Precautions for use:
1. Be sure to plug in the position when charging. The force should be as light as possible when plugging and unplugging, otherwise the plug will be loose after a long time.
2. Use the paired charger. If there is a dedicated charger, use a special one. If it is not equipped, you can use the 500MA-1000MA charger, preferably not more than 1000MA.
3. Generally charge for about 2 hours, try not to exceed 3 hours. If it is long, it will only cause fever and is not good for the battery.
4. Don't always charge the battery when it is completely turned off, so it is not very good for the battery, headphones, and the signal when it is used last.
5. It is not recommended to use headphones when charging, so as not to cause unnecessary accidental damage.
6. When charging, the general red indicator light is on, indicating that when the charging is in progress, when the light turns blue or other colors, the charging is completed.
7. If there is no power after using it for a while, it may be a problem with the battery or circuit. It is best not to continue charging it.
