I am trying to freeplay a NSM Laser Disc wall hung. I think it's ES-5. I could only come up with a Firebird manual and tried to follow it's programming. I open door, pull service sw., program 094 h 200 h close door, but still shows 00 credits. I am missing something, but I don't know what. I think it should show 99 credits when done but never does.
I am sure it's operator error, but if somebody could bail me out it would be appreciated. I have never had a NSM before and this may be my last.
