WARNINGS (MD)

The AEL (ACCESSIBLE EMISSION LEVEL) of the laser power
output is less than class 1 but the laser component is capable
of emitting radiation exceeding the limit for class 1. Therefore it is
important that the following precautions are observer during
servicing to protect your eyes against exposure to the laser beam.

1) When the unit case cover is removed and LOADING SW (SW

1956) is turned on and then PLAY SW (SW 1954 mechanism
PWB) is turned on in a few second.

The laser will light for several second to detect a disk.

2) The laser power output of the pickup unit and replacement service
parts are all factory pre-set before shipment.

Do not attempt to re-adjust the laser pickup unit during replacement

or servicing.

IMPORTANT SERVICE NOTES (For U.S.A.Only)

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.

MD-MX30/MX30W

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

VOLTAGE SELECTION(For MD-MX30W)

The voltage selector is located on the AC voltage selector box. If adjustment is necessary, ensure to remove plug of AC cord from
AC socket and use a screwdriver in order to turn the selector in either direction. The correct voltage figure is displayed in the window
below to the adjustment screw.

DISASSEMBLY

Caution on Disassembly

The disassembling the machine or assembling it after
repair, observe the following instructions to ensure safety
and keep its performance.

1. Unload the compact disc, and mini-disc, cassette tape
from machine.

2. Be sure to unplug the power cable before starting
disassembly of the machine.

3. When disassembling each section, remove the nylon
band or wire arrangement.
After servicing the unit, be sure to rearrange the leads
where they were before disassembling.

If a screw of improper length is fit to the MD mechanism.

(A screw fit the part to the mechanism chassis of MD
section), it may contact the optical pickup, impeding
normal operation. Hence, due care must be taken.

4. While repairing, pay utmost attention to static electricity
on ICs.

Notes for servicing (For MD-MX30 only)

• This model is equipped with a fan. If you remove the fan to
service the unit, it enters the protection mode and the
power cannot be turned on by pressing the POWER
button. In such a case, follow the procedure below.
(Refer to Fig.10-1.)

1. Check whether a resistor (RV 66,39ohm,1/2W) is inserted.If

not, connect it (39ohm,1/2W).

2. Connect the patterns circled with a dotted line by soldering.

• Desolder to reassemble the unit after repairing. If you fail

to desolder, the power turns off soon because the unit
enters the protection mode when the fan rotates at a high
speed (high power).

• These steps are unnecessary to service the unit with the

fan connected.

• Adjustment

Since this CD system incorporates the automatic adjustment functions, readjustment is not needed when replacing the pickup.
Therefore, PWBs and pickups can be combined freely.
Each time a disc is changed, automatic adjustment is performed. Therefore, playback of each disc can be performed under
optimum conditions.

EEPROM WRITING PROCEDURE

EEPROM (IC1402) writing procedure

1. Method for setting the reference temperature value

(This setting should be performed quickly at a room
temperature, between 21°C and 29°C when the PWB is not
hot.)

(1) When replacing the EEPROM, wait until it has cooled down.
(2) Connect the main unit using the single MD main PWB.
(3) Enter the test mode as shown on page 22.

"EJECT"

(4) Press the NORMAL button.

"TEMP "

:Measured temperature, : Temperature setting

(5) Find the temperature correction value for the current ambient

temperature on the following table. Adjust the temperature
correction value using the VOLUME knob.

Ambient temperature correction

+ 21.0 °C ~ + 23.2 °C -1 H
+ 23.3 °C ~ + 26.8 °C ± 0 H
+ 26.9 °C ~ + 29.0 °C +1 H

An example: When ambient temperature is 22°C and measured

temperature is 7AH
Temperature setting = 7A H - 01 H

= 79 H
* When the measured temperature fluctuates between
two values, take lower one (if temperature fluctuates
between 7AH and 79H, take 79H).

(6) Press the MEMORY/ENTER button and write the temperature

setting into the EEPROM.

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.

MD-MX30/MX30W

• 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.
