PRECAUTIONS
1. GENERAL
Be sure to use the correct A.C. power source.
Do
not
plug
in
or
unplug
the
power
cord
with
wet
hands.
e@ Handie the power cord with care.
Do
not
remove
the
power
plug
by
pulling
on
the
power
cord.
If
the
insulation
becomes
damaged,
the
conductor
breaks,
or
poor
contacts
occur,
request
service from your authorized service dealer.
@
Do
not
touch
the
inside
of
this
unit
or
remove
the
rear
panel,
@ Disconnect the power cord at the first sign of trouble.
2. LOCATION
@ This unit can become unstable if operated in extremely
high
or
low
temperatures.
Place
it
in
a
well
ventilated
area for correct heat dissipation.
Avoid
placing
in
direct
sunlight,
near
air
conditioners,
poorly
ventilated
areas
or
in
areas
of
excess
humidity
or
dust.
Do
not
block
the
ventilation
holes
in
the
cabinet.
@ Howling sounds (Acoustic Feedback) may occur if this
unit is in direct contact with the speakers.
Be
sure
to
leave
an
appropriate
space
between
the
speakers
and
the
side
of
this
unit.
3. CONNECTIONS
e
Be
sure
to
turn
off
the
power
before
making
connec-
tions.
e
Use
extreme
care
in
making
the
correct
connections.
Reversing
the
R
(right)
or
L
(left)
speaker
leads
or
plus
(+)
and
minus
(—),
will
lead
to
poor
sound
quality.
@ Make all connections securely.
e
Use
speakers
with
a
nominal
impedance
of
8
to
16
ohms.
(When
connecting
one
pair
of
speakers
connected
to
the
A
or
B
terminals).
@
When
using
two
pairs
of
speakers,
ensure
that
the
com-
bined
impedance
(both
pairs
of
speakers
operating)
is
8
ohms
or
above.
The combined impedance is determined using the fol-
lowing formula.
AxB
COMBINED IMPEDANCE = i = (OHMS)
1OWAG: <i a
0. =
g 16+ 16 onms
A: Nominal impedance of speaker A.
B: Nominal impedance of speaker B.
@ Do not supply excessive input to the speakers,
When
using
speakers
with
a
lower
power
handling
capacity
than
the
rated
output
power
of
this
unit
(20 W/ch), avoid excessive volume levels.
4. OPERATION
e
Before
placing
the
power
switch
in
the
ON
or
OFF
posi-
tion,
always
set
the
volume
control
to
the
minimum
level.
@
Do
not
touch
the
turntable
platter
while
it
is
rotating.
@
Do
not
touch
the
tonearm
when
it’s
moving.
5. CARE
@ Do not play badly soiled discs.
e
Be
sure
to
close
the
dust
cover on
the
turntable
when
it
is
not
in
use.

CASSETTE
DECK
MAINTENANCE
(1)
CLEANING
OF
HEADS
—:
Deposit
of
dust
and
dirt
cause
poor
contact
between
the
heads and tape and will lead to:
@ Deteriorating tone quality.
@ Reduced volume.
e@ Failure to record.
e
Erratic
reproduction
of
sounds
(sounds
disappear
mo-
mentarily).
Failure
to
erase
previously
recorded
sounds.
Although the heads should be cleaned at least once in every
10 hours use, to obtain best recording and playback per-
formance, it is recommended to be cleaned every time the
deck is used.
CLEANING MATERIALS
Cotton
Q-tips,
or
a
soft
cloth
such
as
gauze
and
pure
alco-
hol or tape head cleaning fluid.
PROCEDURE
1, Push to open the cassette holder.
2. Remove the cassette cover as shown. (Fig. 1)
3.
Carefully:
wipe
all
tape-contacting
sections
as
the
heads,
pinch
roller
and
capstan.
(Fig.
2)
4.
Re-fit
the
outside
cover
to
its
original
position.
@
Do
not
insert
a
cassette
until
the
alcohol
has
completely
evaporated.
e
Another
cleaning
method
is
to
clean
by
itilizing
a
clean-
ing
tape.
In
this
case,
just
run
the
tape
through
once.
(2)
DEMAGNETIZING
THE
HEADS
The
heads
can
become
magnetized
after
long
periad
of
use.
This
can
cause
excessive
tape
hiss
and
a
foss
of
high
fre-
quencies.
The
heads
should
be
demagnetized
periodically
after
about
30
hours
of
playing
or
recording.
,
1.
Use
a
commercially
available
head-demagnetizer
accord-
ing to its instructions.
Turn off the power switch.
Remove the cassette cover.
Turn
on
the
power
to
the
head-
demagnetizer
and
bring
the
tip
of
the
head-demagnetizer
close
to
the
heads
and
capstan,
and
slowly
move
it
up
and
down
four
or
five
times.
5.
Slowly
remove
the
head-demagnetizer
from
the
heads
to
a
distance
of
more
than
30
cm
(12”)
and
switch
the
power
off.
6. Attach the cassette cover again.
NOTE:
This
unit
requires
no
lubrication.
Lubrication
will
cause
malfunction,
and
may
cause
permanent
damage.

VOLUME POSITION WHEN THE POWER SWITCH IS
TURNED ON OR OFF, OR WHEN CONNECTIONS TO
THE FRONT OR REAR PANELS ARE MADE.
ASSEMBLY AND ADJUSTMENT OF
TURNTABLE
BEFORE ASSEMBLY
1. Remove the fixing screws used for transport.
2. Take off the clamper and binder used for fixing the

and
the
tape
deck
B
in
the
““RE-

Dubbing from another tape deck ({B) to this tape deck (A).
1. Connect the OUTPUT (L and R) terminals of tape deck
(B) to the CD/AUX terminals on the rear panel.
2. Dubbing can be carried out by putting the tape deck (B)
in the play mode and the tape deck (A) in the record
mode, with the FUNCTION selector positioned to CD/
AUX.
* Under the conditions mentioned above, if the tape deck
(B) is in record mode (together with tape deck (A))
oscillation will occur.
ERASING
Performing new recording on a pre-recorded tape auto-
matically erases the previous recording, allowing the new
recording. To erase the previous recording without perform-
ing new recording, proceed as follows:
1. Check that erase protect tabs at the rear of the cassette
tape to be erased are not broken. If broken, cover the
hole(s) with cellophane tape, etc.
2. Press TAPE and then press STOP.
3. Load the tape with the face (A or B) to be erased to-
ward you.
4. Depress the REC button. The tape will now be erased.
5. When the tape comes to the end, the auto stop mechan-
ism will function. If you want to interrupt erasing at
any point, depress the STOP button.
ERASE PROTECTION
Cassettes incorporate a convenient erase-protection device
to prevent accidental erasure. When the tabs at the rear of
the cassette are broken out, the REC button can not be
pushed and the erase protection device will be activated to
prevent accidental erasure of pre-recorded tapes. (Fig, 27)
tf you wish to record on the track on which the tabs have
been already broken out, cover the hole with cellophane or
vinyl adhesive tape. (Fig, 28)
RECORDING PROTECTION FUNCTION—
To protect a recording while it is being made this unit has
no other input facilities apart from the STOP button, REC
PAUSE button, and REC MUTE button. In designing the
unit much thought and care has thus gone into protecting
your recording against loss due to depressing the wrong
function button.
e@ When other functions are to be recorded, be sure to
press the STOP or REC PAUSE button to stop the
recording and switch over to the desired function.
e Synchro recordings can be achieved with MANUAL
button,
UNATTENDED RECORDING AND PLAY—
With the separately sold audio timer (DC-50 type or simi-
lar) you can be woken up by a ‘‘musical alarm’ with the
start of a radio program, a record or tape at whatever time
you like or record radio programs in your absence.

station you wish to hear.
@ When using a record, switch to PHONO and press the
STOP button to allow the tonearm to return to its rest
position on the armrest. If the tonearm is not on the
armrest the record will not start playing when the
POWER is switched ON. So be sure to press the STOP
button to cause the tonearm to return to the armrest
position.
e@ When using a tape as the musical alarm source, switch
unit to TAPE, push the STOP button at the tape position
from which the musical alarm tune is to start.
3. Place TIMER START into the ON position.
4. Adjust the audio timer to the desired time and set the
audio timer switch so that it switches ON when the set
time is reached, (At this time, power ceases to flow to
this unit.)
