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
* 1.5M Monitor-to-PC signal Cable
* User's Manual
* 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°).
Figure 1-1
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.
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.
Figure 1-5
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.
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.
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.

Setting Up the LCD Monitor
1. Make sure the AC Adapter is connected to the LCD Monitor.
2. Turn on the LCD Monitor's 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 Input Signal”.
