Are yo sure you're in the right spot for the IR emitter?
until I paired the remote to the box for RF, the front lip of rack shelf was blocking the IR receiver!
Don't follow you. It sounds like you're saying that pairing for RF somehow moved the cable box or the front lip of the rack shelf, unblocking the IR receiver.
