aerosol cleaners.
• When the power-supply cord or plug is damaged.
• If liquid has been spilled or objects have fallen into the product.
• If the product has been exposed to rain or water.
Attachments — Do not use attachments/accessories not
recommended by the product manufacturer, as they might create a
hazard.
• If the product does not operate normally by following the operating
instructions. Adjust only those controls that are covered by the
operating instructions, as an improper adjustment of other controls
may result in damage and will often require extensive work by a
qualified technician to restore the product to normal operation.
Water and Moisture — Do not use this product near water (for
example, near a bathtub, washbowl, kitchen sink, or laundry tub; in a
wet basement; or near a swimming pool).
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
accessory.
• If the product has been dropped or damaged in any way.
• When the product exhibits a distinct change in performance.
Replacement Parts — When replacement parts are required, be
sure the service technician uses replacement parts specified by the
manufacturer or having the same characteristics as the original part.
Unauthorized substitutions may result in fire, electric shock, or other
hazards.
Safety Check — Upon completion of service or repairs to this
product, ask the service technician to perform safety checks to
determine that the product is in proper operating condition.
Carts — Move the product on a cart carefully.
Quick stops, excessive force, and uneven surfaces
may cause the product/cart to overturn.
Wall or Ceiling Mount — The product should be mounted to a
wall or ceiling only as recommended by the manufacturer.
Ventilation — Slots and openings in the cabinet provide ventilation,
ensure reliable operation, and protect from overheating. Do not block
or cover these openings, and do not place the product on a bed, sofa,
rug, or other similar surface. Do not place the product in a built-in
installation such as a bookcase or rack unless it provides proper
ventilation as specified by the manufacturer.
Heat — The product should be situated away from heat sources such
as radiators, heat registers, stoves, or other products (including
amplifiers) that produce heat.
Non-use Periods — Unplug the cassette desk’s power cord when
you will not use it for extended periods.
Power Sources — Operate this product using only the power
source indicated on its marking label. 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, contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug. If you need an
extension, use a polarized cord.
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, convenience
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 unattended and unused for long
periods of time, unplug it from the wall outlet and disconnect the
antenna or cable system. This will prevent damage to the product due
to lightning and power-line surges.
Overloading — Do not overload wall outlets, extension cords, or
integral convenience receptacles, as this can result in a risk of fire or
electric shock.

CARE
To enjoy your RCA SCT-550 Dual Cassette Dubbing Deck for a
long time:
• If the tape is wound loosely inside the cassette, use the
tape deck on fast forward or reverse to tighten the tape.
• Keep the cassette deck dry. If it gets wet, wipe it dry
immediately.
• If a small portion of tape is unwound from the cassette,
tighten the tape using a pencil.
• Use and store the cassette deck only in normal
temperature environments.
Use a pencil to
take up the slack
and rotate it in the
arrow direction.
• Handle the cassette deck gently and carefully. Don’t drop
it.
• Keep the cassette deck away from dust and dirt.
• Wipe the cassette deck with a damp cloth occasionally to
keep it looking new.
Erasing Tapes
To record over a cassette tape, simply record as usual. The
cassette deck records over the previous recording.
Modifying or tampering with the cassette deck’s internal
components can cause a malfunction and invalidate its
warranty. If your cassette deck is not performing as it should,
take it to your local RadioShack store for assistance.
You can quickly erase both sides of a cassette tape using a bulk
tape eraser available at your local RadioShack store.
Note: If you use metal tape, the recorded sound might not be
erased properly.
TAPE TIPS
Tape Selection
Preventing Accidental Erasure
For the automatic tape select function to work properly, metal
and chrome (cobalt) tapes must have identification holes.
Cassette tapes have two erase-protection tabs — one for each
side. When a tab is in place, you can record on that side.
To prevent accidental erasure of a tape recording, use a
screwdriver to remove one or both of the cassette tape’s erase-
protection tabs. This prevents REC from being pressed.
Normal Tapes
If you later decide to record on a tape side after you have
removed the erase-protection tab, place a piece of strong
plastic tape over that side’s erase-protection hole. Be sure you
cover only the hole originally covered by the erase-protection
tab.
Chrome (Cobalt) Tapes
Tape Position Identification Holes
Restoring Tape Tension and Sound Quality
Caution: Removing the erase-protection tabs does not prevent
a bulk eraser from erasing a cassette tape.
After you play a cassette tape several times, the tape might
become tightly wound on the reels. This can cause playback
sound quality to deteriorate. To restore the sound quality, fast-
forward the tape from the beginning to the end of one side,
then completely rewind it. Then loosen the tape reels by gently
tapping each side of the cassette’s outer shell on a flat surface.
Environment
Avoid using the deck in the following conditions:
• In areas with high temperatures (near a heater, exposed to
direct sunlight, for example).
Caution: Be careful not to damage the cassette when tapping
it. Do not touch the exposed tape or allow any sharp objects
near the cassette.
• In areas with extremely low temperatures.
• In areas where there is excessive humidity.
• In a dusty atmosphere.
To prevent the tape from being twisted:
• In areas where power line voltage fluctuations are severe
(in which case the use of a voltage regulator may be
advisable).
• Don’t pull the tape out of the upper opening of the cassette
tape.

Cleaning the Tape-Handling Parts
TROUBLESHOOTING
Dirt, dust or particles of the tape's coating can accumulate on
the tape heads and other parts that the tape touches. This can
greatly reduce the performance of the cassette player. After
every 20 hours of tape player operation, follow these steps to
clean the tape-handling parts or use a cassette deck cleaning kit
(available at your local RadioShack store).
This product has been manufactured to the specifications of
RadioShack and is covered by a limited warranty from
RadioShack. If your cassette deck is not operating as it should,
take it to your local RadioShack store or call 1-800-THE-
SHACK for assistance.
