- Certain Buttons Not Working:
- Verify that the button is clean and not stuck.
- Confirm that the function you are trying to use is supported by your specific JVC unit model.
- For buttons under the sliding cover, ensure the cover is fully open.
- Intermittent Operation:
- This often indicates low battery power. Replace the batteries.
