- In Barometer mode, press and hold [M] to enter 

setting mode. Press [M] to select among the 
settings. 

- 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.

- Motors,
- Mobile phones and etc.
Avoid measuring direction when:
- Close to a magnetic object
- Close to metallic object
- Close to an electrical appliance
- Inside a moving object.

Perform compass calibration or magnetic 

declination compensation process when:

- The Watch is using for the first time, 
- The battery has been replaced,
- The bearing direction digits are flashing, and 

the compass bearing and compass 
direction are flashing

- The compass uses in a location that is apart

from the place in which the compass had
