Installation Environment - Hitachi PD1 Handbuch

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 will
be degraded to such extent that stationary images would burn-in 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.
• How to clean the monitor.
Before cleaning the monitor, turn off the monitor and disconnect the power plug from the
mains.
When cleaning the monitor, do not spray directly the screen or cabinet with cleaner.
Use a clean, dust free, dry and soft cloth. If it is not enough, then use a cloth with non-
alcoholic or non-ammonia detergent.
Do not rub the surface of the screen with ball-point-pen or screw-driver etc.
