2. Precaution And Notices

2.1 Assembly Precaution

(1) Please do not press or scratch LCD panel surface with anything hard. And do not soil LCD panel surface by

touching with bare hands (Polarize film, surface of LCD panel is easy to be flawed)

In the LCD panel, the gap between two glass plates is kept perfectly even to maintain display characteristic

and reliability. If this panel is subject to hard pressing, the following occurs:

(a) Uniform color

(b) Orientation of liquid crystal becomes disorder

(2) Please wipe out LCD panel surface with absorbent cotton or soft cloth in case of it being soiled.

(3) Please wipe out drops of adhesive like saliva and water in LCD panel surface immediately.

They might damage to cause panel surface variation and color change.

(4) Do not apply any strong mechanical shock to the LCD panel.

2.2 Operating Precaution

(1) Please be sure to unplug the power cord before remove the back-cover. (Be sure the power is turn-off)

(2) Please do not change variable resistance settings in MAIN-BOARD; they are adjusted to the most suitable

value. If they are changed, it might happen LUMINANCE does not satisfy the white balance spec.

(3) Please consider that LCD backlight takes longer time to become stable of radiation characteristic in low

temperature than in room temperature.

(4) Please pay attention to displaying the same pattern for very long-time. Image might stick on LCD.

2.3 Storage Precaution

(1) When you store LCD for a long time, it is recommended to keep the temperature between 0°C -40°C without

the exposure of sunlight and to keep the humidity less than 85% RH.

(2) Please do not leave the LCD in the environment of high humidity and high temperature such as 60°C,

85%RH.

(3) Please do not leave the LCD in the environment of low temperature; below -25°C.

2.4 High Voltage Warning

The high voltage was only generated by INVERTER module on Power Board, if carelessly contacted the

transformer on this module, can cause a serious shock. (The lamp voltage after stable around 600V, with lamp

current around 8mA, and the lamp starting voltage was around 1500V, at Ta=25°C)

3. D-SUB Pin Descriptions

3.1 D-SUB Connector

This procedure gives you instructions for installing and using the LCD TV display.

1. Position the display on the desired operation and plug the power cord into a convenient AC outlet. Three-wire power cord must be shielded and is provided as a safety precaution as it connects the chassis and cabinet to the electrical conduct ground. If the AC outlet in your location does not have provisions for the grounded type plug, the installer should attach the proper adapter to ensure a safe ground potential.

2. Connect the 15-pin color display s hielded s ignal cab le to yo ur signal syste m devic e and loc k both s crews on

the connector to ensure firm grounding. The connector information is as follow:

4. Apply power to the display by turning the power switch to the "ON" position and allow about ten secon ds for

Panel warm-up. The Power-On indicator lights "GREEN" when the display is on.

5. With proper signals feed to the display, a pattern or data should appear on the screen, adjust the brightness and contrast to the most pleasing display, or press auto-adjust to get the best picture-quality.

6. This TV (with PC function) has power saving function following the VESA DPMS. Be sure to connect the

signal cable to the PC.

7. If your TV requires service, it must be returned with the power cord.
