Projector features / Preparations
Projector features
This projector has a capability to project various picture signals onto a screen. 
This projector requires only a minimal amount of space for installation and can 
produce a large projected image from even a short distance.
This projector also can give a benefit to mobile users and others by offering 
IEEE802.11g and IEEE802.11b wireless network and 10BASE-T/100BASE-
TX wired network communication and a special function named "PC-LESS 
Presentation". Even without PC, this projector realizes the display on screen, 
getting JPEG, Bitmap, PNG and MPEG4 from SD Memory Card or USB memory .
Preparations
Contents of  package
Please see the “Contents of package” in the “User’s Manual (concise)” which 
is a book. Your projector should come with the items shown there. Contact 
immediately your dealer if anything is missing.
NOTE  • Keep the original packing materials, for future reshipment. Be sure 
to use the original packing materials when moving the projector. Use special 
caution for the lens.
Replacing the filter cover for bottom-up use
For the projector installed bottom-up, please replace the filter cover with the 
enclosed filter cover for bottom-up use, to keep 
necessary ventilation space. 
Please refer to the “Air filter” (57) for how to 
detach and attach a filter cover.

WARNING  ►HOT! : Do not touch around the lamp cover and the exhaust 
vents during use or just after use, since it is too hot.
►Do not look into the lens or vents while the lamp is on, since the strong light 
is not good for your eyes. 
►Do not handle the elevator knobs without holding the projector, since the 
projector may drop down.
CAUTION  ►Maintain normal ventilation to prevent the projector from heating 
up. Do not cover, block or plug up the vents. Do not place anything that can stick or 
be sucked to the vents, around the intake vents. Clean the air filter periodically .
►Do not use the security slot to prevent the projector from falling down, since it 
is not designed for it.
►Use the shutdown switch only when the projector is not turned off by normal 
procedure, since pushing this switch stops operation of the projector without 
cooling it down.

Setting up
NOTE  • Be sure to read the manuals for devices before connecting them to the 
projector, and make sure that all the devices are suitable to be connected with this 
product. Before connecting to a PC, check the signal level, the signal timing, and the 
resolution.
-  Some signal may need an adapter to input this projector.
- 
 Some PCs have multiple screen display modes that may include some signals which 
are not supported by this projector. 
- 
 
Although the projector can display signals with resolution up to UXGA  (1600X1200), 
the signal will be converted to the projector’s panel resolution before being displayed. 
The best display performance will be achieved if the resolutions of the input signal and 
the projector panel are identical.
• While connecting, make sure that the shape of the cable's connector fits the port to 
connect with. And be sure to tighten the screws on connectors with screws.
• When connecting a laptop PC to the projector, be sure to activate the PC’s external 
RGB output. (Set the laptop PC to CRT display or to simultaneous LCD and CRT 
display.) For details on how this is done, please refer to the instruction manual of the 
corresponding laptop PC.
• When the picture resolution is changed on a pc depending on an input, automatic 
adjustment function may take some time and may not be completed. In this case, 
you may not be able to see a check box to select “Yes/No” for the new resolution on 
Windows. Then the resolution will go back to the original. It might be recommended to 
use other CRT or LCD monitors to change the resolution.
• In some cases, this projector may not display a proper picture or display any picture on 
screen. For example, automatic adjustment may not function correctly with some input 
signals. An input signal of composite sync or sync on G may confuse this projector, so 
the projector may not display a proper picture.
About Plug-and-Play capability
Plug-and-Play is a system composed of a PC, its operating system and peripheral 
equipment (i.e. display devices). This projector is VESA DDC 2B compatible. Plug-and-
Play can be used by connecting this projector to a pc that is VESA DDC (display data 
channel) compatible. 
• Take advantage of this feature by connecting an RGB cable to the COMPUTER IN 
port (DDC 2B compatible). Plug-and-Play may not work properly if any other type of 
connection is attempted.
• Please use the standard drivers in your pc as this projector is a Plug-and-Play monitor .

3. Slowly insert the SD card completely into 
the SD card slot. Make sure that the angled 
corner of the SD card is placed into the right 
side of the SD card slot, while inserting.
4. Replace the SD card slot cover. It is recommended that the cover is slid 
sideways to the projector.
Using the slot cover lock for security
