• Do not use 3D glasses for viewing any material other than 3D images.
• Before viewing 3D images, make sure to read the manuals provided with your 3D glasses and 3D
compatible content.
• Avoid viewing 3D images for a long period of time. Take a break of 15 minutes or longer after
every hour of viewing.
• If you feel sick while viewing 3D images, stop viewing them. If you continue to feel sick, consult a
doctor.
6
• When viewing 3D images in a room where an LED lighting system or fluorescent lights are used,
you may feel that the light in the room flickers. If this is the case, dim the lights until you do not
notice any flickers, or turn off the lights.
• If you or any member of your family has a history of light-sensitive seizures, consult a doctor before
viewing 3D images.
• To view 3D images, sit in front of the screen so that your eyes are parallel and level with the screen.
• Viewing 3D images from a place that is too close to the screen may result in eye strain. The
distance between the screen and you should be at least three times the height of the screen.
• Adult supervision is required for children using 3D glasses.
• Viewing 3D images is not recommended for children under 6 years old. It may negatively affect
development of their vision. Consult a doctor before using 3D glasses.

1. Preparations for Using the Projector
This chapter explains the names and functions of the different parts of the projector and remote control,
and how to use them. It also explains how to position the projector and how to connect it to other
equipment.
Precautions for Using the Projector
• If metal objects, or water or other fluids fall inside this machine, you must turn off its power
immediately. After turning off the power, be sure to disconnect the power cord plug from the wall
outlet. Then contact your service representative and report the problem. Do not use the machine.
Doing so could result in fire or electric shock.
• Do not use any power sources other than those that match the specifications shown. Doing so
could result in fire or electric shock.
• The supplied power cord is for use with this machine only. Do not use it with other appliances.
Doing so could result in fire or electric shock.
• It is dangerous to handle the power cord plug with wet hands. Doing so could result in electric
shock.
• Do not place the power cord and connection cable in front of the lens or exhaust vents when the
product is turned on. Doing so may result in fire.
• Be sure to locate the machine as close as possible to a wall outlet. This will allow easy
disconnection of the power cord in the event of an emergency.
• Do not look into the lens or vent when the machine is on. The bright light may damage your eyes.
Be especially careful in an environment with children.
• Do not use flammable sprays or solvents in the vicinity of this machine. Also, avoid placing these
items in the vicinity of this machine. Doing so could result in fire or electric shock.
• Do not place low heat resistant material near the exhaust vents. Hot air may come from the
exhaust vents, resulting in damage to the machine or an accident.
• Do not place the power cord and connection cable in a way that might cause someone to trip
and fall. The machine might fall over and cause an injury.
11
1. Preparations for Using the Projector
• Push the power plug all the way into the power outlet. Do not use a power outlet with a loose
connection. Doing so may result in heat buildup. Plug the power cord in the correct direction into
the base. If they are not plugged in correctly, it could result in smoke, fire, or electric shock.
• When disconnecting the power cord from the wall outlet, always pull the plug, not the cord.
Pulling the cord can damage the power cord. Use of damaged power cords could result in fire
or electric shock.
• Do not block the projection light when it is on. If you do so, the part that is blocking the projection
light may get quite hot and deform, deteriorate or cause a burn or fire. The reflected light may
make the lens hot and cause a machine failure. To temporarily suspend projection, select the AV
mute function. To suspend longer, turn off the machine.
• Do not increase the volume unless you are listening while increasing the volume. Also, lower the
volume before turning off the power, because a loud sound may be emitted when the power is
turned on and cause hearing damage.
• Do not tilt the machine horizontally more than ±20 degrees. Doing so may cause the entrance of
foreign objects in the housing of the machine which could result in fire or electric shock.
• Power Source
• (mainly Europe and Asia)
220–240 V, 1.7 A or more, 50/60Hz
• (mainly North America)

Positioning the Projector
When positioning the projector, place it so that the projector's lens faces the screen. Make sure the
projector and the screen are parallel to each other.
Adjust the distance between the projector and the screen according to the size of the projected image.
For details, see page 29 "Relationship Between the Projection Distance and the Screen Size".
• The projector can be installed at any vertical angle. However, the projector cannot be tilted to the
left or right. Do not use the projector horizontally inclined (±20 degrees or greater).
• When the projector is installed on a ceiling with the lens-down, be sure to press the [Power] button
and wait until the projector cooling process completes before disconnecting the power cord.
Otherwise, you cannot turn the projector back on for up to approximately 25 minutes because it
needs to release the internal heat.
• When installing the projector lens-up, be sure to secure the projector to the wall or ceiling using
brackets.
