Important Information
Laser radiation range/No entry range (HD:Hazard distance)
• The below table describes the radiation range of emitted light by the projector that is classified as Risk Group 3
(RG3) in the IEC 62471-5 First edition 2015.
• The below table describes the radiation range of emitted light by the projector that is classified as Risk Group 3
(RG3) in the IEC 62471:2006 (for USA).
• Please keep within bounds for installing the projector.
Install a barrier for preventing human eyes from entering the RG3 area. For the barrier installation position, keep
horizontal safety zone over 2.5m from the RG3 area. In case to install the projector over head, keep over 3m dis-
tance at least between the floor surface and the RG3 area.
Operators shall control access to the beam within the hazard distance or install the product at the height that will
prevent exposures of spectators’ eyes within the hazard distance.
