WARNING: Do not look at the light emitted from the lens while the projector is being used.
As with any bright source, do not stare into the direct beam, RG2 IEC 62471‑5:2015.
WARNING: Do not enter the projection luminous flux using an optical device (such as magnifier or mirror).
Doing so can cause loss of sight.
f Strong light is emitted from the projector's lens. Do not look directly at this light.
rHazard 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.
While inside the hazard distance (within RG3 range), 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
distance (within RG2 range), it is considered to be safe in all circumstances except deliberately staring into the light
projected from the projector.

rRisk 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"). It is categorized as the risk group 3 when the hazard distance exceeds 1 m
(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 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.
The combination of the projector and the projection lens which the hazard distance exceeds 1 m (39‑3/8") and is
categorized as risk group 3 is as follows.
