Maintenance
Remote Control Battery Replacement
The remote control uses a CR2025 coin cell battery. If the remote's indicator light does not illuminate or the remote becomes unresponsive, the battery may need replacement.
- Locate the battery compartment on the back or side of the remote control.
- Open the compartment using a small screwdriver or by sliding the cover.
- Remove the old CR2025 battery.
- Insert a new CR2025 battery with the positive (+) side facing up.
- Close the battery compartment securely.
Troubleshooting
Remote Control Not Responding
- Check Battery: Ensure the remote control battery (CR2025) is not depleted. Replace if necessary.
- Re-pair Remote: If the battery is good, the remote may have lost its pairing with the receiver. Follow the "Pairing the Remote Control" steps in the Setup section to re-establish the connection.
- Power Cycle: Disconnect power to the LED controller for 10 seconds, then reconnect. Test the remote again.
- Obstructions: While RF technology works through walls, extreme metal obstructions or very long distances may reduce signal strength. Ensure the receiver is not completely encased in metal.
