IMPORTANT SAFETY INSTRUCTIONS

READ INSTRUCTIONS - All safety and oper-

ating instructions should be read before the
DTT2500 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 Power Supply

Adapter 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

Decoder Amplifier 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 DTT2500

Digital Decoder Amplifier on an unstable
cart, stand, tripod, bracket, or table. The
Decoder Amplifier 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 Sound-Works,
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

Decoder Amplifier are provided for venti­lation and to ensure reliable operation of
the Decoder Amplifier and to prevent it
from overheating. 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 Decoder Amplifier 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 Decoder Amplifier should be

situated away from heat sources such as
radiators, heat registers, stoves, and other
products (including amplifiers) that pro­duce heat.

POWER SOURCES - The Decoder Amplifier

should be operated only from the type of
power source indicated on the marking
label. If you are not sure of the type of
power supply to your home, consult your
product dealer or local power company.
For products intended to operate from
battery power, or other sources, refer to
the operating instructions.

POLARIZATION - The power supply may be

equipped with a polarized alternating-cur­rent 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, try 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 sup-

ply cords should be routed so that they are
not likely to be walked on or pinched by
items placed upon or against them, paying
particular attention to cords at plugs, con­venience receptacles, and the point where
they exit from the Decoder Amplifier.

LIGHTNING - For added protection for the

DTT2500 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 Decoder Amplifier due to light­ning and power-line surges.

OVERLOADING - Do not overload wall out-

lets, extension cords, or integral conve­nience receptacles as this can result in a
risk of fire or electric shock.

OBJECT AND LIQUID ENTRY - Never push

objects of any kind into the Decoder Am­plifier through openings as they may touch
dangerous voltage points or short out parts
that could result in a fire or electric shock.
Never spill liquid of any kind on the speak­ers or the Decoder Amplifier.

SERVICING - Do not attempt to service the

any part of the DTT2500 Digital yourself
as opening or removing covers may ex­pose you to dangerous voltage or other
hazards. Refer all servicing to qualified
service personnel.

DAMAGE REQUIRING SERVICE - Unplug

the power supply from the wall outlet or
other power source and refer servicing to
qualified service personnel under the fol­lowing conditions:
a) When the power supply cord or plug is
damaged.
b) If liquid has been spilled, or objects
have fallen into the subwoofer.
c) If the Decoder Amplifier has been ex­posed to rain or water.
d) If the subwoofer does not operate nor­mally by following the operating instruc­tions; or exhibits a distinct change in per­formance.
e) If the product has been dropped or
damaged in any way.

REPLACEMENT PARTS - When replace-

ment parts are required, be sure the ser­vice technician has used replacement
parts specified by Cambridge SoundWorks
or have the same characteristics as the
original parts. Unauthorized substitutions
may result in fire, electric shock, or other
hazards.

SAFETY CHECK - Upon completion of any

service or repairs to the DTT2500 Digital
system, ask the service technician to per­form safety checks to determine that the
DeskTop Theater 5.1 system is in proper
operating condition.

WALL OR CEILING MOUNTING - The

DTT2500 Digital satellites should be
mounted to a wall or ceiling only as rec­ommended by Cambridge SoundWorks.
