Servus! Yesterday I got a Hoffmann Geodyna 88 at a reasonable price. Dan device is complete as far as possible. When switching on it shows an error code E48. My questions are: – What does the error mean, what damage does it indicate and is a repair possible? – Where can I get a manual and a repair manual? – Where can I get spare parts if necessary? Thanks in advance for your efforts and nice greetings! Helmut
