Calibrating the Electronic Compass
Calibrate the electronic compass outdoors when you
first use the GPSMAP 76CSx. To ensure continued
accuracy, calibrate after installing new batteries,
after moving more than 100 miles (160 km), or
experiencing a temperature change greater than
68º F (20º C) from the last calibration. The accuracy
of the electronic compass is also adversely affected if
the unit is not held level or you are near objects that
affect magnetic fields, such as cars or buildings.
