13. What to do if my BTR5 2021 cannot be turned on or charged?

If the device cannot be turned on or charged, it is suggested to follow the tips below to solve it.

1. Try other power adapters and cables.
2. The battery of your device may be overused, so it needs to be refreshed through low-current power. Please try to charge the product using the computer for about 30mins, and then hold the power button for 30s to force a restart.
3. If the above 2 measures cannot help, you can try to leave the device aside for 2 to 3 days, and then charge it again. Because sometimes its system may be stuck, it would return to normal when the device runs out of power.
4. If the device can be turned on still, please go to the FiiO Control App to check whether the charging option is set to 'ON'.
5. If the issue still remains, please send an email to support@fiio.com for help.
