SERVICING NOTES
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK !OR DOTTED
LINE WITH MARK !ON THE SCHEMATIC DIAGRAMS
AND IN THE PARTS LIST ARE CRITICAL TO SAFE
OPERATION. REPLACE THESE COMPONENTS WITH
SONY PARTS WHOSE PART NUMBERS APPEAR AS
SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-
LISHED BY SONY.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
This MiniDisc player is classified as a CLASS 1
LASER product.

General
• In the TEST mode, this set provides the Auto mode in which
both CD and MO are adjusted automatically. In theAuto mode,
whether a disc is CD or MO is discriminated, then each
adjsutment is automatically executed sequentially. If a fault is
found, it is displayed.Also, in the Servo mode, each item can be
adjusted automatically.
EnteringTEST Mode
Bridge theTAP801 (TEST) on MAIN board (connect IC801 #™ to
GND), and turn the power on.
Then, press (key and the TEST mode is activated.
ReleasingTEST Mode
Turn the power off, and remove the bridge from TAP801 (TEST)
on MAIN board.
Operation inTEST Mode
In the TEST mode, the LCD display is as shown below:
• ROM version display → All ON → All OFF are repeated.
• To hold the display for confirmation, press the PLAY MODE
key.

AUDIO Mode
• Enter the TEST mode, and press VOL −key, (key, and VOL
+ key in this order to select the AUDIO mode.
• To select other modes, refer to the TEST mode configuration.
1. Configuration of AUDIO Mode
• The mode No.111 is for S/N and cross talk, and 115 for distor-
tion factor and frequency characteristic.
• When VOL + / −key is pressed in any mode, the headphone
volume changes every step.
Also,When +or =key is pressed, the headphone volume
becomes maximum or minimum.
• Once the volume level was changed, fundamentally it contin-
ues, but it returns to default value when the mode is changed
from 114 to 115, or 118 to 119.

Precautions on Adjustment
• In this set, the CD and MO adjsutment can be executed auto-
matically by selecting the TEST mode.
• Execute adjustment in the AUTO mode, then if NG occurred,
readjust faulty item in the SERVO mode.
Adjustment in AUTO Mode
1. Enter the TEST mode, and pressVOL + key to select theAUTO
mode.
2. Insert the CD Test disc (TDYS-1) or commercially available
SONY MO disc (already recorded).
3. Press (key twice, and the CD or MO is discriminated, then
respective items are automatically adjusted in the order as listed
in tables below.

4. If automatic adjustment result is OK, the display is as follows:
5. If automatic adjustment result is NG, the display is as follows:
* In case of NG, select the SERVO mode, and readjust NG item
automatically.
Adjustment in SERVO Mode
1. Select each adjusting mode following the configuration of
SERVO mode, and the lower 2 digits of mode number and the
adjusted value written to the EEPROM are displayed on the
LCD.
2. Press Pkey, and the display changes as shown below and
automatic adjustment is executed.
Note: Though the adjusted value can be changed to any value with VOL
+ or −key, avoid frequent change.
3. Whem automatic adjustment is finished, the adjusted value
changes from blinking to lighting.

ELECTRICAL PARTS LIST
Ref. No. Part No. Description Remark
NOTE:
• Due to standardization, replacements in the
parts list may be different from the parts speci-
fied in the diagrams or the components used
on the set.
• -XX and -X mean standardized parts, so they
may have some difference from the original
one.
• RESISTORS
All resistors are in ohms.
METAL: Metal-film resistor.
METAL OXIDE: Metal oxide-film resistor.
F: nonflammable
• Abbreviation
FR : French
HK : Hong Kong
• Items marked “*” are not stocked since they
are seldom required for routine service.
Some delay should be anticipated when order-
ing these items.
• SEMICONDUCTORS
In each case, u: µ, for example:
uA. . : µA. . uPA. . : µPA. .
uPB. . : µPB. . uPC. . : µPC. .
uPD. . : µPD. .
• CAPACITORS
uF: µF
• COILS
