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 protect a recording from being accidentally recorded over or erased,
use a screwdriver to remove one or both of the cassette tape's
erase-protection tabs.  This prevents RECORD 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.

Recording Over or Erasing a Cassette Tape

To record over a cassette tape, simply record as usual.
The cassette player records over the previous recording.

You can quickly erase both sides of a cassette tape using a bulk tape
eraser (Cat. No. 44-232).

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 loosen the tape
reels by gently tapping each side of the cassette'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.

Cleaning the Tape-Handling Parts

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
cassette player's performance.

To prevent noise and poor High-frequency response, follow these steps to
clean the cassette player's tape-handling parts after every 20 hours of
use.  Your local Radio Shack store sells a complete line of cassette deck
cleaning supplies.

1.  Set FUNCTION to TAPE.

2.  Remove the batteries and disconnect any other power source.

3.  Open the cassette compartment door.

4.  Press and hold down the erase-protection tab sensor, then press RECORD
    to expose the record/playback and erase heads.

5.  Use a cotton swab dipped in tape head cleaning solution or denatured
    alcohol to gently clean the capstans, pinch rollers, tape guides, and
    tape heads.

6.  Press STOP/EJECT and close the cassette compartment door, then
    reinstall the batteries or reconnect the power source.
