As soon as you start tracking, an LL Request is sent immediately on CH70 and your radio; and
it waits for acknowledgement of the (first) buddy’s LL position to be displayed on your radio
screen.
Each of the selected buddies is polled for their LL positions at regular time intervals.
When information is received, a friendly ring tone sounds and the position is shown on the
screen. Pressing any key cancels the screen.
The 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 timeout.
Note: The LHR-80 is capable of receiving and displaying the LL position data at normal or
enhanced resolution.

The DSC icon on the screen flashes and the call alert sounds when the radio receives
an ALL SHIPS call from another boat or a coast station within range. A call alert with a
friendly two-tone cycle indicates a ROUTINE call.
A call alert with a cycle of 6 beeps followed by a 2 second pause indicates an URGENCY
or DISTRESS call.
Press any button to cancel the call alert. The radio is switched to the designated channel
by pressing ENTER, or return to the old channel by pressing ESC. The priority level and
the user MMSI are shown on the screen. If the radio recognizes the user MMSI as one of
your buddies, the buddy name is shown in place of the user MMSI.
Press PTT to initiate voice contact on CH16 and then switch to a working channel; OR
press ESC if you do not want to make voice contact. The call data is stored in your call log.
