Precautions for invisible headphones

When the wireless contact earphone is not used for a long time, please take out the battery;

The battery must use a special charger when charging the wireless contact earphone;

Connect the computer and mobile phone with data cable, and send information with mobile phone software. You can edit and send long messages through the computer. When actually sending, the mobile phone will be divided into multiple messages. However, due to network transmission, the order of receiving multiple short messages may be different.

Use China Mobile's Fetion function to send short messages, but be careful not to enter nicknames when registering online, or you will add nicknames at the beginning of the received short messages, which will lead to unsuccessful setup and learning. When the number of characters entered exceeds one short message (70 Chinese characters or English letters on 140), Fetion will automatically add the words (1/2) or (1/3) at the beginning of the short message.

Note: every time the SMS repeater receives a SMS, it will automatically send a SMS confirmation to the sending mobile phone, and the memory function will not be affected by power failure. Be sure to pay attention during use: plug the microphone output plug into the mic port of the computer, and you can have wireless voice chat within two meters of the microphone. The volume of computer, TV and DVD affects the volume and sound quality of receiving headphones.
