Thank you very much for your feedback on using the DB03 product. Your information is very important to us. If you encounter the fault you mentioned, you can try the following operations: 1. Check whether the safety key is stuck and whether other safety key functions can work normally; 2. Check whether the battery size is too large, which may cause internal structure deformation; 3. After confirming the above two points, you can try to turn off and restart the device.
