SAFETY WARNINGS AND GUIDELINES
Please read this entire manual be for e us e, paying extra attention to these safety
warnings and guidelines. Please keep this manual in a safe place for future reference.
• This device is intended for indoor use only.
• Do not expose this device to water or moisture of any kind. Do not place drinks or
other containers with moisture on or near the device. If moisture does get in or on
the device, immediately unplug it from the power outlet.
• If operating this speaker in a humid environment, ensure that no condensation
occurs. Condensation could cause damage to the speaker cone and could cause
a short in the subwoofer's amplifier, which in turn could cause fire or severe
electric shock.
• Use only in a well-ventilated area. Do not use in close, confined spaces.
• Do not expose this device to excessively high temperatures. Do not place it in,
on, or near heat sources, such as a fireplace, stove, radiator, etc. Do not leave it
in direct sunlight.
• The power supply for this subwoofer uses a NEMA 5-15 three prong, grounded
plug. Do not use a "cheater" plug or otherwise bypass the grounding pin.
• Disconnect the unit from the power source when replacing the fuse. Replace the
fuse only with the same type or an exact equivalent.
• Unplug this device from the power source when not in use.
• Prior to operation, check the unit and power cor d for phy s ical damage. Do not
use if physical damage has occurred.
• Before plugging the unit into a power outlet, ensure that the outlet provides the
same type and level of power required by the device, as determined by the
Voltage Selection switch on the rear panel.
• Do not allow the power cord to be crimped, pinched, stepped on, etc. Ensure that
the power cord does not present a tripping hazard.
• Ensure that power is turned off and disconnected before making any electrical
connections.
• When disconnecting the power cord, do not pull on the cord itself. Instead, grasp
the plug connector head to discon nec t it fro m the power socket.
• Do not bypass the purpose of the fuse by shorting the contacts or by any other
means. If the fuse blows or breaks, replace it with the type specified for your
mains voltage in the Specifications section of this manual.
• Clean only using a soft, dry cloth. Do not use chemical cleaners, solvents, or
detergents. For stubborn deposits, moisten the cloth with warm water.

• This device has no user serv i ceable parts. Do not attempt to open, service, or
modify this device.
• Do not pick up or carry the subwoofer by grasping the ports on the fr ont.
• When picking up the subwoofer, take care not to touch the exposed speaker
cone on the front of the unit.
• Double-check all connections prior to applying power to ensure that speaker
polarity is properly matched and that there are no stray wire strands, which could
short the connections, either on the back of the speaker or the receiver/amplifier.
• Do not use full volume until after the subwoofer has been fully broken-in.
• If you hear distortion, reduce the volume until the distortion is no longer audible.
Distortion can sound like a buzzing, scratching, or hammering sound. Distortion
can damage or destroy delicate speaker coils.
• To avoid annoying feedback, ensure that any turntable is isolated from the
vibrations produced by this subwoofer.
• Extreme volume in the bass frequencies can distort the image on a nearby
television. If this occurs, move the subwoofer further away from the TV.
