Rapid, clear well done as all the scheme I downloaded from this site. Great job very functional and very useful
;
Great copy of the manual, has all information required for servicing,
;
I work at an authorized service center and I can tell if a manual is as it should be. This one is. It may be a scan, but a very good one at that. The interesting part for me was the curcuit diagram which was scanned at high quality, making it as good as the original. I will definitely be back as a customer. I need not say this, but I will: the price was the best. Thank you owner-manuals.com .
