before the DTT3500 Digital amplified
subwoofer/satellite system is operated.
RETAIN INSTRUCTIONS - The safety and
operating instructions should be retained
for future reference.
HEED WARNINGS - All warnings on the
subwoofer and in the operating instructions
should be adhered to.
FOLLOW INSTRUCTIONS - All operating and
use instructions should be followed.
CLEANING - Unplug the subwoofer from the
wall outlet or other power source before
cleaning. Do not use liquid cleaners or aerosol
cleaners. Use a damp cloth for cleaning.
ATTACHMENTS - Do not use attachments not
recommended by Cambridge SoundWorks
as they may cause hazards.
WATER AND MOISTURE - Do not use the
subwoofer near water—for example, near a
bath tub, wash bowl, kitchen sink, or
laundry tub; in a wet basement; or near a
swimming pool; and the like.
ACCESSORIES - Do not place the DTT3500
Digital system on an unstable car t, stand,
tripod, bracket, or table. The subwoofer or
satellites may fall, causing serious injury to
a child or adult, and serious damage to the
product. Use only with a cart, stand, tripod,
bracket, or table recommended by
Cambridge SoundWorks, or sold with the
product. Any mounting of the satellites or
subwoofer should follow the
manufacturer’s instructions, and should use
a mounting accessory recommended by
Cambridge SoundWorks.
VENTILATION - Slots and openings in the

ensure reliable operation of the subwoofer
and to prevent it from overheating; and
these openings must not be blocked or
covered. The openings should never be
blocked by placing the product on a bed,
sofa, rug, or other similar surface. The
subwoofer should not be placed in a built-in
installation such as a bookcase or rack
unless proper ventilation is provided or
Cambridge SoundWorks’ instructions have
been adhered to.
HEAT - The subwoofer should be situated
away from heat sources such as
radiators, heat registers, stoves, and
other products (including amplifiers) that
produce heat.
POWER SOURCES - The subwoofer should
be operated only from the type of power

or local power company. For products
intended to operate from battery power or
other sources, refer to the operating
instructions.
POLARIZATION - The subwoofer may be
equipped with a polarized alter natingcurrent line plug (a plug having one blade
wider than the other). This plug will fit into
the power outlet only one way. This is a
safety feature. If you are unable to insert
the plug fully into the outlet, tr y reversing
the plug. If the plug should still fail to fit,
contact your electrician to replace your
obsolete outlet. Do not defeat the safety
purpose of the polarized plug.
POWER-CORD PROTECTION - Power-supply

where they exit from the subwoofer.
LIGHTNING - For added protection for the
DTT3500 Digital system during a lightning
storm, or when it is left unattended and
unused for long periods of time, unplug it
from the wall outlet. This will prevent
damage to the subwoofer due to lightning
and power-line surges.
