I picked up a General Instruments 450I Receiver yesterday with the original remote control, but so far I haven't been able to control the receiver with the uhf remote (model urc 45t). I turned on the receiver, pushed the Sat button, even the sat/tv button, but couldn't control any function on the receiver. I've got new batteries in it & the lights flash on the remote when I push a button. Because it didn't have batteries in it when I got it, I'm hoping that it just might need to be reprogrammed. And by the way, I found the manual for the receiver in the "fta manuals section" here on satelliteguys. Thanks to everyone who shares these user guides! I'm still looking for a dish, but hey, I've got a dish mover now. I hope the remote is not defective, so if anyone has any ideas, I would appreciate the input. The receiver manual says to check the remote control guide.
