The receiving controller has the characteristics of high confidentiality, large storage capacity, stable performance and low power consumption, and is easy to use. It does not need to use traditional jumpers or dial switch codes, just pair the remote control with the receiving controller and store ( Code matching) can be used together. Each receiving controller can pair and store multiple transmitters (remotes). If the learned remote control is lost during use, you only need to clear the information stored in the receiving controller (clear code), the lost remote control will not be able to perform related control operations on the receiving controller, which can avoid losing the remote control The case where the receiver controls the receiving controller. 1.
