To retract the foot, hold up the projector while pressing the front adjuster button, then 
slowly lower the projector. Screw the rear adjuster foot in a reverse direction.
If the screen and the projector are not perpendicular to each other, the projected image 
becomes vertically trapezoidal. To correct this situation, adjust the value of Keystone in the 
Picture menu, on the projector control panel, or on the remote control.

Automatic keystone correction
Your projector is equipped with Autokeystone function that corrects keystoning 
automatically. See Autokeystone (On) on page 38 for details.
Selecting an application mode
The projector is preset with several predefined application modes so that you can choose 
one to suit your operating environment and input source picture type. To select a operation 
mode that suits your need, press the Mode (or MODE/SWAP) button. The application 
modes available for different types of signals are shown below. See Application Mode on 
page 38 for details.
Switching input signal
The projector can be connected to multiple devices 
at the same time. Howe ver, it can only display one at 
a time. To cycle through the available input sources, 
press the Source (or SOURCE/WIRELESS) button. 
A source selection menu will display at the center of 
the screen after you press the button.
The brightness level of the projected image will 
change accordingly when you switch between 
different input signals. Data (graphic) PC 
presentations using mostly static images are 
generally brighter than Video using mostly moving 
images (movies).
The input type affects the options available for the Application Mode. See Selecting an 
application mode on page 26 for details.
Hiding the image
In order to draw the audience’s full attention to the 
presenter, you can press the Blank (or BLANK /
5Up) button to hide the screen image. Press the

image automatically after a period of time when 
there is no action taken on the blank screen.
Do not block the projection lens from projecting as this could cause the blocking object to 
become heated and deformed or even cause a fire.

Using the w ireless functions
Your projector provides wireless connectivity that allows one or multiple wireless enabled 
client PCs to connect to the projector. The initial wireless connection process takes two 
steps:
• Prepare your computer for wireless connection. This includes installing Wireless 
Wizard and if necessary, configuring the wireless connection settings of your computer 
manually.
• Use Wireless Wizard to connect the computer to the projector.
When presenting via wireless connection, static screen images are captured on the computer 
and sent to the projector for display. This necessarily involves some processing power on the 
computer. Therefore, this format is unsuitable for movies and large animated graphics. They 
will appear jerky.
Refer to “Preparing your computer for wireless connection” below for more information.
About wireless connection modes and channels
Your projector is compatible with the three most popular wireless local area network 
(Wireless LAN or WLAN) standards defined by IEEE (Institute of Electrical and Electronics 
Engineers): 802.11 a, 802.11 b and 802.11 g. These standards are referred to in this manual 
as wireless connection modes.
The 802.11 b mode has a maximum raw data transfer rate of 11 Mbit per second (Mbps), 
while the 802.11 g mode has a faster speed of 54 Mbps, and is backward compatible with the 
802.11 b mode. The 802.11 a mode also allows 54 Mbps data transmission, but operates at a 
different band and is not backward compatible with the 802.11 b and 802.11 g modes. You 
need to use the MODE/SWAP button on the projector, or the SWAP button on the remote 
control to select a mode that matches that supported by the computer you want to connect.
In order to prevent interference when multiple wireless connections are used in close 
proximity, each wireless connection mode allows operation in different channels. For 
example, two 802.11 b networks can work simultaneously without interference under 
different channels. You can use the AU TO / C H . button on the projector, or the CH. button 
on the remote control to select a channel. Note that the channels that are available for use in 
a particular country differ according to the regulations of that country.
Hardware and software requirements
In order to display presentations using the wireless functions, check to make sure that your 
hardware and software satisfies the following requirements:
• Wireless LAN (WLAN or Wi-Fi) enabled computer (PC or Notebook)
• Operating system: Windows 2000 or XP (Home and Pro editions)
• CD drive (for installing Wireless Wizard)
