Correct Altitude Using Location (WF/TL/AC/EX)
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. Since GPS information generally includes some
error, there may be error in relation to actual altitudes indicated locally. 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.

Description
Though the pressure sensor built into the watch is adjusted at the factory and
normally does not require calibration, you can perform the calibration
operation above if you notice that readings are very different from those from
other sources. To calibrate manually, use this item to input the current
barometric pressure as measured by another accurate barometer.
