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 of fering 
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 .

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

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.
-   Be sure to consult to the administrator of the network. Do not connect  LAN port to any 
network that might have the excessive voltage.
-   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 .

Setting up
Using a USB storage
In order to view images stored in a USB storage, such as a USB memory, insert 
the device into the USB STORAGE port.
Before removing the USB storage, be sure to perform the REMOVE procedure 
using the SERVICE menu under the MIU menu  (
59).
NOTE  • 
When using the projector with a wired LAN, please remove the wireless network card.
IMPORTANT NOTE  • To comply with FCC RF exposure compliance requirements, the antenna 
used for this transmitter must be installed to provide a separation distance of at least 20 cm from all 
persons and must not be collocated or operating in conjunction with any other antenna or transmitter .
• When using wireless network card, please make sure to put the SD card slot cover 
onto projector top case to protect the card from electrostatic discharge influence.
Using an SD card
In order to view images in an SD Memory Card (SD 
card), insert the card into the SD card slot. If the 
wireless network function is required, load the internal 
clock battery 
(64) and insert the enclosed Wireless 
network card (SD card) in to the SD card slot.
Inserting an SD card
1. Make sure that the power code is not 
plugged into the projector.
2. Remove the SD card slot cover. It might be recommended 
to hook the edge of its side face up to remove it. 
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
Using the enclosed slot cover lock can prevent the SD card slot cover from being opened.
1. Open the two plates of the slot cover lock to put the tips of two plates 
together, and then insert the tips to the lock hole of the SD card slot cover.
2. Put the body of the two plates together. Then, hook a padlock or combination 
lock to the hole of the slot cover lock.
Removing the SD card
When removing “wireless network card“, turn the projector off and unplug the
