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.
End of test:
If no key is pressed for 5 seconds, the test is aborted and you go back to the
menu.
The following test images are displayed one after the other:
1. Display light

Authorization:
The status of the authorization input is displayed (0 = inactive, 1 = active),
until some key or other is pressed.

A check determines whether the ASIC chip responsible for the SINEC L2-DP

message is issued.
