Page 1 of RF modulation help needed with Medion MD4310

Does anyone know how I can change the RF modulation on this unit, as I currently suffer with co-channel intereference with a terrestrial signal. There is no adjustment screw on the rear of the unit, so I assume it is done electronically, but there is no mention of how to do it in the manual, and an email to Medion themselves got no results (but then they prolly know as much about the machine as I do lol) It has been suggested to me that this is probably in a service menu hidden away somewhere - anyone know how to access it? Any help would be very much appreciated.
