Warnings, Cautions and Others

7

Precautions for installation

• To avoid personal injury or accidentally

dropping the unit, have two persons unpack,
carry, and install the unit.

• 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.

• Tuner reception may become noisy or hissing if a speaker is

installed near the tuner. In this case, leave more distance
between the tuner and the speakers or use an outdoor
antenna for better tuner reception without interference from
the speakers.

• Do not lean against the speakers, as the speakers could fall

down or break, possibly causing an injury. Especially be
careful that children do not lean against them.

7

 Precautions for daily use

• To maintain the appearance of the speakers

– Wipe with a dry, soft cloth if the cabinet should become

dirty.
If very dirty, wipe with a cloth applied a small amount of
water or neutral detergent, then wipe with a dry cloth.

– Do not use chemicals such as benzine and thinner for

cleaning the cabinet.

• To improve the sound field

– It is recommended to leave a space of more than 50 cm

between the speakers and the wall.

– 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.
