1.5.1 Safety of Laser Light
0019-9500
Laser light can be extremely hazardous to the human body.
The machines laser scanning system is contained in a protective housing and external covers to prevent escape of laser light outside the machine. In other words,
the user is free of laser-related hazards as long as the machine is being used for its intended purposes.
The following warnings are given to comply with Safety Principles (EN60950).
Laserstrahlen können für den menschlichen Körper gefährlich sein. Aus diesem Grund ist das optische Lasersystem mit einem Schutzgehäuse und einer Außenab-
deckung dicht verschlossen und hat eine Struktur, die keine Laserstrahlen nach außen dringen lässt. Unter der Voraussetzung, dass der Benutzer dieses Gerät normal
bedient, ist ein Austritt von Laserstrahlen daher ausgeschlossen.
