Safety Information

The lightning ash with arrow head within an equilateral triangle is

intended to alert the user to the presence of uninsulated “dangerous volt-

age” within the product’s enclosure that may be of sufcient magnitude to

constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert
the user to the presence of important operating and maintenance (servic­ing) instructions in the literature accompanying the appliance.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT
EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. DANGEROUS HIGH
VOLTAGES ARE PRESENT INSIDE THE ENCLOSURE. DO NOT OPEN THE
CABINET. REFER SERVICING TO QUALIFIED PERSONNEL ONLY.

Class B emissions limits

This Class B digital apparatus meets all requirements of the Canadian
Interference-Causing Equipment Regulations.

Important Safety Instruction

1. Do not block any ventilation openings. To ensure reliable operation of the projector
and to protect from over heating, it is recommended to install the projector in a loca­tion that does not block ventilation. As an example, do not place the projector on a
crowded coffee table, sofa, bed, etc. Do not put the projector in an enclosure such
as a book case or a cabinet that restricts air ow.

2. Do not use the projector near water or moisture. To reduce the risk of re and/or
electric shock, do not expose the projector to rain or moisture.

3. Do not install near heat sources such as radiators, heaters, stoves or any other ap­paratus such as ampliers that emits heat.

4. Clean only with dry cloth.

5. Only use attachments/accessories specied by the manufacturer.

6. Do not use the unit if it has been physically damaged or abused. Physical damage/
abuse would be (but not limited to):

Unit has been dropped. -

Power supply cord or plug has been damaged. ­Liquid has been spilled on to the projector. ­Projector has been exposed to rain or moisture. -

Something has fallen in the projector or something is loose inside. ­Do not attempt to service the unit yourself. Opening or removing covers
may expose you to dangerous voltages or other hazards. Please call
Optoma before you send the unit for repair.

7. Do not let objects or liquids enter the projector. They may touch dangerous voltage
points and short out parts that could result in re or electric shock.

8. See projector enclosure for safety related markings.

9. The unit should only be repaired by appropriate service personnel.

Viewing 3D projection using the 3D function

IMPORTANT SAFETY INFORMATION. READ THE FOLLOWING WARN­INGS BEFORE YOU OR YOUR CHILD USE THE 3D FUNCTION.

Warning

Children and teenagers may be more susceptible to health issues 
associated with viewing in 3D and should be closely supervised
when viewing these images.

Photosensitive Seizure Warning and Other Health Risks

Some viewers may experience an epileptic seizure or stroke when 
exposed to certain ashing images or lights contained in certain
Projector pictures or video games. If you suffer from, or have a
family history of epilepsy or strokes, please consult with a medical

specialist before using the 3D function.

Even those without a personal or family history of epilepsy or 
stroke may have an undiagnosed condition that can cause photo­sensitive epileptic seizures.
Pregnant women, the elderly, sufferers of serious medical condi- 

English

Usage Notice

tions, those who are sleep deprived or under the inuence of
alcohol should avoid utilizing the unit’s 3D functionality.
If you experience any of the following symptoms, stop viewing 3D 
pictures immediately and consult a medical specialist: (1) altered
vision; (2) light-headedness; (3) dizziness; (4) involuntary move­ments such as eye or muscle twitching; (5) confusion; (6) nausea;
(7) loss of awareness; (8) convulsions; (9) cramps; and/ or (10)
disorientation. Children and teenagers may be more likely than
adults to experience these symptoms. Parents should monitor
their children and ask whether they are experiencing these symp­toms.
Watching 3D projection may also cause motion sickness, percep- 
tual after effects, disorientation, eye strain and decreased postural
stability. It is recommended that users take frequent breaks to
lessen the potential of these effects. If your eyes show signs of
fatigue or dryness or if you have any of the above symptoms, im­mediately discontinue use of this device and do not resume using
it for at least thirty minutes after the symptoms have subsided.
Watching 3D projection while sitting too close to the screen for 
an extended period of time may damage your eyesight. The
ideal viewing distance should be at least three times the screen
height. It is recommended that the viewer’s eyes are level with the

screen.

Watching 3D projection while wearing 3D glasses for an extended 
period of time may cause a headache or fatigue. If you experience
a headache, fatigue or dizziness, stop viewing the 3D projection

and rest.

Do not use the 3D glasses for any other purpose than for watch- 
ing 3D projection. Wearing the 3D glasses for any other purpose
(as general spectacles, sunglasses, protective goggles, etc.) may
be physically harmful to you and may weaken your eyesight.
Viewing in 3D projection may cause disorientation for some view- 
ers. Accordingly, DO NOT place your 3D PROJECTOR near open
stairwells, cables, balconies, or other objects that can be tripped
over, run into, knocked down, broken or fallen over.
