STA Validator Calibration
1)
Take a clean piece of white copier paper and cut it to the size of a bill (test bill).
2)
Set the switches on the side of the validator so that only #8, #7 and #1 are in the
ON position.
3)
Insert the paper. It should step in slowly (takes about 8-10 seconds).
4)
The validator will reject the paper. When you remove the paper from the validator,
the display should flash “11”. This means the process was completed.
5)
Turn all the switches back to the OFF position.
6)
IMPORTANT! Power down the validator for about 15 seconds. Then power it
back up and try a bill.
7)
Calibration complete.
