Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
best regards

I will definitely be back for more information when I need it.

The service manual when downloaded and printed out was clear and easy to read. I would have liked to have been able to enlarge some details, but this was not possible as the file permissions did not allow this. The service was very good. The time taken from placing my order to downloading the document was only a few minutes.

The manual is useful for trouble shooting for an old instrument. It saved money,and let me enjoy DIY.

Perfect source of information for replacing the HDD and performing general diagnostics.
