Safety Precautions and Maintenance

FOR OPTIMUM PERFORMANCE, PLEASE NOTE THE FOLLOWING WHEN SETTING UP AND USING THE LCD4000 LCD COLOR MONITOR:

•DO NOT OPEN THE MONITOR. There are no user serviceable parts inside and opening or removing covers may expose you to dangerous shock hazards or other risks. 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 LCD4000 monitor with its AC 220-240V power supply, use a power supply cord that matches the power supply voltage of the AC power outlet being used. The power supply cord you use must have been approved by and comply with the safety standards of your country. (Type H05VV-F 3G 1mm2 should be used in Europe)

•In UK, use a BS-approved power cord with molded plug having a black (13A) fuse installed for use with this monitor. If a power cord is not supplied with this monitor, please contact your sup- plier.

•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.

•Do not bend power cord.

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

•If glass is broken, handle with care.

•Do not cover vent on monitor.

•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 any- thing on top of 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 follow the bylaws or rules of your municipality to dispose of the tube properly.

•Keep the holes on the back of the LCD clean of dirt and dust.

It is recommended to wipe holes with a soft cloth a minimum of once per year.

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 has been dropped or the cabinet damaged.

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

Recommended Use

CAUTION

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE FOLLOWING WHEN YOU POSITION THE MONITOR:

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

•Rest your eyes periodically by focusing on an object at least 20 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 and contrast controls to en- hance readability.

•Avoid displaying fixed patterns on the monitor for long peri- ods of time to avoid image persistence (afterimage effects).

•Get regular eye checkups.

•The lamp of backlight contains mercury. Please handle it ap- propriately in case of disposal.

Ergonomics

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

•Use the preset Size and Position controls with standard signals

•Use the preset Color Setting

•Use non-interlaced signals with a vertical refresh rate between 58-62Hz

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

contrast
