Operating Instructions
1. Basic Music Playback
After transferring music, navigate to the "Music" interface. You can browse by "All Songs," "Local folder," "Card folder," "Artists," or "Albums." Select a song to begin playback. The device requires wired headphones for audio output as it does not have a built-in speaker.

To repeat a specific segment of a song, enter "Repeat Mode" from the playback options. The letter "A" will blink. Press the Right button to set the starting point. Then, "B" will blink; press the Right button again to set the endpoint. The segment "A-B" will turn red, indicating the repeat segment is set. Press the Right button again to cancel the repeat and resume normal playback.

The "Variable Speed Playback" option allows you to adjust the playback speed of your audio files. You can choose speeds ranging from -8 to +8 for different listening rates.

Use the "Volume Limit" setting to set a maximum adjustable volume for your music. This can help protect your hearing or manage audio output in certain environments. You can also adjust the volume directly using the dedicated volume keys on the side of the player.
8. FM Radio
To use the FM Radio function, you must connect wired headphones, as they act as the antenna. Navigate to the "FM Radio" option from the main menu. You can then scan for stations and listen to broadcasts.
