Care for the Surface
You should periodically wipe the speakers with a soft, dry cloth.
For stubborn stains, remove it by using a soft cloth dampened
with water and a mild detergent, then wipe it dry with a dry cloth.
Do not use a rough cloth, thinners, alcohol, or other volatile
solvents. When you use wipes, please refer to a note of caution
supplied with the wipes. For mirror-smooth finish type, use a
commercially available piano cleaner (a polish for smooth finish).
The cleaner remove the hand marks and stains, and give a luster
to the surface. The cleaner also prevents the hand marks and
stains, and make it easier to remove them with a dry cloth. You
can dust the grille net of the speaker by using a vacuum cleaner or
blush.

extremely sensitive and can be affected even by the magnetism of
the earth. If a speaker system is used near them, therefore,
discoloring or distortion of pictures will occur.
This speaker is not provided with magnetic shielding.
If
discoloration or distortion occurs, move the speaker apart from
the television set.
