Position Request and Reply
Requesting another station’s position (POS Request)
Anytime you need to know where another boat currently is—to find your boating partners,
to respond to a request for assistance, etc.—you can send a position request to their radio:
1. Press CALL-MENU to display the call menu.
2. Select DSC Call sub-menu, then select POS Request.
3. The radio displays the names listed in your directory; use CHANNEL UP and CHANNEL DOWN
to choose the directory entry you want to contact and press ENT-1W/25W . If you want to
contact a station that is not in your directory, select Manual. The radio prompts you to
enter the MMSI number you want to call. Enter the MMSI number the same way you
enter directory entries (see page 19). Enter all nine digits and press ENT-1W/25W .
4. The radio displays the MMSI number you are about to contact and asks you to confirm.
If you want to request the position of the displayed MMSI number, select Send. To cancel
the request, select Cancel.
5. When the other station responds, the radio displays the MMSI number, the longitude,
and the latitude of the other station. If your radio is connected to a chartplotter through
the NMEA OUT connection (see page 31), the position information will also be displayed
on the plotter screen.
6. If the other station does not have valid GPS data, the radio displays No Position.
Receiving a position request (Position Reply)
When another station requests your current position, the radio displays the following screen:
To send your current position to the other station, select Reply; the radio transmits your
latitude and longitude to the other station. If you select Reply but the radio does not have
valid GPS data, it transmits the reply code with No Position.
To reject the position request, select Cancel.
Enabling automatic position reply
If you want the radio to automatically transmit your current position whenever it receives a
position request, you can enable automatic position reply. Most boaters activate automatic
position reply for safety reasons or because they subscribe to a marine towing service.
Sometimes—for example, in some competitive situations--you may not want other stations
to get your position without your manual confirmation
1. Press and hold CALL-MENU to display the normal menu.
2. Select Setup and then POS Reply.
3. Choose Auto and press ENT-1W/25W . The radio will automatically transmit your position
when it receives a position request.
