It is important that the local time, date
and initial position are approximately
correct in order for the Receiver to
quickly locate and track satellites.
Check that the Local Time is ap-
proximately correct. This will be
updated every time GPS satellites are
tracked. Check also the Time Zone
for your current location and Local
Date.
Then check your local position. If you

The NAV (F6) key enables you to
activate or deactivate the navigated
height solution. For most applications
this will be deactivated as it enables a
navigated position calculation with
only 3 satellites.
Certain aerial applications may need
to switch this to NO, thereby activat-
ing the navigated height solution.
