5. Troubleshooting
- Remote control not working: Check the remote control battery (CR2016 3V). If the red indicator light does not turn on when a button is pressed, replace the battery.
- Switch makes a 'TI TA' sound: This sound is normal during operation and indicates the relay is engaging or disengaging. It does not signify a malfunction.
- Reduced remote range or intermittent operation: Ensure there are no significant obstacles between the remote and the receiver. Large metal objects, thick walls, or other RF interference sources can reduce the effective range. Verify that the receiver's antenna is unobstructed.
- Device not responding after wiring: Double-check all wiring connections for correct polarity and secure terminals. Ensure the power supply to the receiver is within the specified 12V-72V range. Confirm that the remote control is properly paired with the receiver.
