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.
