IGT S3000 pinball touchscreen calibration

[Gasman]

Hi,
I'm new to slot machines.  I'm having problems with the touchscreen in the area where the denomination is changed.  I push on $5 and it takes it like the $10 was pushed.  I am finding that its acting as if its 1 space off to the right. 
If I hit the area to the right of the $10, I'll get the $10 selection.  Acting as if the touchscreen needs to be calibrated. Do I need the software for that?  And where might I find a service manual for this unit? Its  a IGT S3000 pinball slot.

Thanks,

Bob

Just open the door and turn the attendant key, that should let you enter the touchscreen calibration menu.
