Important Information
Important safeguards
These safety instructions are to ensure the long life of your projector and to prevent fire, shock,
damage and injury. Please read them carefully and heed all warnings.
Laser precautions
This product is classified as Class 3R of IEC60825-1 and 21 CFR Part 1040.10 Safety Standards.
CLASS 3R LASER PRODUCT
This Laser Product is designated as Class 3R during all procedures of operation.
LASER LIGHT - AVOID DIRECT EYE EXPOSURE.
Do not point laser or allow laser light to be directed or reected toward other people or reective
objects.
Direct or scattered light can be hazardous to eyes and skin.
There is a potential hazard of eye exposure to laser radiation if the included instructions are not
followed.
Caution – use of controls or adjustments or performance of procedures other than those specied
herein may result in hazardous radiation exposure.
Class 2 range. Class 3R laser product, per IEC 60825-1, has limited risk of laser hazard and is safe
for non-intrabeam viewing. It is recommended to keep the audience 100 cm away from the exit plane
of the lens hood and reduce the laser hazard to a much safer class 2.
Non-laser emission. There remains non-laser emission from the projection lens. This portion of
emission has been tested per IEC/EN 62471 to be Risk Group 1 (Low Risk).
General precautions
This is a Class A product. It has been tested and found to comply with the limits for a Class
A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a commercial
environment.
Operation of this equipment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own expense.
In order to reduce any interference with radio and television reception, use a signal cable with ferrite
core attached. Use of signal cables without a ferrite core attached may cause interference with radio
and television reception.
CAUTION
No eyewear is required for unintentional viewing.
Avoid staring into visible beams.

Installation and handling
HEALTH PRECAUTIONS TO USERS VIEWING 3D IMAGES
Before viewing, be sure to read health care precautions that may be found in the user’s manual
included with your 3D eyeglasses or your 3D compatible content such as Blu-ray Discs, video
games, computer’s video  les and the like.
To avoid any adverse symptoms, heed the following:
• Do not use 3D eyeglasses for viewing any material other than 3D images.
• Allow a distance of 2 m/7 feet or greater between the screen and a user. Viewing 3D images
from too close a distance can strain your eyes.
• Avoid viewing 3D images for a prolonged period of time. Take a break of 15 minutes or longer
after every hour of viewing.
• If you or any member of your family has a history of light-sensitive seizures, consult a doctor
before viewing 3D images.
• While viewing 3D images, if you get sick such as nausea, dizziness, queasiness, headache,
eyestrain, blurry vision, convulsions, and numbness, stop viewing them. If symptoms still
persist, consult a doctor.
• View 3D images from the front of the screen. Viewing from an angle may cause fatigue or
eyestrain.
The projector must be installed only by suitably qualied personnel, in accordance with local
building codes.
Consult your dealer for information about transporting and installing the projector. Do not
attempt to transport and install the projector yourself. The projector must be installed by qualied
technicians in order to ensure proper operation and reduce the risk of bodily injury.
Do not point the projection beam toward other people or reective objects.
The projector should be installed as close to the power outlet as possible.
The power connection should be easily accessible, so that it can be disconnected in an emergency.
Place the projector on a at, level surface in a dry area away from dust and moisture. Tilting the
front of the projector up or down from level could reduce laser life. Do not put the projector on its
side when the laser is on. Doing so may cause damage to the projector.
