Precautions
To preserve optimal performance of this equipment
Magnetic Cautions
·Do not place the unit near any objects which generate magnetism. Magnetism will
cause picture bounce, oscillations or picture discoloration.
·The picture may become fuzzy or the colors may not reproduce correctly due to the
Earth’s magnetism. This depends on the direction that the unit is installed. This is not
an equipment failure. In such a case, simply turn off and on or push the DEGAUSS
button to resolve the issue.
For details about the DEGAUSS button, see “DEGAUSS button” on page 8.
Picture Tube Cautions
·For dirt or stains, wipe the surface of the panel gently with a clean soft cloth that has
been lightly dampened with a well-diluted soft detergent and wrung out thoroughly, then
dry it off with a dry cloth. Avoid excessive moisture. Do not spray detergent or other
cleaners directly on the screen.
·The surface of the CRT is easily scratched: therefore, do not rub or touch the surface
of the CRT.
·To prevent damage to the surface of the screen do not use strong solvents such as aerosol
cleaners, alkaline detergents, alcohols, benzene, or thinners.
Cleaning Cautions
·Turn off and unplug the unit before cleaning.
·When dusting or polishing the cabinet, use a clean soft cloth dampened with a water-
diluted mild detergent (water: soap = 6:1) and wrung out thoroughly, then wipe dry with
a soft clean cloth. Do not spray detergent or other cleaners directly on unit.
·Never use strong solvents such as thinner, benzene, and other petroleum-based
cleaners.

Features
Image
Resolution
Fine Dot Pitch Shadow Mask provides a center resolution of more than 800 Lines.
Comb Filter
Comb filter removes cross color interference (rainbow phenomenon at letters) and color
noise (color spread) to display crisp and clear images.
Beam current feedback Circuit
The beam current feedback Circuit maintains a constant color temperature over long
periods of time.
2 Color Systems
This unit automatically adjusts to respond appropriately to NTSC and PAL Color Systems.
Input
Analog RGB/Component Input
You can input analog RGB, component signals(Y, Pb, Pr). Pushing the COMPONENT
button at the front panel, then you can select RGB/COMPONENT signal on the OSD
menu.
Y/C Input
You can input brightness signal(Y) and color signal(C) separately to reduce color
spreads or blinking so that you can get clearer images.
External Synchronization Signal Input-terminal
You can input synchronization signals from external synchronization signal generator.
The external synchronization signal input can be selected by pushing the EXIT button
when inputting RGB/COMPONENT.
Auto Termination ( )
The Input-Terminal on the rear panel is terminated automatically if it is not connected to an
output-terminal. When it is connected to an output-terminal via a cable, the internal auto
termination is cancelled automatically and the signals inputted at the input-terminal are
looped through to the output-terminal.
SDI Input
You can input SDI signals from video equipment and display these signals by selecting
CVBS/SDI button on the front panel.
