1. SHOCK, FIRE HAZARD SERVICE TEST:
CAUTION: After servicing this appliance and prior to
returning to customer, measure the resistance between
either primary AC cord connector pins (with unit NOT
connected to AC mains and its Power switch ON), and
the face or front Panel of product and controls and chassis
bottom. .
Any resistance measurement less than 1. Megohms should
cause unit to be reparied or corrected before AC power
is applied, and verified before return to user/customer.
Ref. UL Standard NO. 1270. Para 66. 3. D (Mandatory
Test after servicing Electrical Appliances, effective 7- 1-83).
2. P.W. BOARDS

4. MECHANISM AND CIRCUIT DESCRIPTION
4.1. Muting System
The muting circuit is provided to reduce the pops noise when
generates on the Line Out at power ON/OFF.
1) When power is turned on.....
As the emitter voltage of QLO5 is higher than the base voltage
during the charge current flows to CL10 through RL15 & RL16,
QLO5 is ON and it sends the muting voltage.
CL10 has been charged up, both the base and the emitter voltages
of QLO5 are equal. QLOS5 is OFF and the muting is released.
When the STOP button is depressed .....
When the stop switch $073-1 is ON, the base current flows
through. Also discharging CL10, QLO5 is ON instantly, the muting
system operates to reduce the pops noise at power ON/OFF.
QM06 provides to discharge CL10 on AUTO STOP.
As the muting time is in proportional to capacitance of CL10,
it is preset by matching the threshold time of TAPE EQ Amp.
DLOS5 provides to discharge CL10 on FF and REW.

4.2 Auto Play and Automatic Rewind Stop
(PMD221 only)
With $S01 set to ON during PLAY, the rewind button will lock when
pressed. When counter reaches 999, the rewind lock releases and
the PLAY operation resumes. In this condition, both CUE and
REVIEW buttons do not operate and both buttons are locked. Also,
when the FF button is pressed and locked in place, the lock releases
when the counter reaches “900” and the PLAY mode is entered.
When the tape has finished winding in both modes before the
counter reaches the respective positions, the AUTO STOP function
and all buttons are released. Also when the REWIND button alone
is locked, the tape rewinds and rewind stops when the counter
reaches “999”. The same applies for fast foward operation which
stops at “900”. When the counter is between “900” and “999”,
both REWIND and FF buttons do not lock.
4.3 Auto Stop
The AUTO STOP function which detects the end of the tape is car-
ried,
out
by
hole
IC
(QM07).
The
signal
from
QMO07
is
added
to
the
pin @of QMO8, while the auto stop duration is designated inside
QM0O8.
The
time
it
takes
for
the
auto
stop
function
to
activate
after
the tape stops, is determined in. CMO8. At this time TE is
TE =75xCMO8 (uF)mSec, while TW is TW = 30 x CMO7
(uF
)mSec
as
long
as
the
auto
stop
function
is
operating.
When
it
does not shut off the first time, TE--TW--TE--TW is repeated until it
shuts off.

4.4 Pitch Control
The pitch control is used to vary the tape speed for playback opera-
tion. During recording, it is automatically set to the RM14 center
position by SJO1.

4.6 Low Battery Indicator
This circuit illuminates the LED when the supply voltage level is
attenuated.
The dividing ratio for RY30 and RY31 determines the voltage at
which the light is illuminated.

about 0.6V.

5. ELECTRICAL ADJUSTMENTS
Precautions for Adjustment and: Measurement
1. Before playing back the test tape, thoroughly demagnetize the
heads, capstan and similar metal parts using an erase, as the
test tape-recorded tone is easily erased.
2. Do not place the test tape on any measuring instrument.
3. Do not put the test tape near a place where the eraser is used.
4. Method of Demagnetization: Turn the eraser power switch on
at a position far away from the heads. Bring the eraser close to
the heads, capstan and other parts to be demagnetized, and
move it up and down four or five times to demagnetize. Slowly
separate the eraser far away from the parts,’ and turn the power
switch off. d
5. Do not use any. magnetized adjusting tool. If necessary,
demagnetize with a bulk eraser from time to time ‘in the course
of each adjustment.
6. Do not turn semi-fixed resistor or coil more than needed.
7. Measure speed and wow and flutter in the normal operating state.
8. Do,not apply logggibg-bond excessively.
5.1 Head Azimuth Adjustment
1. Play the test tape MTT256 back. Adjust the head azimuth ad-
justing screw for maximum VTVM reading.
2. After adjustment, repeat the playback and stop settings several
times to confirm no azimuth deviation.
3.. After adjustment, lock the screws with bond.

2. Adjust the adjusting resistor (RMO4) on the PMOO PW. Board
so that counter readings are between 2990 — 3010Hz.
3. Then, adjust the Speed Selector Switch to LOW PLAY, and play
MTT-111 back.
