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 plasma screen panel of the monitor
Before cleaning the monitor, turn off the monitor and disconnect the power plug from the power outlet.
To prevent scratching or damaging the plasma screen face, do not knock or rub the surface with sharp or hard objects. Clean the screen with
a soft cloth moistened with warm water and dry with a soft cloth. If it is not enough, then use a cloth with mild detergent. Do not use harsh or
abrasive cleaners.
• How to clean the cabinet of the monitor
Use a soft cloth to clean the cabinet and control panel of the monitor. When excessively soiled dilute a neutral detergent in water, wet and
wring out the soft cloth and afterward wipe with a dry soft cloth.
Never use acid/alkaline detergent, alcoholic detergent, abrasive cleaner, powder soap, OA cleaner, car wax, glass cleaner, etc. especially
because they would cause discoloration, scratches or cracks.
CAUTION
Be careful in moving the monitor.
Neglect could result in an injury or damage.
• Do not move the monitor during use. Before moving, disconnect the power plug and all external connections.
• You are advised to move the monitor with two persons.
• Avoid any impact or shock to the monitor; particularly take care of glass screen.
Do not put anything on top of the monitor.
Placing anything on the monitor could result in loss of balance or falling, and cause an injury or damage. Use special caution in
households where children are present.
Avoid a humid or dusty place.
Placing the monitor in a smoke, a highly humid, dusty place, oily soot or corrosive gas could result in fire or electrical shock.
• Do not place near the kitchen, a humidifier or other place where there is oil, smoke or humidity.
Avoid a high temperature environment.
The heat could have adverse influence on the monitor and other parts, and could result in transformation, melting or fire.
• Do not place the monitor, the remote control and other parts in direct sunlight or near a hot object such as heater, etc.
• Do not put the monitor in a place where the temperature is widely changing.
Doing so could cause the unit to tip over or become damaged, causing injury.
Be especially careful in households with small children.
• Although the product has a hook to prevent tipping, leaning items against it could tip the unit over, causing injury.
Remove the power cord for complete separation.
• For safety purposes, disconnect the power cord if the monitor is not to be used for prolonged periods of time.
• Before cleaning, turn off and unplug the monitor. Neglect could result in fire or electrical shock.
