Digital Select Calling (DSC)
Operation
Receiving An Individual Call
When another station makes an Individual call to your radio,
the individual alarm will sound, the caller will be identified
on the LCD, and your radio will ask to be switched to the
channel selected by the caller. Press Call/Set to switch to
requested channel and an acknowledgement will be sent to
caller. If WX/UIC button is pressed, channel doesn’t change
and no acknowledgement will be sent. Press any button to
turn Off the alarm.
To Receive An Individual Call:
1. Press the Talk button and greet the caller —
almost as if you were answering the telephone.
Sending A Group Call
Sending a Group call is very similar to sending an individual call, except that
the group MMSI is used and the resend and DSC responses do not apply.
To Send A Group Call:
1. In Standby mode, select a channel on which you want
to communicate.
2. Press the Call/Set button to enter the Call Send menu.
3. Use the Up/Down buttons to scroll to
GROUP .
4. Press the Call/Set button to move to the send
or exit menu.
5. Use the Up/Down buttons to select SEND or EXIT .
6. Press the Call/Set button to send the message or
return to the Call Send menu if EXIT was chosen.
All radios will be switched to the channel selected in
step 1. Press and hold the Talk button to send your
voice message to everyone in the group.
Anyone in the group can now also transmit on
that channel.
Receiving A Group Call
When another station makes a Group call to your radio, the individual alarm
will sound, the caller will be identified on the LCD, and your radio will be
switched to the channel selected by the caller, just as for an individual call.
Press any button to turn Off the alarm.
To Receive A Group Call:
1. Listen for the group voice message.
2. Press the Talk button and respond
only if appropriate.
Sending A Position Request
Position Request mode enables a DSC radio to obtain the position
(latitude and longitude) of a station that has a GPS device connected
to the DSC radio at that station.
To Request The Position Of Another Station:
1. In Standby mode, select a channel on which
you want to communicate.
2. Press the Call/Set button to enter the
Call Send menu.
3. Use the Up/Down buttons to scroll to
POSREQST (position request) on
the menu.
4. Press the Call/Set button to enter the
Individual Directory menu.
5. Use the Up/Down buttons to scroll to the
name of the station whose position you
want to request.
