2023-07-31

It is very easy and convenience to be used for home/ store anti-theft alarm, electric cars, electric door, motorcycles, car alarms, all kinds of doors/windows controllers and other industrial control.

You can choose fixed code ,learning code and rolling code of this rf remote control.And you can choose copy code of it also.One the advantages of this type rf remote control switch is that it can copy other rf remote control and repalce it,and then can be used independent.We call it as D4 type remote control duplicator.D4 type duplicator can copy fixed code ,learning code and 18 rolling brands rolling code wireless remote comtrol switch.

Methods of operation:

1, Clear out code:

To Clear up test stored rf signal memory from factory by pressing the locking key and unlock the key at the same time, two seconds later, LED indicator light flashes three times, followed by a continuous fast blinking. Indicates that the remote control codes stored has been cleared out.

2, Duplicating (learning)

Hands are holding rf remote control , and the other are holding the duplicating rf remote control, 2 remote controls put together as close as possible, while pressing the remote controls two match button,(eg: A-A’,B-B’) three seconds later, LED indicator light flashes three times, followed by a continuous fast blinking. This indicates that this copy of the remote control switch buttons are same as copied on the gate remote control button codes . Several other keys are also according to the above approach to learning.

3, Recovery code

If the code copied have been mistakenly removed the gate remote control, you do not worry, the rf remote control can restore yourself. Method is pressing (up-down eg: locking key and bell key) two buttons (metal shell remote control on the left, the plastic shell garage door remote control on the right) at the same time ,3 seconds later, LED indicator light flashes three times, followed by a continuous fast blinking. This indicates that the original remote control codes have been restored.

4.The other way, you can delete all and relearn them again.
