Front Panel LEDs
PWR LED
When the SHIFT key is used to adjust the display settings, the LED goes out. If one of the
other four keys is also pressed, the LED flashes until the limit of the adjustment range is
reached.
The following modes are also displayed:
■ Green light: Indicates ready status (Power ON)
■ Red light: Processor fan speed too slow or stopped
■ Red flashing: Unit overheating
Note: The overheating error signal has priority over fan errors and is
therefore displayed if both errors occur.
Note: To ensure that the user has noticed the error signal, the red
Overheating and Fan Speed LED signals can only be reset by
restarting the computer.

The operating console is provided with the analog TouchScreen with serial controller,
