Note
Temperature range for display
To increase the service life of the display, the display switches itself off when the permitted
operating temperature is exceeded. When the display cools down again, it automatically
switches itself on again. When the display
is switched off, the LEDs continue to show the
status of the CPU.
For more information on the temperatures at which the display switches itself on and off,
refer to the
Technical specifications (Page 36).
