Warnings, Cautions and Others

Precautions for installation

• Do not install the speakers on an uneven surface or in a place

subject to vibration; otherwise, they may fall over, causing
damage or injury.
– Take the occurrence of earthquakes or other

physical shocks into consideration when
selecting the installation place, and secure the
speakers thoroughly.

• To prevent deformation or discoloration of the

cabinet, do not install the speakers where they
are exposed to direct sunlight or high humidity,
and avoid installation near air conditioning
outlets.

• Speaker vibrations may cause howling. Place the

speakers as far away from the player as possible.

• The speakers are magnetically shielded to avoid color

distortions on TVs. However, if not installed properly, it may
cause color distortions. So, pay attention to the following when
installing the speakers.
– When placing the speakers near a TV set, turn off the TV’s

main power switch or unplug it before installing the
speakers.
Then wait at least 30 minutes before turning on the TV’s
main power switch again.

Some TVs may still be affected even though you have followed
the above. If this happens, move the speakers further away
from the TV.

Precautions for Daily Use

• To maintain the appearance of the speakers

Wipe with a dry, soft cloth if the cabinet or control panel
should become dirty.
If very dirty, apply a small amount of water or neutral
detergent to the cloth and wipe clean, then wipe with a dry
cloth.

• To improve the sound field

If the speakers are facing a solid wall or glass
door, etc., it is recommended to furnish the wall
with materials that absorb sounds, for example
by hanging up thick curtains, to prevent
reflections and standing waves.

• To use the speakers without any trouble

– Do not reproduce sounds at so high a volume that they are

distorted; otherwise, the speakers may be damaged by
internal heat buildup.

– When moving the speakers, do not pull the speaker cords;

otherwise, the speakers may fall over, causing damage or
injury.

carefully to be sure you get the best possible performance. If you
