edition 2014. This product is classified as RG3 of IEC/EN 
62471-5 First edition 2015.
Obey the laws and regulations of your country in relation to 
the installation and management of the device.

 CAUTION

Use of controls or adjustments of procedures other than 
those specified herein may lead to hazardous laser radi-
ation exposure.

•  No direct exposure to the beam shall be permitted, RG3 

IEC/EN 62471-5:2015.

•   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.

•  Do not look at operating light source. Eye injury may 

result.

•  Not for household use. (for USA)
•  This projector must be installed high enough to provide 

clearance for people who may walk beneath the beam 
path or hazard distance. (for USA)

•  Direct exposure of human eyes to beam is prohibited.
•  The following graphic symbol indicating that looking into 

the projector is prohibited is displayed on the projector 
cabinet.

•  Do not allow to look into the projector beam at any dis-

tance from the projector. An adult should supervise the 
children to prevent exposure risks.

•  Check that there is no one looking at the lens, when 

using the remote control for starting the projector.

•  Do not look at the projected light using optical devices 

(binoculars, telescopes, magnifying glasses, reflectors, 
etc). Doing so could result in vision impairment.

•  When performing the lens shift adjustment, make sure 

that you are behind or beside the projector. Doing so from 
the front of the projector may cause intense light to enter 
into your eyes, resulting in damage to them.

•  [WARNING: MOUNT ABOVE THE HEADS OF CHILDREN.] 

The use of a ceiling mount is recommended with this 
product to place it above the eyes of children.

•  This projector, which is an RG3 product, is for business 

use and must be installed in location where safety is 
assured. For this reason, installation of the projector and 
mounting and removal of the lens unit must be performed 
by professional service personnel. To do the works, be 
sure to consult your dealer. NEVER install the projector 
by end users. Doing so may cause visual impairment and 
other injuries.

•  Keep any items such as magnifying glass out of the light 

path of the projector. The light being projected from the 
lens is extensive, therefore any kind of abnormal objects 
that can redirect light coming out of the lens, can cause 
unpredictable outcome such as fire or injury to the eyes.

•  When turning on the projector, ensure that nobody is fac-

ing towards the lens in the path of the light emitted from 
the laser.
