8. Please pay special attention to power supply overloads, as electrical shock or fire may occur.

9. Do not place anything on the power cord. Do not hang the power cord over an area where people or objects may pass.

10. In case the monitor is not be used for an extended period, turn off power to avoid the possibility of short circuits
caused by lightning.

11. In order to avoid electrical shock or fire risks, do not insert any object through any openings in the monitor’s
enclosure. Do not allow any liquid to come in contact with the monitor.

12. In case of any abnormal noise or odor caused by incorrect operation, turn off power immediately and contact a
professional technician. Do not attempt to repair this monitor by yourself, as electrical shock may occur when
opening the back cover or accessing internal components.

13. If any of the following conditions occurs, turn off power and contact a repair service provider:

1) the power cord is damaged or worn;

2) liquid has gotten into the monitor, or the monitor has experienced immersion or wetting;

3) the monitor has fallen;

4) the monitor’s performance shows obvious changes;

5) the monitor fails to work normally when correct procedures are followed. In that case, please make any

adjustments in accordance with instructions supplied with the monitor; do not attempt any changes to
established procedures, as further damage may occur, making successful repair of the monitor more difficult.

the LCD display. (Look for instructions on “changing the refresh rate” in the graphics card's
user guide.)

• If necessary, make small adjustments using H. POSITION and V. POSITION until the

screen image is completely visible. (The black border around the edge of the screen should
barely touch the illuminated “active area” of the LCD display.)

Main Menu Controls

Adjust the menu items shown below by using the up S and down T buttons.

Control Explanation

Auto Image Adjust sizes and centers the screen image automatically.

Contrast adjusts the difference between the image background (black level)

and the foreground (white level).

Brightness adjusts background black level of the screen image.

Input Select toggles between inputs if you have more than one computer

connected to the VG730m.

Audio Adjust
Vol ume increases the volume, decreases the volume, and mutes the audio.
Mute temporarily silences audio output.

Color Adjust provides several color adjustment modes, including preset color

temperatures and a User Color mode which allows independent adjustment of
red (R), green (G), and blue (B). The factory setting for this product is 6500K
(6500 Kelvin).

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.

5400K-Adds green to the screen image for a darker color.

1. Function test

1.1 products

17” LCD Monitor

2. Firmware and EDID upgrade/update Methods

Firmware Update Procedure

1. The monitor’s firmware update for VG730 have two method.

1.1. Download the MCU IC by the fire machine. This procedure is finished in SMT .

1.2. ISP Method. When the monitor’s BIOS isn’t exist or firmware isn’t final program, this method Is

worked by ISP Cord with monitor

2.1 Equipment Needed

2. VG730 monitor upgrade firmware by ISP Cord.

- USB cable for print port *1

- VGA cable*1

- LPT cable (25pin)*1

- AC power cable*1

- ISP fire cord ( the fixture is made in TE ) for firmware upgrade*1

- Power adapter for firmware upgrade (this adapter is made in TE)*1

- A computer with WindowsXP

- VG730 monitor ( no firmware)

- a additional monitor for system display

- ISP & ISP3.0 program

NOTE:

The fixture for firmware upgrade provide two different method to fire. Please check you monitor’s Main board,

refer to MCU-RSIC type and choose the method. Below form appear the relation between the method and the

MCU-RSIC type
