Temporarily erases the image and sound. The sound and image can be muted
by pressing the [A/V Mute] button on the projector. Press the [A/V Mute]
button once again or adjust the volume or display the menu to cancel the mute
mode.
By strengthening or weakening the tone of the colors, it is possible to project
characters and pictures more clearly and attain a softer tint. This is known as
contrast adjustment.
Video equipment transmits signals through three cables as Red-Bright (R-Y),
Yellow-Bright (Y) and Blue-Bright (B-Y). This enables the composite signals
(the red, green and blue signals and their brightness signals are transmitted
along one cable) to be projected more clearly.
The temperature of the subject that emits light. A blue hue is attained when
the color temperature is high, and a red hue is attained when the color temper-
ature is low.
A lamp cooling procedure continues to operate even after the power supply
has been switched off and the lamp extinguished. The cooling fan will begin
to operate when the lamp is extinguished, and button operations will no
longer be possible. This period is known as the cooling down period. The
amount of time required for the cooling down procedure will differ in accor-
dance with the surrounding temperature.
The output port for digital tuners that support the new digital broadcasts
within Japan.
The software necessary to operate the computer.
IBM PC/AT compatible (DOS/V equipment) signals with 800 horizontal pix-
els and 600 vertical pixels.
IBM PC/AT compatible (DOS/V equipment) signals with 1,280 horizontal
pixels and 1,024 vertical pixels.
Outputs computer signals at a pre-determined frequency. The image will not
be projected clearly unless this frequency is aligned with the frequency of the
projector. Aligning the signal phasing is known as synchronization. Projected
images will be subject to disturbance, blurring and horizontal noise if not syn-
chronized.
Outputs computer signals at a pre-determined frequency. The image will not
be projected clearly unless this frequency is aligned with the frequency of the
projector. Aligning the signal frequency is known as tracking. Projected
images will be subject to disturbance, blurring and horizontal noise if not syn-
chronized.
An abbreviation for Universal Serial Bus. This is an interface for connecting
comparitively low frequency equipment to the computer.
IBM PC/AT compatible (DOS/V equipment) signals with 1,600 horizontal
pixels and 1,200 vertical pixels.
IBM PC/AT compatible (DOS/V equipment) signals with 640 horizontal pix-
els and 480 vertical pixels.
