8. Troubleshooting

Frequently Asked Questions:

• Player fails to power on or charge:
  Reason: Using a fast charger (over 20W) may cause the player to enter protection mode, preventing it from powering on or charging.
  Solution: Charge the player with a standard 5V/1A charger for at least 20 minutes (or via a USB cable connected to a computer for 20 minutes). Then, press and hold the Volume "+" button and the Power button simultaneously for approximately 10-15 seconds until the screen lights up and enters forced recovery mode. Use the Volume "-" button to select "Factory Reset Mode", then press the Power button to confirm. The player will restart and return to normal. For subsequent charging, please use a 5V/1A charger or a USB cable connected to a computer.
• Player cannot be powered on after long-term non-use (when the battery is fully drained):
  Solution: Connect the charger to the device, and do not power it on immediately. Wait until the screen displays the charging indicator and the battery level reaches 5% or above before turning it on. Otherwise, the player may fail to start due to insufficient power.
