this product.

SAFETY INSTRUCTIONS

• Never open the cabi net or remove
the metal control panel, as this
might result in electrical shock or
damage to the unit.

If your PRO SW-200P needs s er­vicing, contact your local Ra­dioShack store.

• To prevent electrical shock, do not
use this polarized plug with an
extension cord receptacle or other
outlet unless the blades can be
fully inserted to prevent blade
exposure.

• Unplug the PRO SW-200P’s
power cord from the electrical out­let if it will be left unused for a long
time.

• Only connect this uni t to a power
supply of the type des cribed in t he
operating instructions or marked
on the unit.

• Route the power-supply cord so it
is not likely to be walked on or
pinched by items placed upon or
against it, especially a t plugs, con­venience receptacles, and the
point where it exits from the unit.

• Placing the subwoofer on the
same stand or shelf as your turnta­ble can result in low frequency
rumble or acoustic feedback.

Cautions:

• To prevent fire or shock, do not
expose this subwoofer to rain or
moisture.

• Do not place the subwoofer with
its metal plate against the floor.

• Place the subwoofer away from
heat sources such as radiators,
stoves, or other appliances that
produce heat.

CHOOSING A LOCATION

Cautions:

• To prevent the cabinet from warp­ing or discoloring, do not place the
subwoofer in a place where it is
exposed to direct sunlight or
excessive humidit y.

• Do not place the subwoofer where
it might be knocked over or
exposed to falling objects.

Although low frequencies are non-di­rectional, factors such as room ref lec­tions, standing waves, res onance and
absorption strongly affect your sub­woofer’s performance. For maximum
bass output, place your subwoofer in a
corner. To reduce output, move it
away from corners and back walls.
Even slightly moving the subwoofer
can have a major effect on bass re­sponse.

We recommend that you test the sub­woofer in different locations to deter­mine where the best balance is
between your satellite speakers (if
used) and subwoofer. We also recom­mend that you place the PRO SW­200P at least 4 inches away from the
wall, and at least 2–3 feet away from
your television or computer’s disk drive
system so the subwoofer’s magnet will
not distort the colors of your TV picture
or erase your floppy disks.

• The metal control panel on the
back of the PRO SW-200P acts as
the heat sink for the subwoofer’s
internal amplifier. Therefore, place
the unit at least 4 inches (10 cm)
away from a wall, and do not let
anything come into contact with
this panel.

Where and how you position your sub­woofer greatly affects its bass re­sponse. Adjusting the subwoofer’s
volume control in relation to the left
and right speakers and adjusting the
subwoofer’s high cut filter also affects
your speakers’ overall sound.

CARE AND
MAINTENANCE

Your Optimus PRO SW-200P 200­Watt Powered Subwoof er is an exam­ple of superior design and craftsman­ship. The following suggestions will
help you care for your subwoofer so
you can enjoy it for years.

• Keep the subwoofer dry. If it gets
wet, wipe it dry immediately. Liq­uids can contain mi nerals t hat c or­rode electronic circuits.

• Use and store the subw oofer only
in normal temperature environ­ments. Temperature extremes can
shorten the life of electronic
devices, and distort or melt plastic
parts.

• Handle the subwoofer gently and
carefully. Dropping it can damage
circuit boards and cases and can
cause the subwoofer to work
improperly.

To reduce low bass output without af­fecting the mid-bass output equally, ro-

• Keep the subwoofer away from

premature wear of parts.

• Use only fresh batteries of the rec­ommended size and type. Old bat­teries can leak chemicals t hat can
damage your subwoofer’s elec­tronic circuits.

• To maintain the cabinet’s finish, do
not let it come into contact with
water vapor, alcohol, benzene,
insecticide, or similar liquids. Do
not place a plastic covering on top
of the cabinet, as the plastic’s
color could come off and stick to
the finish. Clean the subwoofer
cabinet with a soft, dry cloth.

• Never touch the subwoofer ele­ments with your hands or expose
them to excessive shocks. If the
subwoofer is dented or bent, the
sound is distorted as well.

Modifying or tampering with the sub­woofer’s internal components can
cause a malfunction and invalidate
your subwoofer’s warranty. If your sub­woofer is not performing as it should,
take it to your local RadioShack store
for assistance.
