Yeah- surprisingly, 998 is not working... I can check the house code but the IR543 is not lighting up or anything... no indication that IR is being received. RF control works fine... in fact, when I enter 998, the remote STILL controls things through my transciever and not the IR (So the RF housecode at least is fine). It's like it is not taking the "998" code... The LED on the remote blinks as per the manual... I think I am following the instructions... Maybe I'll see if it takes any codes to program say my TV or something... I wonder what the problem is...
