Calibrating the Altimeter
Because the altimeter relies
on the barometric pressure to
determine the elevation and the
pressure at any given elevation
can fluctuate, calibrate the
altimeter to increase its accuracy.
To manually calibrate the
altimeter:
1. Press MENU > Calibrate
Altimeter .
2. At the message “Do You Know
The Correct Elevation?” select
Yes . If you do not know the
elevation, select No to use
the pressure option. If you do
not know the pressure, select
No to use the default GPS
elevation.
3. Use the ROCKER > OK to
enter the new elevation or
pressure.
