Receiving a distress call
When the radio receives a DSC distress call, it:
• Sounds a two-tone alarm through the handset(s) and speaker(s),
and
• Automatically switches to channel 16 after 10 seconds if there is
no user intervention.
If the two-tone distress alarm sounds on your radio:
1. Press the [SILENC] softkey to silence the alert.
You do not need to send a DSC acknowledgement; this will be done
by an official search and rescue station.
2. Maintain a listening watch on Channel 16 for voice communications
from ship and coast stations about the distress.
3. You can then:
• Press ▼ or ▲ to scroll through details of the distress call,
• Press [PTT] to talk, or
• Press [X] to exit the DSC session.
Distress acknowledgement (DISTRESS ACK)
or distress relay all ships (DISTRESS REL)
Only official Search and Rescue stations are permitted to send these
signals.
When your radio receives a Distress Acknowledgement signal it
does the following:
• Cancels any Distress Mode transmissions,
• Sounds a two-tone alert, and
• Automatically switches to channel 16 after 10 seconds if there is
no user intervention.
1. Press the [SILENC] softkey to silence the alert.
2. Press the [ACCEPT] softkey to switch to CH16 immediately.
3. Maintain a listening watch on CH16, and standby to give assistance.
4. You can:
• Press ▼ or ▲ to scroll through details of the call,
• Press PTT to talk to the coast station or other ship, or
• Press [X] to exit the DSC session.
