OK, this is from memory (it's been 15 years since I used a 465). The
center (red knob) is for a variable timebase. That should have a detent
all the way at one end of it's rotation. Put that knob in it's detented
position. There are two timebase knobs (one for the main timebase, one
for the delayed timebase). You can separate these two settings by
pulling on the inner gray (secondary?) knob and it will rotate
indepentent of the outer knob. These two timebase knbs should be locked
together AT THE SAME SETTING.

Also, make sure that you have the timebase selected properly - (I
remember a coulumn of pushbuttons) they are labeled something like A, B,
A inten B, A delayed B. what you want is 'A', or however it is labeled
for the main timebase.

When properly set up for simple measurements, the vernier control (the
multiturn silver knob) should have no effect.

The red knobs you see for each channel are for vertical (volts/div)
gain. These should also be in their detented positions.

A very quick google search came up with
http://www.aa4df.com/465475op.htm
He has the 465 and 475 (basically the same scope) manuals as a PDF file.
You can download it for $10.00 or buy a CD for $13.85. I don't know the
guy, but there were also other people selling manuals. Take a look.
You'll never get into all the things the scope can do without the
manual.
