Veramente completo, dettagliato e perfetto nella visione. Perfect, thanks!
 ;
Fully functional usable service manual. Considering the age of the manual and device quality was better than expected
;
Thank you very much, I've been very happy to find this manual on "Owner Manual". It's a perfect copy and it has been really useful for my work!

It took about 24-hours after my payment before I was able to get to the download. Apparently, payment processing is not 100% automated. That is no big deal, just be aware of that going in.
After I got to it, it was in good shape, easy to read, etc. Not some cheap FAX copy looking thing.
Also, this site was the cheapest I found. Another Plus!

Good price, very legible manual, exactly what I needed -- but had to wait a day to actually get the download of the manual. Would have preferred to download it immediately after payment rather than waiting for someone to "process" my order. I was surprised that I had to wait that long.
