1: for the first time, try to charge the headset for 2-4 hours. In the future, charge for 2 hours each time. Too long charging time will directly lead to aging or even burn out of the circuit board of the machine.

2: before putting the headset in the pocket or bag, turn off the headset first to avoid accidentally pressing the headset function key. Waste unnecessary power.

3: do not touch the earphone with sharp objects, which will cause scratches or damage; do not let any small objects into the earphone, which will damage the parts inside. So don't put it in your pocket after use. It's better to use a small bag alone.

4: do not expose the earphone to the liquid or damp place. It is better to clean the earphone surface with neutral solvent.

5: if the headset is not used for a long time, please make sure it is placed in a dry place. If it is placed for more than one month, it should be charged on time to ensure the working performance of the battery and headset, and it should be kept away from the place where the temperature changes greatly and is dusty.

6: do not put the earphone near the place where MRI is easy to form, such as the TV set or the magnet.

7: do not expose the earphone in the open fire to avoid explosion.

8: do not attempt to remove the headset by yourself.
