r Hazard distance (IEC/EN 62471-5:2015)
The distance from the projection lens surface, at which the emission reaches the Accessible Emission Limit (AEL)
of risk group 2, is known as the hazard distance (HD) or safety distance. The area where the emission exceeds
the Accessible Emission Limit of risk group 2 is called the hazard zone (HZ).
Within the hazard zone, never look into the light projected from the projector. The eyes may be damaged by direct
irradiation even if you look at the light just for a moment. If you are outside the hazard zone, it is considered to be
safe in all circumstances except deliberately staring into the light projected from the projector.

r Risk group
The combination of the projector and the projection lens is categorized as risk group 2 when the hazard distance
is 1 m (39-3/8") or less. It is categorized as risk group 3 when the hazard distance exceeds 1 m (39-3/8
will be for professional use instead of consumer use.
In case of risk group 3, there is a possibility of damaging the eyes by direct irradiation when looking into the
projection light from inside the hazard zone even for a moment.
In the case of risk group 2, safe use without damaging the eyes is possible in all circumstances except deliberately
staring into the light projected from the projector.
Combinations with any projection lens are categorized as risk group 3 for this projector.
Each dimension inside the hazard zone for combination with projection lens which the hazard distance exceeds
1 m (39-3/8") is as follows.

Note
f The value in the table is based on IEC/EN 62471-5:2015.

Attention
f If the light projected from the projector directly enters the eyes while you are inside the hazard zone, the retinas may be
damaged. Do not enter the hazard zone during use. Alternatively, install the projector in a location where the projected light
will not directly enter the eyes.
