Handling cassette tapes
Cautions regarding handling
Do not touch the surface of the tape or pull
the tape out of the cassette.
Tape spooled loosely around the hubs is likely
to jam in the pinch rollers and capstans.
Before loading the tape into the cassette
holder, take up the slack in the tape as shown
below.
Tape storage
Place tapes in their cases for storage.
Avoid storing tapes on top of TVs or
speakers, in sunlight or places of high
temperature, or in humid or dusty areas.
To prevent accidental erasure
Cassette tapes have tabs to prevent
accidental erasure.
If you remove the tabs after making a
recording, the cassette deck cannot be set to
record when that tape is loaded. Remove the
tabs so that valuable recordings will not be
accidentally erased.
Recording (erasure) is not possible when the
tabs are removed.
To make another recording on a tape whose
tabs have been removed, cover the tab holes
with adhesive tape.
Be careful not to cover the tape-type
detection slots.

Maintenance
Cleaning the tape heads
Since the tape is always touching the heads
as it travels through the tape transport, in
time magnetic particles and dust build up,
making the heads dirty. When the heads
become extremely dirty, the sound quality
becomes poor, the output level is reduced,
recording doesn’t work, and previously
recorded sounds cannot be erased (etc.).
In order to prevent important recordings
from coming out as failures, we recommend
cleaning the heads, pinch rollers and
capstans on a regular basis (after about
every 10 hours of use), before the
symptoms described above begin to appear.
Cleaning method
Clean the heads, capstans and pinch rollers
using a wet-type head cleaning tape,
available from an audio store. For more
details, refer to the Instructions of the Head
Cleaning Tape.
Demagnetizing the tape heads
After the cassette deck has been used for
long period of time, the metal parts which
contact the tape may become magnetically
charged. When this occurs, tape hiss
increases, and the high pitched sounds on
recorded tapes will be erased. The same
type of malfunction could also be caused by
bringing a charged metal object (such as a
screwdriver) near the tape heads.
We recommend demagnetizing the tape
heads regularly (after about every 20 to 30
hours of use) with a commercially available
tape head demagnetizer.
You may also use cassette type
demagnetizers with this cassette deck.
When doing so, be sure to turn the volume
of the amplifier all the way down, or you may
harm the amplifier or speakers.
For details, read the instructions that come
with the tape head demagnetizer.
