Precautions
On safety
 Before operating the subwoofer, be sure that the operating voltage of the subwoofer is
identical with that of your local power supply.
 Unplug the subwoofer from the wall outlet if it is not to be used for an extended period of
time. To disconnect the cord, pull the cord by grasping the plug. Never pull the cord
itself.
 Should any liquid or solid object fall into the subwoofer, unplug it and have it checked by
qualified personnel before operating it any further.
 The AC power cord must be changed only at a qualified service shop.
When turning on or off an amplifier or other equipment
Lower the volume of the amplifier to minimum.
To avoid damaging the subwoofer
 Be careful in setting the volume control of the amplifier to avoid excessive input power.
 Do not disassemble or modify the woofer unit or enclosure.
 Do not press the dust cap intentionally or unintentionally.
When howling occurs
Relocate the subwoofer or turn down the volume of the amplifier.
Cleaning of the enclosure
 Do not use any type of neutral detergent, benzene, or alcohol because they may damage
the surface finish of the enclosure.
 To maintain the fine gloss of the enclosure for a long time, gently wipe off dust using a
soft brush or feather duster, and then wipe the enclosure with the supplied cleaning cloth.
(Do not use any type of scrub brush or sponge.)
 Wipe smudges such as fingerprints or oil spots with the supplied cleaning cloth carefully.
 When the smudges are hard to remove, wipe them off with a soft cloth soaked in soapy
water, and wrung dry.
 Make sure not to damage the enclosure.
 The supplied cleaning cloth is washable and can be used repeatedly.

Troubleshooting
If you experience any of the following difficulties while using the subwoofer, use this
troubleshooting guide to help you remedy the problem. Should any problem persist,
consult your nearest Sony dealer.
There is no sound.
 Check that this subwoofer and components are connected correctly and securely.
 Turn LEVEL clockwise to turn up the volume.
The sound has suddenly stopped.
 The speaker cords may have short-circuited. Connect the cords properly.
 If the input signal is too high, the limiter turns off the sound (the POWER indicator
blinks red). Turn the power off, then on again.
The sound is distorted.
 The input signal is imperfect.
 The input signal level is too high.
Severe hum or noise is heard.
 If using a turntable, connect the ground wire of the turntable properly.
 The contacts between the plugs of the audio connecting cords (not supplied) or the
speaker cords (not supplied) and the corresponding jacks have not been made properly.
Connect the plugs firmly.
 The audio system is picking up some noise from a TV. Move the audio system away
from the TV or turn the TV off.
 If the subwoofer and amplifier are connected via speaker cords, hum or noise can be
improved by connecting the LINE IN jack of the subwoofer to an unused input jack of
the amplifier via an audio connecting cord.
