I've just bought a second-hand cassette deck (without instructions

trouble with a

1. "ATC" - I believe this is some kind of auto-tuning system - but
neither of the two controls ("select" and "off/on" pushbuttons) appear
to do anything, or make anything appear on the display.

2. Timer. By the power button there is a three-way switch marked
"timer", where the positions available are "rec", "off" and "play."
Again, I cannot seem to make it do anything!

Can anyone advise me what these are for?

Many thanks.

You can download a user manual for the RS-BX646 here.
