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 Of The Following:
a.
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 the 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

Transmit Power Output
Your radio can transmit selectively at one (1) or twenty-five (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:
1.
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.
If, in an emergency, you need to increase the output power
on these channels 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:
1.
Check to see that your unit is set to a proper
channel for the type of message you plan to send.

3. With the microphone about two (2) inches (5 cm) from
your mouth, press and hold the
Talk button and speak into
the microphone.
Transmit will be indicated on the LCD.
4. Release the Talk button when you are finished speaking.

response to your message unless the
Talk button is released.

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

Talk button is released, it can be pressed
again to resume transmission.
