To ensure the longevity and optimal performance of your iSound Car Stereo Cassette Adapter, follow these general care guidelines:
- Cleaning: Wipe the adapter with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.

6. Troubleshooting
If you encounter issues with your iSound Car Stereo Cassette Adapter, consider the following common problems and solutions:
- No Sound or Intermittent Audio:
- Ensure the 3.5mm audio jack is fully inserted into both the adapter and your audio device.
- Verify your car stereo is set to "Tape" or "Cassette" mode.
- Check the volume levels on both your car stereo and your portable audio device.
- Try ejecting and reinserting the cassette adapter into the car stereo.
- Test with a different audio device or a different cassette adapter if available, to isolate the problem.
- Static or Background Noise:
- Ensure all connections are secure.
- Adjust the volume on your portable device; sometimes a very low or very high output can introduce noise.
- Some car cassette players may inherently produce a slight mechanical noise; this is often a characteristic of the car stereo itself.
- Cassette Adapter Ejects or Stops Playing:
- Some older cassette players may have mechanisms that are sensitive to the adapter's internal gears. Try reinserting the adapter.
- Ensure the adapter is fully seated in the cassette deck.
