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 separ ation 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.

Canadian DOC Notice

This Class B digital apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations.

Chapter 1 Installation

Unpacking

Before unpacking the LCD Monitor, prepare a suitable workspace for your Monitor and
computer. You need a stab l e and cl ean su rf ace near a wal l po wer ou tl et. Make su re t hat 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 follo wing items wer e 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 Monito r and base pl ease.(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.

Detaching LCD Monitor from Its Stand

1. Unscrew screws of the hinge bracket

2. Remove the stand from LCD monitor

(See fig. 1-3 )

Interface for Arm Applications

Before installing to mounting device, please
refer to Fig.1-3.
The rear of this LCD display has four
integrated 4 mm, 0.7 pitches threaded nuts,
as well as four 5 mm access ho les in the
plastic covering as illustrated in Figure 1-4.
These specificatio ns meet the VESA Flat

Panel Monitor Physical Mounting
Interface Standard (paragraphs 2.1 and

2.1.3, version 1, dated 13 November 1997).

Figure 1-3

Figure 1-4

Connecting the Display to your Comput er

1. Power off your computer.

2. Connect one end of the signal cable to the

LCD Monitor's VGA port. (See Fig. 1-5)

3. Connect the other end of the signal cable

to the VGA port on your PC.

4. Make sure both connections are secure.

Attention

This device must be connected to an off-the-shelf video cable in order to comply with FCC
regulations. A ferrite-core interface cable is included in the LCD Monitor package.
This device will not be in compliance with FCC regulations when a non-ferrite-core video
cable is used.

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’re in MS-Windows environment.

2. Check the screen to see if there’s any black vertical strip es 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. M ake 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”.
