6. Maintenance
6.1. Battery Replacement
When the remote's performance diminishes, the range decreases, or it stops responding, it may be time to replace the CR2032 3V battery.
- Carefully open the remote casing. Refer to the product diagram for potential opening points.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery, ensuring the correct polarity (+ side up).
- Close the remote casing securely.
Dispose of old batteries responsibly according to local regulations.
6.2. Cleaning
Wipe the remote control with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or liquids, as these can damage the device's finish or internal components.
7. Troubleshooting
- Remote not responding or intermittent operation:
- Check Battery: Ensure the CR2032 battery is correctly installed and has sufficient charge. Replace the battery if it is low or depleted.
- Range: Move closer to the AYR Smart Door product. Bluetooth signals can be affected by distance and obstructions.
- Pairing: Verify that the remote is correctly paired with your Smart Door product via the AYR application. If necessary, attempt to re-pair the device.
- Interference: Minimize potential sources of wireless interference (e.g., other Bluetooth devices, Wi-Fi routers) near the remote and the Smart Door product.
- Malfunction when paired with multiple devices:
- Some users have reported issues when attempting to control multiple Smart Door devices with a single remote. If you experience inconsistent behavior, consider using separate INT_Key Pro remotes for each Smart Door product. For multi-device pairing best practices, consult AYR customer support.
- Poor range or remote must be very close to the door to operate:
- This often indicates a weak battery. Replace the CR2032 battery with a new one.
- Ensure there are no significant physical obstructions (e.g., thick walls, metal objects) directly between the remote and the Smart Door product.
If these troubleshooting steps do not resolve the issue, please contact AYR customer support for further assistance.
