2. Place the projector on a flat, level surface in a dry area away from dust and moisture.

To avoid premature lamp failure, do not tilt the front of the projector up or down by more than 15^ from level.

1. Do not place your projector in direct sunlight, near heaters or heat radiating appliances.
2. Exposure to direct sunlight, smoke or steam can harm internal components.
3. Handle your projector carefully. Dropping or jarring can damage internal components.
4. Do not place heavy objects on top of the projector.
5. If you wish to have the projector installed on the ceiling:

a. Do not attempt to install the projector yourself.
b. The projector must be installed by qualified technicians in order to ensure proper operation and reduce the risk of bodily injury.
c. In addition, the ceiling must be strong enough to support the projector and the installation must be in accordance with any local building codes.
d. Please consult your dealer for more information.

Fire and Shock Precautions

1. Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your projector. Allow at least 4 inches (10 cm) of space between your projector and a wall.
2. Prevent foreign objects such as paper clips and bits of paper from falling into your projector.

Do not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified service personnel.

1. Do not place any liquids on top of your projector.
2. Do not look into the lens while the projector is on. Serious damage to your eyes could result.
3. 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.
4. Do not cover the lens with the supplied lens cap or equivalent while the projector is on. Doing so can lead to melting of the cap and possibly burning your hands due to the heat emitted from the light output.
5. Do not place any objects, which are easily affected by heat, in front of the projector lens or a projector exhaust vent. Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the light output and exhaust.
6. The projector is designed to operate on a power supply of 100-240 V 50/60 Hz AC. Ensure that your power supply fits this requirement before attempting to use your projector.
7. Handle the power cable carefully and avoid excessive bending. A damaged cord can cause electric shock or fire.
8. If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet.
9. Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.
10. Do not handle the power plug with wet hands.

CAUTION

1. Do not try to touch the ventilation outlet on the right and rear side (when seen from the front) as it can become heated while the projector is turned on.
2. Do not use the tilt-foot for purposes other than originally intended. Misuses such as gripping the tilt-foot or hanging on the wall can cause damage to the projector.

Before putting the projector in the soft case, be sure to retract the feet. Failure to do so may cause damage to the projector.

1. When carrying the projector, heed the following:

2. Ensure that the power cable and any other cables are disconnected before moving the projector.

3. Cover the lens with the supplied lens cap so as not to scratch the lens surface.

4. Do not send the projector in the soft case by parcel delivery service or cargo shipment. The projector inside the soft case could be damaged.

5. Select "High" in the Fan mode if you continue to use the projector for consecutive days. (From the menu, select [Advanced] [Fan Mode] [High].)
6. Do not unplug the power cable from the wall outlet under any one of the following circumstances.

Doing so can cause damage to the projector:

• While the projector is turned on.

• While the cooling fans are running. (The cooling fans continue to work for 60 seconds after the projector is turned off).

• If you accidentally turn off the main power by disconnecting the power cable or press the main power switch during cooling down, wait 10 minutes and then turn on the projector to resume. This is to protect the lamp.

Lamp Replacement

To replace the lamp, follow all instructions provided on page E-44.
- Be sure to replace the lamp when the message "The lamp has reached the end of its usable life. Please replace the lamp." appears. If you continue to use the lamp after the lamp has reached the end of its usable life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury.

If this happens, contact your dealer for lamp replacement.

• Allow a minimum of 60 seconds to elapse after turning off the projector. Then turn off the main power switch, disconnect the power cable and allow 60 minutes to cool the projector before replacing the lamp.

To turn on the main power to the projector, press the Main Power switch to the on (I) position.

The POWER indicator will light orange.

Before you turn on your projector, ensure that the computer or video source is turned on and that your lens cap is removed.

Only after you press the ON/STAND BY button on the projector cabinet or POWER ON button on the remote control for a minimum of 2 seconds will the POWER indicator turn to green and the projector become ready to use.

See page E-48 for more details.

NOTE: The POWER and STATUS (LED) indicators blinking green at the same time indicates the main power was interrupted during previous operation. Wait for 60 seconds (cooling period) to see if the lamp turns on by itself.

Note on Startup screen (Menu Language Select screen)

When you first turn on the projector, you will get the Startup screen. This screen gives you the opportunity to select one of the 9 menu languages.
