6. Maintenance

To ensure the longevity and optimal performance of your Junsun Wireless Steering Wheel Control Button, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe the controllers. Avoid abrasive cleaners or solvents that could damage the plastic or LED lights.
• Storage: If not in use for an extended period, store the controllers in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery: The controllers are powered by internal batteries. If you notice a decrease in responsiveness, the batteries may need replacement. Consult a professional if you are unsure how to replace them.

7. Troubleshooting

7.1 Common Issues and Solutions

Issue: Controllers are not responding or functioning.

Solution: Ensure the receiver box is correctly wired to your Android car radio's power cable. Verify that the 'button learning' process has been completed successfully in your radio's settings. Check if the controllers' batteries need replacement.

Issue: Buttons are performing incorrect functions.

Solution: Re-enter the 'Steering Wheel Control' or 'SWC' settings on your Android car radio and repeat the 'button learning' process to re-assign functions correctly.

Issue: Controllers do not stick well to the steering wheel.

Solution: Ensure the surface of your steering wheel is clean and dry before applying the adhesive sticker. For best results, apply pressure for a few seconds after placement.

• Easy Installation: The installation is generally simple, primarily involving connecting the receiver box to your radio's power cable and then adhering the buttons. The most crucial step is the 'button learning' process within your Android radio's settings.
• Customization: Take advantage of the 'button learning' feature to customize each button's function to your preference, optimizing your driving experience.
