SUUNTO LUMI - Manual (Page 24)

Handy tip: Setting altitude reference value
You’re on the second day of your two-day hike. You realize that you forgot to switch
from the
BAROMETER profile to the ALTIMETER profile when you started out in the
morning. So you hike to the nearest location shown on your topographic map for
which a reference altitude value is provided. You set your Suunto Lumi altitude
reference value accordingly. Your altitude readings are correct again.

6.2.1 Setting altitude reference value
It is really important to provide an accurate altitude reference value. The altitude
reference is the exact altitude of where you are currently standing. You can
find this measurement from any topographic map. The more often you insert
an altitude reference value, the more precise the current reading will be as the
air pressure usually changes depending on your location. Your Suunto Lumi
will remind you to set the altitude reference value, if needed!
You can set your altitude reference value in MENU . To enter MENU , press [Mode]
for 2 seconds - the menu icon in the upper right corner will blink twice.
