Receiving an All Ships Call
All Ships calls sent by stations within range of your radio will sound
the distress alarm on your radio and switch your radio to Channel 16.
When an all ships call is heard:
1. Press any button to turn off the alarm and return to
Standby mode.
2. Read and write down the MMSI of the vessel sending
the call as well as the date and time of the call in case
you will want to respond.
3. Listen to the voice message sent on the channel your
radio was switched to by the incoming all ships call.
Sending a Geographical Call
Your radio cannot send Geographical calls. Only large ships and shore
stations with specially equipped radios can send these calls.
Receiving a Geographical Call
Geographical calls are sent by specially equipped radios to all stations in a
particular geographical area to alert only those stations of the call and not
stations in unaffected areas. If you are in an area to which a Geographical
call is made, it will sound the geographical alarm on your radio and switch
your radio to the channel chosen by the sending station.
When a geographical call is heard:
1. Press any button to turn off the alarm.
2. Read and write down the MMSI of the vessel
sending the call as well as the date and time
of the call in case you will want to respond.
3. Listen to the voice message sent on the channel your
radio was switched to by the incoming geographical call.
4. Press one of the following three buttons to switch from
geographical call receive to Standby mode: Call/Set
button, Channel 16 button, or Talk button.

Sending an All Ships Call
A DSC All Ships call is used for the same urgency and safety purposes as the Pan
Pan and Securite voice calls as well as to send routine messages to all stations at
once. It will reach all stations within range of your radio. If you have an urgent, but
not life-threatening, situation or a safety warning to broadcast to all vessels in your
area, this is the type of call to use. It should be used judiciously for routine calls.
To send an all ships call:
1. In Standby mode, select a channel on which you want
to communicate for a routine call. (The radio will use
Channel 16 for urgent and safety calls.)
2. Press the Call/Set button to enter the Call Send menu.
3. Use the Up/Down buttons to scroll to
ALLSHIPS
.
4. Press the Call/Set button to move to the message
type menu.
5. Use the Up/Down buttons to select a message type
—
URGENCY
,
SAFETY
or
ROUTINE
.
6. Press the Call/Set button to send the message.
7. Depending on the type of message you chose,
the radio will automatically switch to a voice channel.
a. After urgency and safety calls, the radio will switch
to Channel 16 and wait for you to press the Talk button
to send the urgent or safety message by voice.
b. After a routine call, the radio will switch to the channel
you selected in step 1 and wait for you to press the
Talk button to send the routine message by voice.
DSC equipped radios that receive your message will be
automatically switched to Channel 16 or the channel you
selected to hear your voice message.
To return to Standby mode without sending a message,
use the Up/Down buttons to scroll to
EXIT
and
press the Call/Set button.
