The GPS 12 will now begin searching for the
appropriate satellites for your location and should
acquire a position in under three minutes. You can ver-
ify that you have acquired a position by watching the
Satellite Page transition to the Position Page (provided
you haven’t pressed any other buttons) or by looking
for a ‘2D NAV’ or ‘3DNAV’ status at the top-left corner
of the Satellite Page.
Initialization Troubleshooting
If you have trouble initializing the receiver or
acquiring a position, check the following:
•Does the unit have a clear view of the sky?
If there are large buildings or mountains nearby, or
if there is heavy tree cover, the receiver may not be
receiving enough satellite signals to calculate a
position.
•Have you selected the right country/state/region
from the EZinit list?
Check for the correct approximate lat/lon on the
Position Page, or reselect the appropriate country
from the list to restart the initialization.
•Have you moved more than 500 miles from the
last calculated position with the receiver off?
Reinitialize the receiver, selecting the country/state/
region of your new location from the EZinitlist.
Your unit should now be initialized.
