Maintenance
First, remove the mains plug from the socket

Regular care
Gently wipe the surface of the display panel, cabinet
and pedestal by using a soft cloth.
Wipe the mains plug with a dry cloth at regular
intervals. Moisture and dust may lead to fire or
electrical shock.
For stubborn dirt
First clean the dust on the surface. Dampen a soft cloth
with clean water or diluted neutral detergent (1 part
detergent to 100 parts water). Wring the cloth and wipe
the surface. Finally, wipe away all the moisture.
Caution
Do not use a hard cloth or rub the surface too hard as
this could scratch the surface.
Do not subject the TV’s surfaces to water or detergent.
Liquid inside the TV could lead to product failure.
Do not subject the surfaces to insect repellent, solvent,
thinner or other volatile substances. This may degrade
surface quality or cause peeling of the paint.
The surface of the display panel is specially treated
and may be easily damaged. Take care not to tap or
scratch the surface with your fingernail or other hard
objects.
Do not allow the cabinet and pedestal to make contact
with a rubber or PVC substance for a long time. This
may degrade surface quality.
