Refer all servicing to qualiﬁed service personnel.

•Do not spill any liquids into the cabinet or use your monitor near water.

•Do not insert objects of any kind into the cabinet slots, as they may touch dangerous voltage points, which can be harmful or fatal or may cause electric shock, ﬁre or equipment failure.

•Do not place any heavy objects on the power cord. Damage to the cord may cause shock or ﬁre.

•Do not place this product on a sloping or unstable cart, stand or table, as the monitor may fall, causing serious damage to the monitor.

•When operating the LCD monitor with an AC 100-120V power supply in North America, use a power supply cord provided with this monitor.

•When operating the LCD monitor with an AC 220-240V power supply in Europe, use a power supply cord provided with this monitor.

•In UK, use a BS-approved power cord with molded plug having a black (10A) fuse installed for use with this monitor.

If a power cord is not supplied with this monitor, please contact your supplier.

•When operating the LCD monitor with a 220-240V AC power supply in Australia, use the power cord provided with this monitor.

If a power cord is not supplied with this monitor, please contact your supplier.

•For all othercase, use a power cord that matches the AC voltage of the power outlet and has been approved by and complies with the safety standard of your particular country.

•Do not place any objects onto the monitor and do not use the monitor outdoors.

•The inside of the ﬂuorescent tube located within the LCD monitor contains mercury. Please follow the laws or rules of your municipality to dispose of the tube properly.

•Do not bend power cord.

•Do not use monitor in high temperature, humid, dusty, or oily areas.

•If monitor or glass is broken, do not come in contact with the liquid crystal and handle with care.

•Allow adequate ventilation around the monitor, so that heat can properly dissipate. Do not block ventilated openings or place the monitor near a radiator or other heat sources.

Do not put anything on top of the monitor.

•The power cable connector is the primary means of detaching the system from the power supply. The monitor should be installed close to a power outlet, which is easily accessible.

•Handle with care when transporting. Save packaging for transporting.

•Please clean the holes of back cabinet to reject dirt and dust at least once a year because of set reliability.

•If using the cooling fan continuously, it’s recommended to wipe holes a minimum of once a month.

•When installing the remote control batteries;

-Align the batteries according to the (+) and (-) indications inside the case.

-Align the (-) indication of the battery ﬁrst inside the case.

CAUTION:

Immediately unplug your monitor from the wall outlet and refer servicing to qualiﬁed service personnel under the following conditions:

•When the power supply cord or plug is damaged.

•If liquid has been spilled, or objects have fallen into the monitor.

•If the monitor has been exposed to rain or water.

•If the monitor does not operate normally by following operating instructions.

Recommended Use

CAUTION:

•For optimum performance, allow 20 minutes for warm-up.

•Rest your eyes periodically by focusing on an object at least 5 feet away. Blink often.

•Position the monitor at a 90° angle to windows and other light sources to minimize glare and reﬂections.

•Clean the LCD monitor surface with a lint-free, nonabrasive cloth. Avoid using any cleaning solution or glass cleaner!

•Adjust the monitor’s brightness, contrast and sharpness controls to enhance readability.

•Avoid displaying ﬁxed patterns on the monitor for long periods of time to avoid image persistence (after image effects).

•Get regular eye checkups.

Ergonomics

To realize the maximum ergonomic beneﬁts, we recommend the following:

•Use the preset Size and Position controls with standard signals.

•Use the preset Color Setting.

•Use non-interlaced signals.

•Do not use primary color blue on a dark background, as it is difﬁcult to see and may produce eye fatigue due to insufﬁcient contrast.
