CAUTION: READ THIS BEFORE OPERATING YOUR UNIT. (continued)
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 display 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 display panel 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 the plasma monitor is 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.
Prevention of an obstacle to Radio receivers
This monitor has been designed pursuant to the international EMI standards. This is to prevent a problem to Radio receivers.
• Keep the monitor away from Radio.
• Adjust Radio antennas in order for the monitor not to receive interference.
• The antenna cable of Radio should be kept away from the monitor.
• Use a coaxial cable for antenna.
You can check if this monitor influences Radio receivers by turning off all other equipment other than the monitor.
If you find a problem receiving Radio when using the monitor, check the instructions mentioned above.
Precautions for the cable connection
• Do ensure that all connections, (including the power plug, extension leads and interconnections between the pieces of equipment), are
properly made and in accordance with the manufacturers instructions. Switch off and withdraw the power plug before making or changing
connections.
• Confirm the connector is fixed tightly when the signal cable is connected.
Also confirm the screws on the connector are tightened.
• Plug the power cord of the monitor into a different socket from that for other equipment, such as Radio etc.
• Use a plug with ground terminal and make sure that it connects to the ground.
Precaution during transportation
Please pay attention when you transport this monitor because it is heavy.
Furthermore, use the original carton box and its packaging materials when the monitor is transported.
Failure to transport the monitor in any carton except the original carton may result in damage to the monitor.
Save the original carton box and all packing material.
Do not physically impact the remote control.
A physical impact could cause damage or malfunction of the remote control.
• Take care not to drop the remote control.
• Do not place heavy objects on the remote control.
Avoid strong rays.
Any strong rays (such as direct sun rays or room lighting) onto the remote control sensors could invalidate the remote control.
Avoid radio interference.
Any interfering radiation could cause distorted images or noises.
• Avoid radio generator such as a mobile telephone, transceiver, etc. around the monitor.
Set the sound volume at a suitable level.
It is better to keep the volume level low and close the windows at night to protect the neighborhood environment.
