Changing the Lamp  
CAUTION: Before you begin any of the procedures in this section,  
follow the Safety Instructions as described on page 7.  
Replace the lamp when the message "Lamp is approaching the end of its  
useful life in the operation. Replacement suggested!  
www.dell.com/lamps" appears on the screen. If this problem persists after  
replacing the lamp, contact Dell. For more information, see "Contacting  
Dell" on page 51.  
CAUTION: Use an original lamp to ensure safe and optimal  
working condition of your projector.  
CAUTION: The lamp becomes very hot when in use. Do not  
attempt to replace the lamp until the projector has been allowed to  
cool down for at least 30 minutes.  
CAUTION: Do not touch the bulb or the lamp glass at any time.  
Projector lamps are very fragile and may shatter if touched. The  
shattered glass pieces are sharp and can cause injury.  
CAUTION: If the lamp shatters, remove all broken pieces from the  
projector and dispose or recycle according to state, local, or federal

Lamp life  
NOTE: The lamp life rating for any projector is a measure of  
brightness degradation only, and is not a specification for the time it  
takes a lamp to fail and cease light output. Lamp life is defined as the  
time it takes for more than 50 percent of a lamp sample population to  
have brightness decrease by approximately 50 percent of the rated  
lumens for the specified lamp. The lamp life rating is not guaranteed  
in any way. The actual operating life span of a projector lamp will vary  
according to operating conditions and usage patterns. Usage of a  
projector in stressful conditions which may include dusty  
environments, under high temperatures, many hours per day, and  
abrupt powering-off will most likely result in a lamp’s shortened  
operating life span or possible lamp failure.

Appendix: Glossary

ANSI Lumens — A standard for measuring the brightness. It is calculated by  
dividing a square meter image into nine equal rectangles, measuring the  
lux (or brightness) reading at the center of each rectangle, and averaging  
these nine points.  
Aspect Ratio — The most popular aspect ratio is 4:3 (4 by 3). Early  
television and computer video formats are in a 4:3 aspect ratio, which  
means that the width of the image is 4/3 times the height.  
Brightness — The amount of light emitted from a display or projection  
display or projection device. The brightness of projector is measured by  
ANSI lumens.  
Color Temperature — The color appearance of white light. Low color  
temperature implies warmer (more yellow/red) light while high color  
temperature implies a colder (more blue) light. The standard unit for color  
temperature is Kelvin (K).  
Component Video — A method of delivering quality video in a format that  
consists of the luminance signal and two separate chrominance signals  
and are defined as Y'Pb'Pr' for analog component and Y'Cb'Cr' for digital  
component. Component video is available on DVD players.  
Composite Video — A video signal that combines the luma (brightness),  
chroma (color), burst (color reference), and sync (horizontal and vertical  
synchronizing signals) into a signal waveform carried on a single wire pair.  
There are three kinds of formats, namely, NTSC, PAL, and SECAM.  
Compressed Resolution — If the input images are of higher resolution than  
the native resolution of the projector, the resulting image will be scaled to  
fit the native resolution of the projector. The nature of compression in a  
digital device means that some image content is lost.  
Contrast Ratio — Range of light and dark values in a picture, or the ratio  
between their maximum and minimum values. There are two methods  
used by the projection industry to measure the ratio:  
1
Full On/Off — measures the ratio of the light output of an all white image  
(full on) and the light output of an all black (full off) image.  
2
ANSI — measures a pattern of 16 alternating black and white rectangles.  
The average light output from the white rectangles is divided by the  
52  
Glossary  
   
average light output of the black rectangles to determine the ANSI contrast  
ratio.  
Full On/Off contrast is always a larger number than ANSI contrast for the  
same projector.  
dB — decibel — A unit used to express relative difference in power or  
intensity, usually between two acoustic or electric signals, equal to ten  
times the common logarithm of the ratio of the two levels.  
Diagonal Screen — A method of measuring the size of a screen or a  
projected image. It measures from one corner to the opposite corner. A 9  
FT high, 12 FT wide, screen has a diagonal of 15 FT. This document  
assumes that the diagonal dimensions are for the traditional 4:3 ratio of a  
computer image as per the example above.  
DHCP — Dynamic Host Configuration Protocol — A network protocol that  
enables a server to automatically assign a TCP/IP address to a device.  
®
DLP — Digital Light Processing™ — Reflective display technology  
developed by Texas Instruments, using small manipulated mirrors. Light  
passing through a color filter is sent to the DLP mirrors which arrange the  
RGB colors into a picture projected onto screen, also known as DMD.  
DMD — Digital Micro-Mirror Device — Each DMD consists of thousands of  
tilting, microscopic aluminum alloy mirrors mounted on a hidden yoke.  
Focal Length — The distance from the surface of a lens to its focal point.  
Frequency — It is the rate of repetition in cycles per seconds of electrical  
signals. Measured in Hz (Hertz).  
HDCP — High-Bandwidth Digital-Content Protection — A specification  
developed by Intel™ Corporation to protect digital entertainment across  
digital interface, such as DVI, HDMI.  
HDMI — High-Definition Multimedia Interface — HDMI carries both  
uncompressed high definition video along with digital audio and device  
control data in a single connector.  
Hz (Hertz) — Unit of frequency.  
Keystone Correction — Device that will correct an image of the distortion  
(usually a wide-top narrow-bottom effect) of a projected image caused by  
improper projector to screen angle.  
Maximum Distance — The distance from a screen the projector can be to  
cast an image that is usable (bright enough) in a fully darkened room.  
Maximum Image Size — The largest image a projector can throw in a  
darkened room. This is usually limited by focal range of the optics.  
Glossary  
53  
Minimum Distance — The closest position that a projector can focus an  
image onto a screen.  
NTSC — National Television Standards Committee. North American  
standard for video and broadcasting, with a video format of 525 lines at 30  
frames per second.  
PAL — Phase Alternating Line. A European broadcast standard for video  
and broadcasting, with a video format of 625 lines at 25 frames per second.  
Reverse Image — Feature that allows you to flip the image horizontally.  
When used in a normal forward projection environment text, graphics, etc.  
are backwards. Reverse image is used for rear projection.  
RGB — Red, Green, Blue — typically used to describe a monitor that  
requires separate signals for each of the three colors.  
SECAM — A French and international broadcast standard for video and  
broadcasting, closely related to PAL but with a different method of sending  
color information.  
SVGA — Super Video Graphics Array — 800 x 600 pixels count.  
SXGA — Super Extended Graphics Array, — 1280 x 1024 pixels count.  
UXGA — Ultra Extended Graphics Array — 1600 x 1200 pixels count.  
VGA — Video Graphics Array — 640 x 480 pixels count.  
WEP — Wired Equivalent Privacy — This is a method for encrypting  
communication data. The encryption key is created and notified only to the  
communicating user, so the communication data cannot be decrypted by  
a third party.  
XGA — Extended Video Graphics Array — 1024 x 768 pixels count.  
WXGA — Wide Extended Graphics Array — 1280 x 800 pixels count.
