3. The operating frequency of the transmitter and receiver must be same.

Generally, people use 315MHz the most in China, while 433MHz in Western

Europe.

Matching code:

1. There is a 8-pin soldering pad on the PCB of transmitter and receiver chips.

It is used to set address code by soldering. Pls see the following pictures:

2262 pad:

2272 pads:

2. Use an electric iron to solder the middle pin up/down to set address code.

If the soldering ways on the transmitter and receiver are same, they can

work together.

Please mind the direction and see the below diagram for reference:

L=Low, H=High

Transmitter: Receiver:

LX/PT/SC2262 LX/

PT/SC2272

Now, the address code on transmitter is as same as the receiver, they can work

together now.
