- Replace the battery in time when the remote transmitter voltage is low to get stronger signal transmission.
- Slightly stretch the antenna on the receiver for better signal reception.
- Ensure power is disconnected before making any wiring connections.
- The output type is passive output / potential-free contacts.

Troubleshooting
If the receiver and transmitter cannot operate normally, try the following steps:
- Check if battery power is used up. The indicator LED on the remote transmitter does not light up or is dimly lit. Replace with new CR2 batteries.
- Check if your receiver is wired correctly. Make sure the wiring to NC, COM, NO terminals is correct.
- Ensure the receiver is within range (up to 50 meters in open areas) and the antenna is not obstructed.
- Avoid placing the receiver near other strong RF signal sources that may cause interference.
- Reprogram the receiver and transmitter. Usually this can solve many problems.
- If the problem still remains, please contact us.
