When you press a key on the system keyboard, the name of the key – for ex-
ample, ”INFO” – is displayed; the key number is displayed for function keys.

menu.
The following test images are displayed one after the other:

Authorization:
The status of the authorization input is displayed (0 = inactive, 1 = active),
