CAUTION
To assure ventilation, observe the following points
when installing the unit.
• Leave a distance of more than 10 cm between the
Subwoofer back and the surrounding wall(s). Use
special care not to cover the heat sink with a curtain,
etc. when installing.
• Do not place the equipment onto a bed, a sofa, a
carpet, or similar. Sucked-in dust can cause fi re.
• Be sure to install the Subwoofer vertically.
Vertical installation
Howling
If the Subwoofer is installed near an analog record
turntable, a howling sound may be generated. If
this occurs, place the Subwoofer farther away from
the turntable or reduce the Subwoofer volume (By
rotating the VOLUME control counter clock-wise).
The howling phenomenon may also occur due to
cross interference with a cassette deck, compact
disc player, or Laserdisc player, although this is very
rare. If sound or picture seems to be distorted due
to this reason, place the Subwoofer farther away
from other components or reduce its volume.
Operation near a TV
If the Subwoofer is installed near a TV set, the TV
reception may be a ected and interfered with color
irregularities. Should color irregularities observed
on TV screen, separate the Subwoofer from the TV
until its reception becomes normal.
