Prior to data synchronization, the exercise and sleep data will be reserved on the wristband host. When mobile phone and wristband Bluetooth connection is successful, data of the wristband will be automatically uploaded to the phone. But when the data storage space for about one week on wristband is full, the system will circulate covering the earliest data; please synchronize data onto the wristband in time.

activated, Bluetooth must be kept in connection. Alarm clock

supports offline reminder.

As everyone's physical mechanism varies, calorie and data consumed in exercise are also different. Users shall set personal information before synchronization to wristband prior to exercise data checking.

period of battery pre-charging.
