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 tables 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 for two seconds. The radio will shift
one channel map and the Active Channel
Map icon on the LCD will show the change
on the LCD.
Repeat step 1 to shift to the next channel map(s).
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 or 5 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 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
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.
Backlight
The LCD will be illuminated by the Backlight when any key is pressed
and will remain on for five seconds after the button is released.
If you need to turn On the backlight
without disturbing any settings:
1. Press the Backlight/Key Lock button. The backlight
will remain On for ten seconds.
If the backlight is On, a press of the Backlight/Key Lock
button will turn it Off.
