A while ago, I entered the service mode on my Sharp DR470 (called DR7 in some regions), messed around with it and now I am only getting an Er-MD80 error when trying to turn the unit on.
Somebody with a DR470 kindly agreed to check what the original settings were, so I can reset them, but I forgot how to actually get into service mode on this MD portable. I seem to remember that I had to use a remote control from a different unit (my MT831), but I tried it this morning and the DR470 just wouldn't react to anything that I press on the MT831's remote, so maybe I remember that wrong.
Does anybody now how to enter the service mode on Sharp portables that don't have a 'Sync/Enter' button?
Any help would be greatly appreciated! Thanks!
