3.3.7. Alarm
With the Alarm function you can define two different alarms;
altitude alarm and weather alarm. When you have set an
alarm, its symbol appears on the display.
Weather Alarm
Suunto X9i checks the barometric pressure every 15 minutes.
The Baro Al function informs you when the barometric
pressure changes more than 4 hPa (0.118 inHg) in 3 hours.
This is a typically used metheorological value for rapid
weather change.
When the GPS is on, the weather alarm is able to detect
weather changes even when the altitude is changing.
