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
䡵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.
䡵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.
䡵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.
䡵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.
䡵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.
䡵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.
䡵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.
䡵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.
䡵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.
