Suunto X6 User Manual page 29

Select the correct use according to what you want to measure. For example, on a
hiking trip, you can select Alti for the day to see how high you have climbed. When
you camp for the night, you can change the use to Baro to make sure that the weather
changes do not catch you by surprise.
To select either Altimeter or Barometer use:
1. In the Function menu, scroll to Use with the arrow buttons and press Suunto. The
Alti/Baro field is activated.
2. Change the content of the field with the arrow buttons and press Suunto. You then
return to the Function menu.
3.3.3. Altitude/Sealevel
In order for the altimeter to function correctly you need to set the reference altitude.
This means that you set an altitude reading that is equal to the real altitude. Set the
reference altitude in a place where you know the altitude, for example, with the help
of a topographical map. The Suunto X6/X6M has a factory set reference altitude that
corresponds to the standard barometric pressure (1013hPa/29.90inHg) at sea level.
If you do not know your current altitude or the correct sea level pressure, you can
have an estimate of your altitude by setting the sea level pressure to 1013 hPa/29.90
inHg.
In the Weather mode, Altitude is replaced with Sealevel, this functions and is set in the
same way as Altitude.
To set the reference altitude:
1. In the Function menu, scroll to Altitude with the arrow buttons and press Suunto.
2. With the arrow buttons, set the reference altitude in the field to match the altitude of
you current location and press Suunto. You return to the Function menu.
