If you cannot turn off by holding down the power button, you can perform a reset operation:
1. Prepare a thin needle, toothpick, or paper clip.
2. Find the RESET hole next to the charging port of S1 Main Unit.
3. Insert the fine needle into the RESET hole and gently press until the screen briefly disappears and lights up to indicate that the reset is complete.
If it still cannot be resolved, please contact our customer service email [email protected] Please provide your order number and instructional video. We will provide further diagnosis and support.
