Remote for shop extractor

[Antomakes]

That’s awesome! What sort of reprogramming did you need to do?

Wipe the memory in the existing remotes and start afresh with all uncoded remotes:
Press the side button on the black box 8 times to clear the memory. The existing remotes will no longer work. (Test to make sure)
Press the side button again but only 3 times. Green LED will illuminate.
Take one remote and press ON.
Green LED will blink.
Immediately press OFF on same remote.
Do the same on all remotes.
