Calibrating the
Electronic Compass
Calibrate the electronic compass
outdoors when you first use the
Vista H. 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.
To calibrate the electronic
compass (Vista H only):
1. While outdoors, hold the Vista
H level and do not stand
near objects that influence
magnetic fields, such as cars,
buildings, or overhead power
lines.
2. Press MENU > Calibration .
