Customer asked, when programming the SR-B1 compatible remote to receiver, which buttons emulate the hidden button on BFT Mitto
remotes?
Well, we have two types of SR-B1 casing, one is the round metallic casing, and the other is sliding cover 1234 casing.
On the sliding cover with 1234 buttons casing, the hidden button is 3 + 4 press together.
On the round metallic casing with gray buttons, the hidden button is 1 + 4 ( top + bottom ) press together.
After pressing hidden button combinations, you should observe the LED on receiver becomes steady on, indicating the hidden button code has been received by receiver.
