‘P’ will be displayed.
The second priority channel can be user-programmed to any
of the standard marine channels. To program your preferred
channel into the second priority channel;
1. Press and hold the
key. The radio will switch to the
present second priority channel and ‘P’ will be displayed
2. Press and hold the
key again. ‘P’ will disappear and
the channel number will flash.
3. Select the required channel using the

4. Press and hold the
key again. The displayed channel
will be stored as your new second priority channel.
HI/LO POWER
Briefly press the
key to toggle high or low transmitter
power. The display will show ‘HI’ or ‘LOW’ to confirm the
selected power setting.
NOTE:
Some channels may be permanently limited to HI or
LOW power by default. If any of these channels are selected
you will not be able to change the power setting for that
channel. However, for some channels you are allowed to
overrule this restriction temporarily – e.g. channels 13 & 67
in the US channel set.
To temporarily select HI power on these channels, hold the
PTT
then hold the
key. The radio will switch to HI
power. Now while still holding the
key, release the
PTT
followed by the
key. The channel will stay on HI power
for as long as you remain on that channel.
KEY LOCK
Press and hold the
key to lock the keypad. The
icon will be displayed when the keypad is locked and all keys
except the
PTT
and any Distress related keys will be locked.
To unlock the keypad, press and hold the
key again. The
icon will disappear.
BACKLIGHT
The backlight operates automatically whenever any key
(except the
PTT
) is pressed and switches off a few seconds
after the last key press. The backlight provides lighting for the
display and keypad.
SCANNING
Basic Scan
The basic scan function allows the radio to scan all channels
for signals. When a signal is detected the scan pauses to
allow the signal to be heard. Once the signal has gone the
scan resumes.
To activate the scan function, briefly press the
key.
‘SCAN’ appears on the display and the channel numbers
change rapidly as the radio scans for signals.
To deactivate the scan function, briefly press the
key
again. ‘SCAN’ disappears from the display.
