Q6,When the wristband fails to be searched by mobile phone

Make sure the wristband still has power and in activated state without connections to other phones. Put the wristband near mobile phone, if it is still ineffective, turned off BT on mobile phone and turned it on again at intervals of about 20 seconds.

Q7,Shall BT be turned on all the time ? Are there data if it is turned off ?

Prior to data synchronization, the exercise and sleep data will be reserved on the wristband host. When mobile phone and wristband BT 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.

Notice: lf the incoming call and short message reminders are

activated, BT 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.

1). Confirm the host insertion direction.

2). When the host battery is lower than 3.6V there will be some

period of battery pre-charging.

Q10,If the wristband is worn all the time, will BT radiation damage human body?

The wristband BT radiation is far below the FCC

standard and can be ignored basically, long time wearing will not cause radiation injury.
