Operation to reset
The microcomputer may fall into malfunction (impossibil-
ity to operate, erroneous display, etc.) when the power
cord is unplugged while unit is ON or due to an external
factor. In this case, execute the following procedure to
reset the microcomputer and return it to normal condi-
tion.
Unplug the power cord from the power outlet then,
while holding the set/demo key depressed, plug
the power cord again.
Please note that resetting the microcomputer clears
the contents stored in and it returns to condition when
it left the factory.

1. Initialization
1-1 Setting of the Initial Conditions
While pressing the (STOP) key, plug the AC cord to AC
wall outlet.
1-2 Initializing Operation
A microcomputer is initialized for start when the AC
power is turned on while pressing the [STOP] key.
At that time, CD,MD and CASSETTE mechanisms are
also initialized.
During the initial conditions, the display shows "INI-
TIALIZE" and after that it will be returned to standby
conditions.
1-3 Initial Items
1-4-3 MD mechanism
If a mechanism error occurs, "M" is indicated on the
display.
MD disc is ejected from MD mechanism.
1-4-4 If mechanisms (CD/DECK/MD) error occur, the display
is indicated as follows.

If switches (open/close) error occur, "S" is indicated on
the display.

1-4-1 CD Mechanism
If a mechanism error occurs, "C" is indicated on the dis-
play.
1-4-2 DECK mechanism
When the initial condition becomes NG for the third
time, decide the error.
The error condition is displayed as "X" on the display.

The oscillation diagnosis(existence
of oscillation and measurement of
period) of a sub clock is performed
before the test mode is entered. If
the diagnosis result is OK, the sys-
tem enters the test mode. If the
diagnosis result is NG, the oscilla-
tion of the sub clock is diagnosed
again. If the result is OK, the sys-
tem enters the test mode. If the
diagnosis result is continuously NG
5 times,the system stops with
"ERR1" and "ERR2" displayed.

1. Preparation for Adjustment
You have to carry out the following test mode items if replace MD mechanism, pickup, head and pc board.
1-1 Procedure
1. Short-circuit #4(vss) and #7(wp) of IC1402(EEPROM).
2. Set the unit to test mode and carry out the every adjustment in test mode.
3. Stop the test mode by pressing the STOP key for 3 secs
4. Remove the short circuit of IC1402. Carry out reset start.
note: figures order of steps. - = no need.
* Result of EEPROM
OK_EEPROM Write the data of setting values and AUTO-pre adjustment perfectly.
WR_EEPROM Write the data of setting values perfectly however not write AUTO pre-adjustment.
Carry out AUTO-pre adjustment and write data to EEPROM.
NG_EEPROM Not write the data of setting values.
Check the connection of MD microprocessor and EEPROM.
** Carry out the TEST-PLAY , TEST-REC and C1 error in test mode after AUTO_ADJ and AUTO_FAB.
2. Test Mode
1. Holding down the MD rec button and turn the power on. (State A)
2. To enter the test mode stop state(State B), press the STOP button.
3. Load the playback disc 1(high reflection disc) or recording disc 2(low reflection disc).
