 If you continue to use the lamp after this period, the possibility of the 
lamp breaking becomes greater. When the lamp replacement 
message appears, replace the lamp with a new one as soon as 
possible, even if it is still working.
 Depending on the characteristics of the lamp and on the way it has 
been used, the lamp may become darker or stop working before the 
lamp warning message appears. You should always have a spare 
lamp ready in case it is needed.
 Contact your dealer for a spare lamp.

down period has ended and a pip-pip confirmation 
buzzer sounds, and then disconnect the power cable.
The cool-down period lasts for about 20 seconds.

Replacing the Lamp
CAUTION
 If you are replacing the lamp because it has stopped working, it is 
possible that the lamp is broken.
If replacing the lamp of a projector which has been installed on the 
ceiling, you should always assume that the lamp is broken and 
handle it with extreme care during removal. Furthermore, you 
should stand to the side of the projector, not underneath it.
 Wait until the lamp has cooled down sufficiently before removing the 
lamp cover. It takes a further one hour after the cool-down
g period 
has finished for the lamp to be cool enough.

User’s Guide
GlossaryThe following is an explanation of some of the terms used in this guide which may be unfamiliar or which are not explained in the text of this guide itself. Further 
information can be obtained by referring to other commercially-available publications.
5BNC
A port used to input analogue video signals.
Abs. Color Temp.
The temperature of an object which is emitting light. If the absolute colour temperature is high, the colours tend to take on a 
bluish tinge. If the absolute colour temperature is lower, the colours tend to take on a reddish tinge.
Ad hoc mode
A method of wireless LAN connection that communicates with wireless LAN clients without using an access point.
Aspect ratio
The ratio between an images length and its height. HDTV images have an aspect ratio of 16:9 and appear elongated. The 
aspect ratio for standard images is 4:3.
Authentication server
This is a server that centrally manages user authentication. By using an authentication server, management of user information 
and user authentication tasks can be centralised. In addition, many authentication servers use high-level authentication 
methods and so they also tend to be highly secure.
CCX
Abbreviation for Cisco Compatible Extensions. This is a security technology for wireless LANs developed by Cisco Systems, 
Inc. It uses RADIUS server
g for authentication. Several authentication methods are available for CCX, and this projector uses 
LEAP
g authentication.
Component video
Video signals which have the video brightness signals and colour signals separated, in order to provide better image quality. 
In high-definition TV (HDTV), it refers to images which consist of three independent signals: Y (luminance signal), and Pb 
and Pr (colour difference signals).
Composite video
Video signals which have the video brightness signals and colour signals mixed together. The type of signals commonly used 
by household video equipment (NTSC, PAL and SECAM formats). 
The carrier signal Y (luminance signal) and chroma (colour) signal which are contained in the colour bar are overlapped to 
form a single signal.
Contrast
The relative brightness of the light and dark areas of an image can be increased or decreased in order to make text and 
graphics stand out more clearly, or to make them appear softer. Adjusting this particular property of an image is called 
contrast adjustment.
Cool-down
This is the process by which the projectors lamp is cooled down after it has become hot through use. Cool-down is carried out 
automatically when the [Power] button is pressed to turn off the power. Do not disconnect the power cable while cool-down is 
in progress, otherwise the cool-down process will not work properly. If the cool-down period is not allowed to finish normally, 
the projectors lamp and internal components will remain at high temperatures, and this may shorten the operating life of the 
lamp or cause problems with the operation of the projector.
DHCP
Abbreviation of Dynamic Host Configuration Protocol. This protocol automatically assigns an IP address to a computer 
connected to a network. 
Dolby Digital
A sound format developed by Dolby Laboratories. Normal stereo is a 2-channel format which uses two speakers. Dolby 
Digital is a 6-channel (5.1-channel) system which adds to this a centre speaker two rear speakers and a sub-woofer.
DPOF
Abbreviation of Digital Print Order Format, which is a format used to record infomation concerning the printing of 
photographs taken with a digital camera (which images to print, how many copies, etc.) to recordable media, such as a 
memory card.
