9 USING ALTI & BARO MODE

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 Section 9.2.1 Setting profiles on page 54.

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.
