Cautions
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 Power 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. Initializing
1-1 Initialization Method
• While pressing the [POWER] key, turn the AC on.
1-2 Initialization Operation
• During the initial operation, the display shows "INI-
TIALIZE" and after that it will be returned to standby
condition.
• If any mechanisms error occurred, the error indication
is displayed as "ERR" in the display.
1-3 Mechanism Initializations
1CD Mechanism
• If a mechanism error occurred, the error indication is
displayed as "C ERR" in the display.
2Deck Mechanism
• If a mechanism error occurred, the error indication is
displayed as "X ERR" in the display.

4. Test Mode
4-1 Setting method of the Test Mode
• While pressing the "below each" key in the table, turn
the power switch on.
TEST MODE SETTING METHOD
CD MODE CD PLAY key+AC ON
DECK MODE TAPE PLAY key (3) +AC ON
✽ FCT & SUB CLOCK MENU key + AC ON
OSC DIAGNOSIS
✽ 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 system enters the test mode.
If the diagnosis result is NG, the oscillation 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.
4-2 Cancel of the test mode
• By turning the AC off, the system is initialized and
the test mode is canceled.
• Cancel the test mode only if the power switch is
turned off.
4-3 Contents of the Test Mode
• The muting during mode selection is not controlled
in the test mode.
• During the test mode, it can be operated in a special
manner that is different from an ordinary operation
by using the keys on the main body, specifically as
shown in the following tables.
