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 Video 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 Video cord be used.

Important Safety Instructions
Please read the following instructions carefully. This manual should be retained for future use.
1. To clean LCD Monitor screen;
-- Power off LCD Monitor and unplug the AC Cord.
-- Spray a non-solvent cleaning solution onto a rag.
-- Gently clean the screen with dampened rag.
2. Do not place the LCD Monitor near a window. Exposing the monitor to rain water, moisture or sunlight can
severely damage it.
3. Connect all cables to the back of the LCD Monitor.

5. Do not remove the cover or attempt to service this unit by yourself. Servicing of any nature should be
performed by an authorized technician.
6. Store LCD Monitor in a room with a room temperature of -20° ~ 60°C (or -4° ~ 140°F). Storing the LCD
Monitor outside this range could result in permanent damage.
7. If any of the following occurs, immediately unplug your monitor and call an authorized technician.
* Monitor to PC signal cable is frayed or damaged.
* Liquid spilled into LCD Monitor or the monitor has been exposed to rain.
* LCD Monitor or the case is damaged.
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 * User's Manual
* 1.5M Monitor-to-PC signal Cable * AC Adapter
* 1.5M Stereo Jack Audio Cable * 1.8M Power Cord
If you find that any of these items is missing or appears damaged, contact your dealer immediately.
Viewing Angle Adjustment
The LCD Monitor is designed to allow users to have a comfortable
viewing angle. The viewing angle can be adjusted as follows: Top
(-5°~ +15°) & Left / Right (-45° to +45°).
sWarning : 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.
Figure 1-1
Detaching LCD Monitor from Its Stand
1. Remove the rear panel (1) from the monitor.
(see Fig. 1-2)
2. Remove the rear support panel (2) from the
swivel base support column.
3. Unscrew screws (3) the swivel base support
column (4).

Interface for Arm Applications
Before connecting the display to the swivel base support column,
please refer to Fig.1-2.
The rear of this LCD display has four integrated 4 mm, 0.7 pitches
threaded nuts, as well as four 5 mm access holes in the plastic
covering as illustrated in Figure 1-3. These specifications 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
Cable Installation
Please follow these instructions to install the cables. (See Fig. 1-4)
1. Remove the back panel (1) from the rear of the monitor.
2. Remove the rear support panel (2) from the swivel base support
column
3. Place the signal cable, the DC power cable and the audio cable
into their correct respective grooves (3).
Figure 1-4
Connecting the Display to your Computer
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 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.
Figure 1-5
Connecting the AC Power
1. Connect the power cord to the AC adapter. (See Fig. 1-6)
2. Connect the AC adapter's DC output connector to the DC Power
Jack of the monitor.
3. Connect the power cord to an AC power source.
Warning: We recommand to install a "Surge Protector" device between
the AC Adapter and the electrical wall outlet for adding protection against
power surges to prevent the effects of sudden voltage variations from
reaching the LCD Monitor. Sudden power surges may damage your
monitor.
Figure 1-6
Connecting the Audio Cable
1. Connect the audio cable to the " LINE OUT " jack on your PC's
audio card or to the front panel's “AUDIO OUT” jack of your CD
ROM drive. (See Fig. 1-7)
2. Connect the other end of the audio cable to the LCD Monitor's "
LINE IN " jack.

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 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 ~ 80 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”.
