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, 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 unit it is discharged, 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 your amplifier(BTR3/BTR5) could be turned on still, please go to FiiO Control and check whether the charge option has been set to 'OFF'.
If the issue still remains, please contact us again with the receipt attached. Thanks in advanced.
We apologize for any inconvenience in the meantime!
