FCC Radio License and MMSI Number Information

In U.S. waters, vessels which are not required to carry radio equipment

are not required to have an FCC (Federal Communications Commis-

sion) ship station license for a VHF marine radio.

However, any vessel required to carry a marine radio on an interna-

tional voyage, carrying a HF single side band radio telephone or marine

satellite terminal must have an FCC license.

License application forms for ship and land stations can be downloaded

free from the FCC web site at this address: www.fcc.gov/formpage.html.

You may also order copies of these forms by calling the FCC Forms Dis-

tribution Center at 1-800-418-3676.

At this time, the FCC does not require recreational boaters to have a

ship radio station call sign. The U.S. Coast Guard recommends using

the boat's registration number and state.

The BoatU.S. MMSI Program has been certified by both the Federal

Communications Commission (FCC) and the U.S. Coast Guard to as-

sign MMSI numbers to vessels with DSC capable radios. To obtain and

FCC Radio Frequency

Compliance Requirements and Warnings

When operating your marine radio transceiver, you should know that

the antenna radiates radio frequency (RF) energy. This radio was de-

signed to meet the FCC’s rules and regulations for the maximum per-

missible exposure to radio frequency energy. This design was tested

and found to be compliant with the strict requirements established by

the FCC.

DO NOT operate the radio without a proper antenna attached, because

this may damage the radio and may also cause you to exceed FCC RF

exposure limits. Antenna types suited for this radio are described in the

installation section.

DO NOT transmit for more than 50% of the total radio use time.

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” is displayed on the screen. You can cause the

radio to transmit by pressing the "PTT" (Push To Talk) switch.

IMPORTANT: The antenna(s) used for this transmitter must be in-

stalled to provide a separation distance of at least 91 cm (37 inches)

from all persons (including passengers). The antenna(s) must not ex-

ceed an antenna gain of 3 decibels (dB) and must not be co-located or

operating in conjunction with any other antenna or transmitter.

Section 1: Installation

Introduction

Thank you for purchasing the Lowrance LVR 850 DSC VHF Radio. We

know you’re anxious to try it out, but first, let us explain how this

manual can help you get the most out of your new radio.

We have designed this book so you don’t have to read the whole thing

from front to back to find the information you want. At the start of each

segment, we’ll tell you what content is coming up next. If it’s a concept

you're already familiar with, we’ll show you where to find the next im-

portant topic.

We lead off the manual with proper Distress Call procedures on page 4.

We put it at the front of the book to make it easy to find in case of an

emergency.

The first section covers LVR-850 installation and specifications.

The second section, Basic Radio Operation, goes over some basic func-

tions of the radio and includes instructions on how to set up your MMSI

(Maritime Mobile Service Identity) number. You can't make a call

without it! To jump to MMSI setup, flip to page 8. To acquire a

free MMSI number, see the web address on the bottom of page

ii.

The third section, Advanced Radio Operation, offers more detailed in-

formation about the radio's features. The section will touch on all as-

pects of the radio's functionality, providing clear and complete explana-

tions via a convenient alphabetical layout.

Let’s get started!

Powering Your Radio

(Power Supply cable – red and black wires)

The unit works from a 12-volt electrical system. You may attach the

radio to a 12-volt battery or to an auxiliary power panel.

If possible, keep the power cable away from other boat wiring, especially

the engine's wires. This will provide the best isolation from electrical

noise. The power cable has two wires, red and black. Red is the positive

lead, black is negative or ground. Make sure to attach the in-line fuse

holder to the red lead as close to the power source as possible.

Auxiliary Wires

The white and black auxiliary wires on the back of the unit connect

your radio to an external speaker. Connect the white (+) wire to the

speaker's positive lead, and connect the black (–) wire to the speaker's

negative lead.

Download from Www.Somanuals.com. All Manuals Search And Download.

The remaining auxiliary wires are used for DSC (Digital Selective

Calling) service, where the radio can exchange latitude and longitude

position information with a GPS (Global Positioning System) receiver

in NMEA 0183 format.

Caution

All of the auxiliary wires have bare ends for easier installation.

The bare ends on any unused wires could cause an electrical

short if left exposed. To prevent this, you should cover the indi-

vidual wire ends – either by capping them with wire nuts or

wrapping them with electrical tape.

Bracket Installation

Mount the unit in any convenient location, provided there is clearance

behind the unit when it's tilted for the best viewing angle. You should

also make sure there is enough room behind the unit to attach the

power, antenna and auxiliary cables. Pick a location far enough from

any compass to avoid compass deviation caused by the speaker magnet.

The radio must be installed at least three feet from the antenna. Make

sure there is space nearby to hang the mic clip.

Holes in the gimbal bracket's base allow wood screw or through-bolt

mounting. You may need to place a piece of plywood on the back side of

thin fiberglass panels to reinforce the panel and secure the mounting

hardware. We suggest that you use stainless steel screws for installa-

tion.

Front

Install the gimbal bracket, which looks similar to the one pictured

here. Place the bracket so the arms slope toward the radio's front.

Once a location is determined, use the bracket as a template and mark

the mounting holes. Screw the bracket to the mounting surface. Be sure

to leave enough slack in the cables to allow tilting the unit.

Attach the unit to the gimbal bracket using the supplied gimbal knobs

and washers. Attach the cables and the unit is ready to use.

Antenna

A good antenna installation will optimize the performance of your ma-

rine radio. There is no height requirement for antenna installation, but

the higher it is mounted, the better the reception. That's because ma-

rine VHF radio signals travel only on a "line of sight" basis. An ideal

installation will give the antenna a clear view of the horizon in all di-

rections.

The antenna may be mounted on a gunwale, rail or on flat surfaces like

a deck, roof or bulkhead. In the case of some sailboats and powerboats,

it may be attached to a mast or mast-like structure.

When installing your VHF marine antenna, be sure to keep it at least

three feet away from any other antenna or metal object. The antenna

also must be installed three feet away from the radio, and at least three

feet from any passengers or crew. Refer to the antenna manufacturer's

instructions for further installation information. You must also make

Download from Www.Somanuals.com. All Manuals Search And Download.

sure your antenna and its installation complies with all local and fed-

eral regulations. Never operate your radio unless it is connected to the

antenna.

The antenna must not exceed an antenna gain of 3 decibels (dB). The

antenna cable requires a PL259 connector, and the cable connects at

the back of the radio. For installations less than 25 feet, use RG58 co-

axial cable. For installations greater than 25 feet, use RG-8/U coaxial

cable.

WARNINGS:

Using an antenna with gain greater then 3 dB can dam-

age the radio and exceed the safe exposure limits for ra-

dio frequency (RF) energy.

Also, the energy from any VHF radio antenna can be

harmful, even one properly rated at 3 dB of gain! Do not

come in contact with the antenna while a transmission is

being sent. Be sure the antenna is installed where it is

separated from people by at least 3 feet of space.

How to Make a Distress Call

Speak slowly, clearly and calmly.

1. Select VHF Channel 16.

2. Press microphone button: "MAYDAY — MAYDAY— MAYDAY."

3. "THIS IS [your ship ID]."

4. "MAYDAY [your ship name]."

5. Tell where you are — what navigational aids or landmarks are near.

6. State the nature of your distress.

7. Give number of persons aboard and condition of any injured.

8. Estimate present seaworthiness of your ship.

9. Briefly describe your ship — meters, type, color, hull.

10. "I WILL BE LISTENING ON CHANNEL 16."

11. End message by saying "THIS IS [ship name/call sign] OVER."

12. Release the PTT key and listen. Someone should answer. If not, re-

peat call, beginning at Item 3 above.

WARNING

The following types of communication are prohibited by

the FCC: false distress calls; calls to any boat — exclud-

ing emergencies and radio tests; calls to or from a vessel

on land and obscene or profane language. Using obscene

or profane language could result in a fine of up to

$10,000.

Section 2: Basic Radio Operation

This section addresses the radio’s basic operations, which includes

MMSI (Maritime Mobile Service Identity) number setup. If you already

have your MMSI number programmed into the radio and have a strong

understanding of the radio's basic functions, move on to Section 3:

Advanced Radio Operation.

The Lowrance LVR-850 VHF

Marine Radio.

We're going to kick off the operation section with a brief description of

the radio's basic functions. That will be followed by some important in-

formation on Digital Selective Calling and basic instructions on how to

make and receive calls.

Using the Keypad

The keypad has eight keys: H/L (Hi/Lo), WX (Weather), 16/9 (Priority

Channels), SCN (Scan), MEM (Memory), CALL (Call) and ↑ ↓, the up-and-

down arrow keys. When you press any of the keys a tone will sound. If

you push a key and a 3-beep tone sounds, there is an error or the func-

tion is not supported by the radio. You’ll notice several functions re-

quire you to hold down a key for a few seconds. In those cases, a single

beep sounds, then, after a few moments, a second beep will be heard to

let you know you have successfully changed the mode.

Power/Volume

The volume knob at the top right of the radio’s face is used to power up

the LVR 850. Turn the knob clockwise to turn on the radio. The unit

will start on Ch. 2, then switch to Ch. 16, its default priority channel.

Squelch

Squelch, the bottom knob on the radio’s face, helps the unit screen out

radio traffic resulting from signals that are too weak to transmit any-

thing but noise. To adjust the squelch, turn it to the left until noise can

be heard. Turn it back to the right until the noise is eliminated.

will transmit at 25 Watts.

WX (Weather)

Dark clouds on the horizon? Press the WX key to enter the WX (WEATHER)

MODE and get the latest weather information. Use the ↑ ↓ keys to change

the WX channel.

16/9 (Priority Channel)

The 16/9 key is used to switch between priority channels. It also allows

you to exit various operation modes, ignore incoming calls and cancel

outgoing calls.

NOTE

Ch. 16 and Ch. 9 may only be used to make initial contact with a

vessel and nothing more. When there is an emergency, all Distress

calls will be broadcast on Ch. 16.

SCN (Scan)

The SCN (scan) key allows you to monitor numerous channels at the

same time. Scanning options include: PRIORITY SCAN, MEMORY SCAN AND

ALLSCAN.

MEM (Memory)

The MEM key may be used to initiate a Memory Scan and gives you the

option of adding or deleting channels from the radio's scan list memory.

CALL

By pressing the CALL key you can make a new call, return the last in-

coming call, place a call to all ships or to one of up to 10 stored MMSI

numbers from a saved directory.

DISTRESS

By lifting up the red cover and holding down the DISTRESS button for

three seconds, you will send a distress call to the Coast Guard and any

other ship within range of you.

Arrow Keys

Use the ↑ ↓ keys to scroll through the channels and various menu op-

tions.

PTT (Press to Talk)

The PTT key is the talk button on the microphone. Press and hold it

down to talk when making or receiving a call.

DSC Calling vs. non-DSC Calling

The LVR-850 supports two types of calls, Digital Selective Calls (DSC)

and non-Digital Selective Calls. A non-DSC call is the traditional

method where an individual hails another vessel on Ch. 16, then asks

the other party to switch to a working channel set aside for the desired

communication type. Once they have left Ch. 16 and the selected

working channel is clear, the individual hails the vessel again to initi-

ate communication.

What is a DSC call?

A relatively new technology, digital selective calling (DSC) gives you

the capability to dial another boat directly via the vessel's MMSI (Mari-

time Mobile Service Identity) number, which functions much like a

phone number. Digital Selective Calling simplifies the calling process,

because you don't have to hail the vessel on Ch. 16 nor do you have to

verbally direct them to the working channel you want them to switch to

for communication. When their DSC radio receives your call, it auto-

matically will switch to the channel you selected for communication.

The primary reason DSC was created was to enhance boater safety. It

does this in several ways. When working in tandem with a GPS unit, it

helps the Coast Guard respond more quickly to a Distress Call, since

the location of the vessel in distress will be automatically transmitted

when the signal is sent out. It will automatically repeat a distress sig-

nal every four minutes. That would come in handy if, as in the case of a

fire, you could not man the radio and fight the fire at the same time.

DSC calling also helps cut back the transmission traffic on Ch. 16, the

emergency priority channel.

How DSC works

A digital selective call uses a digital signal to transmit a pack of infor-

mation that can include, the caller’s MMSI number, the MMSI of the

ship or ships being called, call priority and a frequency or mode re-

quest. Location and time of location may be entered manually or if an

active GPS unit is attached, transmitted automatically. DSC calls allow

you to contact a specific ship, a group of ships, a specific group of DSC

receivers, ships in a particular geographic area or all ships within

range of you. A DSC call may even be patched into a regular phone line

through a commercial coastal station. One of the key elements of a DSC

call is the ability to place an individual call directly to another vessel.

Simplex or Duplex

References to simplex and duplex channels are scattered throughout

this manual. Simplex channels transmit and receive messages on the

same frequency. Like a CB radio, only one message can be transmitted

at a time. A duplex channel transmits and receives messages on differ-

ent frequencies. Like a telephone, it gives users the capability to

transmit and receive messages at the same time. You must choose a

simplex channel when making a DSC call!

MMSI (Maritime Mobile Service Identity)

Your Maritime Mobile Service Identity number (MMSI) is like a home

phone number. Other DSC (Digital Selective Calling) radios must enter

your number before they can contact you. But first, you must program

your number into your radio. If your MMSI number is not set up, the ID

ANNUNCIATOR will blink on the display.

CAUTION

You only have one chance to program your MMSI into your ra-

dio. Study this section carefully to ensure the MMSI is entered

correctly.

Download from Www.Somanuals.com. All Manuals Search And Download.

The figure above illustrates the MMSI number entry of 992344513.

If a valid MMSI is already stored in the radio's memory, you will not be

able to enter a MMSI number. If a 9-digit MMSI number has not been

programmed into the radio, you will not be able to make or receive DSC

calls. To enter your assigned MMSI number, follow the steps listed in

the MMSI Setup below.

Warning

Again, there is only one chance to do this procedure cor-

rectly, so go over this section carefully.

MMSI Setup

1. Hold down the CALL key for 5 seconds. The ID ANNUNCIATOR will blink

and a large "0" will be displayed alongside a small “16.” The big number

“0” is the MMSI digit you are entering and the small digit “16” is the

first MMSI character field position. For example, a small digit "2" rep-

resents the 2nd number from the left in your assigned MMSI. If the

number was "4" it would mean the big digit you were entering was the

4th number from the left and so on.

This example gives us a closer look at a number sequence from a MMSI

entry. The big numbers are the MMSI digits. The small numbers in the

lower right hand corner represent the digits' character field position.

The big digit 4 is the sixth number from left in the MMSI. The big digit

5 is seventh from left and the big digit 1 is eighth from left.

NOTE

You need only to modify the big (MMSI) digits. The small digits

(character field position of the MMSI digit) will be generated auto-

matically.

2. Use the ↑ ↓ keys to enter the first digit of your MMSI number, then

press the MEM key to advance to the second digit. The small digit now

displays the 2nd character position with a big-digit "0" and small-digit

"2”. Press the ↑ ↓ keys to set the second MMSI digit and touch the MEM

key to store. Repeat the operation until all 9 digits have been entered.

After inputting your MMSI, press the MEM key to double-check each

digit.

NOTE

If there is an error in the entry procedure, press the 16/9 key to exit.

You can also turn off the radio to ensure the MMSI won't be stored.

After you are satisfied with the MMSI number you have entered, hold

down the CALL key for 5 seconds to store the number. The ID ANNUCIATOR

will stop blinking and the radio reverts to the main screen. Now you are

ready to make a DSC call.

Choosing a Channel

Before making a call to another vessel, check the VHF chart in the back

of this manual. You'll have to choose a simplex communication channel

authorized for the type of communication you desire.

Making a Call

The LVR-850 supports five DSC call types: ALLSHIPS CALL, DIRECTORY CALL,

LAST CALL, NEW CALL and DISTRESS CALL. The example below details a NEW

CALL. For information on the other call types, see page 13.

To place a DSC call

New Call

1. Select a simplex channel and press the CALL key once. LAST blinks.

2. Use the ↑ ↓ keys to select NEW CALL.

3. Press the CALL key again. You can now enter the MMSI data of the

vessel you want to contact.

4. Use the ↑ ↓ keys to enter the MMSI numbers, pressing MEM after

each digit. After completing MMSI entry, press the MEM key to verify

each number of the MMSI.

5. Press the CALL key and the radio will transmit the request. If there

is no ACK after 4 seconds, the radio transmits the call again. The radio

will stay in standby mode until an ACK is received, indicated by the

flashing ID Annunciator. If an ACK is not received, you can press the

call key again and the call is placed again. You can exit the call func-

tion at any time by pressing the 16/9 key twice.

CAUTION

Before transmitting, monitor the selected simplex channel to make sure

it is clear. This is a FCC requirement.

To place a non-DSC call:

When making a non-DSC call, you'll have to switch to a communication

channel after making initial contact, so be sure to select a channel

authorized for the type of communication you desire.

1. Select an appropriate communication channel.

2. Tune your radio to Ch. 16 or Ch. 9. Speak slowly and clearly, stating

the name of the vessel you are trying to contact followed by "this is

(your ship name and call sign)."

3. When the other vessel responds, say "go to (the desired channel num-

ber) over."

4. Switch to the other working channel. After you are sure it is clear,

call out to the other vessel, stating the vessel's name, followed by "this

is (your ship name and call sign)."

Receiving a Call

Reception of an individual call automatically establishes communica-

tion on the working channel requested by the caller. Your radio trans-

mits an ACK (Acknowledgement) message back to the calling radio. If

the calling vessel’s MMSI matches a number stored in your directory,

the number's directory location is shown. If no match is made, the ID

ANNUNCIATOR blinks. If you want to respond to the calling vessel, just

press the PTT button on the microphone. Press the 16/9 key to ignore

the call. See page 18 to get more detailed information on call reception.

Section 3: Advanced Operation

This section will give a more detailed explanation of what your radio

can do. We'll start off with a breakdown of the types of DSC calls the

LVR-850 can transmit and receive. That will be followed by a brief de-

scription of how to place a non-DSC call. If you are comfortable with

your knowledge regarding transmission and reception of calls, skip

ahead to page 20 to see how to set up a MMSI Directory. On page 27,

there is information on the radio's weather function.

Calls

Transmission

The five DSC calling modes are:

1. AllShips Call: places a call to any ship in range of you.

2. Directory Call: dials number from MMSI directory.

3. Distress Call: executes an emergency call to Coast Guard and other

ships in range of you.

3. Last Call: dials last incoming call.

4. New Call: places call to caller not in the MMSI directory.

Press CALL then use the ↑ ↓ keys to scroll through the four choices

The example shows the MMSI Data 987776510 being entered.

To change or edit MMSI data, select a FL location and press the MEM

key to change the data. After inputting the 9-digit MMSI, hold down

the CALL key for 5 seconds to store the new MMSI.

DSC Monitor

To be sure the DSC Monitor mode is on, hold down the CALL key for 5

seconds to toggle the DSC Monitor mode off and on. It must be on for

your radio to receive a DSC call. The DSC MON ANNUNCIATOR will be dis-

played onscreen, if Ch. 70 is being accessed. Since there is no independ-

ent Ch. 70 receiver, the radio normally monitors Ch. 70 and checks

other channels on a regular basis to detect a squelch break. This

method ensures the radio will acquire the most DSC calls possible.

DSC Monitor must be

on for radio to receive

calls

NOTE

DSC calls will NOT be received when the radio is receiving or

sending out a transmission. During scanning, Ch. 70 is monitored

on an allocated time-slot basis and DSC calls will be received.

GPS Operation

Your radio is NMEA 0183 compatible, which means it can work with a

GPS unit. To be certain your location is autom+atically transmitted

during a distress call, make sure your GPS unit is on and operational at

all times. The GPS data is sent through Ch. 70 to the coast guard and is

the primary starting point of any search and rescue mission. If THE GPS

ANNUNCIATOR is blinking, the GPS data is not valid.

GPS

Annunciator

H/L

The H/L key gives you control over the radio's wattage. The high-end is

25 Watts. The low-end is 1 Watt. If the LO ANNUNCIATOR is off, the radio

will transmit at 25 Watts. Some channels do not accept transmissions

or are restricted to a 1-Watt level. If you come across one of those chan-

nels and you try to switch to 25W, you will hear a 3-tone error beep,

meaning you either can not transmit on that channel or it only accepts

transmissions at the 1W (Lo) level.

Memory Operation

Normally, the MEM ANNUNCIATOR appears on the display to alert the user

the channel is stored in the memory channel list. The following figure

shows Ch. 8 is stored in memory.

Download from Www.Somanuals.com. All Manuals Search And Download.

You can easily add or delete channels from the memory channel list.

For your safety, DO NOT delete priority Ch. 16.

To add a new channel, use the ↑ ↓ keys to select the desired channel

(shown above in big digits). If the channel is currently stored as a

memory channel, the MEM ANNUNCIATOR will be displayed.

To add a new channel to the list, hold down the MEM key until the MEM

ANNUNCIATOR appears. The new channel is now added to the list. To de-

lete a channel from the list, use the ↑ ↓ keys to choose a channel saved

in the memory list. You will know a channel from the memory list has

been chosen when the MEM Annunciator appears on the screen. Hold

down the MEM key for three seconds to delete the channel. The MEM

ANNUNCIATOR no longer will be displayed when the channel is tuned in.

NOTE

To clear and reset all the memory channels, hold down the MEM key

while turning on the radio. This clears all memory channels with

the exception of the Priority Channel.

Position Send/Request

Transmission

Your radio can send and receive information on location if it is con-

nected to a GPS unit. This will allow you to locate a vessel without

transmitting messages back and forth.

To send your position (P1):

1. Press the CALL key, then use the ↑ ↓ keys to select DIR from the

main screen and press Call.

2. To edit or enter the P1 memory location, use the ↑ ↓ keys to select

position P1 from the directory. P1 will be displayed in the bottom right

corner of the display. If the P1 location has CL in the window, you must

enter the MMSI of the vessel to which you're trying to send your posi-

tion. Press MEM and use the ↑ ↓ keys to enter the MMSI numbers,

pressing MEM after each digit has been entered. When finished, press

and hold the CALL key for five seconds. The screen will show FL P1, let-

ting you know the MMSI is now stored in the P1 location. The MMSI

number will be stored in the P1 location until you edit or replace the

MMSI information.

3. Press the Call key and the big digit will blink and the channel will

switch to Ch. 16. Press the CALL key again and the position data will be

sent through Ch. 70. After the transmission on Ch. 70, the ID Annun-

ciator will flash, indicating it is waiting for an ACK. If an ACK is not

received, another call can be made to send your position to the same

MMSI by pressing the CALL key. When the position send is acknowl-

edged, an alarm will be heard. Press the 16/9 key to cancel the alarm.

4. Press 16/9 key to return to the main screen.

To request a position (P2):

1. Press CALL, then use the ↑ ↓ keys to select DIR from the main screen.

2. To edit or enter the P2 location, use the ↑ ↓ keys to select position P2

from the directory. P2 will be displayed in the bottom right corner of

the display. If the P2 location has CL in the window, you must enter the

MMSI of the vessel from which you're trying to request a position.

Press MEM and use the ↑ ↓ keys to enter the MMSI numbers, pressing

MEM after each digit has been entered. When finished, press and hold

the CALL key for five seconds. The screen will show FL P2, letting you

know the MMSI is now stored in the P2 location. The MMSI number

will be stored in the P2 location until you edit or replace the MMSI in-

formation.

3. Press the CALL key and the big digit will blink and the channel will

be switched to Ch. 16. Press the CALL key again and the position data

will be requested through Ch. 70. After the transmission on Ch. 70, the

ID Annunciator will flash, indicating it is waiting for an ACK. If an ACK

is not received, another call can be made to request the position of the

same MMSI by pressing the CALL key. When the position request is

acknowledged, an alarm will be heard. Press the 16/9 key to cancel the

alarm.

4. Press 16/9 key to return to the main screen. The vessel's location will

be displayed on the GPS map.

Reception

To receive a position send:

the main screen.

2. Press the 16/9 key to stop the alarm.

3. If the MMSI number of the vessel sending its location is in your di-

rectory, its directory location will be displayed. If the vessel is not in

your directory, its MMSI number will be displayed.

4. Press 16/9 to return to the main screen. The vessel's location will be

Priority Channel (16/9)

The 16/9 key is used to switch priority channels. When you first turn on

the radio, its default priority channel is Ch. 16. To switch priority

channels, hold down the 16/9 key for a few seconds until the priority

channel switches to the other channel. This is particularly useful when

you want to make a non-DSC call and Ch. 16 is receiving a lot of

transmission traffic. The 16/9 key also allows you to exit various opera-

tion modes, ignore incoming calls and cancel outgoing calls.

With a quick press of the 16/9 key the priority channel immediately is

selected with high (25W) transmission power. Press the 16/9 key again

and it selects the last used channel.

PTT (Push To Talk)

This key is on the microphone. Press and hold it down to send a trans-

mission. There is a 5-minute maximum transmission timer, per FCC

regulations.

Scan

There are three primary scanning modes, ALLSCAN, MEMORY SCAN, and

PRIORITY SCAN.

Download from Www.Somanuals.com. All Manuals Search And Download.

NOTE

Remember, you cancel any scan mode at anytime by pressing the

16/9 or SCN key.

To start an All Scan

To scan through all available channels, press and hold the SCN key for

three seconds. ALL SCN will appear on the display. The radio now will

scroll through every available channel as it scans.

A noisy channel that interrupts the scanning can be temporarily elimi-

nated from the scan list by holding down the MEM key. The channel re-

ceiving the signal will be skipped, allowing the scanning to continue

uninhibited. Turning the radio off and on again will restore all the

channels back to the ALLSCAN memory list.

To start a Memory Scan

To scan through channels in the memory scan list, press the MEM key,

then push the SCN key. If you are in a different scanning mode, you

must stop the scan before switching to a MEMORY SCAN. In that case,

press SCN|MEM|SCN.

To add channels to the memory scan list, use the ↑ ↓ keys to tune in

each of the channels you want to monitor. As you tune in each channel,

depress MEM for three seconds to add it to the memory list. The MEM

Annunciator will appear, letting you know the channel has been added

to memory..

While in the MEM scan mode, touch the WX key to toggle the WX ALERT

function off and on. The scan will stop when a channel picks up a sig-

nal. The scan will not continue until the input signal stops. To stop

scanning, press the SCN key or the 16/9 key. Press in the PTT button

exits the scan mode at the last channel display.

To start a Priority Scan

Pressing the SCN key activates the PRIORITY SCAN mode. P SCAN will ap-

pear on the display. The priority channel is scanned every 2 seconds,

even if another channel has a squelch break.

When a signal is received on the priority channel, the scan stops and

the radio receives the priority transmission. WX ALERT can be toggled off

and on by pressing the WX key.

Screen

When the unit is turned on the LCD light display is on and stays on.

There is no contrast control.

Weather (Wx)

Dark clouds on the horizon? Press the WX key to enter the WX (WEATHER)

MODE and get the latest weather information. The last used Wx channel

always appears first. Use the ↑ ↓ keys to change the WX channel. In

PRIORITY SCAN or MEMORY SCAN MODES, pressing the WX key allows the WX

ALERT function to be toggled off and on. Select the WX channel before

starting a PRIORITY SCAN or MEMORY SCAN.

If a WX ALERT – a 1050Hz-tone burst transmitted from the NOAA

Weather service – is issued, a special circuit in the radio detects the

tone and during scanning modes (except All Scan), a loud 2-tone warn-

ing will sound. The warning tone is canceled by pressing any key. The

radio will stop scanning and switch to the WX channel to broadcast the

warning. You know the radio is scanning the WX channel, if you see the

WX ANNUNCIATOR flash as it scans through the weather channels.
