requested.
If the VHF, despite being connected to a
GPS/position source, prompts for entering the
position and time information, the automated
update has most likely been lost either due to
missing data on the line, broken cabling or the
GPS/position source has failed. Refer to the
installation section in the back of this manual for
installation and connection details.
Until the automatic position update from
GPS/position source is restored position and time
must be entered manually when prompted by a (four
hour) timer in VHF.
In the DSC SETUP, Position Info, you can verity the
position data. If data is present Lat/Lon/UTC will be
displayed.
