Altimeter Setup

The Altimeter Setup Page allows you to setup the Altimeter to self-
calibrate each time you turn on the unit, to function as a barometer or to
manually calibrate when you have accurate elevation or pressure data.
To set up the Altimeter:
1. Access the Altimeter Setup Page.
2. Highlight the "Auto Calibration" fi eld and press ENTER to
select from On or Off. When On, elevation is corrected by GPS.
3. Highlight the Barometer Mode fi eld and press ENTER to select
"Variable Elevation" (used when you are moving) or "Fixed
Elevation" (used when you are stationary. This allows the
Altimeter to function as a standard barometer). Elevation
trip data is not recorded when in the Fixed Elevation mode.

to display the Calibrate Altimeter Page. You can calibrate the
Altimeter using one of three methods:

graphic maps, scientifi c altimeters, etc. can be used.

for determining the accurate barometric pressure at your cur-
rent location. Scientifi c barometer, data from a weather station
