Narrow band operation
The radio is prepared for narrow band operation. If narrow band
operation is selected (see BAND on page 25), the number of channels are
doubled in the maritime channels, according to international
recommendations. Refer to the channel table in Channels on page 2.
Channels are clearly identified with a preceding 4- or 2-digit, while
operating in narrow band mode. Narrow band radios will not always be
completely compatible with wide band operating radios.
For single narrow band configured private channels or "ALT" channels,
an “n” is displayed next to the channel designator.
Alive beep
To enable “ALIVE” function do as follows:
1. Select the channel where ALIVE function is desired to be transmitted.
2. Press and hold the Hi/Lo until you see “ALIVE ON” on the radio
display. It takes approx. a second.
3. Now “ALIVE” is transmitted by a "beep" on the working channel, with
approx. 4-second intervals.
To deactivate “ALIVE” function do as follows:
• Press and hold the Hi/Lo pressed until “ALIVE ON” no longer appears
on the radio display. It takes approx. a second.
Note
Prior to any initiation of scrambling, the operator must always
identify the calling station in clear voice (unscrambled) on that
channel. Use of scrambling may also be restricted by national
laws.
