How to set a new altitude reference value in Suunto Ambit3 Vertical?

The following steps apply for watches with software updates 1.1.22 or later.

To set a new reference altitude:

1. Keep NEXT pressed to enter the options menu.
2. Scroll to ALTITUDE with LIGHT and enter with NEXT. The following options are available:
   
   a. Auto adjust: With this option, the watch uses FusedAlti, where GPS and barometric altitude are combined to provide a more reliable altitude reading. Read more about FusedAlti in the user guide. We recommend using Auto adjust for setting the altitude reference value.
   
   Note: In good conditions, it takes several minutes for FusedAlti (Auto adjust) to activate. During that time, your watch shows your approximate altitude. Your altitude reading and altitude history while exercising will be corrected once your real altitude is defined via FusedAlti.
   
   b. Altitude: Set a known altitude manually. Use a topographic map or Google Earth to find the altitude of your current location.
