Cleaning
Regular cleaning will extend the life and performance of the PD520. Before
cleaning, be sure to unplug the power cord from the power outlet.
Cleaning the Display
Panel Body and Remote
Control
Do not under any circumstances use solvents such as benzene or thinner to
clean the PD520. Doing so may cause deterioration or peeling of paint from the
display or remote control unit.
Wipe the display and remote control gently with a soft cloth. In case of
excessive dirt buildup, dampen a soft cloth with a diluted neutral cleaning
detergent. Wring the cloth thoroughly, then wipe the component and dry it with
a dry soft cloth.
Cleaning the Screen After dusting, wipe the screen gently using a soft cloth (cotton, flannel etc.). Do
not use tissue or coarse fabric. The screen surface is easily scratched; do not rub
it or hit it with a hard object.
If you clean the surface of the screen with a wet cloth, do not allow water
droplets on the surface to enter into the product; this may cause a malfunction.
Cleaning the Vents As a general rule, use a vacuum cleaner about once a month to clean the
vents on the rear panel of the display of dust buildup (set the vacuum cleaner
to its weakest setting when doing this). If not removed, accumulated dust can
cause the internal temperature to increase, resulting in possible breakdown or
fire.
