- Clean Surface: Clean the surface of the joystick controller where the keypad will be applied. Ensure it is free of dust, debris, and adhesive residue for optimal adhesion.
- Prepare New Keypad: Gently peel the protective backing from the adhesive side of the new AlveyTech keypad. Avoid touching the adhesive surface.
- Apply New Keypad: Align the new keypad precisely with the button cutouts and edges of the joystick controller. Press firmly and evenly across the entire surface to ensure secure adhesion.

4. Maintenance
To ensure the longevity and proper function of your AlveyTech keypad, follow these simple maintenance guidelines:
- Cleaning: Wipe the keypad surface periodically with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the keypad material or markings.
- Inspection: Regularly inspect the keypad for any signs of wear, damage, or peeling. If the keypad shows significant wear, consider replacement to maintain optimal functionality.
- Environmental Protection: While the keypad is designed for durability, avoid prolonged exposure to extreme temperatures, direct sunlight, or excessive moisture, which can degrade the material and adhesive over time.
5. Troubleshooting
If you experience issues with your AlveyTech keypad after installation, consider the following:
- Buttons Unresponsive: Ensure the keypad is securely adhered to the joystick controller. If buttons remain unresponsive, the underlying joystick electronics may require service.
- Keypad Peeling: If the keypad begins to peel, ensure the surface was clean and dry during installation. Re-adhere if possible, or consider replacing the keypad if the adhesive has failed.
- Incorrect Function: Verify that the keypad is correctly oriented on the joystick. If functions are incorrect, consult your power chair's main instruction manual or a qualified technician.
For persistent issues not resolved by these steps, please contact AlveyTech customer support or a certified mobility equipment technician.
