Digital Selective Calling Receiving Position Request Calls You can configure your radio reply automatically to incoming position requests, to prompt you to review and approve the incoming requests before replying, or to ignore incoming requests (see page 27 for more information). If you enable automatic position replies, the screen displays "SENDING POSITION CALLING" and sends your position when receiving a position request. After the call has been transmitted successfully, the screen displays "POSITION SENT". When receiving a position request, "POS. REQUEST FROM [VESSEL NAME or MMSI NUMBER]" is displayed on the screen. If GPS data is available, press OK to send the position reply. If GPS data is not available, the screen displays "NO GPS DATA. UNABLE TO COMPLY". Receiving Position Send Calls When receiving a position send call (position report), "POS. SEND FROM [VESSEL NAME or MMSI NUMBER]" is displayed on the screen with the position data. Select OK to return to the Home screen. Receiving Group Calls 1. When receiving a group call, "GROUP ROUTINE" is displayed on the screen. The radio prompts you to change to the requested channel. If the channel request is for an invalid channel, "INVALID CH REQUEST" is displayed on the screen. 2. Select OK to change the working channel. 3. Select OK to return to the Home screen on the new channel. Position Tracking When you enable position tracking, your radio uses interval position-request calls to track up to three vessels. Regulations allow transmission of one position-request call every five minutes. You can call up to three vessels that your radio will alternate calling at five-minute intervals. If a vessel does not respond to five consecutive position-request calls, the vessel is removed from the position-tracking list. The following timetable shows the polling sequence when you have three vessels in the position-tracking list. The radio continues to send position-request calls until you stop position tracking by selecting EXIT.
