6. Operating Instructions
6.1 Recording Cassette to MP3

- Automatic Mode: Slide the A/M switch to 'A'. In this mode, the converter attempts to detect pauses between songs and automatically creates separate MP3 files for each track.
- Manual Mode: Slide the A/M switch to 'M'. In this mode, you manually start and stop the recording, creating one continuous MP3 file until stopped.
Recording Steps:
- Ensure a USB flash drive is inserted and the cassette tape is loaded.
- Select your desired recording mode (Auto or Manual).
- Press the 'Play' button on the converter to start playing the cassette.
- Press the 'Record' button. The LED indicator will light up, indicating recording is in progress.
- To stop recording, press the 'Record' button again. The LED indicator will turn off.
- Press the 'Stop' button to stop cassette playback.
Recorded MP3 files will be saved in a folder named 'TAPECAPTURE' on your USB flash drive.

7. Connecting to External Devices
- Headphones/Speakers: Connect the included headphones or your own 3.5mm audio cable to the headphone jack for private listening or connecting to external speakers.
- Audio Input (AUX): Use a 3.5mm audio cable (not included) to connect an external audio source (e.g., another MP3 player, CD player) to the AUX input port. You can then record audio from this source to your USB flash drive by following the recording steps.
8. Troubleshooting
- No Power: Ensure batteries are correctly inserted or the USB power cable is securely connected to a working power source.
- No Sound during Playback: Check headphone connection, adjust volume, ensure cassette is playing, or MP3 files are present on the USB drive.
- Recording Not Starting/Saving: Ensure a USB flash drive is inserted and has sufficient free space. Check if the USB drive is formatted to FAT32. Press the 'Record' button firmly.
- Poor Recording Quality: Ensure the cassette tape is in good condition. Clean the tape heads if necessary (see Maintenance). Avoid recording in noisy environments.
- Automatic Mode Creates Too Many Files: The automatic mode's sensitivity to pauses can sometimes split a single song. Use Manual mode for precise control over track separation.
