IMPORTANT SERVICE NOTES
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the following
safety checks.
1. Inspect all lead dress to make certain that leads are not pinched or
that hardware is not lodged between the chassis and other metal
parts in the audio product.
2. Inspect all protective devices such as insulating materials, cabinet,
terminal board, adjustment and compartment covers or shields,
mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage current
in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5k ohm, 10 watt resistor paralleled
by a 0.15µF capacitor in series with all exposed metal cabinet parts
and a known earth ground, such as conduit or electrical ground
connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher, sensitivity
to measure the AC voltage drop across the resistor (See diagram).
* Connect the resistor connection to all exposed metal parts having a
return path to the chassis (antenna, metal cabinet, screw heads,
knobs and control shafts, escutcheon, etc.) and measure the AC
voltage drop across the resistor.

All check must be repeated with the AC line cord plug connection

Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp. AC.)
or more is excessive and indicates a potential shock hazard which
must be corrected before returning the audio product to the owner.

Caution on Disassembly
Follow the below-mentioned notes when disassembling
the unit and reassembling it, to keep it safe and ensure
excellent performance:
1. Take the minidisc out of the unit.
2. When disassembling the machine, be sure to withdraw
the power plug from the socket in advance.
3. When disassemble the parts, remove the nylon band or
wire holder as necessary.
To assemble after repair, be sure to arrange the wires as
they were.
If a screw of different length is fitted to the MD mechanism (the screw of the part to be fitted to the MD
mechanism chassis), it may contact the optical pickup,
resulting in malfunction.
4. When repairing, pay due attention to electrostatic charges
of IC.

to the reference DC level.
(Amplitude 0.5 to 1.5 Vp-p) (As the optical pickup has been adjusted before shipping, adjustment is required only when
adjustment disturbance is found.)
*2: Input oscillation frequency 1.5 kHz, 300 mVrms
*3: Make an adjustment so that the error waveform is minimized (Figure 16-3), noise (track jump sound) ceases during audio output
monitoring and clear playback is ensured.
*4: The proper measurement range of oscilloscope is 50 mV, 0.5 ms.
Connect the trigger to the pin 39 (HFD) of IC750, apply coupling on DC (-) slope, and observe waveform in the normal trigger
mode.
*5: Make an adjustment so that the error waveform becomes uniform and is minimized (Figure 16-3), noise (track jump sound)
ceases during audio output monitoring, clear playback is ensured and sound skip and pause state do not occur.
*6: The proper measurement range of oscilloscope is 0.1V, 0.5 ms. The trigger is the same as stated in the note*4 above.
Reference: If the error waveform contains significant noise and is not clear, observe the waveform, using the low-pass filter (Figure

NOTES ON SCHEMATIC DIAGRAM
• Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
• Schematic diagram and Wiring Side of P.W.Board for this
model are subject to change for improvement without prior
notice.

DESCRIPTION
• The indicated voltage in each section is the one measured by
Digital Multimeter between such a section and the chassis
with no signal given.
1. In the tuner section,
( ) indicates AM
< > indicates FM stereo
2. In the main section, a tape is being played back.
3. In the deck section, a tape is being played back.

4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.
