• Remove the plug from the plug socket before maintenance.
• Maintenance of the cabinet/remote controller
Do not use solvent such as benzene and thinner. The cabinet and remote controller may deteriorate in quality or the
paint may peel off.
Use a soft cloth to wipe off dust lightly.
When they are very dirty, put a soft cloth in detergent diluted with water, fully wring it and wipe with it. Finish
cleaning with a dry soft cloth.
• Maintenance of screen (protective front panel)
The screen (protective front panel) surface is treated by special coating to prevent reflection. This causes the panel to be very
delicate. Use a dry soft cloth for maintenance after wiping dust off. Do not wipe it with tissue paper or hard paper.
Do not use solvent such as benzen and thinner to maintain this panel. Using solvent may result in discoloration of the panel.
We recommend cleaning cloth and cleaning liquid.
Name
Cleaning cloth: MiniMax
Cleaning cloth: Wiping cloth
Cleaning liquid: B4
If the panel is slightly dirty, brush any dust off the panel and lightly wipe with a Mini Max or Wiping Cloth.
If the panel it is very dirty, brush any dust off the panel, and then apply a small amount of B4 to the edge of a Mini
Max or Wiping Cloth and clean the dirty panel. In this state, the surface of the panel is unevenly cleaned. When the
B4 is dry, rub the surface with a dry Mini Max or Wiping Cloth.

Care and cleaning of ventilating holes
Remove with a vacuum cleaner set to 'LOW' the dust that gathered in the side slits of the main body and the ventilating
holes on the backside (See the above figure) at least once a month as a rule of thumb. Moreover, for maintenance of
ventilating holes, make sure to turn OFF the main body power supply switch.
Cautions:
In case the device is operated without removing accumulated dust, the temperature inside the device will abnormally
increase, resulting in failures.
Make sure to regularly clean the ventilating holes.
• Readjusting white balance
This device uses phosphor as with CRT, and if it is used for a long period of time, it is likely that phosphor deteriorates
and luminance decreases. Since green and blue phosphors are likely to deteriorate slightly earlier than red phosphor,
we recommend you to readjust the white balance every 1,000 hours.
