Call Attendant

[jthelman]

I purchased an IGT S2000 slot machine that had a “Call Attendant” error.  I then checked the voltage of the coin cell battery, and it was dead.  I then changed out the coin cell battery and removed the green Varta battery.  I turned the machine on, and it displayed “Call Attendant” I then opened the main door and went through the process of turning the jackpot reset key 4 times.
   Call Attendant
   Game Eprom CRC Mismatch -0xB0000001
   Non-Recoverable Data Error
   Some Critical Data Will Be Lost
   Press Test Switch For 2-3 Seconds
   Please Close the Main Door 
It again displayed “Call Attendant”, I then did a Ram Clear 224 chip and Key 45 chip and set the parameters and is working as it should but every time I turn off or unplug the machine and turn it back on, it then displays “Call Attendant”.  I then must open the main door and go through the process of turning the jackpot reset key 4 times every time I turn the machine on.

Check the voltage of the replacement battery. If its ok, I would try swapping the MPU board to see if the issue goes away.

Sending out MPU board for repair.
