Acquiring Satellites
The GPSCOM 170 will now begin searching for the
appropriate satellites for your position and should
acquire a fix within three to five minutes. You can verify
getting a position fix by watching the status page transi-
tion to the position page (provided you haven’t pressed
any other keys) or by looking for a ‘2D NAV’ or ‘3D NAV’
status at the top-left corner of the status page.
Troubleshooting
If you have trouble initializing the receiver or getting
a position fix, check the following:
• Does the antenna have a clear view of the sky?
If there are large buildings such as hangers, metal sur-
faces, or other obstructions, the unit may not be
receiving enough satellite signals to calculate a fix.
• Is the right country/state selected 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 of
your new location from the EZinit list.

APPENDIX A
Once satellites have been
found, hollow signal
strength bars will be dis-
played while the data is
being collected. The signal
strength bars can be used to
help determine if satellites
are being shaded.
