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.

Setting the time
If a power failure occurs or the AC power cord is disconnected for about 10 minutes, when power is restored,
TOC will be written on the disc.
If the AC power plug is disconnected from the AC outlet
or a power failure occurs during recording (before the
TOC information has been recorded on the disc), the
audio portion being recorded at that time will be erased.
When a recording is being added to a MiniDisc which
already has a recording on it, if the TOC is not updated
before the power failure, the added recording will be
erased.
If a power failure occurs during recording
If this happens, remove the disc, and open the disc
holder. The condensation should evaporate in approximately 1 hour. The unit will then function properly.
When the unit has condensation inside, the disc signals
cannot be read, and the product may not function
properly.
In the following cases, condensation may form inside
the unit.
Shortly after turning on a heater.
When the unit is placed in a room where there is excessive steam or moisture.
When the unit is moved from a cool place to a warm
place.

DISASSEMBLY
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.

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.
• 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.
( ) indicates the record state.
4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.
• Parts marked with “
”(
) are important for
maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and
performance of the set.

TROUBLE SHOOTING
When MD fails operate
If the objective lens of optical pickup is contaminated, MD may fail to operate. At first, clean the objective lens to check playback
operation. If MD fails persistently to operate, perform checks as follows.
If dust or foreign substance is accumulated on the pickup lens, playback is disturbed and indication of TOC (content of tracks) may
be disabled. Before adjusting check that the lens is clean. If the lens is contaminated, treat it as follows.
Turn off power supply, impregnate the lens cleaning paper with a small quantity of isopropyl alcohol, and gently wipe the lens with
it with due care so that the lens is not damaged. At this time do not touch the lens directly with your finger.
