Calling all Stations (All-Ships Call)
Using DSC Features

Safety call.
3. The radio asks you to confirm the call. Select Send (press DISP/ENT/
H/M/L) to continue with the call or select Exit (press CLR/VOL ) to
cancel the call.
4. The radio automatically switches to channel 70 to transmit the call
request then automatically switches to channel 16, the designated
response channel for all-ships calling.
All ships calling contacts all DSC radios within range of your boat. You
should only use all ships calling in the event of a Safety warning (such
as debris in the water) or to request assistance in an Urgency (any
situation where your vessel has a serious problem but is not yet in
distress).
Making an Automatic Distress Call
If you have programmed your MMSI number, your radio can transmit
an automated distress call with your current location and nature of the
distress. The radio then monitors channel 16 for a response and repeats
the distress call every few minutes until it receives an acknowledgement.
To send an automatic distress call, press and hold
DISTRESS
for three
seconds. If no MMSI number has been programmed, the radio prompts
you to enter your MMSI number.
If you want to include the nature of your distress in the distress call, use
the following distress procedure:
Undesignated Sinking Fire Overboard
Adrift Flooding Abandoning Capsizing
Collision Piracy, Armed Grounding
Cancelling an Automatic Distress Call
While the radio is waiting for a response, it gives you the option of
canceling the call. To cancel the distress call, press
CLR/VOL.
And
press DISP/ENT/ H/M/L to send a Distress Cancellation call.
