Alti/Baro Mode; Alti Use - Suunto X9i Guia Del Usuario

5. ALTI/BARO MODE

The Alti/Baro mode is used for measuring altitude, barometric pressure and
temperature. Suunto X9i calculates the altitude from the current barometric pressure,
which is more sensitive and accurate than the altitude measurement with the GPS,
and is also available when the GPS is off.
Because both altitude and weather data are measured with the same barometric
sensor, you have to select whether you want to use this mode as an altimeter or as a
weather station. The Use selection defines the set of information shown on the main
display. The Alti/Baro menu also contains weather and altitude alarms, the reference
setting needed to relate the current weather state with your current altitude, and the
weather memory.
