The most hazardous threat posed by this 

product is the optical radiation known as 

Blue Light Hazard (400 nm to 780 nm). The 

thermal hazard threshold values are not clearly 

determined yet. 

The risk for the viewer depends on the use or 

on how the product is installed. However, there 

is no optical hazard as long as there is a limit 

on the time of exposure and the information 

contained in this instruction manual is observed. 

The aversion reactions are triggered by the 

exposure and they are a natural reaction that 

protects the eye from hazards through optical 

radiation. This includes in particular conscious 

aversion reactions such as eye or head 

movement (e.g. turning away). 

When using the product it is of particular 

importance to bear in mind that the aversion 

reactions of person at whom the light is directed 

at may be weakened or completely suspended 

as a result of medication, drugs or illness.

Because of the blinding effect of the product, 

improper use may lead to reversible, i.e. 

temporary impairment of sight (physiological 

blinding) or afterimages, or it may trigger 

queasiness and fatigue (through physiological 

blinding). The intensity of the temporary 

discomfort or the time until the side effects 

subside depends primarily on the brightness 

between the blinding-light source and the 

surrounding area. Photosensitive people in 

particular ought to consult a medical consultant 

prior to using this product. 

As a matter of principle the rule is that high-

intensity light sources carry a high secondary 

hazard potential due to their blinding effect. 

Just like looking into other bright light sources 

(e.g. headlights of a car), the temporary limited 

impairment of vision and afterimages may lead 

to irritation, inconveniences, impairments and 

even accidents, depending on the situation.

This information applies to the use of a single 

product. If more light-emitting products of 

the same type or of a different type are used 

together, the intensity of the optical radiation 

may increase. 

Every longer viewing/eye-contact with the 

source of radiation of this product by the user 

or other persons, with and without other light-

bundling instruments, is to be avoided as a 

matter of principle! Instead, the eyes are to be 

closed deliberately in such cases and the head 

ought to be turned away from the light beam. 

In case of a commercial use or the product’s use 

by public bodies, the user must be instructed to 

follow all applicable laws and regulations that 

correspond to the individual case of usage.

Do not aim the light beam directly into the eyes 

of a person. 

The user or any other person should not look 

directly into the light beam.

In the event of optical radiation hitting the eye, 

one must shut their eyes and turn their head 

away from the beam.

The instruction manual and this information 

must be stored safely and must always be kept 

together with the product. 

It is prohibited to look straight into the light that 

is being emitted by this product.
