1. Critical Components Information.
Components having special characteristics are marked Z
and must be replaced with parts having specifications equal
to those originally installed.

2. Leakage Current Measurement (For 120V Models Only).
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.

● Meter impedance should be equivalent to 1500 ohm shunted

by 0.15µF.

● Leakage current must not exceed 0.5mA.

● Be sure to test for leakage with the AC plug in both

polarities.

CAUTION: USE OF CONTROLS OR ADJUSTMENTS

OR PERFORMANCE OF PROCEDURES
OTHER THAN THOSE SPECIFIED
HEREIN MAY RESULT IN HAZARDOUS
RADIATION EXPOSURE.

WARNING: CHEMICAL CONTENT NOTICE!

The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or
plastic (where applicable) components may also contain traces of chemicals found by the California Health and
Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR
ANY REASON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes
or expose eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands
before handling food.

aluminum foil or the like which is
electrically conductive so as to prevent
the optical pickup from being
damaged by static electricity.

Caution

Almost the entire surface of the cartridge holder is

coated with oil. When removing the mechanism, hold it

at the rear end (where marked with arrows in the figure)

and avoid touching the oiled surface.

Installation of Cartridge Holder

• To install the cartridge holder, the rack of the mechanism must be

lowered toward the rear.

• While pushing the roller arm lever outward, push in the slider lever.

• Apply a +5V voltage to the loading motor (until clicking sound is

heard) and push in the rack gear.

• With the slider lever and the rack gear installed as described above,

fit the cartridge holder as shown in the figure and tighten screws.

be necessary to perform “Adjustment of Lead-in Switch
Position”. (See page 13.)

1. Remove 2 screws (E1) and then remove the Mecha­nism SW P.C.B.

Installation of Mechanism SW P.C.B.

• Set the mechanism to the eject mode by applying -5V

to the loading motor.

• Install the mechanism SW P.C.B. so that the boss fits

in the hole in it.

• Push the lead switch on the mechanism SW P.C.B.

toward the optical pickup side (so that looseness in the
boss hole is eliminated).

• Tighten screws and apply thread lock.

• Measure the lead-in switch position. (See page 13.)

1. Remove 3 screws (C1).

2. Remove the spindle motor by moving it in the arrow
direction.

Caution

a. Be careful not to scratch the gear.

(Scratched gear will produce noises during searching.)

b. As the turn-table is magnetized, keep foreign objects

from being attracted.

(The damaged gear will cause abnormal noise to occur

while searching.)

2. Remove a screw (F2).

The leaf spring (A) attached to the P.U. will be reused
when replacing the pickup. It is not supplied with the
optical pickup.

3. Using tweezers or the like, pull the PU shaft from the

base a little. Pull only enough to allow the pickup to
come off. If it is pulled off completely, the oil on the
shaft will be scraped off.

Be sure to keep oil on the shaft!

sure to tighten the leaf spring (A) with it.

• When installing the pickup to the MD mechanism, fit

the pickup into the MD guide (B) first, match the boss
of the MD guide (A) and its hole in the chassis and
tighten them with a screw.

2. How to set to each mode

Every time the DISPLAY button is pressed, the mode changes. (For operation of each mode, refer to the section
describing each mode.)

->AUTO pre-adjustment -> AUTO adjustment -> RESULT preparation -> RESULT -> MANUAL pre-adjustment ->
MANUAL adjustment -> EEPROM setting

Caution) The AUTO pre-adjustment and AUTO adjustment modes are used for adjustment during servicing. Other modes

are used when checking the specific measured values and adjusted values or when changing the set value and the
adjusted value. Note that use of other modes will rewrite RAM and EEPROM.

3. How to cancel test mode

1) Finish the AUTO pre-adjustment and AUTO adjustment. ( “COMPLETE” appears on the display)

2) Press the REC button. ( “TEST END” appears on the display)

3) Eject the disc by pressing the EJECT button.

4) Turn off the power.

● When using a new combination of a mechanical pickup and an MD P.C.B. after a repair or for some other

reason, make sure to set to the TEST mode and perform AUTO pre-adjustment and AUTO adjustment accord­ing to the following procedure.

1) Set to the TEST mode and perform AUTO pre-adjustment and AUTO adjustment.

2) Cancel the TEST mode by pressing the REC button. (Writing into EEPROM starts from here.)

3) Eject the disc by pressing the EJECT button.

4) Turn off the power.

● Confirmation of pick-up laser power

Recording and reproduction can be checked by using the laser power meter. However it should be used for checking only
because there is variation in its measurement.
When the measured value is excessively deviated from the reference value, replace the pick-up.

Reference value (measured at room temperature of 25 °C)
During reproduction (ppw) : 0.72 ± 0.1 mW
During recording : 5.5 ± 0.5 mW

Note : Be very careful when using the laser power meter. The laser beam would cause damage to your eye if exposed to it

directly.

● Forced rotation of loading motor

It is possible to force the loading motor to rotate by turning the jog dial when the microprocessor version (tsm13**e**)
of the test mode or EJECT appears on display. (This is used when the disc cannot be ejected.)

* To obtain the microprocessor version on display When a disc is loaded, “ _ AUT _ YOBI _ ” appears on display. Press

the DELETE/CANCEL key in this state, and the microprocessor version will appear.

● Confirmation of magnetic head installation position

• After replacing the magnetic head and the optical pick-up, be

sure to confirm their installation positions.

• To facilitate adjustment of their installation positions, bring the

optical pick-up to the center position and follow the procedure
described below.

● How to set to the special test mode

Press the POWER button while pressing the SET/ENTER button and the STOP button. Then all the indicators will light up.

● Operation procedure

Every time the SET/ENTER button is pressed, lighting of indicators and items on the display change as follows.

1) All indicators light up.

2) All indicators turn off.

3) Segments not sharing the border light up.

4) Above segments turn off and other segments light up.

5) The date when the software was entered appears on the display.

6) The version of the micro processor appears on the display. [ CPU Ver:TP01 ]

7) The time of auto-marking appears on the display. [ AM Time :C8h ]

8) The analog level of auto-marking appears on the display. [ AM Lv1_A:24h ]

9) The digital level of auto-marking appears on the display. [ AM Lv1_D:1Ah ]

10) Write/read check for EEPROM appears on the display [ EE W/R Check ]
When the INPUT button is pressed at this point, whether the micro processor executed data write/read function into
EEPROM or not is checked.
If [OK] appears on the display and the pin 6 of IC6 is at “H”, the check result is satisfactory.
[NG] is displayed when there is an error while writing or reading the data.
In such a case, check EEPROM (IC7).

● How to cancel the special mode

Press the STOP button, and the mode will change from the special test mode to the product mode and the data in RAM will
be cleared.
Note : Turning off the power will cancel the special test mode but will not clear the data in RAM.

■ TROUBLESHOOTING

When MD fails to operate

When the objective lens of the optical pickup becomes dirty, MD may fail to operate. Clean the objective lens first and
check MD for reproduction function. If it still fails to operate, check according to the following flow charts.
Contaminant on the pickup lens such as dust and a foreign matter may cause the pickup to skip or the TOC (content of the
selection) not to be displayed. Check if the lens is clean before making adjustments. If the lens is dirty, clean it as follows.

● Turn off the power. Dampen the lens cleaning paper with a small amount of isopropyl alcohol and wipe the lens with it,
using care not to cause any damage to the lens. Be sure not to touch the lens with your hand directly.
