1. Disassembly
a.
After
removal
of
batteries,
unfasten
four
set
screws,
two
on
each
side
of
the
case
as
indicated
by
the
crrow
merk
in
Fig.
1.
Then,
pressing
the
record
button
located
on
the
side
(also
arrow-
marked),
push
the
tape
deck
out
of
the
case
in
such
a
wey
tact
the

2.
The
Set
Fails
to
Operate
Completely
(Fig. 2)
The
remote
jack
is
the
smallest
of
the
three
jacks
coming
in
a
row.
o. Defective contact of the remote jack:
The
set
will
not
operate
when
this
jack
fails
to
make
contact
with
each
other
at
the
point
indicated
by
the
arrow
mark
in
Fig.
2.
The symptom typical of this trouble
is that whereas the set operates with
the microphone plug inserted in‘o this
jack and the remote switch turned on,
the set fails to operate when the plug
is pulled off. Check if the lead wire
is broken.
b. Defective contact of push button (Fig. 3):
Such occurs when the segment plates, A and B do not come in
contact with each other even in Play or Rewind position. To remedy
this defect, bend B somewhat in the direction indicated by the arrow
merk in Fig. 3.
c. Defective motor (Fig. 4):
If the reel platform does not revolve in Play or Rewind position
while yet all other parts are found normal, it indicates the defective
motor, which should be replaced.
Use a screwdriver
to unfasten screw.
Fig. 4
d. No operation on battery power supply. Or very slow in re-
volution speed:
The above symptom indicates the worn-out or excessively weak-
ened battery, which must be replaced immediately.

3. The Set Operates but Partially Defective
a. In Play position, it forwards tape but fluctuates in revolution
speed: (Fig. 5)
The above results from the weakened spring pressure of the pressure
spring working the takeup motor, so that the spring should be adjusted
as indicated by the dotted line in Fig. 5.
b.
In
Play
position,
incomplete
rewinding
while
tape
forwarding
is
good:
(Also
see
Fig.
5)
The
coiled
spring
pulling
the
motor
lacks
in
enough
spring
tension.
To
remedy
this
trouble,
cut
the
spring
short
by
1-2t.
Coiled spring pulling motor.

4. Defective Recording and Reproduction while the
Tape Mechanism Normally Functions
a. Defective microphone:
Replace the microphone.
b. Defective contact of jack (Fig. 6):
A normal jack should be such that@' and@)’ are in contact
with each other a plug is not inserted therein. When a plug is inse-
rted,@’ and@)’ become separated, @ and @come in contact with each
other and@)’ and @) separated.
c. Lead wire around jack short-circuited or broken:
If the lead wire short-circuits, remove the cause therefor. If the lead
wire is broken, fix again it by soldering.
