The Innovage manual lists 6 codes for Konka, but nothing for Medion so I've tried the Chunghop manual. (I appreciate it's a different remote, but if as some are saying Tevion=Medion=Konka, one would expect some similarity).

The Chunghop manual lists 18 codes for Konka, 12 codes for Medion and 6 for Tevion. All the Tevion codes are common to Medion, but only 2 are common to all three. This suggests then that Tevion does equal Medion. Konka, however, might be a little more problematic.

As for the 3/4 digit codes, I'm a little at a loss. Perhaps there is a new breed of 4 digit Jumbos on the loose. Maybe I will buy that Maxim after all.
