CALIBRATE ALTIMETER
Because the Geko 301 relies on the Barometric pressure to determine the elevation and
the pressure at any given elevation can fl uctuate, you can calibrate the altimeter to improve
its accuracy. You must know the elevation at your current location, information you can
obtain from a map or other reliable source.
To manually calibrate the altimeter:
1. Press the PAGE Button to access the Main Menu.
2. Press the UP or DOWN Button to highlight the ‘CALIBRATE’ option and press the OK
Button. Select the ‘ALTIMETER’ option.
3. At the message stating “DO YOU KNOW THE CORRECT ELEVATION?” highlight the on-
screen ‘YES’ button and press the OK Button
.
4. Use the UP, DOWN, and OK Buttons to enter the new elevation, then highlight the on-
screen ‘OK’ and press the OK Button to select the elevation and return to the Elevation Page.
NOTE: The best altimeter calibration to use is ‘known altitude’. If you know your Barometric
pressure of the area you reside in, you do have the option to calibrate by ‘known pressure’.
