This is the error message exactly as it appears on the screen:

There are now 2 versions of the Ingenico 3070 pinpad. The older version has a serial number that contains an SS in the middle of the serial number. The newer pinpad with the updated firmware in it is designated by a GS in the middle of the serial number. The old revision will work with the standard Ingenico 3070 setting in the Setup Wizard. The new pinpads will not. For the new pinpads to work they need to be set to Ingenico 3070 New Prompts. If you do not see that option displayed, then you need to upgrade System Five to version 220.127.116.11 or higher.
