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.

Color Control:

Three different color temperatures are available:

User, Bluish and Reddish. Select the desired setting

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).
