FCC Statement Warning

This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection

against harmful interference in a residential installation. This equipment generates, uses, and can

radiate radio frequency energy, and if not installed and used in accordance with the instruction, may

cause harmful interference to radio communications. However, there is no guarantee that

interference will not occur in a particular installation. If this equipment does cause harmful

interference to radio or television reception, which can be determined by turning the equipment off

and on, the user is encouraged to try to correct the interference by one or more of the following

measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

• Consult the dealer or an experienced radio/TV technician for help.

Any changes or modifications not expressly approved by the manufacturers may void the user's

authority to operate this equipment.

NOTE

A shielded-type signal cord is required in order to meet the FCC emission limits and also to prevent

interference to the radio and television reception. It is essential that only the supplied signal cord be

used.

Chapter 1 Installation

Unpacking

Before unpacking the LCD Monitor, prepare a suitable workspace for your Monitor and computer.

You need a stable and clean surface near a wall power outlet. Make sure that LCD Monitor has

enough space around it for sufficient airflow. Though the LCD Monitor uses very little power,

some ventilation is needed to ensure that the Monitor does not become too hot.

After you unpack the LCD Monitor, make sure that the following items were included in the box:

* LCD Monitor * AC Adapter

* 1.5M Monitor-to-PC signal Cable * 1.8M Power Cord

* User's Manual * Base

If you find that any of these items is missing or appears damaged, contact your dealer immediately.

Connecting the LCD Monitor and Base

When you open the box to take the base

and put on the desk first. Then connect

the LCD Monitor and base please.(See

fig.1-1 )

Figure 1-1

Viewing Angle Adjustment

The LCD Monitor is designed to allow

users to have a comfortable viewing

angle. The viewing angle can be adjusted

from -5°to +35°.(See fig. 1-2)

Figure 1-2

Warning

Do not force the LCD Monitor over its maximum viewing angle settings as stated above. Attempting

this will result in damaging the Monitor and Monitor stand.

Troubleshooting

This LCD Monitor has pre-adjusted using factory standard VGA timings. Due to the output timing

differences among various VGA cards in the market, users may initially experience an unstable or

unclear display whenever a new display mode or new VGA card is selected.

Attention

This LCD Monitor Supports Multiple VGA Modes.

Refer to the Standard Timing Table for a listing of modes supported by this LCD Monitor.

PROBLEM Picture is unclear and unstable

The picture is unclear and unstable, please perform the following steps :

1. Enter PC to “Shut Down Windows” status while you’r e in MS-Windows environment.

2. Check the screen to see if there’s any black vertical stripes appear. If there are, take advantage of

the “Clock” function in OSD menu and adjust (by increment or decrement numbers) until those

bars disappear.

3. Move to “Phase” function in OSD menu again and adjust the monitor screen to its most clear

display.

4. Click “No” on “Shut Down Windows” and back to the normal PC operating environment.

PROBLEM There is no picture on LCD Monitor

If there’s no picture on the LCD Monitor, please perform the following steps:

1. Make sure the power indicator on the LCD Monitor is ON, all connections are secured, and the

system is running on the correct timing. Refer to Chapter 3 for information on timing.

2. Turn off the LCD Monitor and then turn it back on again. If there is still no picture, press the

Adjustment Control button several times.

3. If step 2 doesn’t work, connect your PC system to another external CRT. If your PC system

Functions properly with a CRT Monitor but it does not function with the LCD Monitor, the

output timing of the VGA card may be out of the LCD’s synchronous range. Please change to

an alternative mode listed in the Standard Timing Table or replace the VGA card, and then repeat

steps 1 and 2.

PROBLEM There is no picture on LCD Monitor

If you have chosen an output timing that is outside of the LCD Monitor’s synchronous range

(Horizontal: 24 ~ 61 KHz and Vertical: 56 ~ 75 Hz), the OSD will display a “Out of Range”

message. Choose a mode that is supported by your LCD Monitor.

Also, if the signal cable is not connected to LCD monitor at all or properly, the monitor screen will

display a message “No Input Signal”.
