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.

by an authorized technician.
5. 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.
6. 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.
7. A certified line is required to connect this device to a power outlet. For a nominal current up to 6A and a device
weight above 3 kg, a line not lighter than H05VV-F, 3G, 0.75 mm

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
* 1.8M Monitor-to-PC VGA Cable * AC Adapter
* 1.8M Monitor-to-PC DVI-D Cable * 1.8M Power Cord
* 1.5M Stereo Jack Audio Cable
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 from -5°to
+25°.(See fig. 1-1)& Left / Right -45° to +45°
Warning: Do not force the LCD Monitor over its maximum viewing angle settings as stated above.
Figure 1-1
Attempting this will result in damaging the Monitor and Monitor stand.

Interface for Arm Applications
Before installing to mounting device, 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.
1. Remove the back panel n from the rear of the monitor.(See Fig. 1-4)
2. Place the signal cable, the DC power cable into their correct
respective grooves.
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
or DVI port.(See Fig 1-5)
3. Connect the other end of the signal cable to the VGA port or DVI port
on your PC.
4. Make sure connection 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
Figure 1-6
outlet for adding protection against power surges to prevent the errects of sudden voltage variations from
reaching the LCD Monitor. Sudden power surges may damage your monitor.
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.

the monitor (See Fig. 1-8)
2.
Turn on the LCD Monitor's soft power switch, located on the bezel of
the monitor.

Power Management System
This LCD Monitor complies with the VESA DPMS (version 1.0) Power Management guidelines. The VESA DPMS
provides four power saving modes through detecting a horizontal or vertical sync. signal.
When the LCD Monitor is in power saving mode, the monitor screen will be blank and the power LED indicator will
light yellow.

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
9
Input Signal”.
