r Hazard distance (IEC 62471-5:2015)
The distance from the projection lens surface, at which the level of exposure has reached the level of the
applicable Exposure Limit Value, is known as the hazard distance (HD) or safety distance.
Do not look into the projected light from inside the hazard distance (within RG3 range). The eyes may be damaged
by the direct irradiation. It is considered to be safe to look into the projected light from outside the hazard distance
(within RG2 range).

r Risk group
The combination of the projector and the projection lens is categorized as the risk group 2 when the hazard
distance is less than 1 m (39-3/8
(39-3/8
), and it 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 distance (within RG3 range).
In case of risk group 2, it can be used safely without damaging the eyes in any condition.
Combinations with any projection lens are categorized as risk group 3 for this projector.
Each dimension inside the hazard distance (within RG3 range) for combination with projection lens which the
hazard distance exceeds 1 m (39-3/8") is as follows.
