Auto Time Adjustment by Bluetooth Connection (Time Adjustment)

The watch will connect with the phone and perform auto time adjustment at around 12:30 a.m., 6:30 a.m., 12:30 p.m. and 6:30 p.m. The connection is automatically terminated after auto time adjustment is complete.

Did you recently swap your Home Time and World Time, or manually adjust the watch’s time setting?
Note that auto time adjustment is not performed for 24 hours after swapping of the Home Time and World Time, or after the time setting is adjusted manually on the watch. Auto time adjustment will resume 24 hours after either of the above operations is performed.
Is auto time adjustment enabled?
Auto time adjustment will not be performed at the scheduled times unless it is enabled. Enable auto time adjustment.
Q3Time is not displayed correctly.
The phone’s time setting may be incorrect because it is unable to connect with its network due to being out of range, etc. If this happens, connect the phone to its network and then adjust the time setting.
Pedometer
Q1Displayed step count is not correct.
While the watch is on your wrist, the pedometer may detect non-step movements and count them as steps.
Also, step count problems can also be caused by how the watch is being worn and abnormal arm movement while walking.
Q2The step count does not increase.
The step count is not displayed at the beginning of a walk in order to avoid miscounting of non-walking movements.
It appears only after you have continued walking for about 10 seconds, with the number of steps you took during the first 10 seconds included in to the total.
Q3[ERR] appears when using the pedometer.
[ERR] (error) indicates that sensor operation is disabled because of sensor or internal circuitry malfunction.
If the indicator remains on the display for more than three minutes or if it frequently appears, it could indicate a faulty sensor.
Alarm

Is the alarm setting turned on? If it isn’t, turn it on so it will sound.

Q2All hands are stopped and buttons do not work.

Q3The hands suddenly start moving at high speed.
This is due to one of the reasons below, and does not indicate malfunction. Simply wait until normal hand movement resumes.

Battery
Q1
