How can be accessed the QTERM-A7 SERVICE MENU

[RestaLG]

Sorry for my english...

manual says:

The service menu for the operator panel can be accessed before a project is downloaded, or by setting the mode switches in mode 1000. The location of the mode switches is described in the installation manual for the operator panel.

When I still have in operator panel downloaded project, i am not be able to access the service menu for calibrate touch screen, here is not any switches...

How I do it? thanks very lot.

Press and hold your finger on the screen while applying power. Hold you finger on it until the calibration screen appears. You can then follow the instructions on the screen.

Hello,
Is it possible to add a button to access to the calibrate touch or a c# code to enable this whithout to press the screen to the start.
best regards.
