Safety P ecaution
WARNING
Service should not be attempted by anyone unfamiliar with the necessary precautions on this
monitor.
The followings are the necessary precautions to be observed before servicing.
1. When managing this monitor, cover with shield plate to avoid to scrach on LCD surface.
. When replacing a chassis in the cabinet, always be certain that all the protective devices are
put back in place, such as nonmetallic control knobs, insulating covers, shields, isolation
resistor capacitor network etc.
3. Before returning the monitor to the customer, always perform an AC leakage current check
on the exposed metallic parts of the cabinet, such as signal connectors, terminals, screw
heads, metal overlays, control shafts etc, to be sure the monitor is safe to operate without
danger of electrical shock.

by pressing the /VOLUME or /MUTE buttons.
User:
You can also define the RGB values yourself. Press the
/VOLUME or /MUTE buttons to select Red, Green
or Blue. Then press the SELECT/AUTO button.
H Position: Controls the picture’s horizontal position.
V Position: Controls the picture’s vertical position.
Phase: Adjusts the internal clock’s time lag in order to
optimize the screen image.
Clock: Sets up the internal clock. Larger values make
the displayed image appear wider; smaller values make
it appear compressed.
Recall: Restores the image settings to their factory
values.
OSD Time: Determines the time (in seconds) to wait
before the OSD menu is automatically closed when no
changes are made.
OSD Position: Controls the horizontal and vertical
position of the OSD menu.
Auto Color: Automatic color settings.
Language: OSD menu language selection: English,
German, French, Italian, Spanish, Portuguese, Danish,
Swedish, Finnish, Dutch, Korean, Japanese, Chinese.
Automatically selects the optimal values for the image
settings (image position, phase, etc.).
Controls the selection of the input signal. The monitor
allows you to make the following connections: analog
graphics card via the 15-pin mini D-Sub interface (see
fig. 2a), digital graphics card via the DVI-D interface
(see fig. 2b).
