authorized specialist personnel in accordance with applicable regulations, after de-energizing the
power supply and with the machine switched off.
The machine must be safeguarded against reactivation.
Do not use any scratching or abrasive cleaning materials. The protective pane of the optical system
might get damaged.
The sensor requires no maintenance. Remove dirt build up from the optical system and the display at
regular intervals only with a soft, non-abrasive fabric. Residual dirt may have influence on the perfor-
mance and the accuracy of the sensor.
