THIS MUSIC SYSTEM IS CAPABLE OF RECEIVING THE NEW AM STEREO BROADCASTS FROM THE AM BAND RADIO STATIONS.
HOWEVER LIKE MANY MUSIC SYSTEM CURRENTLY AVAILABLE ON THE MARKET IT WILL REPRODUCE THIS AM STEREO SIGNAL ONLY
IN AM MONO, WHICH, IN EFFECT, IS OF NO LESSER QUALITY THAN YOUR EXISTING AM MONO MUSIC SYSTEM.
Use a standard AC wall outlet
1. Use from an AC power source of high voltage, such as for
an alr condltioner, is very dangerous.
There is the possibility that a fire might be caused by making
such a connection.
2. A DC power source cannot be used.
Be sure to check the power source carefully, especially on a
ship or other place where DC is used.
supply cord
1. Wet hands are dangerous.
A dangerous electric shock may result if the plug is touched
by wet hands.
2. Never place heavy items on top of the power supply cord,
and never force it to band sharply.
Place the unit where it will be well ventilated
Place this unit at least 10 cm (4”) away from wall surfaces, etc.
Avoid places such as the following:
in direct sunlight or in other places where the temperatura is
high.
in places where there 1s excessive vibration or humidity.
Such conditions might damage the cabinet and/or other compo-
nent parts and thereby shorten the unit's service life,
Be sure to place the unit on a fiat, level sur
face.
If the surface is inclined, a malfunction may result.
| Never attempt to repair or reconstruct this
unit
A serious electric shock might occur if this unit is repaired,
disassembled or reconstructed by unauthorized persons, or if the
internal parts are accidentally touched.
il Grasp the plug when disconnecting the power
Take particular cars if children dre present
Never permit children to put anything, especially metal, inside
this unit. A serious electric shock or malfunction could occur if
articles such as coins, needles, screwdrivers, etc. are inserted
through the ventilation holes, etc. of this unit.
if water is spilled on the unit
Be extremely careful if water is spilled on the unit, because a fire
or serious electric shock might occur. Immediately disconnect
the power cord plug, and consult with your dealer.
0 Avoid spray-type Insecticides
Insecticides might cause cracks or cloudiness” in the cabinet
and plastic parts of this unit. The gas used in such sprays might,
moreover, be ignited suddenly.
. Never use alcohol or paint thinner
These and similar chemicals should never be used, because they
might cause flaking or cloudiness of the cabinet finish.
Disconnect the power supply cord if the unit
will not be used for a long time
If the unit is left for a long time with the power ON, this will not
only shorten its useful operation life, but may also cause other
troubles.
0 If trouble occurs
If, during operation, the sound is interrupted or indicators no
longer illuminate, or if abnormal odor or smoke is detected, im-
mediately disconnect the power cord plug, and contact your
dealer or an Authorized Service Center,
1. insert the dust cover hinges (included) into

To assure good sound quality for recording and playback, be sure
to clean the heads after approximately every 10 hours of use.
1. Press the power switch to switch OFF the power supply.
2. Press the stop/eject button to open the cassette holder.
3. Clean the heads, pinch roller and the capstan shaft of each
deck with a cotton swab (or with a soft, lint-free cloth) slightly
moistened with alcohol.
Do not use any solution other than alcohol for head cleaning.

Heads
Cotton swab \ Pinch roller
| Head demagnetization
In order to maintain good sound quality during recording and
playback, it is recommended that the heads should be
demagnetized if distortion or poor sound quality persist after
cleaning the heads.
If the heads become magnetized, they could create noise in
recordings, loss of high-frequency response, or erasure of
valuable recordings. Several types of head demagnetizers are
available and may be purchased at local electronics supply
stores. Follow the instructions that are supplied with the device.
* Do not bring any type of metal objects or tools such as
magnetic screwdrivers in contact with the head assembly.
Notes about the handling of cassettes
If the tape in the cassette is loose, the tape can easily break dur-
ing use or otherwise be damaged. Never touch the tape itself, or
attempt to pull it out of the cassette.
Use a pencil or similar
object to take up the
slack.
Avoid tape storage in the following
places
Tape can be damaged if it is stored in places such as described
below.
* Where the temperature is high (95° F/35°C or higher) or where
the humidity is high (80% or higher).
* Where there is a strong magnetic field (near a speaker, on top
ofaTY, etc).

Notes
e For automatic presetting in areas where there are fewer than
16 FM stations, the remaining channels (through channel 16)
will be left unoccupied. The unoccupied channels can be filled
by using manual memory presettings.
» For AM broadcasts with extremely strong signal transmissions,
the frequency memorized may be slightly different than the cor-
rect frequency. If this occurs, make a manual presetting.

While listening to FM
broadcasts
An unusual hissing nolse Is
heard when listening to the
broadcast In stereo, but not
heard when listening
monauraily.
Due to the differences between a Monaural and a
stereo signal, a higher level of signal strength is
required for proper stereo reception. If the signal
level is low, a hissing noise may be produced on
the stereo channel.
° Try reducing the treble sound by using the
equalizer controls,

Questions and Answers

What type of tapes should be avoided when using this device?
Avoid using long tapes (20 minutes or longer), Fe-Cr tapes (TYPE IM), and metal tapes, as they can cause sound distortion, instability, and recording issues.
How can I clean the heads, pinch roller, and capstan shaft of the cassette holder?
To clean these components, turn off the power, open the cassette holder, and use a cotton swab or soft, lint-free cloth slightly moistened with alcohol to gently clean the surfaces.
Why is it important to demagnetize the heads?
Demagnetization helps maintain good sound quality during recording and playback by removing any magnetization that can cause noise, loss of high-frequency response, or erasure of recordings.
How can I prevent the tape in a cassette from breaking or becoming damaged?
To avoid tape damage, ensure that the tape is taut within the cassette. If the tape is loose, use a pencil or similar object to take up the slack before using the cassette.
What kind of places should be avoided for tape storage?
Avoid storing tapes in direct sunlight, high temperatures, high humidity, or near strong magnetic fields, as these conditions can damage the tape and recordings.
