Ingenico iSC 250 Screen Calibration

Ingenico iSC 250 PIN Pad

Some Ingenico iSC 250 PIN pads may experience touchscreen alignment problems which make signing with the pen or pressing buttons with your finger difficult. If you experience this, you may need to re-calibrate your screen.

Follow the instructions below to re-calibrate your iSC 250. 

1. Press and hold CLEAR and - (minus) simultaneously on the iSC250 payment terminal to reboot it.

If your iSC 250 is loaded with RBA 21 or above you no longer need to enter the 7581 code. Use +/- to select the Yes radio button and press ENTER instead.
