I have a Denon 3802 and I am unable to change FM stations from the remote. I have selected "AMP", input to tuner, and have done the automatic station selection. I can hear the FM station fine. I have also re-initialized the receiver processor, and reset the remote, but still no luck. I've read the manual and followed it to the letter. Maybe my remote is defective. When I press the channel buttons, + and -, should there be a display on the remote that says channel + or something. Mine only says "AMP", with no additional characters. I can tune it manually by pushing the button on front and turning the tuning know fine. Is my remote broken?
