Maintenance manual for electric door remote control

电动门已经在我们的生活中被广泛使用，从企事业单位进出车辆的大门，到商场门店，工厂、银行，再到普通老百姓的住宅，随处可见电动门身影。

Electric doors have been widely used in our lives. From the entrance and exit of enterprises and institutions to the stores, factories, banks, and ordinary people's houses, electric doors can be seen everywhere.

由于其造型美观、功能齐全、控制方便、停电时也可手动操作，所以被大量使用。既可远程遥控控制，也可近程开关操作。

Because of its beautiful appearance, complete functions, convenient control and manual operation during power failure, it is widely used. Not only remote control, but also short-range switch operation.

电动门遥控是控制电动门开、关、停的常用工具，它们的载波频率通常为315mHz或者433mHz。编码方式常见有两种类型，即固定码与滚动码两种。固定码因其造价低廉，被广泛应用到早期的遥控产品当中，而滚动码是可以看作是固定码的升级产品，具有较好的保密性，重码概率极小等特点，被广泛使用到保密性较高的地方。

Electric door remote control is a common tool to control the opening, closing and stopping of electric doors. Their carrier frequencies are usually 315mHz or 433mHz. There are two kinds of coding methods, that is, two kinds of fixed and rolling codes. Because of its low cost, fixed code is widely used in early remote control products, and the rolling code is an upgraded product which can be regarded as a fixed code. It has the characteristics of good security, low probability of re code and so on. It is widely used in high secrecy.

电动门遥控器是损耗品，一般频繁使用1~2年就需要更换，良好的使用习惯，可以延长遥控器的使用寿命。遥控器在使用一段时间后，经常会遇到：某一功能键失效，遥控距离越来越短，遥控操作不起作用等现象。遇到这些情况，先检查有无下列情形：

The electric door remote control is a wastage product. It usually needs to be replaced frequently in 1~2 years. Good usage habits can extend the service life of the remote controller. After being used for a period of time, the remote control often meets the following phenomena: failure of a function key, short distance of remote control, and remote control operation. In these cases, check whether there are any of the following situations:

1、检查发射器电池电压是否低于10V

1. Check whether the battery voltage of the transmitter is less than 10V

2、检查附近有无电磁干扰

2. Check whether there is electromagnetic interference in the vicinity

3、遥控器是否受潮，按键内有无污垢

3. Whether the remote control is dampened or not, there is dirt in the button

4、检查控制器电源电压是否偏低

4. Check whether the power supply voltage of the controller is low
