TROUBLE SHOOTING
Found
Make sure the antenna (on unit or exterior) is vertical and has a
clear view of the sky.
q
Check the initialization. The unit should be initialized within 300
miles of your position with the correct date and time in Universal
Time (UTC).
q
Wait 10 minutes and try again. Under some conditions, the unit
may not “see” satellites which are very close to the horizon.
More Satellites Needed
Check for satellite availability by pressing the AUX 1, Sat Status
key, and resetting any satellites you may have turned off with this
function.
Try 2D mode if three satellites are available, and if you know your
altitude.
Searching the Sky

For hand-held, battery operation, make sure the unit is free from
obstructions.
