Receiving Position Requests
You can configure the radio to reply automatically to incoming position requests, or prompt you to review and
approve the incoming requests before replying (
Sending Automatic Replies, page 19
).
When you receive a position request with automatic position replies enabled, SENDING ACKNOWLEDGE
appears on the screen, and the radio sends your position automatically. After the position successfully
transmits, POSITION SENT appears on the screen.
When you receive a position request with automatic position replies disabled, POS. REQUEST appears on the
screen.
When you receive a position request with automatic position replies disabled, select OK, and select an
option:
• To reply to the position request with your current position, select OK.
If GPS-position or manual-position data is available, the radio transmits your position to the other vessel.
• To ignore the position request, press CLEAR.
Receiving Position Calls
When you receive a position call, POS. SEND and the position data appear on the screen.
Select OK.
The radio saves the position report in the call log.
Receiving Group Calls
When you receive a group call, GROUP appears on the screen, and the radio prompts you to change to the
requested channel. If the channel requested is invalid, INVALID CH REQUEST appears on the screen.
1 Select OK.
2 Turn the ENTER dial to select the requested channel.
3 Select OK.
Position Tracking
When you enable position tracking, the radio uses interval-based position requests to track up to three vessels.
Your radio transmits received position data over the NMEA network, and you can track the vessels using your
Garmin chartplotter (
Configuring DSC NMEA Transmissions, page 21
).
Selecting Vessels and Activating Position Tracking
Before you can use position tracking, you must have at least one vessel saved in the directory (
).
1 Select DSC > POS. TRACKING > ADD ENTRY.
2 Select the vessels you want to track.
You can track the position of up to three vessels at one time. If you select a fourth vessel, the radio sounds
an error tone, and you must remove a vessel before you can add a new one.
3 Select BEGIN TRACKING.
