Changing the Lamp WARNING: Before you begin any of the procedures in this section, follow the Safety Instructions as described on page 7.

WARNING: Use an original lamp to ensure safe and optimal working condition of your projector.

WARNING: 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.

WARNING: 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.

WARNING: If the lamp shatters, remove all broken pieces from the projector and dispose or recycle according to state, local, or federal law. For more information see www.dell.com/hg.

1 Turn off the projector and disconnect the power cord. 2 Let the projector cool for at least 30 minutes. 3 Loosen the screws that secure the lamp

cover, and remove the cover. 4 Loosen the screw that secures the lamp. 5 Pull the lamp up by its metal handle.

NOTE: Dell may require lamps replaced under warranty to be returned to Dell. Otherwise, contact your local waste disposal agency for the address of the nearest deposit site.

6 Replace with the new lamp. 7 Tighten the screw that secures the lamp. 8 Replace the lamp cover and tighten the

two screws. 9 Reset the lamp usage time by selecting

"Confirm" for Lamp Hour Reset in the Power Settings (see "Power Settings" on page 41). When a new lamp module has been changed, the projector will automatically detect and reset the lamp hours.

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 lamps shortened operating life span or possible lamp failure.

7 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 kind 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.

Glossary 58

2 ANSI 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.

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).

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.

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

Glossary 59

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, closely related to PAL but with a different method of sending color information.

SSID Service Set Identifiers A name used to identify the particular wireless LAN to which a user wants to connect.

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.

XGA Extended Video Graphics Array 1024 x 768 pixels count.

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.
