Appendix: Regulatory Notices
FCC Notices (U.S. Only)
Most Dell computer systems are classified by the Federal Communications Commission 
(FCC) as Class B digital devices. To determine which classification applies to your computer 
system, examine all FCC registration labels located on the bottom, side, or back panel of 
your computer, on card-mounting brackets, and on the cards themselves. If any one of the 
labels carries a Class A rating, your entire system is considered to be a Class A digital device. 
If all labels carry an FCC Class B rating as distinguished by either an FCC ID number or the 
FCC logo, ( ), your system is considered to be a Class B digital device.
Once you have determined your system’s FCC classification, read the appropriate FCC 
notice. Note that FCC regulations provide that changes or modifications not expressly 
approved by Dell could void your authority to operate this equipment.

Glossary
ANSI LUMENS —A standard for measuring light output, used for comparing 
projectors.
A
SPECT 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.
B
ACKLIT (BACKLIGHT) —Refers to a remote control, or a projector control panel, that 
has buttons and controls that are illuminated. 
Bandwidth— The number of cycles per second (Hertz) expressing the difference 
between the lower and upper limiting frequencies of a frequency band; also, the 
width of a band of frequencies.
Brightness— The amount of light emitting from a display or projection display or 
projection device. The brightness of projector is measured by ANSI lumens.
Color Temperature— A method of measuring the whiteness of a light source. 
Metal halide lamps have a higher temperature compared to halogen or 
incandescent lights.
Component Video—A method of delivering quality video in a format that 
contains all the components of the original image. These components are referred 
to as luma and chroma and are defined as YPbPr for analog component and 
YCbCr for digital component. Component video is available on DVD players and 
projectors.
Composite Video — The combined picture signal, including vertical and 
horizontal blanking and synchronizing signals.
Compression— A function that deletes resolution lines from the image to fit in 
the display area.
Compressed SVGA— To project an 800x600 image to a VGA projector, the 
original 800x600 signal must be compressed down. The data displays all the 
information with only two thirds of the pixels (307,000 vs 480,000). The resulting 
image is SVGA page size but sacrifices some of the image quality. If you are using 
an SVGA computers, connecting VGA to a VGA projector. provide better results.
Compressed SXGA— Found on XGA projectors, compressed SXGA handling 
allows these projectors to handle up to 1280x1024 SXGA resolution. 
Compressed XGA— Found on SVGA projectors, compressed XGA handling 
allows these projectors to handle 1024x768 XGA resolution. 
						

							76Glossary
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:
1Full  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. 
2ANSI — measures a pattern of 16 alternating black and white rectangles. The 
average light output from the white rectangles is divided by the 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 9FT high, 12FT 
wide, screen has a diagonal of 15FT. This document assumes that the diagonal 
dimensions are for the traditional 4:3 ratio of a computer image as per the example 
above. 
DLP— Digital Light Processing—Reflective display technology developed by 
Texas Instruments, using small manipulated mirrors. Light passes 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.  
DVI— Digital Visual Interface— Defines the digital interface between digital 
devices such as projectors and personal computers. For devices that support DVI, a 
digital to digital connection can be made that eliminates the conversion to analog 
and thereby delivers an unblemished image. 
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. 
Hz — Frequency of an alternating signal. See 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.
Laser Pointer— A small pen or cigar sized pointer that contains a small battery 
powered laser, which can project a small, red (typically), high intensity beam of 
light that is immediately very visible on the screen. 
						

							Glossary77
Maximum Distance— The distance from a screen the projector can be to cast an 
image that is useable (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. 
Metal Halide Lamp— The type of lamp used in many medium and all high end 
portable projectors. These lamps typically have a half-life of 1000-2000 hours. 
That is they slowly lose intensity (brightness) as they are used, and at the half-life 
point, they are half as bright as when new. These lamps output a very hot 
temperature light, similar to mercury vapor lamps used in streetlights.. Their 
whites are extremely white (with slight bluish cast.) and make Halogen lamps 
whites look very yellowish by comparison.
Minimum Distance— The closest position that a projector can focus an image 
onto a screen.
NTSC— The United States broadcast standard for video and broadcasting.
PAL— A European and international broadcast standard for video and 
broadcasting. Higher resolution than NTSC.
Power Zoom— A zoom lens with the zoom in and out controlled by a motor, 
usually adjusted from the projectors control panel and also the remote control.
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.
S-Video—A video transmission standard that uses a 4-pin mini-DIN connector to 
send video information on two signal wires called luminance (brightness, Y) and 
chrominance (color, C). S-Video is also referred to as Y/C.
SECAM— A French and international broadcast standard for video and 
broadcasting. Higher resolution than NTSC.
SVGA— Super Video Graphics Array— 800 x 600 pixels count.
SXGA— Super Ultra 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.
XGA— Extra Video Graphics Array— 1024 x 768 pixels count. 
						

							78Glossary
Zoom Lens— Lens with a variable focal length that allows operator to move the 
view in or out making the image smaller or larger. 
Zoom Lens Ratio— Is the ratio between the smallest and largest image a lens can 
projector from a fixed distance. For example, a 1.4:1 zoom lens ratio means that a 
10 foot image without zoom would be a 14 foot image with full zoom.
