Operation to reset
The microcomputer may fall into malfunction (impossibil­ity 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 condi­tion.
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.

CIRCUIT DESCRIPTION

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.

CIRCUIT DESCRIPTION

4-2 MD SECTION

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
