[dot_ArrowMark ERR] will appear on the display if a direction sensor error occurs while Location Indicator is in use.

Auto Altitude Calibration

Enabling auto altitude calibration with CASIO WATCHES will cause altitude values to be acquired by CASIO WATCHES, which will be used to automatically correct the watch’s altitude reading.

Important!

Use CASIO WATCHES to enable or disable auto altitude calibration. It cannot be enabled or disabled on the watch.

Note

If an altitude value acquired by CASIO WATCHES satisfies accuracy conditions, the watch will automatically correct is altitude reading.

Auto altitude calibration is performed at the same time as auto time correction.

Auto altitude calibration is not performed for 12 hours after the time setting is adjusted manually.
