Risk Group 3 Information
yLight hazard warning
Failure to comply with the following may result in serious injury:
• No direct exposure to the beam is permitted, RG3 IEC 62471-5:2015.
• Operators control access to the beam within the hazard distance or install the projector at
sufcient height to prevent exposures of spectators’ eyes within the hazard distance.
The hazard distance is the distance measured from the projection lens at which the intensity or
energy per unit of surface is lower than the applicable exposure limit on the cornea or skin. If the
person is within the hazard distance, the beam is considered unsafe for exposure.
The hazard distance for this projector is 0-150 cm.
Note
This projector is an RG3 product, which must be installed in a safe place and must be handled by qualified and
professionally skill trained personnel
For the installation and removal of the lens, please consult your dealer with qualied profession-als to install it. Do not
try to install the projector yourself, otherwise your eyesight may be dam-aged
In case to install the projector over head, keep over 3m distance at least between the oor 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.
y
Caution:
Use of controls, adjustments or performance of procedures other than those specied herein may result in
hazardous laser light exposure.

• Ensure that the air intake vents do not recycle hot air from the exhaust vent.
• When operating in an enclosed space, make sure that the surrounding air temperature does
not exceed the projector's operating temperature and that the air intake and exhaust vents are
unobstructed.
• All enclosures should pass a certied thermal evaluation to ensure that the projector does
not recycle exhaust air. Recycling exhaust air may cause the projector to shutdown even if the
ambient temperature is within the acceptable operating temperature range.
