About the Altitude Alarm

The altitude alarm sounds for about five seconds when the current altitude matches a preset value during an altitude measurement operation. You can press any button to stop the alarm after it starts to sound.

The altitude alarm sounds only while the Altimeter Mode’s Altitude Screen is on the display. It does not sound while the watch is in another mode or while another Altimeter Mode screen is on the display.

Example

If you set the altitude alarm at 130 meters, it sounds when you pass the 130- meter mark on your way up and on your way back down.
