Description:

This is a wireless remote control switch with feedback functionality—no configuration is required. As long as the

transceiver’s “Frequency and ID” settings are matched, the device can be controlled. The built-in LED indicator

on the transmitter provides visual feedback on the receiver’s switch status.

Application:

Smart Home, Home Automation; Identification system; Remote Motor Control System CCTV Camera PTZ Control;

Security system; LED dot matrix screen; Ship remote control system Farm remote gate control system

The first use process:

1. Confirm that the frequency and ID of the receiver and transmitter are the same.

2 Power on the receiver first, the PWR light is on

3 Power on the transmitter again; the PWR light will flash, and the PWR light on the receiver will flash simultaneously,

indicating that the pairing was successful.

4 At this time, the relay on the receiver can be remotely controlled through the input port on the transmitter.

NOTE:To install the antenna, remove the top cover of the housing.When using two transmitting devices

at the same time, the frequency or ID number cannot be the same When using two receiving devices at

the same time, the frequency or ID number cannot be the same
