Transmit Power Output

Your radio can Transmit selectively at one (1) or 25 watts of power. Cobra

suggests you maintain the low power setting for short-range communications

and to avoid overpowering nearby stations with your signal. Use the high power

setting for long-range communications or when you do not receive a response

to a signal sent at one (1) watt.

To Toggle Between The High And Low Power Modes:

Press the High/Low Power button.

The LCD will show which mode is in effect.

Some channels are restricted to use at a maximum of

one (1) watt. Your radio will automatically set the power

to Low Power mode when you select those channels.

While using the U.S.A. channel map, if, in an emergency,

you need to increase the output power on Channel 13 and

Channel 67 for your signal to be heard, you can override

the Low Power mode by pressing and holding the High/

Low Power button.

Transmit A Message

To Transmit A Message:

Check to see that your unit is set to a proper

channel for the type of message you plan to send.

2. Toggle to the low power setting.

3. With the microphone/speaker about two (2) inches

[five (5) cm] from your mouth, press and hold the

Talk button and speak into the microphone/speaker.

Transmit will be indicated on the LCD.

4. Release the Talk button when you are finished speaking.

Your unit can only operate in either the Transmit or the

Receive mode at any given time. You will not hear the

response to your message unless the Talk button is released.

NOTE

If the Talk button is held down for five (5) minutes,

the radio will automatically cease transmitting to

prevent unwanted signal generation. As soon as

the

Talk button is released, it can be pressed

again to resume transmission.

Voice Transmission

•

Transmit mode gives you the ability to communicate with safety services, other

vessels, and shore stations. When you use this capability, be sure to follow the

procedures and to observe the courtesies that govern its use so everyone benefits.

(The tables on pages 14 through 23 will help you select the proper channels.)

Before pressing the Talk button to transmit a message, you should select the

appropriate channel and transmit power output.

Channels

You can transmit voice messages on most VHF Channels. Refer to the VHF marine

channel assignments on pages 14 through 23 to select a channel according to the

type of message you are going to send.

To Change The Channel You Can Choose

From One (1) Of The Following:

Press the Up/Down buttons. This will take you to the

next higher or lower VHF channel. (When on Channel

88A, the next higher channel is Channel 1 and vice

versa.) For rapid advance, press and hold the

Up or

Down buttons. (The confirmation tone will sound

only for each button press, not during rapid advance.)

Channel 16 with one (1) press and to Channel 9 with

a second press. Additional presses will toggle between

Channel 16 and Channel 9. Press and hold the
