Main Pages Using the Electronic Compass When you press and hold PAGE on these units, the electronic compass turns off and stays off until you press and hold PAGE again. The electronic compass functions like a magnetic compass when you are stationary. When you are moving and reach a pre-set speed, it uses data from the GPS receiver to maintain your heading. When you stop (after a pre-set time), it again operates like a magnetic compass. To turn the electronic compass on or off: 1. Press and hold the PAGE key to turn the electronic compass on or off. The Compass icon appears in the status bar when the electronic compass is on. When you are not using the electronic compass, turn it off to conserve batteries. When it is turned off, the unit uses the GPS receiver for navigation. 2.

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.
