Gee, and I thought I was mechanically minded - I feel like a kid with one of those silly puzzles...

ACC Type III - out and on the coffee table: I'm going in after the relays - how do I get the buttons and surrounding bezel off the front?

And/or: in what order do these things come apart? I've had the cover off in the past, just to inspect the solder on the big board, but have not gone further...
