frequently, preferably before starting your journey when the reference values

9.1.2 Getting incorrect readings
ALTIMETER profile + standing still + weather change
If your Altimeter profile is on for an extended period of time with the device
in a fixed location while the local weather changes, the device will give incorrect
altitude readings.
ALTIMETER profile + altitude moving + weather change
If your Altimeter profile is on and the weather changes frequently while you
climb in altitude or go down in altitude, the device will give you incorrect
readings.
BAROMETER profile + altitude moving
If the Barometer profile is on for an extended period of time as you climb in
altitude or go down in altitude, the device assumes that you are standing still
and interprets your changes in altitude as changes in sea level air pressure. It
will therefore give you incorrect sea level air pressure readings.
Use example: Setting the 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
moving in the morning.You know that the current altitude readings given by
your Suunto Ambit2 are wrong. So, you hike to the nearest location shown on
