Hitachi Seiki 20SII switched to metric after changing battery

Does anyone know how to change from metric back to English. I changer the battery and now it is displaying metric. I can run the program with a G20 but it switches back to metric when the program is finished. It has a Seicos control. Any help would be greatly appreciated.

Hello!
can you confirm the control - assuming Seicos II? Could be Seicos III but not too many HT20SII with Seicos III out there
