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. On the Settings Menu, select Altimeter.
2. Select the Auto Calibration eld > ENTER to select
from On or Off. When On, elevation is corrected by
the GPS receiver.
3. Select the Barometer Mode eld > to select Variable
Elevation (used when moving) or Fixed Elevation
(used when stationary, allowing the altimeter to
function as a standard barometer). Trip data is not
recorded when in Fixed Elevation mode.
To manually calibrate the altimeter:
1. Select the Calibrate Altimeter button >. Calibrate the
altimeter using one of three methods:
Enter the correct elevation: this requires a reliable
source for determining the elevation for your
current location.
Enter the correct pressure: this requires a reliable
source to determine the accurate barometric
pressure at your current location.
Allow the GPS Receiver to determine the
elevation.
2. When nished, a “Completed” or “Failed“ message
appears.
