IMPORTANT SAFEGUARDS
Please read ail of the safety and operating instructions
before operating this unit. For best results, follow all
warnings placed on the unit and adhere to the operat-
ing and use instructions. These safety and operating in-
structions should be retained for future reference.
1. Power sources — The unit should be connected
to a power supply only of the type described in the
operating instructions or as marked on the appliance.
2. Power-cord protection — Power-supply cords
should be routed so that they are not likely to be
walked on or pinched by items placed upon or
against them, pay particular attention to cords at
plugs, convenience receptacles, and the point where
they exit from the unit.
Never pull or stretch
the cord.
3. Grounding or polarization — The precautions
should be taken so that the grounding or polariza-
tion means of this unit is not defeated.
4. Ventilation — The unit should be situated so that
its location or position does not interfere with its
proper ventilation.
To maintain good ventilation, do not put records or
a table-cloth on the unit. Place the unit at least
10 cm away from the wails.
Do not use the unit on a bed, sofa, rug or similar
surface that may block the ventilation openings.
5. Water and moisture — The unit should not be
used near water — for example, near a bathtub,
washbowl, kitchen sink, laundry tub, in a wet base-
ment, or near a swimming pool, etc.
6. Temperature — The unit may not function pro-
perly if used at extremely low, or freezing tempera-
tures. The ideal ambient temperature is above +5°C
(41°F).

safe operation.
Heat — The unit should be situated away from
heat sources such as radiators, heat registers,
stoves, or other units (including amplifiers) that
produce heat.
. Electric shock — Care should be taken so that ob-
jects do not fall and liquid is not spilled into the en-
closure through openings. If a metal object, such as
a hair pin or a needle, comes into contact with the
inside of this unit, a dangerous electric shock may
result. For families with children, never permit chil-
dren to put anything, especially metal, inside this
unit.
Enclosure removal — Never remove the en-
closure. If the internal parts are touched accidentally,
a serious electric shock might occur.
Magnetic fields — Keep the unit away from
sources of magnetic fields such as TV sets, speaker
systems, radios, motorized toys or magnetized
objects.
. Cleaning — Do not use volatile solvents such as
alcohol, paint thinner, gasoline, or benzine, etc. to
Clean the cabinet. Use a clean dry cloth.

ACaution : Read this page carefully to ensure safe
12. Carts and stands — An appliance and cart com-
bination should be moved with care. Quick stops,
excessive force, and uneven surfaces may cause
the appliance and cart combination to overturn.
——
13. Nonuse periods — The power cord of the unit
should be unplugged from the outlet when left un-
used for a long period of time.
14. Abnormal smell — !f an abnormal smell or smoke
is detected, immediately turn the power OFF and pull

the unit; or
C. The unit has been exposed to rain; or
D. The unit does not appear to operate normally or
exhibits a marked change in performance; or
E. The unit has been dropped, or the enclosure
damaged.
16. Servicing — The user should not attempt to ser-
vice the unit beyond that described in the operating
instructions. All other servicing should be referred
to qualified service pérsonnel.
17. Outdoor antenna grounding — If an outside an-
tenna is connected to the receiver, be sure the an-
tenna system is grounded so as to provide some
protection against voltage surges and built up stat-
ic charges. Section 810 of the National Electrical
Code, ANSI/NFPA 70, provides information with
respect to proper grounding of the mast and sup-
porting structure, grounding of the lead-in wire to
an antenna discharge unit, size of grounding con-

Before operation
Notes on cassette tape
Safety tab (accidental erasure prevention tab)
After an important recording has been finished, break the safety
tab, to prevent the recorded contents from being erased or re-
corded on accidentally.
To re-record Cover with adhesive tape.
Notes:
To store cassette tapes
Do not store the tapes in a place which is subject to direct sun-
light, or near equipment that generates heat. Keep the cassette
tapes away from any magnetic field.
When there is slack in the tape
In such a case, insert a pencil into the reel hole and wind the
reel hub to remove the siack.
1. 120-minute cassette tape
Since a 120-minute cassette tape is very thin, the tape could
adhere to the pinch roller or be easily cut. It is recommended
that these tapes not be used with this unit to prevent possible
damage.
Cleaning the head section
2. Endless tapes
Do not use an endless tape, as this could damage the mecha-
nism of the unit.

ponents
For maintaining the best condition of the deck
and for longer service life, always keep the

Demagnetizing the head
When the recording / playback head is magne-
tized, the sound quality will be deteriorated. In
such a case, demagnetize the head using a
commercially available demagnetizer (head
eraser).

1. Press the OPEN/CLOSE key to open the
EE cassette holder.
2. Using a cotton swab dipped in alcohol, clean

Note:
There are precisely aligned parts around the
heads, including the tape guides.
When cleaning, pay special attention so as not to
apply shock to them.
Beware of condensation
When water vapor comes into contact with the surface of cold
material, water drops are produced.
If condensation occurs, correct operation may not be possible,
or the unit may not function correctly.
This is not a malfunction, however, and the unit should be dried.
(To do this, turn the POWER switch ON and leave the unit as it
is for several hours.)
Be especially careful in the following conditions:
e@ When the unit is brought from a cold place to a warm place,
and there is a large temperature difference.
@ When a heater starts operating.
e@ When the unit is brought from an air-conditioned place to a
place of high temperature with high humidity.
e@ When there is a large difference between the internal tem-
perature of the unit and the ambient temperature, or in condi-
tions where condensation occurs easily.
