Get a new electric door remote control, clear the code, and press the two buttons in the upper row at the same time. When you see the indicator light flashing continuously, release both buttons at the same time, and the code is cleared successfully. Put the old and new remote controls together and press two buttons in the same position at the same time. When you see the indicator light flashing, release the two buttons, and the first button matches successfully. If the match button is pressed, the indicator light will be on all the time, indicating that the key matching has been successfully completed.
Electric door remote controller is a remote control device that uses radio signals to remotely control various mechanisms in the distance. As a kind of remote controller complementary to infrared remote controller, electric door remote controller has been widely used in garage doors, electric doors, road brake remote control, burglar alarm, industrial control, wireless smart home and other fields.
Influencing factors of electric door remote controller
1, transmission power: if the transmission power is large, the distance is long, but it consumes a lot of power and is easily disturbed;
2. Receiving sensitivity: it improves the receiving sensitivity of the receiver and increases the remote control distance, but it is easy to be disturbed and cause misoperation or out of control;
3. Antenna: Linear antennas are used, which are parallel to each other and have long remote control distance, but occupy a large space. When in use, stretching and straightening the antenna can increase the remote control distance;
4. Height: The higher the antenna, the farther the remote control distance, but it is limited by objective conditions;
5. Obstacles: The wireless remote controller uses the UHF frequency band specified by the state, and its propagation characteristics are similar to those of light, with straight line propagation and small diffraction. If there is a wall between the transmitter and receiver, the remote control distance will be greatly reduced. If it is a reinforced concrete wall, the influence will be greater because of the absorption of electric waves by conductors.
