Maintenance
Cleaning The Tape Heads
Tape heads should be cleaned periodically
to remove tape particles which gradually
build up on the heads during normal use.
This dirt will impair sound quality and
may cause increased tape head wear. Tape
heads may be cleaned in one of two ways:
1. Use a commercial tape cleaning
cassette. A wide variety of these products is
available from your dealer. Carefully
follow the instructions in the cleaning kit
to avoid damage to your DC520.
2. Remove the cassette from the transport to
be cleaned. Slightly dampen a cotton swab
with isopropyl alcohol or the tape head
cleaning solution available from many
dealers. Gently rub the exposed surfaces of
each head. Use a second moistened swab to
clean other metal surfaces that may be
coated with tape residue such as guide pins.
Be careful to keep the swab away from
rubber rollers unless you are using a
cleaning liquid that is specifically approved
for use on rubber rollers.

Demagnetization
Tape heads and other internal parts will
gradually pick up magnetic fields that may
add noise to your recordings or possibly
cause partial erasure of recorded tapes. To
prevent this problem, tape heads should
periodically be demagnetized using either
of two devices:
1. A battery-powered demagnetizer is
easiest to use. In the shape of a tape
cassette, it simply needs to be inserted into
the transport. Carefully follow the
manufacturer's instructions to insure
proper results.
2. Hand-held, AC-powered demagnetizers
are more effective as they generate stronger
fields. Consult your dealer for information
on this type of unit and be certain to follow
the instructions carefully. When using this
type of unit be certain to keep it away from
prerecorded tapes when it is turned on, as
it may erase them.

Care of Tapes
1. Store cassettes in their cases, in a
location away from direct sunlight,
excessive heat and high humidity.
2. Avoid placing a tape near a television set
or loudspeaker. Their magnetic fields may
partially erase the material on a recorded
tape.
3. To avoid accidental erasure of the
material on a cassette, remove the two
small square tabs located on the top edges
of the cassette. When these tabs are
removed the tape may not be used for
recording. To record on a tape that has
previously had the protection tabs
removed, carefully cover the small holes
with adhesive tape.
4. Do not use old cassettes whose internal
tape reels no longer move smoothly. If you
hear unusual noises during tape motion it
is wise to discard the tape to prevent jams
or damage to your machine.
