ENGLISH SAFETY GUIDELINES(continued) CAUTION You may have serious injury or your property may be damaged unless you follow the instruction below. • Do not coil or wind the power cord. This may cause excessive heat resulting in a fire. • Caution for 200 - 240V operation only This equipment relies on the protective devices in the building installation for short - circuit and over - current protection. Refer to the following table for the suitable number and location of the protective devices which should be provided in the building installation. INFORMATIVE EXAMPLES OF PROTECTIVE DEVICES IN SINGLE - PHASE EQUIPMENT OR SUB - ASSEMBLIES Case A: Equipment to be connected to POWER SYSTEMS with earthed neutral reliably identified, except for Case C below. Case B: Equipment to be connected to any supply, including IT POWER SYSTEMS and supplies with reversible plugs, except for Case C below.

For complete isolation from the mains, remove the power cord from the monitor or from the wall socket. PRECAUTIONS • Installation environment Do not obstruct a ventilation hole. Do not put the monitor on carpet or blanket, or near a curtain which has a possibility of obstructing a ventilation hole of the monitor. Do not put the monitor in the following places. • Hot places such as near heater, place exposed to the direct rays of the sun. • A place where the temperature is widely changing. • Places with soot, dust or high humidity. • Poor air ventilation place. • Place near fire. • A wet place such as bathroom, or shower room. • Place where you can trip over it. • Always vibrating or strongly vibrating places. • Distorted or unstable places. • How to view the monitor. If you use the monitor in too dark a room, your eyes may become tired. Please use it in a reasonably bright room. Avoid direct rays of the sun to the screen in order to prevent eye fatigue. Your eyes will get fatigued after viewing the monitor for long period of time. Relax your eyes by viewing away from the monitor from time to time. Please watch the monitor in downward direction. • Note on image retention The plasma monitor illuminates phosphor to display images. The phosphor has a finite illumination life. After extended periods of illumination, the brightness of the phosphor would be degraded to such extent that still images would image retention that part of the screen as grayed-out images. Tips to prevent such image retention are: - Do not display images having sharp brightness differences or high-contrast images, such as monochrome characters and graphic patterns, for long. - Do not leave stationary images appearing for long, but try to refresh them at appropriate intervals of time, or try to move them using screen saver function. - Turn down the contrast and brightness controls.
