In ALTI & BARO mode you can view the current altitude or

barometric pressure. It offers three profiles: Automatic, Barometer

and Altimeter. For information on setting profiles, see

profiles

You can access different views depending on which profile is

activated when you are in ALTI & BARO mode.

Sunrise and sunset time views are available when GPS has been

activated. If GPS is not active, sunrise and sunset times are based on

the last recorded GPS data.

9.1 How Alti & Baro works

To get correct readings with

ALTI & BARO

mode, it is important to

understand how Suunto Ambit2 calculates altitude and sea level air

pressure. Suunto Ambit2 constantly measures absolute air pressure.

Based on this measurement and reference values, it calculates

altitude or sea level air pressure.

CAUTION: Keep the area around the sensor free of dirt and

sand. Never insert any objects into the sensor openings.
