SAFETY INSTRUCTIONS

• 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-SW100P needs ser-
vicing, contact your local Ra-
dioShack 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-SW100P's power
cord from the electrical outlet if it
will be left unused for a long time.
• Only connect this unit to a power
supply of the type described in the
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 at plugs, con-
venience receptacles, and the
point where it exits from the unit.
• Placing the subwoofer on the
same stand or shelf as your turnta-
ble 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.
