• Maximum load current: 2A

Warning

• Ensure the power supply voltage matches the receiver's specified range (DC 3.6V-30V).
• Do not exceed the maximum load current of 2A.
• Disconnect power before performing any wiring or maintenance.
• Keep the device away from water and high humidity environments.
• Do not attempt to disassemble or modify the device.
• Usually the receiver and transmitter have been paired in factory. If not, reprogram them.

1. Press the learning button the desired number of times (4, 5, 6, or 7). The indicator light will turn on.
2. Press any button on the transmitter. The indicator light will flash and turn off. Succeed.

Reset

To clear all paired transmitters from a receiver, press the learning button 8 times. The indicator light will flash 8 times and then turn off, indicating all stored transmitters have been cleared.

Troubleshooting

If the receiver and transmitter cannot operate normally, try the following steps:

• Device not responding: Check wiring and power (indicator light should flash). Ensure transmitter batteries are not depleted. Verify correct pairing. Check distance and obstacles.
• Intermittent operation: Ensure antenna is not obstructed. Minimize RF interference.
• Device turns ON/OFF unexpectedly: May indicate interference or incorrect mode. Re-pair and select correct mode.
• Receiver module gets hot: Connected device current exceeds 2A maximum load. Reduce load.

Maintenance

• Battery replacement (transmitter): Replace with 2x CR2016 batteries when range decreases. Open casing, replace with correct polarity.
• General care: Keep dry and away from extreme temperatures. Avoid dropping. Clean with soft, dry cloth. Do not use harsh chemicals.
