NSM Grand Performer II Losing Memory
I have a customer who has an NSM Grand Performer II that loses memory
every time you cycle power. You can go through and reprogram everything to make it work, but as soon as power is cycled you are back to square one (P041 er 31 etc.). Any thoughts on what this could be or how to troubleshoot it further? I thought it might be a battery issue, but I could not find one. Any input and/or suggestions welcome. Thanks, Jim |

There is a timekeeperram on the cpu board. Inside this there is a battery.
Change the chip, og see this link http://www.automatenarchiv.de/wartung14.htm Regards Anders |

Change the chip, og see this link http://www.automatenarchiv.de/wartung14.htm Regards Anders This page is in German, but is pretty clear, you can also translate it with Alta-Vista's Babel-Fish web site. You can also replace the Dallas timekeeper IC with a socket and a newer one, otherwise carving the top off to replace the battery is a great idea!
