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 at least 20 cm of space 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.
• Do not cover the rear panel of this unit with a newspaper, a
tablecloth, a curtain, etc., in order not to obstruct heat

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.
