Channels
Your radio will receive and transmit VHF signals on
the Channel indicated on the LCD. You can change
the Channel at any time using the Channel Up and
Channel Down buttons.
To change channels:
1. Press the Channel Up or Channel Down button.
If you are on Channel 88, pressing the
Channel Up
button will advance to Channel 1. If you are on
Channel 1, pressing the Channel Down button
will advance to Channel 88.
You can hold the
Channel Up or Channel Down
button for fast advance.
The beep sound will occur only at the first press
of the button and not during fast advance.
If the new channel selected is restricted to low power,
the radio will automatically switch to Low Power mode
and the Low Power icon will appear on the LCD.
If the radio is in the
Key Lock mode, the channel will
not change and the three-beep error signal will sound.
Transmit Power Output
Your radio can Transmit selectively at
1
⁄
2
or 2 watts
of power. Cobra Electronics Corporation
™
suggests
you maintain the low power setting for short-range
communications, to conserve battery life 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
1
⁄
2
watt.
To toggle between the High
and Low Power modes:
1. Press the High/Low Power – Lock button.
The LCD will show which mode is in effect.

Volume
The On-Off Power/Volume knob also controls the speaker
Volume. The Volume adjustment applies only to what you
hear from the speaker and does not affect the Volume of
your outgoing messages, which is controlled by the
circuitry of your radio.
To increase the volume:
1. Turn the On-Off Power/Volume knob clockwise.
To decrease the volume:
1. Turn the On-Off Power/Volume knob anticlockwise.
Power Saver
Your radio has a unique circuit designed to extend battery
life. If there are no transmissions within ten seconds, the
radio will automatically switch to Power Save mode and
the Save icon will flash in the LCD. This will not affect the
radio’s ability to receive incoming transmissions.
International/Canada/U.S.A. Channel Maps
Three sets of VHF Channel Maps have been established
for marine use internationally, in Canada and in the U.S.A.
Most of the channels are the same for all three maps,
but there are definite differences (see information on
pages 12 – 21). Your radio has all three maps built
into it and will operate correctly in whichever area
you choose.
To set your radio for the area
in which you will be using it:
1. From Standby mode, press and hold the UIC button.
The U, I, or C icon will blink on the LCD.
Repeat step 1 to shift to the next channel map(s).
