1.3 Projector Hazard Distances

For F90 series: WARNING. This may be a RG3 laser Product, dependent on which
lens used.
This projector may become Risk Group 3 (RG3) when an interchangeable lens with throw ratio greater than
3.15 is installed. For Northern America, installation requirements according to Risk group 3 (RG3) must be
followed when interchangeable lens with throw ratio greater than 2.33 is installed
Refer to the product manual for the lens list and throw ratio before operation.
Do not look directly in to the beam from the projector lens.
No direct eye exposure to the beam is permitted.
Operators shall control access to the beam within the hazard distance or install the product at a height that will
prevent eye exposure within the hazard distance.
See table below for a definition of hazardous distances versus the throw ratio of the lens.
For F70 Series: WARNING. This may be a RG3 laser Product, dependent on which
lens used.
This projector may become Risk Group 3 (RG3) when an interchangeable lens with throw ratio greater than
4.7 is installed. For Northern America, installation requirements according to Risk group 3 (RG3) must be
followed when interchangeable lens with throw ratio greater than 2.5 is installed
Refer to the product manual for the lens list and throw ratio before operation.
Do not look directly in to the beam from the projector lens.
No direct eye exposure to the beam is permitted.
Operators shall control access to the beam within the hazard distance or install the product at a height that will
prevent eye exposure within the hazard distance.
See table below for a definition of hazardous distances versus the throw ratio of the lens.

1.4 High Brightness Precautions

Restriction Zone (RZ) based on the HD (Hazard Distance).
The HD depends on the amount of lumens produced by the projector and the type of lens installed. See next
chapter"HD in function of the lens Throw Ratio (TR)", page 8 .
To protect untrained end users (as cinema visitors) the installation shall comply with the following installation
requirements: Operators shall control access to the beam within the hazard distance or install the product at
the height that will prevent spectators' eyes from being in the hazard distance. Radiation levels in excess of
the limits will not be permitted at any point less than 2.0 meter (SH) above any surface upon which persons
other than operators, performers, or employees are permitted to stand or less than 1.0 meter (SH) lateral
separation from any place where such persons are permitted to be. In non-cinema environments where
unrestrained behavior is reasonably foreseeable, the minimum separation height should be greater than or
equal to 3.0 meter to prevent potential exposure, for example by an individual sitting on another individual's
shoulders, within the HD.
