2 SAFETY TRAINING INFORMATION
The M/A-COM P7200 and P5200 portable radios generate 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 and P5200 portable radio have been tested and comply with the FCC RF exposure limits for
“Occupational Use Only.” In addition, these M/A-COM radios comply 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).

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

MM23772, Rev. F
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 and P5200 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd), Nickel
Metal Hydride (NiMH), or Lithium Ion (Li Ion) batteries. Please follow the directions below to maximize
the useful life of each type of battery.
Do not disassemble or modify Lithium Ion battery packs. The Lithium Ion battery
packs are equipped with built-in safety and protection features. Should these
features be disabled or tampered with in any way, the battery pack can leak acid,
overheat, emit smoke, burst, and/or, ignite.
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
selecting option 7.

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 specifically designed for charging nickel-based and lithium ion battery packs.
The chargers are chemistry-specific for the battery packs and automatically adjust the charging profiles
accordingly. 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 M/A-COM battery packs using a 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
Both nickel-based and Lithium Ion batteries vary in capacity and life. NiCd batteries have a longer life
cycle than NiMH batteries whereas NiMH batteries have a larger capacity. However, both Nickel-based
and Lithium ion type batteries require basic usage guidelines be followed in order to optimize 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 nickel-based 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. Lithium Ion batteries do not suffer from
memory-effect and therefore do not require conditioning.
Do not leave any M/A-COM battery in a charger for more than a few days.

5 INTRODUCTION
The P7200 and P5200 series radios are dual-band multi-mode portable radios. The P7200 series radio is
available without a front mounted keypad (P7200 only), with a 6-buttoned front mounted keypad, and
with a DTMF front mounted keypad (P7200 only). The dual-band (700/800 MHz) P7200 portable radio
delivers end-to-end encrypted digital voice and IP data communications. The P7200 and P5200 are
designed to support multiple operating modes including:
•
•
•
•
•
OpenSky® Trunked mode (OTP)
EDACS® or ProVoice™ Trunked mode
P25 Trunked mode
P25 Digital Conventional mode
Conventional Analog mode
The P7200 and P5200 portables can include all of these modes or just one. Additional modes of operation
can be added with software updates.
The P7200 and P5200 support 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 or P5200.
For further detail about features and operation refer to the appropriate maintenance manual or contact

8.8 PERSONALITY
As illustrated in Figure 8-4, 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 (16) talk groups.
8.8.1
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.

8.9 OPENSKY DISPLAY OVERVIEW
The 12-character x 3-line display shows the radio status. The first two lines of the display are text lines
that change in response to user interaction with the menu buttons. Status icons appear in the bottom line
(line 3) of the display (see Table 8-2).
8.9.1
Display’s Top Line
The display’s top line of text changes as the ꢀ and ꢁ buttons are pressed to scroll through the
available menu options (see Table 8-4). When the dwell display is present, the selected talk group will be
displayed. Other information, such as alert messages will scroll across the top line of the display.
8.9.2
Display’s Second Line
The second line will displays information such as active menu, log in prompt, emergency status, and
dwell display messages as described in the following section.
8.9.3
Dwell Display
When not engaged in menu selection, the first two lines of the display default to the user-defined display,
known as the “dwell display.” The top line indicates the currently selected talk group. The second line
will display the currently selected profile, caller ID/alias1, received talk group, and current channel name.
Press the ꢄ button repeatedly to scroll through and view one of these second line options.
1 Alias is a logical ID name such as “J_Smith.” The name corresponds to a user ID such as 003-542-0001.

MM23772, Rev. F
When a key on the DTMF keypad is pressed, the DTMF tone is played through the radio’s speaker.
8.14 CHANGE THE ACTIVE PROFILE
The radio can store up to sixteen (16) standard profiles, one of which is the currently active profile. To
change the currently active profile:
1. Press the ꢀ or ꢁ buttons until “ProfileMenu” is displayed.
2. Use ꢂ or ꢃ to scroll through the list of available profiles.
3. Profile becomes active when selected for longer than 2 seconds, when the ꢄ is pressed, or when the
menu is changed using the ꢀ or ꢁ button. Press ꢄ to activate the selected profile.
8.15 CHANGE THE SELECTED TALK GROUP
Each profile stored in the radio can have up to sixteen (16) talk groups. One talk group within the
currently active profile is set as the “selected talk group.” To change the selected talk group, turn the
Group Selection knob on top of the radio.
8.16 ADJUST DISPLAY AND BUTTON BACKLIGHT BRIGHTNESS
1. Press the ꢀ or ꢁ buttons until “Bright Menu” is displayed.
2. Use ꢂ or ꢃ to brighten or dim the display and button backlighting.
8.17 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.
8.17.1 Enable Stealth Mode
P7270 Model: Press 2# to toggle Stealth Mode On.
P7270 and P7250 Models: Press the ꢀ or ꢁ buttons to scroll through menus until “StealthMenu”
appears in the display. To immediately activate Stealth Mode press the ꢂ or ꢃ 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.
8.17.2 Disable Stealth Mode
P7270 Model: Re-enable all lighting, side tones, and exit Stealth Mode by pressing 2# or via the Stealth
Mode menu.
P7250 Model: Re-enable all lighting, side tones, and exit Stealth Mode by pressing any key other than
PTT or Emergency. This returns to the Dwell Display.

MM23772, Rev. F
On P7250 model radios, when stealth mode is 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.
8.18 ADJUST 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 to set side tone level:
1. Press the ꢀ or ꢁ buttons to cycle through the menu until “Side Menu” is displayed.
2. Press ꢂ or ꢃ to change to the desired level (Off, Low, Medium, and High). To turn side tones
completely off, use the “Off” setting.
8.19 CHANGE OPERATING MODE
P72720 Model Radios Only:
Press 1# to transition from OTP to ECP. If ECP is not loaded in the radio, “No App” will be displayed.
P7250 and P72720 Model Radios:
1. Press the ꢀ or ꢁ buttons to cycle through the menu until “App Mode” is displayed.
2. Press ꢂ or ꢃ to select the desired operating mode.
3. Press ꢄ and use ꢂ or ꢃ to select Y or N.
4. Press ꢄ again to make selection and return to the dwell display.
8.20 RECEIVE AND TRANSMIT 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.
8.20.1 Receive a Voice Call
No action is required on the part of the user.
No action is required to receive a voice call. The display responds to incoming voice calls as follows:
•
When the dwell display is set to received talk group and the scan mode is Normal or Fixed:
a. If the received talk group matches the selected talk group, then the alias (if available) or user id of
the incoming caller is displayed.
40

MM23772, Rev. F
b. If the received talk group does not match the selected talk group, then the received talk group
name is displayed.
•
•
When the dwell display is set to received talk group and the scan mode is None, the radio only
receives voice on its selected talk group. When the call is received, the alias (if available) or the user
ID of the incoming caller is displayed.
When the dwell display is not set to received talk group, then there is no display indication of an
incoming call.
8.20.2 Transmit 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.
8.21 ADJUST 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 ꢂ or ꢃ to increase or decrease level. There are four levels available: low, medium, medium-
high, and high.
3. Press ꢄ or wait a few seconds to return to the dwell display.
8.22 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.
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.

MM23772, Rev. F
P1 and P2 groups CANNOT be locked out.
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.
8.22.1 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 ꢂ or ꢃ 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 ꢄ key to select the lockable talk group.
4. “<” appears next to the locked out talk group.
8.22.2 Unlock a Talk Group
1. Use the ꢀ or ꢁ buttons to scroll through the menu choices until “LockOutMenu” appears in the
display.
2. Use the ꢂ or ꢃ 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 ꢄ 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.
8.23 SCANNING
8.23.1 Select 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

Table 8-7: Scan Modes
EXPLANATION
SCAN
MODE
Eliminates distractions.
Full communications (listen and talk) with the active talk group.
No calls received from other talk groups.
No Scan
This is the default setting.
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.
Priority (P1 and P2) groups are user selectable.
Receive calls from more than one talk group, if available from the current site.
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.
Functions the same as Normal Scan Mode, except 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.
Fixed
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.

The scanning priority settings are reset to the default values when the radio is turned
off.
8.24 MAKE 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.
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.

8.25 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.
8.25.1 Define 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 can be up to 200 characters long.

8.27 EMERGENCY COMMUNICATIONS
The P7200 and P5200 portable radios are 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.
Table 8-10: Emergency Calls vs. Emergency Alerts
EMERGENCY ALERT
EMERGENCY CALL
An Emergency Alert message is sent to the dispatcher console. All
peers (radios and consoles) and the dispatch console play the
emergency tone whenever an emergency call is detected. An
emergency tone plays for each new emergency, or when a profile
is changed, (assuming there is an emergency on one of the talk
groups for the new profile).
An Emergency Alert message is
sent to the dispatcher console. The
dispatch
console
plays
an
emergency tone when it receives
the message.
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.
In addition to the Emergency Alert signal, the microphone goes hot
No emergency audio (voice) for a predetermined length of time to allow for emergency audio
transmission (hot-mic) capability (voice) transmission. The radio declaring the emergency has
available (per programming by channel access priority. Note that the User can also use the PTT
system administrator).
after the pre-determined hot-mic audio transmission, or during to
extend the initial hot-mic audio transmission.
8.27.1 Declare an Emergency Call or Alert
1. Press the red emergency button on the radio to enter emergency mode. Emergency is raised after the
Emergency Raise Delay (configurable via programming). Default is 1 second.
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.
If the attempt is unsuccessful, “E-PEND” flashes periodically and a retry is queued for 10 seconds. If
unsuccessful because of lost sync, retry occurs immediately upon reacquiring sync. On each retry attempt,
radio temporarily displays “E-RETRY.” This process repeats until the emergency is successfully
declared.
8.27.2 Receive 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). When
receiving voice in an active emergency, the flashing “EMERGENCY” is inhibited so that the alias of the
sender can be seen.
With “No Scan,” only the emergency tone is heard, not the initial open mic transmission.
To dismiss or ignore the emergency, refer to Section 8.27.3.
8.27.3 Dismiss 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 ꢄ 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.
8.27.4 Clear an Emergency
Check with your system administrator to ensure that your radio is configured with the
ability to clear an emergency.
To clear the emergency, first press and hold the ꢃ button. While continuing to hold the ꢃ button, press
the EMERGENCY button. Release both buttons when the Emergency Cleared Tone sounds.
If the radio is in stealth mode, clearing the emergency will cause the radio to exit stealth
mode.

8.28 OPENSKY ENCRYPTION (P7200 ONLY)
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.
8.28.1 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.
8.28.1.1 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 network administrator level, “Secure Call”
will appear in the bottom line of the dwell display if the user is logged in to that talk group.
If a secure call is in progress elsewhere and the user has not logged in, the bottom of the dwell display
will alternate between “No Access” and the alias of the radio that is currently engaged in the secure call.
8.28.2 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.
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.
51

MM23772, Rev. F
8.28.2.1 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, the user
will see “Secure Call” on the bottom of the dwell display.
If a secure (encrypted) call is in progress, and the user has not entered the key, the bottom of the dwell
display will alternate between “No Access” and the alias of the radio that is currently engaged in the
secure call.
Once the user has terminated manual encryption, “UnSecure” appears temporarily in the bottom line of
the dwell display.
8.29 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.
8.30 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].
8.31 V-TAC FUNCTIONS
8.31.1 Extended Coverage Modes (“XCOV” and “XCOV-TG”)
In addition to all standard portable radio operating capabilities, Extended Coverage adds the V-TAC’s
bridging (vehicular repeat) functionality for accessing the OpenSky radio network. Each portable radio
connected to the V-TAC using Extended Coverage is considered a “client” on the V-TAC. Extended
Coverage benefits portable radio users since it allows them to get network connectivity using the
V-TAC’s higher transmit output power and better antenna system.
52
Download from Www.Somanuals.com. All Manuals Search And Download.
MM23772, Rev. F
The V-TAC supports two Extended Coverage modes: Extended Coverage for individual users (XCOV)
and Extended Coverage for a talk group (XCOV-TG). Typically, Extended Coverage is used after the
vehicle’s operator has exited the vehicle with a portable radio unit and the portable unit requires this
bridging functionality to access the OpenSky radio network.
The V-TAC takes advantage of OpenSky’s TDMA capability to eliminate interference between its local
and network radio links when operating in an Extended Coverage mode (XCOV or XCOV-TG), an
undesirable characteristic of many traditional vehicular repeater systems. Because the V-TAC employs
this technology, interference on the network and local radio links is minimized.
A V-TAC in XCOV or XCOV-TG mode sends its alias to clients. The alias is displayed in the second line
of the dwell menu of the client, (“VA <alias>”). The client must be connected to a V-TAC running
version OTP14.4 or for the V-TAC to provide the alias to the client. If the client is connected to a V-TAC
running version OTP14.3.1 or earlier, the client displays “VA None.”
8.31.2 Change Between Extended Coverage Modes
By default, the specific Extended Coverage mode utilized, either XCOV or XCOV-TG, is determined by
commands sent to the V-TAC and portable radios from the system administrator or radio installation
personnel. In other words, these commands determine which Extended Coverage mode the V-TAC and
radios normally use and determine the access method that must be employed by a portable radio to
connect to the V-TAC. After commands of this type are sent to the V-TAC and portable radios, each must
be rebooted (powered off and then back on) before the change takes effect.
A radio can manually override this command-determined default mode by entering *61 # or *62 # or by
using the Client Mode menu option. Command *61 # sets the radio to use the XCOV mode and *62 # sets
the radio to use the XCOV-TG mode. However, the connection will only be successful if the V-TAC
operating mode matches the manually selected portable V-TAC mode.
8.31.3 Use the XCOV Mode
The Extended Coverage for individual users (XCOV) mode allows up to eight (8) client radios to connect
to the V-TAC. The radios have full radio functionality including selective calling and mobile data.
With the Extended Coverage for individual users’ mode (XCOV), V-TAC configuration defines which
portable radios are permitted V-TAC access.
Connecting to the V-TAC is automatic or manual, as determined by the system administrator and
configuration. Automatic is the preferred mode.
8.31.3.1 Manually Access the XCOV Mode
P7270 Model Radios Only:
1. Enter the command *61 # to set the radio to use the XCOV mode.
2. Press *60 # to disconnect from the XCOV mode.
P7250 and P7270 Model Radios
1. Press ꢀ or ꢁ until the Client Mode menu appears.
2. Press ꢂ or ꢃ until XCOV is displayed.
3. Press ꢄ to confirm mode selection. The radio reverts to the dwell display and the V-TAC icon is
displayed.
53

MM23772, Rev. F
8.31.4 Use the XCOV-TG Mode
When using the XCOV-TG mode, up to thirty (30) client radios can connect to the V-TAC. However,
unlike XCOV, radios connected to using XCOV-TG are limited to communicating only on the
XCOV-TG talk group and emergency communications. Advanced features such as selective calling and
mobile data operations are not available to the XCOV-TG connected clients.
The talk group used for XCOV-TG communications is the talk group that was selected at the V-TAC
when it entered XCOV-TG mode. Before a radio can connect to the V-TAC the talk group must be
selected on the P7200. If this talk group is not provisioned in the radio’s personality, the radio cannot
connect to the V-TAC via the XCOV-TG mode. While connected to the V-TAC via XCOV-TG, a
different talk group or profile cannot be selected.
When a portable radio is connected to the V-TAC via XCOV-TG, the V-TAC forwards only the network
voice traffic on the XCOV-TG talk groups. Also, data transactions are limited to RRM messages from the
V-TAC to the portable radio.
8.31.4.1 Radio Limitations Using XCOV-TG
Portable radios connected to the V-TAC via XCOV-TG will not channel-scan unless they lose radio
frequency contact with the V-TAC. If manually enabled, radios will not scan network channels.
The following portable radio keypad functions are disabled when the radio is connected to the V-TAC via
the XCOV-TG mode: log-off, manual log-in, alerts, selective calls, PSTN calls, and speed dial calls.
The following portable radio menus are disabled when the radio is connected to the V-TAC via the
XCOV-TG mode: alert destination, alert message, alert received, priority talk group, and scan mode. The
user cannot change talk group or profile.
8.31.4.2 Access the XCOV-TG Mode
For the Extended Coverage for a talk group mode (XCOV-TG), a portable radio user is granted access
and connects to the V-TAC by simply selecting the same Talk Group that the V-TAC had selected when
it entered the XCOV-TG mode. Contact the system administrator for questions regarding these aspects.
During XCOV-TG mode operations, the V-TAC will not disconnect portable radios connected to it. A
portable radio user must manually disconnect from the V-TAC by pressing *60 # on the radio’s keypad.
However, if the V-TAC is switched out of the XCOV-TG mode, all portable radios will be automatically
disconnected from the V-TAC. The radios will continue to look for another V-TAC until manually
disconnected (*60 #).
P7270 Model Radios Only:

9 EDACS AND P25 TRUNKED OPERATION
9.1 TURN 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 9-1 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.
9.2 CONTROLS
The radio features two rotary control knobs and an emergency button mounted on the top of the radio
(Figure 9-1). Push-To-Talk and option buttons are mounted on the side (Figure 9-1). The front mounted
keypad of the P7270 System model has 15 buttons and the P5250 and P7250 Scan models have six
buttons. The P7230 Select model does not have a front mounted keypad.

9.2.1
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=40). The volume range is from a minimum programmed
level of zero (displayed as OFFin the display) up to 40, 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
9-1 for the location of the PTT button.
SIDE OPTION
Exits the current operation (removing all displays associated with it) and returns
the radio to the selected talk group. Terminates individual and telephone
interconnect calls.
BUTTON 2 ꢃꢅ
SIDE OPTION
Activates one of a number of programmable software options selected during PC
programming. Programmable options include hi/low power settings, keypad lock,
LCD contrast, LCD and keypad back lighting.

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.
9.19.2 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.
9.19.3 Private Mode (P7200 Only)
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 ꢄ key, then following the selection mode rules.
Radios programmed for forced private operation do not allow a change of the transmit mode.

All cryptographic keys can be zeroed (erased from radio memory) by pressing the ꢃ button and while
still pressing this button, press and hold the ꢂ 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.
9.19.4 Private Operation (P7200 Only)
9.19.4.1 Receive 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.

9.19.4.2 Transmit an Encrypted Call
1. Select the desired group or channel.
2. Place the radio in Private Mode by pressing ꢄ key, and then follow the selection mode rules. On a
System radio, the ꢋ 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.
9.19.4.3 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.

9.21.1 Wide Area System Scanning
The P7200 and P5200 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.
9.21.2 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 ProScan™ algorithm
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.
9.21.2.1 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.
9.21.2.2 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
9.21.3 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 ProSound™ scanning. 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
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.
9.22 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.
9.22.1 Receive 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.
9.22.2 Declare 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
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.

9.23 INDIVIDUAL CALLS
9.23.1 Receive and Respond 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 ꢃ button or the individual
call mode is entered.
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 ꢓ 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.

9.24.3 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 ꢄ, then following the selection mode
rules. The following steps are required to dial these numbers:
P7250 and P5250 Model Radio:
1. Follow the procedure in Section 9.24.2 to establish a connection to the telephone system or consult
the system administrator for the procedure to access a dial tone on the trunked or conventional

9.25 PROGRAMMABLE ENTRIES
9.25.1 Pre-Store 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:
1. Press ꢓ or ꢒ to enter the individual call list or the phone call list. is displayed.
2. Scroll through the list using the ꢀ or ꢁ until one of the first ten entries is reached. NO ENTRYis
displayed if the location is empty.
3. Enter the desired number. If necessary, a pause can be entered by pressing and holding 0-9, ꢓ, or
ꢒ until an underscore appears in the display (telephone interconnect only). The individual 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 ꢄ 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.
9.26 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.
9.26.1 Status Operation
To send a status condition, press the ꢄ 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

MM23772, Rev. F
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
expires or the ꢄ key has been pressed (the ꢄ 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 ꢄ key and then the ꢀ key to
ramp to STS, re-press the ꢄ 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.
9.26.2 Message Operation
Message Operation is performed in the same manner as status operation in the previous section.
9.27 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 ꢃ 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.
9.27.1 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.
9.28 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.

9.29 PORTABLE DATA
The P7200 and P5200 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 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).
9.29.1 Displays
The following will be displayed during the various states of data mode of operation:
TX DATA

appear on the top line in the display for two seconds then the display will return to normal.
•
•
Pressing the “no data” (ND) key toggles data state ON or OFF.
Clearing an emergency. (Valid only if the emergency caused “Data OFF” operation.)
9.29.4 Exit Data Calls
Under normal conditions, the radio enters the scan lockout mode and returns to the control channel after
completion of a data call (transmit or receive). If, during a data call, one of the following conditions
occurs, the data call is immediately terminated and the radio performs the desired function:
•
•
•
PTT is activated.
Emergency is declared by pressing the pre-programmed emergency button.

10.17 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.
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.

10.17.3 Private Mode (P7200 Only)
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 ꢄ 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 Display 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 ꢄ button.
2. Use the ꢀ or ꢁ button to select "DISP KEY."

10.17.3.2 Key Zero
All cryptographic keys can be zeroed (erased from radio memory) by pressing the ꢃ 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.

MM23772, Rev. F
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 (P7200 Only)
10.17.4.1 Receive 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 Transmit an Encrypted Call
1. Select the desired group or channel.
2. Place the radio in Private Mode by pressing ꢄ key, then follow the selection mode rules. On a
System radio, the ꢋ 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.
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.
