Preset Modes
To reduce the need for adjustment for different modes, the monitor has default setting modes that are most commonly used as given in the table below. For optimum adjustment, the user is suggested to perform the Auto Setup under Windows “Full Screen” pattern. When none of the mode is matched, the user can store their preferred modes in the user modes. The monitor is capable of storing up to 9 user modes. The only condition to store as a user mode is the new display information must have 1 kHz difference for horizontal frequency or 1 Hz for vertical frequency or the sync signal polarities are different from the default modes.

DDC (Display Data Channel)
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.

Safety Precautions and Maintenance
FOR OPTIMUM PERFORMANCE, PLEASE NOTE THE
FOLLOWING WHEN SETTING UP AND USING
THE 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 LCD monitor with its AC 125-240V 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 should be used in Europe)
•In UK, use a BS-approved power cord with molded plug having a black (5A) fuse installed for use with this monitor. If a power cord is not supplied with this monitor, please contact your supplier.
•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 bylaws or rules of your municipality to dispose of the tube properly.
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.
•Do not bend power cord.
•Do not use monitor in high temperatured, 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.
•
CAUTION •
•
Image Persistence
Image persistence is when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided.
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.
NOTE: As with all personal display devices, NEC-Mitsubishi Electronics Display recommends using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.
