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.
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 radio is in the Key Lock mode, the channel will not
change and the three (3) beep error signal will sound.
Transmit Power Output
Your radio can Transmit selectively at one-half ( 1 ⁄
2
) or
two (2) watts of power. Cobra ® 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 one-half (
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.

Getting Started Getting Started
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 counter-clockwise.
Power Saver
Your radio has a unique circuit designed to extend battery
life. If there are no transmissions within ten (10) 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.
U.S.A./International/Canada Channel Maps
Three (3) sets of VHF Channel Maps have been established
for marine use in the U.S.A, Canada, and the rest of the
world (international). Most of the channels are the same
for all three (3) maps, but there are definite differences
(see information on pages 14 to 21). Your radio has all
three (3) 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
Weather/UIC button for three (3) seconds.
The U, I, or C icon will blink on the LCD.
Repeat step 1 to shift to the next channel map(s).
