Observe the folowing safety guidelines when connection and using your monitor: Be sure that your monitor is electrically rated to operate with the AC power available in your location. Locate your monitor near an easily accessible electrical outlet. Place the monitor on a solid surface and treat it carefully. The screen can be damaged if dropped, sharply hit, or touched with a sharp or abrasive implement. Put your monitor in a location with low humidity and a minimum of dust. Never use your monitor if the power cable has been damaged. Do not allow anything to rest on the power cable, and keep the cable away from where people could trip over it. Never insert anything metallic into the monitor openings. Doing so may create the danger of electric shock. To avoid electric shock, never touch the inside of the monitor. Only a qualified technician should open the monitors case. Be sure to hold the plug, not the cable, when disconnecting the monitor from an electrical outlet. Openings in the monitor cabinet are provided for ventilation. To prevent overheating, these openings should not be blocked or covered. Also, avoid using the monitor on a bed, sofa, rug, or other soft surface. Doing so may block the ventilation openings in the bottom of the cabinet. If you put the monitor in a bookcase or some other enclosed space, be sure to provide adequate ventilation. Do not expose the monitor to rain or use it near water. If the monitor accidentally gets wet, unplug it and contact an authorized dealer immediately. You can clean the exterior of the monitor with a damp cloth when necessary, but be sure to unplug the monitor first. If your monitor does not operate normally-in particular, if there are any unusual sounds or smells coming from it -unplug the monitor immediately and contact an authorized dealer or service center.
Connecting Your Monitor to a Computer
1.Connect Video Cable a. Make sure both the monitor and computer are powered-OFF. b. Connect the video cable to the computer. c. (only Dual-Input Model) Connect one end of the 24-pin DVI cable to the back of the monitor and connect the other end to the computers port. 2. Connect power cord Connect the power cord to the monitor, then to a properly grounded AC outlet. 3. Connect the Audio Cable.(optional) 4. Power-ON Monitor and Computer Power-ON the monitor first, then power-ON the computer. This sequence is very important. 5. If the monitor still does not function properly, please refer to the troubleshooting section to diagnose the problem.

SPECIAL NOTES ON LCD MONITORS
The following symptoms are normal with LCD monitor and do not indicate a problem.

Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the Power Switch and then turn it on again to make sure the flicker disappears. You may find slightly uneven brightness on the screen depending on the desktop pattern you use. The LCD screen has effective pixels of 99.99% or more. It may include blemishes of 0.01% or less such as a missing pixel or a pixel lit all of the time. Due to the nature of the LCD screen, an afterimage of the previous screen may remain after switching the image, when the same image is displayed for hours. In this case, the screen is recovered slowly by changing the image or turning off the Power Switch for hours.

Tips and information for comfortable use
Computer users may complain of eyestrain and headaches after prolonged use. Users are also at risk of physical injury after long hours of working in front of a computer. Long work periods, bad posture, poor work habits, stress, inadequate working conditions, personal health and other factors greatly increase the risk of physical injury. Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis, tenosynovitis or other musculoskeletal disorders. The following symptoms may appear in the hands, wrists, arms, shoulders, neck or back: numbness, or a burning or tingling sensation aching, soreness or tenderness pain, swelling or throbbing stiffness or tightness coldness or weakness If you have these symptoms, or any other recurring or persistent discomfort and/or pain related to computer use, consult a physician immediately and inform your companys health and safety department. The following section provides tips for more comfortable computer use.

Finding your comfort zone
Find your comfort zone by adjusting the viewing angle of the monitor, using a footrest, or raising your sitting height to achieve maximum comfort. Observe the following tips: refrain from staying too long in one fixed posture avoid slouching forward and/or leaning backward stand up and walk around regularly to remove the strain on your leg muscles
take short rests to relax your neck and shoulders avoid tensing your muscles or shrugging your shoulders install the external display, keyboard and mouse properly and within comfort able reach if you view your monitor more than your documents, place the display at the center of your desk to minimize neck strain
Taking care of your vision
Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive room lighting, poorly focused screens, very small typefaces and low-contrast displays could stress your eyes. The following sections provide suggestions on how to reduce eyestrain. Eyes Rest your eyes frequently. Give your eyes regular breaks by looking away from the monitor and focusing on a distant point. Blink frequently to keep your eyes from drying out. Display Keep your display clean. Keep your head at a higher level than the top edge of the display so your eyes point downward when looking at the middle of the display. Adjust the display brightness and/or contrast to a comfortable level for enhanced text readability and graphics clarity. Eliminate glare and reflections by: placing your display in such a way that the side faces the window or any light source minimizing room light by using drapes, shades or blinds using a task light changing the displays viewing angle using a glare-reduction filter using a display visor, such as a piece of cardboard extended from the displays top front edge Avoid adjusting your display to an awkward viewing angle. Avoid looking at bright light sources, such as open windows, for extended periods of time.
Developing good work habits
Develop the following work habits to make your computer use more relaxing and productive: Take short breaks regularly and often. Perform some stretching exercises. Breathe fresh air as often as possible. Exercise regularly and maintain a healthy body. ----------------------------------------------------------------------------------------------------Warning! We do not recommend using the product on a couch or bed.

CONNECTING THE POWER CORD
Check first to make sure that the power cord you use is the correct type required for your area. This monitor has a universal power supply that allows operation in either 100/120V AC or 220/240 V AC voltage area. No user-adjustment is required. Plug one end of the power cord to the AC Inlet, plug another end to a proper AC outlet. For unit using at 120 V AC: Use a UL Listed Cord Set, Type SVT wire and plug rated 10 A/125 V. For unit using at 220/240 V AC (outside of U.S.): Use a Cord Set consisting of H05VV-F cord and plug rated 10 A, 250 V. The cord set should have the appropriate safety approvals for the country in which the equipment will be installed.

SAFETY PRECAUTION

Avoid placing the monitor, or any other heavy object, on the power cord to avoid damage to the cable. Do not expose the monitor to rain, excessive moisture, or dust. Do not cover the ventilation slots or openings of the monitor. Always put the monitor in a place where there is adequate ventilation. Avoid placing the monitor against a bright background or where sunlight or other light sources may reflect on the face of the monitor. Place the monitor just below eye level. Handle with care when transporting the monitor. Refrain from giving shock or scratch to the screen, as screen is fragile.

CLEANING YOUR MONITOR

Please carefully follow the below guidelines when cleaning the monitor. Always unplug the monitor before cleaning. Use a soft cloth to wipe the screen and cabinet front and sides.

Power saving

The monitor will be driven into Power Saving mode by the control signal from the display controller, as indicated by the amber-color power LED. State ON Power Saving Mode LED Light Blue Amber

To make your installation easier, the monitor is able to Plug and Play with your system if your system also supports DDC protocol. The DDC (Display Data Channel) is a communication protocol through which the monitor automatically informs the host system about its capabilities, for example, supported resolutions and corresponding timing. The monitor supports DDC2B standard.
