Calibrating the Electronic Compass
When you first use the GPSMAP 76CSx or after
you install new batteries, you have to calibrate the
electronic compass outdoors. The accuracy of the
electronic compass is adversely affected if the unit
is not held level or you are near objects that generate
magnetic fields, such as cars or buildings.
