Many friends often ask how to pair the remote control. Due to the different matching methods of remote control, there is no unified standard process. The remote control is divided into infrared remote control and wireless remote control. Next, we will show you how to match these two remote controls, hoping to provide you with some reference when using the remote control.

Infrared remote control is a way of using infrared to transmit signals. It is mainly composed of sending and receiving parts.

The sending part emits light through infrared ray, and then sends it again. The key component of the receiving part is the infrared receiving diode. In practical applications, the reverse bias voltage should be added to the infrared receiving diode before normal operation.

Infrared remote control matching process:

1、 The set-top box can be equipped with remote control and TV remote control;

Second, press the learn button of the TV remote control for three seconds, and you can see that the red light of the paired remote control starts flashing;

3、 Press and hold the power button of the TV remote control for ten seconds and keep it still. At this time, the red light will be on all the time;

4、 Then put the set-top box remote control and the TV remote control close to each other, and the distance is within 3mm.

5、 After pressing the button to learn, the red light will flash, and then flash after three times, and then the learning will succeed;

6、 Then repeat the operation and learning of other buttons, and then press the learning button to exit.

The wireless remote control is relatively simple and is also our most commonly used device. When these institutions receive wireless signals, they will send action instructions to the corresponding equipment and complete the operation.

During operation, this wireless remote control has no directionality and will not be blocked. Therefore, in addition to electric doors, many things in life, such as lights and refrigerators, can also be controlled by wireless remote control.

The wireless remote control is paired as follows:

1. Prepare a copy remote control and an original wireless remote control. It should be noted that the frequencies of the two remote controls are the same;

2. With the original remote control in one hand and the copy remote control in the other hand, press the required copy button respectively when the two remote controls are close. After the LED flashes three times, the indicator light is always on, indicating that the copy is successful;

3. Refer to the previous step for other key copying methods.
