Periodical maintenance is recommended to improve the service life and performance of the system. In the
maintenance, clean the system equipment as described in the following.
a) Plasma display monitor, scan device, remote control unit and special pen
Never use solvents such as benzene or thinner, which can damage or destroy the coating on the main unit, the remote
control unit and the special pen.
Remove dirt by lightly wiping with a soft cloth.
If necessary, slightly moisten the cloth with neutral detergent, diluted with water. In humid conditions, wipe off
condensation with a dry cloth.
b) Screen
After removing dust, wipe gently with the provided cloth (Wiping Cloth) or a dry soft cloth. Do not rub with tissue paper
or hard abrasive materials.
Never use solvents such as benzene or thinner, which can discolor the screen or render it opaque.
For cleaning, we recommend the following cloth and fluid.
For light soiling, brush off dust and lightly wipe with Minimax. In case of heavy soiling, brush off dust, then wipe with
Minimax with its corner lightly moistened with B4. Be sure to wipe with dry Minimax after B4 dries out as there may be
unevenness remaining otherwise.
c) Vents
Every month, remove dirt from the vent on the rear of the main unit, using a vacuum cleaner set to its lowest suction
setting. Blocked vents can lead to dangerously high internal temperatures, resulting in malfunctions or fire.

d) Readjustment of White Balance
The unit uses phosphor elements, as do CRTs. These phosphors degrade over time, reducing brightness. Since green
and blue phosphors degrade faster than red, we recommend readjusting the white balance every 1000 hours.
For information on how to adjust white balance, refer to the Operating Instructions supplied with the plasma display.
