We Want You Listening For A Lifetime
Used wisely, your new sound equipment will provide a
lifetime of fun and enjoyment. Since hearing damage from loud
noise is often undetectable until it is too late, this manufacturer
and the Electronic Industries Association's Consumer Electronics
Group recommend you avoid prolonged exposure to excessive
noise. This list of sound levels is included for your protection.
Selecting fine audio equipment such as the unit you've just
purchased is only the start of your musk:a] enjoymonr. Now it's
time to consider how you can maximize the fun and excitement
your equipment offers. This manufacturer and the Electronic
Industries Association's Consumer Eleetmnics Group want you
to get the most out of your equipment
by playing it at a safe
level. One that lets the sound come through loud and clear
without annoying blaring or distortiou---and,
most importantly,
without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing "comfort
level" adapts to higher volumes of sound. So what sounds
=normal" can actually be loud and harmful to your hearing.
Guard against this by setting your equipment at a safe level
BEFORE your hearing adapts.

INSTALLATION
When installing the deck, avoid locations with
high temperatures or humidity, and make sure
that the deck receives adequate ventilation.
•

Do not install the deck in locations subject to direct sunlight, or
near a space heater or other heating device, as this may cause
damage to the finish or internal parts.
Malfunctions may also result if the deck is installed in an excessively humid or dusty location. Avoid installing the deck
next to kitchen counters or other locations subject to oily
smoke or humidity.
If the deck is placed directly on top of an amplifier, it may pick
up humming or other noise. Also, if the amplifier generates a
large amount of heat, the deck may malfunction.

•

If the deck is located near a television set, it may pick up interference noise, which will be recorded as a whistling sound on
the tape. If this happens, move the deck further away from the
television set or turn the television set off when operating the
deck.

•

Do not place a cloth over the deck, or block the ventilation slots
in any way. The ventilation slots on this deck are necessary to
keep internal parts cool. If they are blocked, the deck may malfunction.

CONDENSATION
When the deck is moved from a cold location to a warm location,
or when the temperature of the room changes suddenly, condensation may form on the mechanical parts. This can adversely affect the performance of the deck. If condensation forms, wait for
about one hour to allow the deck to adjust to the room temperature. To prevent condensation when heating a room, raise the
temperature slowly.
THE POWER SWITCH IS SECONDARY CONNECTED AND
THEREFORE DOES NOT SEPARATE THE UNIT FROM MAINS
POWER IN STANDBY POSITION.

CLEAN|NG
lAND

CAPSTANS

THE

HEADS"

._.

PINCH

ROLLERS

The heads, pinch rollers and capstans are likely to get dirty quite
easily. If these parts, particularly the heads, get dirty, the high frequency components of a recording will not be reproduced and the
stereo balance will be impaired, resulting in a deterioration of the
playback sound. It is therefore recommended that the head section be cleaned regularly.
1. Set the POWER switch to STANDBY.
2. Press the eject button to open the cassette door.
3. Dip a cleaning swab in cleaning fluid and use it to wipe the
heads, capstans and pinch rollers.
NO TE:
After cleaning the head secdon, do not load a tape until the cleaning fluid has dried completely (about two or three minutes).

I DEMAGNETIZING

THE HEADS

]

After using the cassette deck for a period of time, the heads will
become magnetized. The same effect will occur if a magnetized
screwdriver, magnet or other magnetized object is brought too
close to the heads. When the heads become magnetized, high-frequency sounds will be lost during recording or playback, and interference noise may also occur. The heads should be regularly
demagnetized with a head demagnetizer, which can be purchased
at most audio stores.
When demagnetizing the heads, make sure that the POWER
switch of the cassette deck is set to ON. However, be sure to turn
down the amplifier's volume control to its lowest position, and disconnect any headphones from their headphones jack. For detailed
instructions, refer to the operating instructions of the head demagnetizer.

CLEANING

THE FRONT

PANEL

]

Clean the deck regularly with a soft cloth. If the front panel becomes
soiled, moisten a soft cloth with a weak solution of neutral detergent (diluted in five to six parts water), wring the cloth well, and
wipe the panel clean. Never use volatile cleaners like thinners,
benzine or alcohol because they will damage the panel finish.

Handle the power cord by the plug. Do not pull out the plug by
tugging the cord and never touch the power cord when your
hands are wet as this could cause a short circuit or electric shock.
Do not place the unit, a piece of furniture, etc., on the power cord,
or pinch the cord. Never make a knot in the cord or tie it with other
cords. The power cords should be routed in such a way that they
are not likely to be stepped on. A damaged power cord can cause
fire or give you an electrical shock. Check the power cord regulaw. When you find it damaged, ask your nearest PIONEER authorized service canter or your dealer for a replacement.

done if the "0 dB" indicator lights momentarily at peaks. When

NOTES:
• Theoptimalrecordinglevelmay differ somewhatdependingon

best possible results, set the recordieg level after actualtesting.
Listen to your recordings, and adjust the level as necessary.
The level meter may react differently during recording and

ADJUSTING

THE RECORDING

LEVEL

The adjustment of the recording level is the most important factor
in achieving good recording results. A high level provides a good
signal-to-noise ratio and dynamic range, but an excessively high
level distorts the sound. If the level is set too low for fear of sound
distortion, irritating tape hiss will mar the recording. The characteristics of tapes differ depending on the manufacturer
and the
type of tape. Set the REC LEVEL control so that the level meter's
