Working principle: Radio remote control technology is usually used to use radio waves to transmit the control signal through coding (fixed code or rolling code) to encode and then emit the signal. The garage door receiver receives and decodes the signal, and the driving motor realizes the operation of opening and closing the door.
Structure composition: It is generally composed of the transmitting part and the receiving part. The transmitting part is the remote control, which has two types of whole machine remote control and remote control module; the receiving part is usually installed in the garage door motor control box, and there are two receiving modes: ultra-exterregeneration and super-regeneration. The ultra-exterrence type has good stability and anti-interference ability, and the ultra-regeneration type is small in size and cheap in price.
Functional features: It has basic opening, closing and stopping functions. Some remote controls have learning storage functions, which can match multiple transmitters or receive multiple remote control signals.
Type distinction: From the coding method, there are fixed code and scroll code remote control. The fixed code has a small coding capacity and poor confidentiality, which is used in occasions with low confidentiality requirements; the rolling code automatically changes the code after each launch, with strong confidentiality, large coding capacity, and small error code. In terms of appearance and usage, there are conventional handheld remote controls and small thumb-shaped copy remote controls, etc. The latter is easy to carry and can copy the code of other remote controls through simple operations.
Use and maintenance: Make sure that the battery is sufficient when using it. Press the door or close button to control the garage door. During use, you should pay attention to the operation of the garage door. The performance of the remote control should be checked regularly to avoid strong impact or immersion in water. If you find that the control distance is shortened or the keys are not sensitive, you need to repair or replace the battery in time.
Matching method: Generally, you need to find the "Learning" or "Pairing" button on the garage door motor control box first, and press the motor to enter the pairing mode. At this time, quickly press the door opening button on the garage remote control. If the indicator light is always on, it means that the pairing is successful. There may be differences in the pairing methods of different brands and models.
