NOTE
Temperature range for display
To increase its service life, the display switches off at a temperature below the permitted
operating temperature of the device. When the display cools down, it automatically switches
itself on again. When the display is switched off, the LEDs continue to show the status of the
CPU.
You can find additional information on the temperatures at which the display switches itself
on and off in the Technical specifications (Page 35).
