1. Precautions and Safety Notices

1.Please carefully read this manual before operating the device and keep it available for future reference.

2.	To avoid the danger of the monitor falling and thereby possibly causing injury and/or serious damage to the monitor
	itself, do not place it on unstable cars or desks. Be careful to avoid placing any stress on the LCD screen during
	handling.

3.Do not place this monitor in areas that are wet or where water or other liquids may come in contact with it, such as bathrooms, kitchens, wet floors, near washing machines or by swimming pools.

4.Remove the power plug from the electrical socket before cleaning. No water-containing cleaning agent should be used to clean the screen, but only cleaning agents formulated specifically for cleaning LCD screens. Do not put any liquid cleaning agent directly on the screen, but put it on a soft cloth first and then gently apply the cloth to the screen.

5.In order to guarantee reliable operation and adequate heat dissipation, do not cover or block vent holes on the monitor. Do not put the monitor close to heat sources. Do not place the monitor on furniture such as a bookshelf, unless sufficient ventilation is available.

6.A 3-pin grounding plug is provided for this monitor. In order to guarantee normal operation and safety of this unit, this plug should be used with a matching grounded power socket.

7.Please follow all warnings and instructions that accompany the monitor.

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.

14.In case parts need to be replaced, you must use identical parts or those supplied by our certified

manufacturers. Any other parts used without our authorization may result in electrical shock or fire risk.

5.To save the adjustments and exit the menu, press button [1] twice.

The following tips may help you optimize your display:

•Adjust the computer's graphics card so that it outputs a 1280 x 1024 @ 60Hz video signal to 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

Volume 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.

Control Explanation

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.

Information displays the timing mode (video signal input) coming from the graphics card in the computer, the LCD model number, the serial number, and the ViewSonic® website URL. See your graphics card’s user guide for instructions on changing the resolution and refresh rate (vertical frequency). NOTE: VESA 1280 x 1024 @ 60Hz (recommended) means that the resolution is 1280 x 1024 and the refresh rate is 60 Hertz.

Manual Image Adjust

H. Size (Horizontal Size) adjusts the width of the screen image.

H./V. Position (Horizontal/Vertical Position) moves the screen image left or right and up or down.

5. Adjusting Procedure

1.Function test

1.1products 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

2.1Equipment 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
