6. Troubleshooting

If you encounter issues with your PECSU S2 MP3 Player, refer to the following common solutions:

Problem	Possible Cause	Solution
Device does not power on.	Battery is depleted.	Charge the device for at least 15 minutes before attempting to power on.
Cannot transfer files to the player.	Improper USB connection; computer not recognizing device.	Ensure the USB cable is securely connected. Try a different USB port or cable. Restart both the player and your computer. Ensure the device is not in another mode (e.g., charging only).
Bluetooth device not pairing.	Bluetooth on player or external device is off; device not in pairing mode.	Ensure Bluetooth is enabled on both devices. Put the external device into pairing mode. Move devices closer together.
FM Radio has static or no signal.	Wired headphones not connected; poor signal area.	Connect wired headphones, as they act as the antenna. Move to an area with better reception.
Navigation buttons are confusing.	Unfamiliarity with interface design.	Familiarize yourself with the button functions. Note that 'Previous' and 'Next' buttons may control vertical scrolling in menus.
No ID3 tag information or album art displayed during music playback.	Device limitation.	The PECSU S2 player displays file names during playback and does not support ID3 tag or album art display. This is expected behavior.

If the problem persists after trying these solutions, please contact PECSU customer support.
