Recording Functions

The MP3 player supports three types of recording:

• Line-In Record: Connect the MP3 player to a computer/phone via an audio line (3.5mm AUX cable). Play audio on the source device and start recording on the MP3 player to capture the sound.
• FM Radio Record: Record FM radio programs directly from the player.
• Voice Record: Use the built-in microphone to record voice memos. Long press the Record/Vol- button to initiate voice recording.

Other Functions

• E-book: Read text files (TXT format).
• Picture Viewer: View image files.
• Alarm Clock: Set alarms.
• Sleep Timer: Found in "Settings" under "Shutdown Setting". Set a time (max 99 minutes) after which the player will automatically turn off. This is useful for listening before sleep.
• Auto Off: Also in "Shutdown Setting". This feature turns off the player after a set period (e.g., 3, 10, or 30 minutes) of no operation to save power. If using Sleep Timer, it is recommended to disable Auto Off or set it to the longest duration (30 minutes).

Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Avoid liquid cleaners or abrasive materials.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge the device regularly. Store in a cool, dry place if not used for extended periods.
• Storage: Keep the device away from extreme temperatures, direct sunlight, dust, and moisture.

Troubleshooting

Problem: FM radio does not work.

Solution: Ensure wired headphones are connected. They serve as the antenna for the FM radio, regardless of whether you are using Bluetooth for audio output.

Problem: Cannot find audio book/songs or incorrect number of songs/files.

Solution:

• Verify that your audio files are in a supported format (MP3, WMA, APE, FLAC, WAV, AAC-LC, ACELP, OGG).
• Use the "Refresh" function under the music icon to rescan the library after adding or deleting songs.

Problem: MP3 player scan takes a long time.

Solution: A full scan is activated when you reinsert the memory card while the device is on, or when you use the refresh function after adding/delating songs. The more tracks saved, the longer the scan will take. This is normal behavior.

Problem: Player is frozen or not working.

Solution: Use a thin object (like a needle or paperclip) to press the reset button located in the microphone hole on the left side of the MP3 player. This can resolve most software-related issues.

Problem: All songs are gone after factory settings reset.

Solution: No, songs are retained unless you perform a "format disk" operation. Factory reset only clears settings, not user data.
