If your helmet is turning off without reason, there are a few things you can try to troubleshoot the issue:

1. Check the battery level: If the battery is low, the helmet may turn off unexpectedly. Make sure the battery is fully charged before using the helmet.

2. Perform a factory reset: Connect the charger to the helmet and perform a factory reset by pressing and holding the power button for 20 seconds. This will reset the helmet's settings to their default values and may resolve any software issues causing the helmet to turn off.

3. Contact customer support: If none of the above steps resolve the issue, please contact our customer support team for further assistance. We may need to inspect the helmet or provide a replacement if it is found to be defective.

We hope these tips help resolve the issue with your helmet turning off without reason. If you have any further questions or concerns, please don't hesitate to reach out to our customer support team.
