Safety Instruction
Read and follow these instructions when connecting and using your LCD monitor:
Operation:
1. Keep the monitor out of direct sunlight and away from stoves or any other heat
source.
2. Remove any object that could fall into ventilation holes or prevent proper cooling
of the monitor＇s electronics.
3. Do not block the ventilation holes on the cabinet.
4. When positioning the monitor, make sure the power plug and outlet are easily
accessible.
5. If turning off the monitor by detaching the power cable or DC power cord, wait
for seconds before attaching the power cable or DC power cord for normal
operation.
6. Do not subject the LCD monitor to severe vibration or high impact conditions
during operation.
7. Do not knock or drop the monitor during operation or transportation.
Maintenance:
8. To protect your display from possible damage, do not put excessive pressure on
the LCD panel. When moving your monitor, grasp the frame to lift; do not lift the
monitor by placing your hand or fingers on the LCD panel.
9. Unplug the monitor if you are not going to use it for an extensive period of time.
10. Unplug the monitor if you need to clean it with a slightly damp cloth. The screen
may be wiped with a dry cloth when the power is off. However, never use organic
solvent, such as, alcohol, or ammonia-based liquids to clean your monitor.
11. To avoid the risk of shock or permanent damage to the set, do not expose the
monitor to dust, rain, water, or excessive moisture environment.
12. If your monitor gets wet, wipe it with dry cloth as soon as possible.
13. If foreign substance or water gets in your monitor, please turn the power off
immediately and disconnect the power cord. Then, remove the foreign substance
or water, and send it to the maintenance center.
14. Do not store or use the LCD monitor in locations exposed to heat, direct sunlight
or extreme cold.
15. In order to maintain the best performance of your monitor and use it for a longer
lifetime, please use the monitor in a location that falls within the following
temperature and humidity ranges. Temperature: 5-35°C 41-95°F

Product Installation
1. Switch off the power on both your monitor and your computer. The Power Switch
is located in the right of the monitor.
2. Connect the power cord to the AC outlet, and connect the power to the monitor
through the AC/DC adapter.
3. VGA Signal-Plug one end of the 15-pin signal cable to the video signal connector
at the rear of the PC system and the other end to the monitor. Secure the
connectors with the screws on the cable connector at both ends.
4. (Optional) DVI Signal-Plug one end of the DVI signal cable to the video signal
connector at the rear of the PC system and the other end to the monitor. Secure
the connectors with the screws on the cable connector at both ends.
5. (Optional) HDMI Signal-Plug one end of the HDMI signal cable to the video
signal connector at the rear of the PC system and the other end to the monitor.
Secure the connectors with the screws on the cable connector at both ends.
6. (Optional) RS232 Connection- Plug one end of RS232 cable to com-port
connector on your PC system and the other end to the monitor. Secure the
connectors with the screws on the cable connector at both ends.

Panel Specification
Note (3) The lamp frequency may generate interference with horizontal synchronous frequency from the
display, and this may cause line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronousfrequency and its harmonics as far
as possible.
Note (4) PL= IL×VL
Note (5) The lifetime of lamp is defined as the time when it continues to operate under the conditions at Ta
= 25 ±2 oC and IL=6.5mARMS until one of the following events occurs:
(a)When the brightness becomes ≦50% of its original value.
(b)When the effective ignition length becomes ≦80% of its original value. (Effective ignition
length is defined as an area that the brightness is less than 70% compared to the center point.)
Note (6) The waveform of the voltage output of inverter must be area-symmetric and the design of the
inverter must have specifications for the modularized lamp. The performance of the Backlight,
such as lifetime or brightness, is greatly influenced by the characteristics of the DC-AC inverter for
the lamp. All the parameters of an inverter should be carefully designed to avoid generating too
much current leakage from high voltage output of the inverter. When designing or ordering the
inverter please make sure that a poor lighting caused by the mismatch of the Backlight and the
inverter (miss-lighting, flicker, etc.) never occurs. If the above situation is confirmed, the module
should be operated in the same manners when it is installed in your instrument.

Note (2) When the interface signal is invalid, be sure to pull down the power supply of LCD VDD to 0 V.
Note (3) The Backlight inverter power must be turned on after the power supply for the logic and the
interface signal is valid. The Backlight inverter power must be turned off before the power supply
for the logic and the interface signal is invalid.

Note (1) Definition of Viewing Angle (θx, θy):
Note (2) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR) = L255 / L0
L63: Luminance of gray level 255
L 0: Luminance of gray level 0
CR = CR (5)
CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (5).

Note (4) Measurement Setup:
The LCD module should be stabilized at given temperature for 20 minutes to avoid abrupt
temperature change during measuring. In order to stabilize the luminance, the measurement
should be executed after lighting Backlight for 20 minutes in a windless room.
Note (5) Definition of White Uniformity (δW):
Measure the luminance of gray level 255 at 5 points
δW = Minimum [L (1), L (2), L (3), L (4), L (5)] / Maximum [L (1), L (2), L (3), L (4), L (5)] * 100%
