If you wish to control your deck with an
external infrared remote control sensor,
connect the wire from the remote sensor to
your cassette deck’s “Remote Input” jack. 
(A control wire may then be run from the
deck’s “Remote Output” jack to the “Remote
Input” of another stereo component.)

Alternatively, if you have a stereo component
with a built-in infrared remote sensor and a
“Remote Output” jack, it may be possible to
connect this jack to the “Remote Input” jack
of your cassette deck. Not all components
are compatible, but it will not hurt to
experiment.

In addition, most Harman Kardon Receivers

include a System Remote Control which will
control the functions of the cassette deck.

Tape heads must be cleaned periodically to
remove tape particles, which gradually build
up on the heads, impairing sound quality and
increasing wear on tapes. Heads may be
cleaned in either of two ways:

1. Slightly dampen a cotton swab in
isopropyl alcohol and gently rub the surfaces
of each tape head. Use a second dampened
swab to clean other surfaces coated with
tape material. Repeat this cleaning every 30
tapes. The TD470 is equipped with an
access hole on the top of the unit to facilitate
cleaning of the heads. Be careful not to lose
the cover to this access hole.

2. Use a tape head cleaning kit, which
comes in the form of a tape cassette, and is
simply inserted into the deck. Follow the
instructions included with the kit.

Tape heads and other internal parts
gradually pick up magnetic fields, which can
add noise to your tapes and even partially
erase them. To prevent this problem, tape
heads should be periodically demagnetized.

A battery-powered demagnetizer is easiest
to use. It comes in the form of a tape
cassette and is simply inserted into the deck.
Be certain to use this demagnetizer as
frequently as its instructions recommend.

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 can
partially erase the tape.

3. To prevent accidental erasure of a tape,
use a small screwdriver to remove the two
square tabs located on the side of the
cassette opposite the exposed tape. With
these tabs removed, the tape cannot be
recorded. If you later wish to record an
erasure-protected tape, simply cover the
small holes with adhesive tape.

4. Do not use old cassettes whose tape no
longer moves smoothly from reel to reel.
They may jam and damage your deck.
