Important Information

Remote Control Precautions

• Handle the remote control carefully.

• If the remote control gets wet, wipe it dry immediately.

• Avoid excessive heat and humidity.

• Do not short, heat, or take apart batteries.

• Do not throw batteries into re.

• If you will not be using the remote control for a long time, remove the batteries.

• Ensure that you have the batteries’ polarity (+/–) aligned correctly.

• Do not use new and old batteries together, or use different types of batteries together.

• Dispose of used batteries according to your local regulations.

Lamp Replacement

• To replace the lamp, follow all instructions provided on pages 61-62.

• 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.

A Lamp Characteristic

The projector has a high-pressure mercury lamp as a light source.

A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly turning the

lamp on and off will increase the possibility of its lower brightness.

CAUTION:

• DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the

projector off and then disconnect the power cord. Allow at least one hour for the lamp to cool before

handling.

• When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projec-

tor. Glass fragments could fall if the lamp has been burned out.

Note for US Residents

The lamp in this product contains mercury. Please dispose according to Local, State or Federal Laws.

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 LCD shutter eyeglasses or your 3D compatible content such as DVDs, video games, com-

puter’s video les and the like.

To avoid any adverse symptoms, heed the following:

- Do not use LCD shutter 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 doc-

tor.
