The charging time of the microphone is too short, less than 30 minutes or more (the charging time can be at least 30 minutes or more before normal startup, and the full charging time is about 3 hours or so);

3, the microphone charging circuit fault (if the above two methods of testing, the microphone still can not work normally, replace the microphone after the fault is eliminated, it means that the microphone charging circuit fault).
The general model can be standby for 4 ~ 6 hours, the new microphone?? Time will eat a little more.
