2. Select START TRACK, then select YES. The START TRACK display changes to STOP TRACK. To stop tracking
at any time, just select YES.
As soon as you start tracking, an LL Request is sent immediately on CH70 and your radio waits for
acknowledgement of the (first) buddy’s LL position to be displayed on your LCD.
Each of the selected buddies is polled for their LL positions at regular time intervals. When information
is received, a friendly ringtone is sounded and the position is shown on the LCD. Press any key to cancel
the display.
An LL position that is received is not stored in your radio’s log, but is broadcast over NAVBUS to the
chartplotters. Press any key to acknowledge or wait for the automatic 20 second time out.
NOTE: The Explorer 721/725 can receive and display the LL position data at normal or enhanced resolution.
