Features: Superheterodyne acceptance module, the radio is stable, the remote control distance and sensitivity are not affected by the climatic environment and other factors, which is impossible for other products that accept the circuit. Digital coding, using imported digital IC chips for encoding, will not interfere with each other, and will not be affected by external obstacles. Easy to install, just need to connect our remote control switch to the light fixture or small appliance, you can realize remote control, no need to code. Remote control by wall, wireless remote control can be carried out by partition wall. Intelligent learning, power on, red indicator light, press the learning button, the learning indicator lights, press any button on the remote control, the learning indicator flashes, the relay emits an action sound, and the learning is completed.

Turn off the power to operate, and use it after the test is confirmed to be correct. 2. When the voltage of the remote control is insufficient, please change the battery in time (the remote control distance becomes closer when the remote control battery voltage is insufficient). 3. When using wireless electronic products, care should be taken to avoid metal masks, large electronic devices, electromagnetic fields, etc., which have strong interference sources, to avoid remote control and short receiving distance or to work normally. 4. Do not use this electronic product abnormally. Abnormal use will reduce the performance and longevity of the product. In severe cases, damage to the product will also bring hidden dangers to your safety.
