Description:

1) Compatible with MP3 format, featuring automatic power-on and a red LED indicator for playback status updates.

2) Supports U disk (tested with 32G) and TF Card (tested with 16G) play modes; defaults to TF card mode upon power-on. If no TF card is present, it automatically switches to U disk. Users can manually set playback modes by referring to the key operating instructions.

3) The keys allow for track up/down switching, volume control (+ and -), pause/play, and mode selection. For detailed instructions, please consult the key operating manual.

4) The player can be configured to play single or all songs. By default, it powers up in whole song cycle mode, which can be changed to repeating mode by pressing the "Repeat" key.

Key operating instructions:

- The "Prev/V--" key: A short press switches to the previous song, while a long press decreases volume.

- The "Next++" key: A short press advances to the next song, and a long press increases volume.

- The "P/P/Mode" key: A short press toggles play/pause, and a long press selects between U disk and TF Card modes.

- The "Repeat" key: A short press cycles through single/song repeat modes; no function when not pressed.

Note:

1. The "long press" duration is approximately 2 seconds.

2. When using U disk mode, it is recommended to use a 5V power supply, as some U disks may not support 3.7V power supply.
