Then . . .
The antenna may be partially shaded by metallic objects
around it. Re-position or raise the antenna away from the
object for a better satellite view.
Signals may be lost when the antenna is under a bridge or
when shielded by buildings.
Check the quality of the antenna location—the antenna
should have a clear view of the sky. For the correct antenna
placement, see Figure 7 on page 14.
Make sure the antenna is clean, and not covered with ice,
snow, or exhaust soot.
Check that WAAS is available in your operating area.
Reset the 972's satellite elevation setting to its default (5
degrees).
NOTE: Please have the 972's serial number — available on the back of
the unit or on the Options/Service Info screen — ready before
contacting Northstar's Service Department. For help with
software questions, please have your software version number
available (press the
Options/Service Info screen).
