programmed for Private Mode operation, PVT DISwill be displayed if  
an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel  
in Private Mode.  
If the radio does not have the correct encryption key loaded, NO KEY#will be displayed and the call  
will not be transmitted.  
4. Continue with standard transmission procedures. A Private Mode access tone will be heard when the  
PTT button is pressed.  
9.17.4.3 Scanned Group Calls  
Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang  
time, if the radio was programmed for autoselect, it will transmit back in the same mode it received the  
call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same  
group was available in private and entered in the scan list, it can receive clear and private calls, provided  
autoselect was programmed in the radio. The user can select transmitting on the scanned or selected  
group. If a group is entered in the scan list more than once and in different modes (clear, digital, private),  
only the first occurrence of the group will be used.

Applies power to and adjusts the receiver’s volume. Rotating the control  
clockwise applies power to the radio. A single alert tone (if enabled through  
programming) indicates the radio is operational.  
Rotating the control clockwise increases the volume level. Minimum volume  
levels may be programmed into the radio to prevent missed calls due to a low  
volume setting. While adjusting the volume the display will momentarily indicate  
the volume level (i.e. VOL=31). The volume range is from a minimum  
programmed level of zero (displayed as OFF in the display) up to 31, which is  
the loudest level.  
Selects systems or group/channels (depending on programming). This is a 16-  
position rotary knob.  
CONTROL KNOB

10.17DIGITAL VOICE OPERATION  
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and  
private (encrypted). The voice modes are programmed on a per-channel basis within each conventional  
system.  
10.17.1 Clear Mode  
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice  
signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be  
monitored easily by unauthorized persons.  
Channels programmed for clear operation cannot transmit or receive digital or private  
messages.  
10.17.2 Digital Mode  
The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide  
improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and  
channels programmed for digital operation transmit only digital signals. Individual phone calls (I-Calls)  
are answered back in the mode in which they were received assuming the call or hang time is still active.  
Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or  
inoperative.  
If receiving an analog I-Call, the radio responds in the analog mode during the hang time.  
When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is  
transmitted in the mode defined by the system mode as programmed for the current system if the ID being  
called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I-  
Call mode programmed in the list for that ID.  
The overdial DTMF tones are not available while in the Digital Mode.

MM23772, Rev. B  
10.17.3 Private Mode  
Private Mode allows the radio to transmit encrypted messages and receive clear or private transmissions.  
The radio transmits private if the group/channel is programmed for private operation and forced operation  
is pre-programmed. If autoselect operation is pre-programmed and the radio is in the Private Mode, the  
radio transmits in the mode of the received call if the hang time is active. If no hang time is active, the  
radio transmits private.  
Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7) different  
cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio. An  
individual key is automatically selected on a per-group/channel basis according to the radio programming.  
Groups and channels within the digital system can be programmed for keys 1-7 (private). Up to 8 banks  
of 7 keys can be stored for private systems. The bank is specified per system.  
When operating on a group or channel programmed for Private Mode, all transmissions are private  
transmissions and the radio receives clear and private signals. The status icon is displayed when the  
Private Mode is enabled. If the selected group or channel is programmed for auto-select capability, the  
mode may be toggled between private and clear with the key, then following the selection mode rules.  
Radios programmed for forced private operation do not allow a change of the transmit mode.  
10.17.3.1 Displaying the Currently Used Cryptographic Key Number  
To Display the Currently Used Cryptographic Key Number for either the system encryption key (for  
special call such as individual, phone, all, agency or fleet) or the group/channel key (for group or  
conventional calls), perform the following procedure:  
1. Press the button.  
2. Use the or button to select "DISP KEY."  
3. Then use the or button to toggle between displaying the system key (Figure 10-8) or the  
group/channel key (Figure 10-9).  
Figure 10-8: System Encryption Key Display  
Figure 10-9: Group/Channel Encryption Key Display  
10.17.3.2 Key Zero  
All cryptographic keys can be zeroed (erased from radio memory) by pressing the button and while  
still pressing this button, press and hold the button. Press both buttons for 2 seconds. A series of beeps  
109  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
MM23772, Rev. B  
will begin at the start of the 2 second period and then switch to a solid tone after the keys have been  
zeroed. The display will indicate KEY ZERO.  
If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the  
radio before private communications may continue.  
10.17.4 Private Operation  
10.17.4.1 Receiving an Encrypted Call  
When receiving, the radio automatically switches between clear or private operation. If the transmission  
being received is an encrypted transmission, it will be decrypted, the icon is displayed, the receiver will  
unsquelch and the message will be heard in the speaker. For this to occur the selected group or channel  
must be programmed for private operation and the correct cryptographic key must be loaded into the  
radio.  
10.17.4.2 Transmitting an Encrypted Call  
Select the desired group or channel.  
1. Place the radio in Private Mode by pressing key, then follow the selection mode rules. On a  
System radio, the key can be used to toggle the Private Mode ON/OFF. When Private Mode is  
enabled, the icon is displayed.  
2. If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also,  
the Private Mode will be enabled if forced operation has been programmed in the radio.  
If a group or channel is not programmed for Private Mode operation, PVT DISwill be displayed if  
an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel  
in Private Mode.  
If the radio does not have the correct encryption key loaded, NO KEY#will be displayed and the call  
will not be transmitted.  
3. Continue with standard transmission procedures. A Private Mode access tone will be heard when the  
PTT button is pressed.  
10.17.4.3 Scanned Group Calls  
Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang  
time, if the radio was programmed for autoselect, it will transmit back in the same mode it received the  
call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same  
group was available in private and entered in the scan list, it can receive clear and private calls, provided  
autoselect was programmed in the radio. The user can select transmitting on the scanned or selected  
group. If a group is entered in the scan list more than once and in different modes (clear, digital, private),  
only the first occurrence of the group will be used.

repairing any defective or damaged part or parts thereof, (ii) by making available at Seller’s factory any  
necessary repaired or replacement parts, or (iii) by replacing the failed Equipment with equivalent new or  
refurbished Equipment. Any repaired or replacement part furnished hereunder shall be warranted for the

nonconformity of the Equipment, whether the claim is in contract, warranty, tort (including negligence),  
strict liability or otherwise, and however instituted. Upon the expiration of the warranty period, all such  
liability shall terminate. The foregoing warranties are exclusive and in lieu of all other warranties, whether  
oral, written, expressed, implied or statutory. NO IMPLIED OR STATUTORY WARRANTIES OF  
MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE SHALL APPLY. IN NO EVENT  
SHALL THE SELLER BE LIABLE FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, INDIRECT OR  
EXEMPLARY DAMAGES.
