All-ships calls contact all DSC radios within range of your ship. Only use all-ships calling

Urgency (any situation where your ship has a serious problem but is not yet in distress).

All Ships Call screen appears, showing two options:
SAFETY and URGENCY .
3. Use the PUSH/SEL knob to select either option
and then enter the channel to transmit on. Press
SEND. The next screen displays the type of All
Ships Call sent, the channel the call was sent on,
and a countdown clock. If the radio receives an
acknowledgement, it automatically switches to the
designated response channel.

another countdown clock. You can either resend or
cancel the call.

and displays the MMSI number of the calling station or group and the transmitting channel
for the call.
