CARE
To enjoy your Optimus SCT-540 Dual Cassette Dubbing
Deck for a long time:
• Keep the cassette deck dry. If it gets wet, wipe it dry
immediately.
• Use and store the cassette deck only in normal tem-
perature environments.
• 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 occasion-
ally to keep it looking new.
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 assis-
tance.
TAPE TIPS
Tape Selection
For the automatic tape select function to work properly,
metal and chrome (cobalt) tapes must have identification
holes.
Restoring Tape Tension and Sound Quality
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 loos-
en the tape reels by gently tapping each side of the cas-
sette’s outer shell on a flat surface.
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.
To prevent the tape from being twisted:
• Don’t pull the tape out of the upper opening of the
cassette tape.
• If the tape is wound loosely inside the cassette, use
the tape deck on fast forward or reverse to tighten
the tape.
• If a small portion of tape is unwound from the cas-
sette, tighten the tape using a pencil.
Erasing Tapes
To record over a cassette tape, simply record as usual.
The cassette deck records over the previous recording.
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.
Preventing Accidental Erasure
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.
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.
Caution:
Removing the erase-protection tabs does not
prevent a bulk eraser from erasing a cassette tape.
