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 P�GE 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. Hold the GPSMAP 76CSx level to get an
accurate electronic compass reading.

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.
