Digital Projection Highlite 4000dsx User Manual

Before removing the lamphousing, switch off the lamp and allow the cooling fans to
run for three minutes. When the projector is in standby mode (power indicator
glows amber) disconnect from the mains supply and wait at least 10 minutes for the
projector to cool down. If the lamp has exceeded 1600 hours and the message “LP”
is displayed on the 7 segment display, it will be necessary to reset the projectors
internal running time by pressing the Help key or Power Off key on the remote con-
trol for 10...

1. Unplug the projector before cleaning.
2. Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild 
detergent. Never use strong detergents or solvents such as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be careful not to scratch or 
mark the lens.

Aspect Ratio
This is the ratio of picture width to picture height (the standard television aspect
ratio is 4x3).
Black body
An ideal body or surface that completely absorbs all light falling upon it with no
reflection.
Brightness
The light intensity of the displayed image.
Colour Temperature
The Colour Temperature is the position along the black body curve of the
chromaticity diagram - but takes into account the preset values for colour balance in
the service set-up to take up the variations in the...

Hs + Vs
This stands for Horizontal and Vertical sync.
Hue
The graduation (red/green balance) of colour (applicable to NTSC).
Hz - Hertz
Hertz is a measurement of frequency, where one hertz is one cycle per second.
Interlacing
An interlaced image is displayed by alternatively updating two fields of horizontal
display lines to produce a constant image. Field 1 (the odd lines) is updated, then
field 2 (the even lines) is updated.
LED
A Light Emitting Diode is an electronic component that emits light.
Lumen...

Resolution
This is expressed as the number of horizontal pixels by the number of vertical lines,
e.g. 680 x 400 means 400 lines with 680 pixels per line.
RGB
The Red, Green and Blue inputs from an RGB source.
S-Video
A video signal which has separate Y and C signals.
Throw Distance
The required distance between the screen and the projector.
Y
This is the luminance input (brightness) from an S-Video or component video 
signal.
