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).

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
"
). 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 case of risk group 2, it can be used safely without damaging the eyes in any condition.
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.
Model No. Projection lens Model No. Use condition Risk group

PT-MZ10K *3 ET-EMT800 *1
When the throw ratio is 4.6:1 or less Risk group 2
When the throw ratio exceeds 4.6:1 Risk group 3
*1 The risk group varies depending on the throw ratio of the actual use condition.
*2 When PT-MZ16K or PT-MZ13K is used with the optional Zoom Lens (Model No.: ET-EMT800) attached, the hazard distance
exceeds 1 m (39-3/8") and therefore it is categorized as the risk group 3.
*3 When PT-MZ10K is used with the optional Zoom Lens (Model No.: ET-EMT700) attached, the hazard distance is less than 1 m
(39-3/8") and therefore it is categorized as the risk group 2.
