Instructions:
1. Before use, please confirm that the battery pack is fully charged;
2. When the ear clamp is not in use, please ensure that the power cord and power supply of the ear clamp are disconnected (especially remember: when installing the ear tag and ear pin, the fingers holding the clamp should leave the machine to avoid pressing them);
3. After replacing different ear needles, they need to be tested before use. If marking is not possible, a gasket can be added to the thread of the ear needle.
