You can reset your S1 by using a needle to press the Reset button next to the charging port. The reset will be complete when the screen briefly lights up. You can watch this video: ProTemp S1 Reset

We suggest that you use the charging cable in the packaging for charging. Other charging cables may not be compatible, and please note that your charging head power should not exceed 20W. And please use a 5V/2A DC adapter for charging, and do not use an AC adapter. Otherwise, it may cause damage.

If the problem cannot be solved, please shoot a video of the issue and send it to [email protected] for confirmation.
