carefully. Keep it in a safe place for future reference.
● Install this unit in a cool, dry, clean place – away from windows,
heat sources, sources of excessive vibration, dust, moisture and
cold. Avoid sources of humming (transformers, motors). To
prevent fire or electrical shock, do not expose this unit to rain or
water.

● To reduce the risk or fire or electric shock, do not expose this
unit to rain or moisture.
● Do not use force on switches, controls or connection wires.
When moving the unit, first disconnect the power plug and the

themselves.
● When not planning to use this unit for a long period (ie.,
vacation, etc.), disconnect the AC power plug from the wall
outlet.
● To prevent lightning damage, disconnect the AC power plug
when there is an electric storm.
● Since this unit has a built-in power amplifier, heat will radiate
from the rear panel. Place the unit apart from the walls, allowing
enough spaces above, behind and on both sides of the unit to
prevent fire or damage. Furthermore, do not position with the
rear panel facing down on the floor or other surfaces.
<For U.K. and Europe models only>
Be sure to allow spaces of at least 20 cm above, behind and on
both sides of the unit.
● Do not cover the rear panel of this unit with a newspaper, a
tablecloth, a curtain, etc. in order not to obstruct heat radiation. If
the temperature inside the unit rises, it may cause fire, damage
to the unit and/or personal injury.
● Do not place small metallic objects on this unit. Otherwise, the
object may fall, possibly causing an injury.
● Do not place the following objects on this unit:
Glass, china, etc.
If glass etc. falls by vibrations and breaks, it may cause
personal injury.
A burning candle etc.
If the candle falls by vibrations, it may cause fire and personal
injury.
A vessel with water in it
If the vessel falls by vibrations and water spills, it may cause
damage to the unit, and/or you may get an electric shock.
● Do not place this unit where foreign objects such as water drips
might fall. It might cause a fire, damage to this unit, and/or
personal injury.
● Never open the cabinet. It might cause an electric shock since
this unit uses a high voltage. It might also cause personal injury
and/or damage to this unit.
● When using a humidifier, be sure to avoid condensation inside
this unit by allowing enough spaces around this unit or avoiding
excess humidification. Condensation might cause a fire, damage
to this unit, and/or electric shock.
● Super-bass frequencies reproduced by this unit may cause a
turntable to generate a howling sound. In such a case, move this
unit away from the turntable.
● This unit may be damaged if certain sounds are continuously
outputted at high volume level. For example, if 20 Hz–50 Hz sine
waves from a test disc, bass sounds from electronic instruments,
etc. are continuously outputted, or when the stylus of a turntable
touches the surface of a disc, reduce the volume level to prevent
this unit from being damaged.
● If you hear distorted noise (i.e., unnatural, intermittent “rapping”
or “hammering” sounds) coming from this unit, reduce the
volume level. Extremely loud playing of a movie soundtrack’s low
frequency, bass-heavy sounds or similarly loud popular music
passages can damage this speaker system.
● Vibration generated by super-bass frequencies may distort
images on a TV. In such a case, move this unit away from the TV
set
● Do not attempt to clean this unit with chemical solvents as this
might damage the finish. Use a clean, dry cloth.
● Be sure to read the “TROUBLESHOOTING” section regarding

Standby mode
When this unit is turned off by pressing the STANDBY/ON button
on the front panel, this unit consumes a small amount of power.
This state is called the standby mode. This unit’s power supply is
completely cut off from the AC line only when the POWER switch
on the rear panel is set in the OFF position or the AC power cable
is disconnected.
This unit features a magnetically shielded design, but there is
still a chance that placing it too close to a TV set might impair
picture color. Should this happen, move this unit away from the
TV set.
