*2: Height including protruding parts and legs: 73 mm (2-27/32˝).
*3: Operation range differs depending on the environment.
To use wireless functions, a PC is required that meets the condi-
tions given below:
OS: Windows XP Home Edition, Windows XP Professional,
Windows 2000 Professional, Windows Me (Millennium
Edition) or Windows 98SE (Second Edition)
CPU: Pentium III or higher, or other compatible processor (800
MHz or higher recommended when using the live mode;
1 GHz or higher is recommended when playing movies).
Memory: 128 MB or more (256 MB or more for Windows XP or
Windows 2000)
Free hard disk space:
60 MB or more
Hardware conditions:
CD-ROM drive (for software installation and viewing the
user’s manual).
An 802.11b/g built-in wireless LAN system or external
802.11b/g LAN card must be installed and running nor-
mally. However, some 802.11g/b wireless LAN may not
allow connection to 802.11g projectors. The data trans-
fer speed will be lower with an 802.11b LAN than that
with an 802.11g LAN.
Web browser:
Internet Explorer 6.0 or later, Netscape Communicator
7.0 or later
Direct X: DirectX® 8.1b or later must be installed.
Operation is not guaranteed for all computers that meet
the above conditions.
N OTES ON USE
• The projector uses a high-voltage mercury lamp that contains high
internal pressure. This lamp may break, emitting a large sound, or
fail to illuminate, due to impact or extended use. The length of
time that it takes for the lamp to break or fail to illuminate varies
greatly depending on individual lamp characteristics and usage
conditions.
• The brightness of the lamp will gradually decrease with use.
• The lamp, LCD panel, polarizing plate, and polarizing beam splitter
(PBS) are consumable parts. These parts may need to be replaced
during the guarantee period if the projector is used for six or
more hours per day.
• The replacement cycle of the LCD panel, polarizing plate, and
polarizing beam splitter (PBS) will be shortened if the projector is
subjected to continuous use for six or more hours. Likewise, the
replacement cycle of the lamp will be shortened if the power is
frequently turned on and off or the projector is subjected to con-
tinuous use for 10 or more hours.
• Interruptions may occur in the wireless connection due to signal
interference or PC conditions.
