Manual is in German but complete. I needed this one to fix a long lasting problem with the internal PSU of the camera. Most of the capacitors begin to leak after a few years wich results in the inability to power on the camera. When you try to turn it on the power led flickers and the unit directly turns off. Thanks to this manual I was able to locate all bad cap's and to dis- and reassemble the camera without any problems.
