Function Description

• Power up，If MCU and sensor connection are unnormal，then the corresponding error will display.
• If the Chronograph IC and MCU connection are unnormal，dot-matrix display“ERR1”
• If the Compass IC and MCU connection are unnormal，dot-matrix display“ERR2”
• The above unnormal status only displays for 2s，and then it will reenter the time mode.If the connection is normal, then no error will display，directly return to the time mode.

11、Comprehensive explanation

1. When setting the magnetic declination，When set to +，The display angle is the measured angle plus the correction angle，When set to negative,The display angle is the actual angle minus the correction angle.
2. Pedometer dormancy. When pedometer is on，without step calculation or stop for one minute，The pedometer function will go to the dormant state to save power，after swing or walking it will exit the dormant state.
3. Compass test. test once each 250ms，choose the average value of the two most recent values
4. Low-voltage detection. Test once per hour,Low power is detected at 59 minutes 55 seconds
