The Electronic Compass
When you manually turn the Compass Off, it stays off until you
manually turn it On again. Sometimes, however, when you turn the
Compass On, the GPSmap 76CS overrides the Compass and uses the GPS
receiver to track your heading. The criteria for switching between the
Compass and the GPS can be customized. (See below.)
Turning the Electronic Compass On and Off:
1. Press and hold the

2. Hold the GPSmap 76CS level to get an accurate Electronic
Compass reading. A "Hold Level" reminder displays if you are
