Correct Altitude Using Location (WF/TL/AC)
Operation
Each tap of this setting item toggles between “ON” and “OFF”.
Description
Select “ON” for this setting to perform auto altitude calibration based on the
watch’s or your smartphone’s location information (GPS). “OFF” must be
selected for this setting to perform altitude calibration manually using “Altitude
Calibration”.
Important!
●
When “ON” is selected for the “Correct Altitude Using Location” setting, the
correction operation is performed only when GPS reception is extremely
good. It is not performed in valleys, among buildings, or in any other location
where reception is poor.
●
Even if correction is being performed, it is based on the GPS measurement
value. Because of this, resulting altitudes may not necessarily match the
actual altitude or elevation above sea level values. The effect of geoid
elevation may result in post-correction altitude values that include error. In
Japan, included error is approximately 40 meters.
●
If you want more accurate altitude readings, turning off this item and
performing the “Altitude Calibration” operation by manually inputting locally
indicated altitude values is recommended.
