satellites for calculating
the horizontal position.
Elevation data is not
provided, and the position
error may be signicant.

reception. The GPS
receiver has enough

Synchronization
In the top right corner of the
screen you have another button
that leads to a new screen
where you can synchronize
the clock of your PNA to the
accurate time provided by the
connected GPS.
Turn on the Auto Correction
switch to let this Navigator
frequently check and correct the
PNA time with the GPS time.
Below that button you will
see the current values of the
GPS and the PNA clocks.
You can check here whether
any correction is needed. Tap
the button to manually
synchronize the time.
Below the PNA time you have
and controls to
manually correct the time with or
without a valid GPS time. It also
gives you the chance to correct
the time after synchronization if
your PNA does not support time
zones or daylight savings time.
