To  obtain  the 
very 
best  performance  from  your  deck, 
we 
urge  you  to  read  this manual thoroughly before attempting 
operation.  Please  keep  this  manual  handy  for  further 
reference.

be 
kept clean  and  demagnetized  at all  times. 
*   Before 
using 
a cassette tape, check  to 
con 
firm 
whether tape 
slack  exists. 
As 
tape 
slack 
causes the tape  twist  or  tangle 
around  the  pinch  wheel  and  capstan,  take 
up 
slack  if 
necessary.

*  
As 
the  base 
of 
C-120  tapes  are  thin  and  easily  damaged, 
they are not recommended for 
use 
with this maehine. 
'"  
Recording  cannot 
be 
made  on  the  leader  tape.  Therefore, 
when  using  a 
new 
cassette tape, 
be 
sure to forward  the tape 
slightly 
so 
that the leader tape 
is 
not 
in 
the head  path. 
'"  
Tapes  which 
have 
been  stored 
in 
a  hot  moist 
place 
for  a 
period 
of 
time 
or 
cassette tape  with  bent 
cases 
should  not 
be 
used.  Such  tapes may  curl or 
have 
greasy  places altering 
tape  speed 
and 
preventing  proper  performance.  Always 
store tapes 
in 
a cool, dry  place. 
'"  
Do 
not touch  the  tape  with  your  fingers 
as 
high 
frequency 
signals 
cannot 
be 
recorded 
in 
places which are not 
clean 
on 
the tape. 
*  
When 
using 
a tape recorded  with  the  Dolby  processor, it 
is 
necessary  to depress the Dolby 
NR 
Switch at playback  time 
also. 
Keep  the  Dolby 
NR 
Switch  at  OFF  position  at all 
times 
except during Dolby recording or playback. 
*   Cassette  tapes  are equipped with a break-out tab for  both A 
and 
B sides. 
When 
these tabs 
have 
been 
removed to protect 
an 
important  recording, 
no 
further  recording 
can 
be 
made 
on 
the tape unless the cavities are  plugged or covered  with a

..-
This 
model 
employs 
a 
4-track 
recording/playback 
system. 
The 
first 
half 
of 
the 
stereophonic 
recording 
or 
playback 
takes 
place 
on 
track 
1 and 
2. 
The 
second 
half 
takes 
palce 
on 
tracks 
3 
and 
4 
after 
the 
cassette 
has 
been 
inverted, 
Recording 
and 
playback 
time 
depend 
upon 
the 
length 
of 
the 
tape 
(C-30, 
30 
minutes; 
C-60, 
60 
minutes, 
etc.). 
Monaural 
and 
stereo 
recorded 
tapes 
can 
be 
played 
back 
on 
either 
stereo 
or 
monaural 
cassette 
recorders 
without 
any 
loss  in 
quality. 
Because 
the 
total 
track 
width 
of 
the 
left 
and 
right 
channels 
is 
equal 
to 
that 
of 
the 
monaural 
track, 
the 
playback 
head 
will 
scan 
both 
left 
and 
right 
channels 
together. 
This 
results 
in 
automatic 
mixing 
of 
left 
and 
right 
channels 
from 
the 
stereo 
tape 
for 
monaural 
reproduction.
