Function description
(1) Copy code checking operation
If the remote control has checked the code, the code can be checked only after the code is cleared. Code matching operation: press the single key of the copied remote control and the copy remote control at the same time, until the indicator light of the copy remote control changes from flash to constant light, then release the two remote control keys, and code matching is successful. Other keys are also operated in this way until all keys are copied.
(2) Clear code operation
At the same time, press and hold the lock and car keys of the copy remote control until the indicator light flashes quickly, and then briefly press the lock key three times to clear the code (during this process, the car key is kept pressed).
(3) Recovery code operation
Press and hold the unlock and ring buttons of the copy remote control at the same time until the indicator light flashes quickly, and the remote control code that was cleared before can be restored.

Copy chip
PT2242, PT2260, PT2262, EV1527, 527, PT2240, SMC918, HT-12E, AX5326-3, AX5326-4, AX5026, HT600, HT680, HT6207, HT6010, HT6014, MC145026, HT640, etc

Matters needing attention
(1) The battery voltage cannot exceed the operating voltage.
(2) When copying the remote control, try to keep the two remote controls close to each other, otherwise the copy exception will occur.
(3) In the environment with large wireless interference, the transmission distance may be reduced.
(4) Do not use it in a humid environment, otherwise the remote control may be damaged.
