Receiving Distress calls
When the radio receives a Distress call, the 2-tone alarm sounds. The
display shows the bands in which the Distress call is received and the
category of the Distress call. The types of Distress calls are Distress, Distress
ACK, Distress RELAY and DISTR. RELAY ACK.
1. Push the soft key SILENT to switch off the 2-tone alarm.
2. Push VIEW to display further information for this call.
3. Push HOLD to put the call on hold and stay in the communication loop
to receive follow up information, updates etc.
4. Monitor radio communication on the frequency 2182 kHz
(automatically set) as a coast station may require your assistance.
(If Distress is received on HF radio communication, the frequency is
8291 kHz)
5. The radio receives the first Distress acknowledgment call and the 2-tone
alarm sounds again. To switch off the 2-tone alarm push the soft key
SILENT.
6. If you decide to acknowledge the Distress call push the soft key ACK
