cleaners. Use a damp cloth for cleaning.

ATTACHMENTS - Do not use attachments not

recommended by Cambridge Soundworks
and Creative Technology, as such items
may cause hazards.

bath tub, wash bowl, kitchen sink, or
laundry tub; in a wet basement; or near a
swimming pool; and other similar
conditions.

MegaWorks THX 250D system on an
unstable cart, 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 and Creative Technology, 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 and Creative
Technology.

VENTILATION - Slots and openings in the

cabinet are provided for ventilation, to
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

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 alternating­current line plug (a plug having one blade
wider than the other). This plug will fit into

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.
