Just got this Manual downloaded... Scan is PERFECT! This is EXACTLY what I needed. However, please update your site info to state that it may take more than \"a few hours\" to have the download available after payment - - - I had to wait 4 days, in my case. Otherwise, I am very happy with this!!! Thanks! --- User-Manuals.COM comment We\'re sorry for delay, we had major problem with our download server, but all is ok now and downloads works as previous.

I was thinking I will never find this manual. User-Manuals had saved my Teac V-7010 which is full of specific functions. Superfast service, excellent document. Thank you very much!
