Important Safety Instructions
The SCT-56 is made and tested to meet exacting safety
standards. It meets both UL and FCC requirements
Careful attention is devoted to quality standards in the manufacture of your cassette deck, and safe-
ty is a major factor in its design. However, safety is also your responsibility.
This section lists important information that will help you properly use and enjoy your cassette deck
and accessories. Read all the included safety and operating instructions before using your cassette
deck. Follow them closely, and retain them for future reference.
To prevent fire or shock hazard, do not expose this sys-
tem to rain or moisture.

ABLE PARTS INSIDE. REFER SERVICING
TO QUALIFIED PERSONNEL.
Accessories — Do not place this product on an unstable cart, stand, tripod, bracket, or table. The
product 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 the manufacturer or sold with the
product. Follow the manufacturer's instructions for mounting, and use a recommended mounting ac-
cessory.
Carts — Move the product on a cart carefully. Quick stops, excessive force, and
uneven surfaces may cause the product/cart to overturn.
Ventilation — Slots and openings in the cabinet provide ventilation, ensure reli-
able operation, and protect from overheating. Do not block or cover these open-
ings, and do not place the product on a bed, sofa, rug, or other similar surface. Do

within the system’s enclosure that might be of
sufficient magnitude to constitute a risk of
electric shock. Do not open the system’s

If you are not sure of your home's power type, consult your product dealer or local power company.
Polarization — This product is equipped with a polarized AC line plug (a plug having one blade
wider than the other). This plug will fit in the power outlet only one way. This is a safety feature. If
you cannot insert the plug fully into the outlet, try reversing the plug. If the plug still doesn't fit, con-
tact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polar-
ized plug. If you need an extension, use a polarized cord.

portant operating and maintenance instruc-
tions are included in the literature
accompanying this system.

Power-Cord Protection — Route power-supply cords so they are not likely to be walked on or
pinched by items placed on or against them, paying particular attention to cords at plugs, conve-
nience receptacles, and the point where they exit from the product.
Lightning — For added protection for this product during a lightning storm, or when it is left unat-
tended and unused for long periods of time, unplug it from the wall outlet and disconnect the anten-
na or cable system. This will prevent damage to the product due to lightning and power-line surges.
