Warning sign
Meaning
The warning sign is located on the back of the device and
indicates that the device is equipped with a class 3R laser.
The power is less than 1.5-3 mW. The frequency range of the
laser is at 780 nm.
Do not look directly into the laser beam or the opening
from which the laser beam emerges!
Residual risks
Warning of electrical voltage
There is a risk of a short-circuit due to liquids penetrating the
housing!
Do not immerse the device and the accessories in water. Make
sure that no water or other liquids can enter the housing.
Warning of electrical voltage
Work on the electrical components must only be carried out by an
authorised specialist company!
Warning of explosive substances
Do not expose the batteries to temperatures above 60 °C! Do not
let the batteries come into contact with water or fire! Avoid direct
sunlight and moisture. There is a risk of explosion!
Warning of laser radiation
Laser class 3R, P max.: < 1.5–3 mW, λ: 780 nm,
EN 60825-1:2014
Do not look directly into the laser beam or the opening from which
it emerges.
Never point the laser beam at people, animals or reflective
surfaces. Even brief eye contact can lead to eye damage.
Examining the laser output aperture by use of optical instruments
(e.g. magnifying glass, magnifiers and the like) entails the risk of
eye damage.
When working with a laser of class 3R, observe the national
regulations on wearing eye protection.
