Calibrating Altitude Readings

There are two settings for calibrating altitude readings: “Altitude Calibration” and “Correct Altitude Using Location” (when connected to an Android smartphone only).


Altitude Calibration	You can lessen error in the altitude readings displayed by the watch by manually inputting accurate local altitude and elevation values. You can find out the elevation at your current location from signs, maps, on the Internet, etc. While mountain climbing, it is highly recommended that you make a habit of regularly comparing altitude readings produced by the watch with locally available elevation indications, and of performing this procedure as required.
Correct Altitude Using Location	Select “ON” for this setting to have altitude readings corrected automatically in accordance with your smartphone’s GPS information. “OFF” must be selected for this setting to perform altitude calibration manually.
