Phenomal manual great resoulution and very legible. Will become very helpfull in future for parts and service.

Nadia Yakunina - 06/19/2007

It was so difficult to find this manual on the internet - thanks a lot for making it so easy and simple. Incredibly handy. AND. It looks you make so many people happy for such small money. Good job!

Othmar Herbst - 01/13/2008

PDF contains : - schematics, but a little un-sharp. - disassembly instructions, accurate drawings - description of test-modes
