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. In most cases, a reply will be forthcoming. If for some reason, your request
is not acknowledged in five (5) minutes, the user will be prompted to Resend the
request or exit the menu.
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
POS REQST (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.
6. Press the Call/Set button. Your radio will send the
position request and there will be one (1) of three (3)
possible responses:
■ You will receive the position.
■ You will receive a no position data response, meaning the
station you queried is not connected to a GPS device and
cannot send its position.
■ You will receive a no reply response, meaning the operator of
that station has chosen not to reply to your request.
