IMPORTANT SAFETY INFORMATION
Important Safeguards
These safety instructions are to ensure the long life of the unit and to prevent fire and shock. Please read them
carefully and heed all warnings.
Installation
•
•
•
•
•
•
For best results, use the unit in a darkened room.
Place the unit on a flat, level surface in a dry area away from dust and moisture.
Do not place the unit in direct sunlight, near heaters or heat radiating appliances.
Exposure to direct sunlight, smoke or steam can harm internal components.
Handle the unit carefully. Dropping or jarring can damage internal components.
Do not place heavy objects on top of the unit.
Power Supply
•
•
•
The unit is designed to operate on a power supply of 100 - 240 V 50/60 Hz AC. Ensure that your power supply
fits these requirements before attempting to use the unit.
Handle the power cable carefully and avoid excessive bending. A damaged cord can cause electric shock or
fire.
Disconnect the power cable (main’s lead) from the power outlet after using the unit.
Before disconnecting the power cable, make sure that the STANDBY indicator lights in amber (not blinking or
in green).
Cleaning
•
•
Disconnect the power cable (main’s lead) from the unit.
Clean the cabinet of the unit periodically with a damp cloth. If heavily soiled, use a mild detergent. Never use
strong detergents or solvents such as alcohol or thinner.
•
•
Use a blower or lens paper to clean the lens, and be careful not to scratch or mar the lens.
Clean the ventilation slots and speaker grills on the unit periodically using a vacuum cleaner. If accumulated
dust blocks the ventilation slots, the unit will overheat, which may cause the unit to malfunction.
Use a soft brush attachment when using the vacuum cleaner. Do not use a hard attachment, such as a crevice
tool, to prevent the damage to the unit.
Lamp Replacement
•
Be sure to replace the lamp when the Status indicator comes on. If you continue to use the lamp after 1500
hours of usage, the lamp will turn off.
Fire and Shock Precautions
•
Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the buildup of heat inside
the unit. Allow at least 10 cm (3 inches) of space between the unit and walls.
•
Prevent foreign objects such as paper clips and bits of paper from falling into the unit. Do not attempt to retrieve
any objects that fell into the unit. Do not insert any metal objects such as a wire or screwdriver into the unit. If
something should fall into the unit, immediately disconnect the power cable from the unit and have the object
removed by a qualified PLUS service person.
•
Do not place any liquids on top of the unit.
Carrying around
When carrying the unit around, please use the carrying case that comes with it and, to protect the lens from
scratches, always shut the sliding lens cap. Also, do not subject the unit to strong mechanical shock.
Remove the wireless LAN card.
CAUTION – HOT!
The area around the exhaust vents is hot during and immediately after image projection.
To avoid burns, keep your hands away from this area.
Wait until the exhaust vents area cools off before touching it.
Do not look into the lens while the unit is on. Serious damage to your eyes could result.

Major Features
Ⅵ Ultra-light (1.6 kg), high brightness mobile projector with wireless, computer-less pre-
sentation function
The efficiency of the use of light is improved thanks to the combination of the DLP™ system and a unique optical design. The
three primary colors necessary for expressing colors (red, green and blue) are produced with a single DMD (an ultra-high
precision digital device), thereby achieving high brightness, compact size and light weight. In addition, wireless LAN technol-
ogy enables wireless presentations without the need to connect the projector to a computer using an RGB cable. The image
viewer function can be used to present PowerPoint files (including picture files and animations) stored on a CF card without
a computer.(*1)
*1. For details, refer to the “Image Viewer / Network” manual.
Ⅵ Sharp, clear picture
The DLP™ display system affords RGB color fidelity and inconspicuous gaps between the individual dots, thereby permitting
the display of small characters and diagrams with distinct clarity.
Ⅵ High contrast ration of 2000:1
Use of a new generation of DMD devices has given birth to an amazing 2000:1 high contrast ratio.
By widening the difference of brightness between black and white, you can see a degree of sharpness that is greater than just
the brightness based on specifications.
Ⅵ Great moving image playback capabilities using the same principles as DLP Cinema™
technology
Plus DLP type projectors have the same makings as the DLP Cinema™ technology used in movie theaters. Because of their
extremely fast response, even images with much movement – sports, movies – play smoothly without blurring.
Ⅵ Security lock function
The lock can be set so that a password must be input when the projector is started up. Without the correct password, no
operations other than turning the power on and off can be performed. This function effectively protects the projector from
unauthorized use.
Ⅵ Powerful functions for presentations
A wide variety of easy-to-set functions have been built into the projector, from a digital keystone correction function (used
when making settings) that corrects picture distortion, to an auto adjustment function that automatically identifies the PC
signal.
There is also a built-in “Presentation Timer” function for further presentation convenience.
Ⅵ Beautiful reproduction of high-quality images from DVD
Faithful reproduction of color tones gives rise to the display of natural images. High-quality images such as those from DVD
and digital high-definition television broadcasts bring out the display capabilities that are an essential strength of the DLP™
display system projector.
Ⅵ Digital/analog RGB input
by using a DVI cable to connect the projector with a personal computer equipped with a DVI connector. This will allow fully
digital pictures to be enjoyed.
Ⅵ Econo-mode switch function for the lamp output
Using the lamp Econo-mode will extend the life of the lamp and lower the power consumption.
By switching the lamp mode to suit your operating environment, you will save on lamp cost as well as contribute to energy
conservation and ecology.

Connecting Personal Computers and Video Equipment
Connecting this unit with a personal computer permits presentation data to be projected as a large screen display at
conferences, lectures, and on other occasions. Furthermore, connecting this unit to a DVD player or other video equip-
ment source in combination with an audio/video amplifier and speaker system will allow you to enjoy convincing home
theater.
Connections with Personal Computer
Please check the following before making connections with the personal computer.
•
A suitable resolution for the U4-237 is 1024
ן 768 dots (XGA) and the maximum displayable resolution is 1280 ן 1024 dots (S-XGA).
Make changes to a displayable resolution at the personal computer side. Please check with “Table of Supported Frequency”
on Page E-62.
•
•
The setting method for the personal computer will differ depending on the specific model. Please read the personal computer
instruction manual or the on-line help information, or contact the manufacturer of your personal computer.
Projection might not be possible when connection is with a personal computer that is equipped with a DVI-I connector such as
some PowerBook G4 computers and others when the signal is converted to analog RGB (which uses a mini D-sub 15-pin
connector) and connection is made with the pertinent equipment. In circumstances such as this, please purchase separately
a DVI-D cable and use the unit through the DVI connection.
Note that connections via DVI will enable the projection of a high quality image compared to connections using analog RGB.
Personal Computers with a DVI Connector
•
Make the connection with a DVI-D cable and the PC connector of the projector.
When connecting, arrange the connectors in the proper orientation and plug in. Turn the screw knobs and fasten to the
connector of the main unit.

Cleaning
• Be certain to disconnect the power plug from the power outlet before cleaning.
• Do not spray or otherwise expose the projector, lens, or screen to volatile substances such as insecticides. Do not leave rubber
or vinyl products in contact with the projector for long periods. Doing so could cause them to undergo qualitative changes or the
coatings may peel, etc.
Cleaning a Soiled Projector Main Unit
• Wipe with a lint-free, soft, dry cloth.
When very dirty, wipe with a cloth that has been moistened with a diluted neutral detergent, then finish with a dry cloth. If a
chemically-treated cloth is going to be used, please follow any written warnings.
• Do not wipe with thinner, benzene, or other solvents. Doing so could cause them to undergo qualitative changes or the coatings
may peel, etc.
• When removing the dust of the outflow and intake holes, use the brush attachment on a vacuum cleaner to clean out the dust.
Avoid using the vacuum directly without attaching the adapter as well as the use of a nozzle adapter.
• Do not scratch or otherwise hit the projector body with your nails or other hard object, since this will cause scratches.
Dirty Lens
• Clean using the same method you would use to clean a camera lens: Use a commercial blower for camera use or cleaning
paper for eye glasses. Be careful not to scratch the lens at this time.
Dust of the Intake and Outflow Holes
Dust that collects in the intake and outflow holes will obstruct the ventilation and cause the internal temperature to rise which
could cause damage. Clean this area carefully. As a guideline, clean at least every 100 hours of usage.
• Switch off the power, check that the STANDBY
indicator has changed to a steadily lit amber,
then unplug the power cable.
• Clean out the holes from the outside using a
vacuum cleaner. Use the brush adapter of the
vacuum cleaner to do this. Avoid using the

Replacing the Lamp Cartridge
• The lamp that is used as a light source in the projector has a limited service life. The rated service life of the lamp is
about 1500 hours (when used in normal mode only). This could be shortened depending on conditions of use and
other factors.
Note that lamp life will be extended when the projector is often used in Eco mode. (The rated service life of the lamp
means the average value of lamp life for lamps that have been manufactured over a long period, and it is derived from
test conditions at this company.)
• When the life of the lamp is exceeded, the STATUS indicator lights a steady red and the message [Replace the Lamp
Cartridge] is displayed on the screen. When this occurs, it is time to replace the lamp cartridge. Please make the
replacement following the procedure below.
• If the projector is used another 100 hours after the lamp’s service life is reached, the power is set to the standby mode
and no longer turns on.
• Contact a store that sells the U4-237 for a replacement lamp. Indicate you need a U4-150 replacement lamp for the
U4-232/U4-237 (order code 28-061).
CAUTION
• Replacement of the lamp cartridge is performed after switching off the power, waiting for the cooling fan to stop,
disconnecting the power plug from the power outlet, and then leaving the projector for about 60 minutes before
replacement is started. Replacement of the lamp cartridge during operation or immediately after operation stops will
cause burns because of the high temperature.
• Do not remove any screws other than those specified.
• Do not touch the lamp with bare hands. Doing so could shorten the life of the lamp.
• If lamp has reached the end of its usable life, the lamp bulb may shatter. When this happens, an explosive sound can
be heard and pieces of glass may be scattered in the lamp cartridge. Do not touch them as the pieces of glass may
cause injury. If this happens, contact your dealer or the store the projector was purchased.
