Introduction
Projector Features
A. Image Resolution
Fully compatible with true SVGA(63PA)/XGA(65PA), and supports SXGA using advanced intelligent
compression technology. The advanced intelligent compression technology enables it to present clear
compression SVGA/XGA images without line omission.
B. Brightness
Provides superior brightness using TI’s Digital Micromirror Device (DMD) and our own optical design,
with a geometric effect that increases light usage efficiency. By increasing the light usage efficiency we
can better reproduce the three basic colors (RGB) required for color reproduction on a single DMD.
C. Portability
This projector has a sophisticated shape, like that of an attaché case, with a retractable carrying handle
that is extremely compact and lightweight. It helps you make powerful presentations wherever you go
with its 5-pound weight and B5 size.
D. Keystone
The projection position is already set to the height of the line of vision; there is no keystone effect.
Even when projecting above or under the height of the line of vision, image distortion (if any) can be
adjusted using the hotkey “KEYSTONE” correction function.
E. Multilanguage
The OSD (On Screen Display: information screens and menus) in 7 languages (English, French,
German, Italian, Spanish, Simplified Chinese and Traditional Chinese) provides you with additional
information to help you make corrections with OSD operation in your native languages.
F. Auto Detect System
This projector can detect display signals from PCs with frequently used timing automatically or use
hotkey “AUTO” to do the optimization simultaneously. It does not require complicated adjustments
in order to project picture images from PCs.
G. Ceiling Mount and Rear Screen Projection
The projector is equipped with a full mirror scan conversion function (vertical/horizontal mirror),
which allows the image to be reversed for ceiling mounting as well as for rear projection applications.
H. AV box
An AV box is optional, and users can attach one or two to the projector. Additionally, our AV box
video standard is compatible with:
1

English 2
NTSC U.S. and Canada standard
PAL Western Europe standard
SECAM France and Eastern Europe standard
NTSC4.43 Middle East standard
If users want to watch CATV, AV box will serve the need.

Moving the Projector
Use the carrying handle when moving the projector.
Replace the lens cover and rotate the feet fully clockwise (to shorten the feet) when moving the
projector to prevent damage to the projector.
Caution
The carry bag (supplied) is intended to protect the projector from dust and scratches on the
surface of the cabinet. It is not designed to protect the projector from external shock.
Do not transport the projector in an unsuitable transport case by using a courier or transport
service. This may cause damage to the projector.

B. Replacing the Lamp
Replacing the lamp
When replacing the lamp, turn off the projector and unplug the AC cord. Wait 45 minutes so that
the lamp can cool. High-pressure lamp when hit, may explode if improperly handled.
Caution:
• Dispose of used lamps in accordance with local authorities.
• As the lamp is made of glass, do not apply shocks to it or scratch it.
• Also, do not use an old lamp, as this could cause the lamp to explode.
• If it seems that the lamp has exploded (for example, an explosive sound is heard),
disconnect the power cord from the outlet and ask your dealer to replace the
lamp. The lamp is covered by a front glass panel and an air-tight structure, but,
in rare cases, the reflector and the inside of the projector may be damaged by
scattered, broken pieces of glass, which could cause injury while being handled.
i. Turn the main power switch off and disconnect the power cord from the outlet.
ii. Remove the lamp cover.
• If hot, the lamp could cause burns. Wait for about 45 minutes until lamp has cooled down.
• Loosen a screw and remove the cover.
iii. Loosen the screw and pull the handle to remove the lamp.
• If the screw is not loosened completely, you could you’re your fingers.
• Do not insert your hand into the box after the lamp has been removed. (There are optical
parts inside that, if touched, could result in color unevenness, etc.)
iv. Replace the lamp with a new one and fix it using the same screw.
• Firmly tighten the lamp screw. Loose screws could result in a poor connection, which could
cause the unit to malfunction.
v. Install the lamp cover and fix it using a screw.
• To prevent burns, install the lamp cover and secure it using the screw.
• Do not turn on power with lamp cover removed.
• Whenever the lamp is replaced, reset the total operation time of the lamp. Do not reset if
the lamp has not been replaced.
• Do not reset the timer without changing the lamp, as this can cause the lamp to break.
