If you are operating with the Battery Saver on, the unit shuts itself off
if it cannot locate enough satellites for a fix. Check Sat(ellite) Status
with AUX 3 to be sure that no satellites have been set to "OFF."
This message appears when
the unit is set to 3D
operation, and not enough
satellites are available for a
3D fix. Try 2D, which
requires fewer satellites.
Unit Searches Constantly
If the unit has an Almanac and is unable to locate satellites, it searches
continually until a satellite is found.
Search and Acquisition Errors
Under the following conditions, the unit may be unable to obtain a
position fix:
o Initialization was not done correctly.
o
Poor signal environment.
o Insufficient number of satellites.
o Unit searches constantly.
Insufficient Number of Satellites
The NAV 5000 checks its Almanac before beginning to search for
satellites. The receiver will not turn on if the Almanac indicates that not
enough satellites are within view to establish a position fix.
This message appears
when the Almanac indi-
cates that not enough
satellites are in view to
take a fix. The receiver
remains off.
