In the Alarms menu of your watch, under Settings you can set different adaptive alarm types.
You can set an alarm for sunrise and sunset and also for storm alarm.
For dive alarm settings, see Dive alarms and Freedive alarms.
The sunrise/sunset alarms in your Suunto Ocean are adaptive alarms based on your location. Instead of setting a fixed time, you set the alarm for how much in advance you want to be alerted before the actual sunrise or sunset.
The sunrise and sunset times are determined via GPS, so your watch relies on the GPS data from the last time you used GPS.
To set sunset/sunrise alarms:
Scroll to the alarm that you want to set and select by pressing the middle button.
Set the desired hours and minutes prior to sunrise/sunset by scrolling up/down with the upper and lower buttons and confirming with the middle button.
A watch face is also available that shows sunrise and sunset times.
Sunrise and sunset times and alarms require a GPS fix. The times are blank until GPS data is available.
A significant drop in barometric pressure typically means a storm is coming and you should take cover. When the storm alarm is active, Suunto Ocean sounds an alarm and displays a storm symbol when the pressure drops 4 hPa (0.12 inHg) or more during a 3-hour period.
To activate the storm alarm:
When a storm alarm sounds, pressing any button ends the alarm. If no button is pressed, the alarm notification lasts for one minute. The storm symbol remains on the display until the weather conditions stabilize (pressure drop slows down).
