Contrast Adjustment
To turn the NavTalk on and off:
Each time the Navtalk is turned on, the Welcome
Page will appear while the unit conducts a self test.
Once the internal test is complete (after a few seconds),
the Land Data Warning Page will appear, asking you to
read and acknowledge important information regarding
the proper use of the land data that is provided.
After approximately ten seconds, the Land Data
Warning Page will be replaced by the Cellular Status
Page. Press the
these pages. (If the Satellite Status Page appears instead of
the Cellular Status Page, it's because the unit was in the
GPS receiver mode when it was turned off.)
At this point you may want to adjust the screen
contrast which can be done by first selecting the GPS
mode Satellite Status Page or Cellular Mode Status Page.
Contrast adjustment is also available from the
Setup Menu/System Page.
The Zoom/Volume keys can be used to adjust the
ringer, beeper, and speaker volume on any page (other
than the GPS map and highway pages). Pressing these
keys will cause a pop-up menu to appear, showing slid-
ing indicators for each volume control. Each field must
be selected prior to changing volume settings.
