- When Storm alert is ON, 30 second beep alert
will be given and “ ” will shown in Current
and World time mode when the watch predicts
the upcoming weather is stormy.
- Before calibrate the sea level pressure, consult
the nearest observatory to get the sea and air
pressure of your current position.
Important: Storm alert is triggered when pressure
drops quickly with a certain period of time. But
sometimes, a very fast pressure changes maybe
due to altitude changes. This pressure changes
due to altitude variation may result in exactly the
same pattern as storm altert false alarm may
occur.
Note:
- Input an incorrect pressure during the
adjustment procedure may results an incorrect
pressure reading in the future.
