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.

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 1: Measurement method

The LCD module should be stabilized at given temperature for 30 minutes to avoid abrupt temperature

change during measuring (at surface 35 ). In order to stabilize the luminance, the measurement should be

executed after lighting Backlight for 30 minutes in a stable, windless and dark room.

Note 2: Definition of viewing angle measured by ELDIM (EZContrast 88)

Viewing angle is the measurement of contrast ratio 10, at the screen center, over a 180° horizontal and

180° vertical range (off-normal viewing angles). The 180° viewing angle range is broken down as follows;

90° (θ) horizontal left and right and 90° (Φ) vertical, high (up) and low (down). The measurement direction is

typically perpendicular to the display surface with the screen rotated about its center to developthe desired

measurement viewing angle.

Note 3: Contrast ratio is measured by TOPCON SR-3

Note 4: Definition of Response time measured by Westar TRD-100A

The output signals of photo detector are measured when the input signals are changed from “Full

Black” to “Full White” (rising time, TrR), and from “Full White” to “Full Black” (falling time, TrF),

respectively. The response time is interval between the 10% and 90% (1 frame at 60 Hz) of

amplitudes.

TrR + TrF = 5 msec (typ.).

Note 5: Color chromaticity and coordinates (CIE) is measured by TOPCON SR-3
