Storm alarm
A significant drop in barometric pressure typically means a storm is
coming and you should take cover. When the storm alarm is active,
Suunto Traversesounds an alarm and flashes a storm symbol when the
pressure drops 4 hPa (0.12 inHg) or more during a 3-hour period.
NOTE: The storm alarm does not work if you have altimeter profile
activated. See 3.2.2 Matching profile to activity.
To activate Storm alarm:
1. Keep [Next] pressed to enter the options menu.
2. Scroll to ALTI-BARO with [Light] and enter with [Next].
3. Press [Next] to select Storm alarm.
4. Set the storm alarm On or Off with [Start] or [Light] and accept
with [Next].
When a storm alarm sounds, pressing any button ends the alarm. If no
button is pressed, the alarm repeats once after five minutes. The storm
symbol remains on the display until the weather conditions stabilize
(pressure drop slows down).
