Jason Gaunt - 01/26/2008

This manual is for both the EU and Australian version of the CCD-TR55(E) Camcorder, as stated it includes both the users manual and the service manual. The quality of the manual is very good but it is only black and white (not full colour) and ultimately it is just a scan, so 4/5 from me.

Grace Towers - 05/22/2008

Very nice clear manual with specifications, exploded views and schematics, been searching for one of these for years. Thanks.
