I changed out the batteries on all of my pinball machines today and everything went well with the exception of my TOM which was the final machine. After changing out the batteries I went into the service menu to reset the Date/Time and everything is in German now.
I always change out my batteries with the machine on so as to not lose any game settings or high scores. I am pretty sure that I had the machine on while changing out my batteries on my TOM as well. My TOM has a remote battery holder.
Oh well, I am really looking for some advice on how to get my TOM to display the service menus in English again.
