Important Information
Radiation Range of Emitted Light by the Projector (HD: Hazard Distance)
• The below table describes the radiation range of the MPE (Maximum Permissible Exposure) values of ANSI Z 136.1.
• Please keep within bounds for installing the projector.
Install a barrier for preventing human eyes or skin from entering irradiation area by laser radiation exceeding the MPE
values.
For the barrier installation position, keep over 1m as horizontal safety zone from the area exceeding the MPE values.
In case to install the projector over head, keep over 2.5m distance at least between the floor surface and the area exceed-
ing the MPE values.
• Avoid eyes or skin from exposing to direct or scattered emission exceeding the MPE values.
