The watch will connect with the phone and perform auto time correction 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 correction is complete.
Q2Auto time correction is not performed at a scheduled time.

Note that auto time correction is not performed for 24 hours after swapping of the Home Time and World Time, or after the time setting is corrected manually on the watch. Auto time correction will resume 24 hours after either of the above operations is performed.

Time setting syncing will not be performed if you press (D) while a stopwatch elapsed time measurement operation or a timer countdown operation is in progress. Stop the current stopwatch or timer operation, and then press (D) again.
Q4Time is not displayed correctly.
If your phone is unable to receive a signal because you are outside its service range or for some other reason, the watch may not be able to display the correct time. If this happens, connect the phone to its network and then correct the time setting.
Step Count
Q1Displayed step count is not correct.
While the watch is on your wrist, it 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.
To avoid miscounting non-walking movements, the step count or distance value is not displayed for about 18 seconds after you start to walk.
It appears only after you have continued walking for about 18 seconds, with the number of steps you took during the first 18 seconds included in the total.
Q3[ERR] appears when counting steps.
[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.
Contact a CASIO service center or your original retailer.
