Teac A-2300SD questions

Hi, I need to know a few things about this deck:
1. In changing the capstan belt, is it accessible from the front or the rear panel ?
2. FM COPY on /off switch: I think if should be left OFF, since no FM stations I know of broadcast in Dolby B any longer.Am i correct. Is is used for anything else than that?
3. Rec bias and EQ switches, Is #1 on both used for older tapes, like pre- 1970 tapes ? is # 2 for low noise, like ampex 406,456?

Thanks, Bob
