遥控器常见问题：

Common problems of remote control:

●遥控器按下按键时，遥控器指示灯不亮，或者遥控器指示灯很暗

When the remote control press the button, the remote control indicator is not lighted, or the remote control indicator is dim.

●遥控器按下按键时，主机没有任何反应

When the remote press presses the key, the host does not respond.

●车库门正运行时，按遥控器不能使其停止或遥控停止距离很近

When the garage door is running, it can not be stopped or remotely controlled by the remote control.

●遥控器遥控距离变近

Remote control distance becomes closer.

●遥控器遥控距离有时近有时远

Remote control distance is sometimes near and sometimes far away.

●更换电池后，遥控器无反应

When the battery is replaced, the remote controller has no response.

常见接收板问题

Common receiving board problem

●接收板有时有反应，有时无反应

Receiving boards sometimes react, sometimes no response.

●有时主机自动开门或关门

Sometimes the main machine opens or closes automatically.

●安装后遥控距离比较近

After installation, the remote control distance is relatively close.

●使用一段时间后，接收板没有反应

After use for a period of time, the receiving board has no response.

●使用一段时间后车库门运行不能到顶或不能到底

After a period of time, the garage door can not run to the top or not.

●遥控器按下按键时，遥控器指示灯不亮，或者遥控器指示灯很暗

When the remote control press the button, the remote control indicator is not lighted, or the remote control indicator is dim.

遥控器电池电池没有电，或者电池电量偏低，更换电池后（注意正负极性），如果指示灯仍然不亮，检查按键有无损坏、氧化（如果有的按键有反应，有的没有，很大可能性为按键损坏，也有可能电路上的二极管损坏），再不行可能是遥控器已损坏。

If the indicator light is still not on, check the button for damage and oxidation (if there is a response to the button, some are not, it is very likely that the button is damaged, or the diode on the circuit is damaged), no more. Row may be damaged by remote control.

●遥控器按下按键时，主机没有任何反应

When the remote press presses the key, the host does not respond.

首先检查遥控器是否为原配的遥控器，如有两个遥控器检查另一个遥控器是否有反应，如果另外一个遥控器有反应，可能此遥控器的密码丢失，按下学习按纽，LED灯闪烁，按两次遥控器的同一个按纽，如果LED灯快速闪烁，说明学习成功，如果LED灯继续慢闪，说明学习不成功，如果学习成功，仍然不能遥控，说明接收板输出有问题，或者很大可能为主控板有问题，如果反复学习都不成功，可能遥控器损坏；如果任何一个遥控器都不能遥控，并且学习也不成功，可能接收板有问题，检查接收板灵敏度及其它相关电路。

First check whether the remote control is the original remote control, if there are two remote controllers to check whether the other remote control reacts, if the other remote control reacts, the password of the remote control may be lost, press the learning button, LED lights flashing, press the same button of the two remote controllers, if the LED lights flashing quickly, instructions Successful study, if the LED light continues to flash slowly, that learning is not successful, if successful learning, still can not be remote control, that is, receiving board output problems, or very likely to have problems with the main control board, if repeated learning is not successful, the remote control may be damaged; if any remote control can not be remote control, and learning It is also not successful. There may be problems in the receiving board, check the sensitivity of the receiving board and other related circuits.

密码丢失可能性较少，但不能完全杜绝丢码，如果一台主机经常丢失密码，需要更换解码电路。

Password loss is less likely, but it can not be completely eradicated. If a host often loses the password, it needs to change the decoding circuit.

●车库门正运行时，按遥控器不能使其停止或遥控停止距离很近

When the garage door is running, it can not be stopped or remotely controlled by the remote control.

车库门正运行时不能使其停止运行，主要原因是电机运行时产生大量很强的电磁波，干扰接收部分电路的电源，在电源上产生大量杂波，使遥控距离变得很近，可以采取以下方法解决：

The garage door can not be stopped when it is running. The main reason is that the motor produces a large number of strong electromagnetic waves when it is running, interferes with the power supply of the receiving part of the circuit, generates a large number of clutters on the power supply, and makes the remote control distance very close. The following methods can be adopted to solve the problem:

1、在接收电路及主控电路的电源和地上加磁珠、磁环、电感等器件，并且多加滤波电容等滤波器件。

1. The power supply of the receiving circuit and the main control circuit and the devices such as magnetic beads, magnetic rings, inductances are added on the ground, and more filter devices such as filter capacitors are added.

2、如果能把接收电路和主控电路屏蔽起来也会有较好的效果。

2, if you can shield the receiving circuit and the main control circuit, you will get better results.

3、接收板和主控板安装位置尽量离电机远一些。

3, the receiving board and main control board installation position as far as possible away from the motor.

4、在电机两极上加装滤波及脉冲的元件，尽量把电机屏蔽起来。

4. Install the filter and pulse components on the poles of the motor to shield the motor as much as possible.

5、把接收天线用屏蔽线拉出来，放到离电机稍远的一些地方，有利增加遥控距离。

5. Pull the receiving antenna out with the shield wire and put it somewhere farther away from the motor, which is advantageous to increase the remote control distance.

以上这些措施可帮助提高遥控的停止距离，但一般情况下，停止遥控距离要比启动的遥控距离近一些。

These measures can help to increase the remote control stop distance, but in general, the stop remote control distance is closer than the start remote control distance.

●遥控器遥控距离变近

Remote control distance becomes closer.

遥控距离逐渐变近，一般情况下为遥控器电池电量逐渐变少，更换遥控专用12V电池后既可，如果仍然不能解决问题，可能主机接收板有问题（但一般主机接收板问题较少），如果有时远有时近，可能为周围环境的影响，参照下一条问题。

Remote control distance gradually closer, generally for the remote control battery gradually less, after replacing the remote control dedicated 12V battery can, if still unable to solve the problem, the host receiving board may have problems (but the general host receiving board less problems), if sometimes far and sometimes near, may be the impact of the surrounding environment, refer to the following One problem.

●遥控器遥控距离有时近有时远

Remote control distance is sometimes near and sometimes far away.

遥控器距离有时远有时近，有可能为周围环境的电磁波干扰，如果地处无线电台、电视台附近，或者BB机发射台、移动电话中继站、雷达站或其它发射台站附近，电磁干扰很大，距离较近属正常，也有一些工业设备如高周波塑压机等也可产生很大干扰，如果在这些附近，也会引起距离近，如果排除这些的干扰，检查一下接收天线接触是否良好？

Remote controllers are sometimes far and sometimes near, and may be interfered by electromagnetic waves from the surrounding environment. If they are located near a radio or television station, or near a BB transmitter, mobile phone relay station, radar station or other transmitter station, the electromagnetic interference is very large and the distance between them is normal. There are also some industrial equipment such as high cycle plastic compression. Machine and so on may also produce the very big interference, if in these vicinity, also may cause the close distance, if eliminates these disturbances, checks whether the receiving antenna contact is good?

●更换电池后，遥控器无反应

When the battery is replaced, the remote controller has no response.

更换电池后，遥控器无反应，请检查电池极性有无接反？电池片接触是否良好？如果接触良好，遥控器LED等应该会亮，如果LED灯亮，而主机无反应，有可能遥控器编码芯片损坏，因为此芯片为静电敏感器件，特别在北方，用手触摸电路板容易损坏。损坏后只能更换芯片。

After the battery is replaced, the remote control does not respond. Please check whether the polarity of the battery is reversed. Is the battery contact well? If the contact is good, the remote control LED and so on should be on, if the LED light is on, and the host does not respond, the remote control coding chip may be damaged, because this chip is electrostatic sensitive device, especially in the north, touch the circuit board easily damaged by hand. Only chips can be replaced after damage.

●接收板有时有反应，有时无反应

Receiving boards sometimes react, sometimes no response.

首先检查遥控器有无问题，如果遥控器没有问题，再检查接收板天线、其它连接线及主板连线有无问题，如果这些都无问题，再检查按遥控时接收板有无输出，如果无输出即为接收板问题，再检查周围环境有无很强烈的电磁干扰，如果无问题，可能接收板存在问题，可能接收板晶体有时停振。

First of all, check the remote controller is not a problem, if the remote controller is not a problem, then check the receiving plate antenna, other connections and motherboard connections are not a problem, if these are not a problem, then check the remote control when the receiving board has no output, if no output is the receiving board problem, then check the surrounding environment has a very strong electromagnetic dry If there is no problem, there may be a problem in the receiving board, and sometimes the crystal will sometimes stop.

●有时主机自动开门或关门

Sometimes the main machine opens or closes automatically.

出现此问题，最大可能性为主控板CPU或接收解码CPU复位电路有问题，或者是震荡电路有问题，当出现停电又加电时，引起主控板驱动门有所动作，此时可用反复加电的方式实验是哪部分电路的问题，来改进此部分的复

This problem, the greatest possibility for the main control board CPU or receive decoding CPU reset circuit problems, or oscillatory circuit problems, when power failure and power-on, cause the main control board drive door to act, at this time can be repeated power-on mode experiment is which part of the circuit problem, to improve the part of the complex.
