Okay, I just got my 15-1994 today mostly because of this forum. First problem, I have an RCA Receiver (RV-9968 or RV-9978). None of the codes (0531 in the book and 0054, 0360 and 0056 on websites) work for it. Actually, I'm using the AUX 1 button and 0054, 0360 and 0056 are invalid (I get the one long blink instead of blink blink when I try to program it in). What do I need to do to get it to control my receiver? Thanks.
