S2000 Change Denomination

[multitec]

Question for the experience tech:

Having an issue changing the S2000 denomination from 1.00 to any value.

Tried a key 31. Results > Allows me to enter 7.1.1Key Chip Config.
Does not allow the 1.00 value to be changed to any value. All button lights go off at this point.
It does Allow me to change other option, like printer, coin -in and so on.

Note: No credits on the machine prior to key chip 31.
Board 502 Super Stepper.
Machine build date 12-02-2003
Upright / 3-coin / 3 Reel

Try to avoid a Clear Key.
Any suggestions appreciated,

What value are you trying to go to?
Anything less than $1.00 Will require a clear key to reset the accounting value to less than a dollar.

OK, Thanks, Is 97 the correct clear key for this board?

[qbert]

Clear 97 will work fine for your board
