Regarding Distress Relay Calls
This radio cannot send Distress Relay calls. Only large ships
and shore stations, with specially equipped radios, can send
Distress Relay calls.
Receiving Distress Relay Calls
This radio does respond to a Distress Relay call just as it
responds to a Distress call.
Sending an All Ships Call
Use the DSC All Ships call for the same urgency and safety
purposes as the Pan and Securite voice calls as well as
sending Routine messages to all stations at once. The DSC
All Ships call reaches all stations in radio range. Use the
DSC All Ships call for urgent, but not life-threatening
situations or to broadcast a safety warning to all vessels in
the area. Use the DSC All Ships call judiciously for Routine
calls.
To Send an All Ships Call:
1. In Standby mode, select a channel to communicate a
routine call. The radio uses Channel 16 for urgent and
safety calls.

menu.
3. Scroll to All Ships.
4. Press Enter button for All Ships Call Select.

sending Urgency and Safety calls.

automatically switches to a voice channel.

Channel switching been turned off.
To return to Standby mode, without sending a message,
