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 holes in the  
plastic covering as illustrated in Figure 1-4.  
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 1-4  
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 both 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 Pow er  
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.  
Figure 1-6  
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.  
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.  
Pow er 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 youre 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 theres 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 doesnt 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.
