1) The method of the signal copy of the Powered Ascender PESCO Smart Spider PSJ120-7:
Press the learning key on the receiver ( new spare remote control ) and release it when you see that the indicator light flashes once and then goes out.
Press the “up” key ( on the original remote control ) to send the signal while the light ( on the new spare remote control ) goes out. When you see that the indicator light starts flashing, release the “up” key immediately. After that, the indicator light goes out again.
Press the “down” key (on the original remote control ) to send the signal after the light goes out. When the indicator light flashes again, the whole learning (signal copy ) process is well done.

2) Clearing the codes of the Powered Ascender PESCO Smart Spider PSJ120-7:
Press the learning key on the receiver ( new spare remote control ) until the indicator light flashes four times and turns into instant flashes. Then released it. After this, the code has been eliminated.
Whereas, if there are any mistakes in the learning (signal copy) procedure, clear the code first and then return to learn again.
