Denon avc 3000

Hi, just bought this second hand, don't have the manual, the display says`"bypass", and I can't turn it off, the thing works. Anyone know why this is or what its about? and does anyone out there have a manual for this? I'll gladly buy a copy. thanks
Try pressing the "mode surround" button which will switch the various options available in the surround mode and turn off the bypass feature. When you press "bypass" it cuts the surround mode out which give regular stereo playback. I have a Denon AVC 3020 which is very similar to the 3000. I have also owned the
AVC 3000 and an AVC 1000. I have a service manual for the AVC1000 which explains some of the features.
