Calibrating the Ingenico iSC250 Touchscreen

Sometimes, the Ingenico iSC250’s touchscreen can perform differently than the end user expects. For example, the Ingenico might:

• Register a cancel instead of an okay button press
• Clear signature when the user has not selected the clear button
• Appear to write without the stylus

Follow these steps to recalibrate the iSC250’s touchscreen:

1. Press and hold the [Clear] and [-] (minus) keys simultaneously on the iSC250 payment terminal to reboot it
2. When the iSC250 reboots and the grey Retail Base screen appears, press [2], [6], [3], [4], and the [Enter] key
3. The Press + for menu screen appears, press the [+] (plus) key to display the functions menu
   NOTE: If you do not see the Press + for menu screen, restart from step 1
4. Select Telium Manager > Initialization > Hardware > Calibration to display the Calibration screen.
