Troubleshooting
If the receiver and transmitter cannot operate normally, try the following steps:
- Remote not responding: Ensure the receiver is powered on and the remote control has a working battery. If the receiver was recently reset, re-pair the remote control following the programming instructions.
- Appliance not turning ON/OFF: Check all wiring connections for tightness and proper insulation. Verify that the power supply to the receiver is active and within the specified voltage range (AC 85V-250V).
- Reduced remote range: Large metal objects, thick walls, or other radio frequency devices can interfere with the signal. Try repositioning the receiver or remote control.
- Indicator light not flashing during programming: Ensure you are pressing the learning button correctly and for the appropriate duration as specified for each mode.
- Battery check: The indicator LED on the remote transmitter does not light up or is dimly lit – replace the battery.
Maintenance
- Keep the receiver and remote control clean and free from dust and debris.
- Avoid exposing the devices to extreme temperatures, direct sunlight, or moisture.
- Replace the remote control battery when its performance degrades.
- Periodically check wiring connections for any signs of wear or damage.
