7 Touch Screen
The touch screen is to be operated with a finger or with the included touch sty-
lus. Never use sharp objects, such as a screwdriver, for operating the touch
screen.
The touch screen is already calibrated when the M70 is delivered.
If a recalibration is required for any reason (humidity of air, temperature, etc.),
turn the key to the left, and follow the instructions on displayed on the screen.
It is also possible to use the Service Menu for calibration. See section 8.2 Service
Menu .
7.1 Screen Saver
To extend the lifetime of the background lighting the screen saver is activated
after 15 minutes.
It is possible to set a different screen saver activation time, or to disable it, under
Setup/Terminal Options in the configuration tool for the operator panels.
Note:
The screen saver does not make the screen totally dark; it is still possible to see
objects on the screen. When the screen saver is activated, the screen has to be
touched once in order to inactivate the screen saver and to receive operator input.
Note:
The Dim back register (available from Setup/System Signals in the configuration
tool for the operator panels) cannot make the display of the M70 totally dimmed.
