1. Precautions and Safety Notices

1. Appropriate Operation

(1) Turn off the product before cleaning.

(2) Use only a dry soft cloth when cleaning the LCD panel surface.

(3) Use a soft cloth soaked with mild detergent to clean the display housing.

(4) Use only a high quality, safety approved AC/DC power cord.

(5) Disconnect the power plug from the AC outlet if the product will not be used for a long

period of time.

(6) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD

display off.

(7) Do not touch the LCD panel surface with sharp or hard objects.

(8) Do not place heavy objects on the LCD display, video cable, or power cord.

(9) Do not use abrasive cleaners, waxes or solvents for your cleaning.

(10) Do not operate the product under the following conditions:

y Extremely hot, cold or humid environment.

y Areas containing excessive dust and dirt.

y Near any appliance generating a strong magnetic field.

y In direct sunlight.

2. Caution

No modification of any circuit should be attempted. Service work should only be performed

after you are thoroughly familiar with all of the following safety checks and servicing

guidelines.

3. Safety Check

Care should be taken while servicing this LCD display. Because of the high voltage used in

the inverter circuit, the voltage is exposed in such areas as the associated transformer

circuits.

4. LCD Module Handling Precautions

4.1 Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.

(2) Be sure to turn off power supply when connecting or disconnecting input connector.

(3) Wipe off water drops immediately. Long contact with water may cause discoloration or

spots.

(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.

(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard

surface.

(6) Since CMOS LSI is used in this module, take care of static electricity and ensure human

earth when handling.

(7) Do not open or modify the Module Assembly.

(8) Do not press the reflector sheet at the back of the module in any direction.

(9) In the event that a Module must be put back into the packing container slot after it was

taken out of the container, do not press the center of the CCFL Reflector edge. Instead,

press at the far ends of the CFL Reflector edge softly. Otherwise the TFT Module may

be damaged.

(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate or

tilt the Interface Connector of the TFT Module.

(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for

example), do not twist or bend the TFT Module even momentarily. When designing the

enclosure, it should be taken into consideration that no bending/twisting forces may be

applied to the TFT Module from outside. Otherwise the TFT Module may be damaged.

(12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury.

Please follow local ordinances or regulations for disposal.

(13) The LCD module contains a small amount of materials having no flammability grade.

The LCD module should be supplied with power that complies with the requirements of

Limited Power Source (IEC60950 or UL1950), or an exemption should be applied for.

(14) The LCD module is designed so that the CCFL in it is supplied by a Limited Current

Circuit (IEC60950 or UL1950). Do not connect the CCFL to a Hazardous Voltage Circuit

Control Explanation

sRGB-This is quickly becoming the industry standard for color management,

with support being included in many of the latest applications. Enabling this setting allows the LCD display to more accurately display colors the way they were originally intended. Enabling the sRGB setting will cause the Contrast and Brightness adjustments to be disabled.

9300K-Adds blue to the screen image for cooler white (used in most office

settings with fluorescent lighting).

7500K - Adds blue to the screen image for cooler white (used in most office

settings with fluorescent lighting).

6500K-Adds red to the screen image for warmer white and richer red.

5000K-Adds green to the screen image for a darker color.

User Color Individual adjustments for red (R), green (G), and blue (B).

1. To select color (R, G or B) press button [2].

2. To adjust selected color, pressSandT. Important: If you select RECALL from the Main Menu when the product is

set to a Preset Timing Mode, colors return to the 6500K factory preset.
