NSM Prestige II EAROM ER-1400

I've tried my best to follow the manual but can't manage to program this thing.  If possible, all I (might) really need is to set it for 80 records and free play.  I go through the process but it doesn't seem to work.  I managed to mess up the first one, I think I programmed the "secret" code and locked myself out. Luckily I bought 3 so I'm on number 2.

Is there a way to clear them without a programmer or whatever?

Do I have to start at the beginning and set a value for each command in order for the free play to work.  With the original earom it was scanning but not counting as it scanned.  I have two control units and if I put the good earom in, it will work perfectly. (luckily they are in a socket)  I do very little work on NSMs, all I've ever had is mech problems but fixed those.
