Procedure
1Turn off the projector power, wait 
for the cool-down
 period to end, 
and then disconnect the power 
cable.
The cool-down period lasts for about 20 
seconds. The actual time will vary 
depending on the external air  
temperature.
2Put your finger into the recess, and 
pull straight out to remove the air 
filter.
3Install the new air filter.
Slide the cover in from the outside, and 
then push it in until it clicks into place.
Tip :
Dispose of used air filters properly in accordance 
with your local regulations.

Glossary
Following is an explanation of some of the terms used in this guide which may 
be unfamiliar or which were not explained in the text of this guide itself. 
Further information can be obtained by referring to other commercially-
available publications.
Aspect ratioThe 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.
Colour 
temperatureThe temperature of an object which is emitting light. If the colour 
temperature is high, the colours tend to take on a bluish tinge. If the 
colour temperature is lower, the colours tend to take on a reddish tinge.
Component 
videoVideo 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 
videoVideo 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.
ContrastThe 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-downThe cooling process for the projectors lamp unit continues even after 
the [Power] button on the projectors control panel or the remote control 
has been pressed to turn off the lamp. After the lamp turns off, the 
cooling fan continues operating, but all button operations are disabled. 
The length of time that this is happening is called the cool-down 
period. The cool-down period lasts for about 20 seconds. The actual 
time will vary depending on the external air temperature.
Dolby DigitalA 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.
HDTVAn abbreviation for High-Definition Television. It refers to high-
definition systems which satisfy the following conditions.
 Vertical resolution of 750p or 1125i or greater (p = progressive 
scanning, i = interlaced scanning)
 Screen aspect ratio
 of 16:9
 Dolby Digital
 audio reception and playback (or output) 
						

							82 Interlaced 
scanningA method of image scanning whereby the image data is divided into 
fine horizontal lines which are displayed in sequence starting from left 
to right and then from the top to the bottom of the screen. The even-
numbered lines and odd-numbered lines are displayed alternately.
Progressive 
scanningA method of image scanning whereby the image data from a single 
image is scanned sequentially from top to bottom to create a single 
image.
Refresh rateThe light-emitting element of a display maintains the same luminosity 
and colour for an extremely short time. Because of this, the image must 
be scanned many times per second in order to refresh the light-emitting 
element. The number of refresh operations per second is called the 
refresh rate, and is expressed in hertz (Hz).
Resize 
displayThis function is use to project computer images that have a resolution 
or more than or less than the projectors panel resolution to be projected 
so that they fill the whole of the projection area.
Security 
lockA device consisting of a projector case with a hole in it that a 
commercially-available theft-prevention cable can be passed through in 
order to secure the device to a table or pillar. This projector is 
compatible with the Microsaver Security System manufactured by 
Kensington.
SDTVAn abbreviation for Standard Definition Television. It refers to standard 
television systems which do not satisfy the conditions for High-
Definition Television.
sRGBAn international standard for colour intervals that was formulated so 
that colours which are reproduced by video equipment can be handled 
easily by computer operating systems (OS) and the Internet.
SVGAA type of video signal with a resolution of 800 (horizontal) x 600 
(vertical) dots which is used by IBM PC/AT-compatible computers.
S-VideoA video signal which has the luminance component and colour 
component separated in order to provide better image quality.
It refers to images which consist of two independent signals: Y 
(luminance signal), and C (colour signal).
Sync.
(Synchroni-
sation)The signals output from computers have a specific frequency. If the 
projector frequency does not match this frequency, the resulting images 
will not be of a good quality. The process of matching the phases of 
these signals (the relative position of the crests and troughs in the 
signal) is called synchronisation. If the signals are not synchronized, 
problems such as flickering, blurriness and horizontal interference can 
occur.
Tr a c k i n gThe signals output from computers have a specific frequency. If the 
projector frequency does not match this frequency, the resulting images 
will not be of a good quality. The process of matching the frequency of 
these signals (the number of crests in the signal) is called tracking. If 
tracking is not carried out correctly, wide vertical stripes will appear in 
the projected images.

							83 VGAA type of video signal with a resolution of 640 (horizontal) x 480 
(vertical) dots which is used by IBM PC/AT-compatible computers.
XGAA type of video signal with a resolution of 1024 (horizontal) x 768 
(vertical) dots which is used by IBM PC/AT-compatible computers.
YCbCrThe carrier signal which is contained in the colour bar signal used in 
modern TV transmissions. The name comes from the Y (luminance) 
signal and the CbCr (chroma (colour)) signals.
YPbPrThe carrier signal which is contained in the colour bar signal used in 
high-definition TV (HDTV) transmissions. The name comes from the 
Y (luminance) signal and the PbPr (colour difference) signals.

List of ESC/VP21 Commands
Command List
When a power ON command is sent to the projector, the power for the projector 
turns on. When the projector is in a command ready state, it returns the 3Ah 
(:) code. Furthermore, when command processing is complete, the projector 
also returns a : code.
The : code status can be used to determine whether the projector is ready or 
busy. If command processing terminates with an error, an error message is 
output and then the : code is sent.
