Well, after my last post stating that the drawing in the manual was wrong, I put on my new glasses and realized my error.? After having this scope all these years I had it fixed in my mind that it was a 485.? With blurry glasses that's what I saw on the face plate, I thought.? Well, the new glasses let me see the front panel clearly and I see it is a 465.? Boy, do I feel dumb.? Since much of the advice given above was from 465 users, I can certainly use it to aid my trouble shooting.? I imagine I can find the 465 manual at the same sites previously referenced for the 485.

I do apologize for my faux pas.
