• Never open the cabinet or remove the
metal control panel, as this might
result in electrical shock or damage to
the unit.
• If your PRO-SW220P needs servicing,
contact your local RadioShack store.

a polarized plug with any extension
cord or outlet unless the blades can be

from the electrical outlet if it will not
be used for a long time.

supply of the type described in the

• Route the power-supply cord so it is
not likely to be walked on or pinched
by items placed upon or against it,
especially at the plug, the outlet, and
the point where the cord exits the
unit.
• Placing the subwoofer on the same
stand or shelf as your turntable can
result in a low-frequency rumble or
