 Precautions for installation

• To prevent deformation or discoloration of the cabinet, do not

install the unit where it is exposed to direct sunlight or high
humidity, and avoid installation near air conditioning outlets.

• Speaker vibrations may cause howling. Place the unit as far

away from the player as possible.

• Take the occurrence of earthquakes or other physical shocks

into consideration when selecting the installation place, and
secure the unit thoroughly.

• Tuner reception may become noisy or hissing if this unit is

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

• The speakers are magnetically shielded to avoid color

distortions on TVs. However, if not installed properly, they 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 away from the
TV.

• When the TV screen shakes, move this unit away from the TV to

find a position where the screen doesn't shake and then set the
unit there.

 Precautions for Daily Use

• To maintain the appearance of the unit

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.
