DANGER : Laser radiation when open and interlock defeated.
AVOID DIRECT EXPOSURE TO BEAM

Unplug the power cord from the power outlet then,
while holding the ENTER key depressed, plug the
power cord again.
÷Please note that resetting the microcomputer clears the
stored contents and returns to the factory set condition.
Operation to reset
The microcomputer may fall into malfunction (impossibility
tooperate,erroneousdisplay,etc.)whenthepowercordis
unplugged while power 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.

CIRCUIT DESCRIPTION
1. Initialization
1-1 Setting of the Initial Conditions
While pressing the [ENTER] key, plug the AC cord into AC
wall outlet.
1-2 Initializing Operation
• A Microcomputer is initialized for start when the AC power
is turned on when pressing the [ENTER] key.
At that time, CD and cassette mechanisms are also initial-
ized.
• During the initial conditions, the display shows *INITIAL-
IZE* and after that it will be returned to standby condition.

1-4 Mechanism Initialization
1-4-1 CD Mechanism
• If a mechanism error occurs *C ERR*is indicated on the
display.
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 ERR on the display.
1-4-3 Error display
• If both mechanism (CD/DECK) error occur, the display is
indicated as follows.

DIAGNOSIS
The oscillation diagnosis(existence of oscillation and measurement of period) of a sub clock is per-
formed 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
system enters the test mode. If the diagnosis result is continuously NG 5 times the system stops
with "ERR1" and "ERR2" displayed.

By turning the power off, the system is initialized and the test mode is canceled.

Then, it rewinds to the REC starting position and plays back automatically. If the
REC/ARM key is pressed, during the 4 seconds REC operation, the system records fur-
ther for 4 seconds, then returns to the starting position of the first 4 seconds REC opera-
tion and plays back.

CAUTION: For continued safety, replace safety critical com-
ponents only with manufacturer's recommended parts (refer
to parts list). indicates safety critical components. For con-
tinued protection against risk of fire, replace only with same
type and rating fuse(s). To reduce the risk of electric shock,
leakage-current or resistance measurements shall be carried
out (exposed parts are acceptably insulated from the supply
circuit) before the appliance is returned to the customer.
The DC voltage is an actual reading measured with a high
impedance type voltmeter. The measurement value may vary
depending on the measuring instruments used or on the prod-
uct. Refer to the voltage during PLAY unless otherwise speci-
fied; The value shown in ( ) is the voltage measured at the
moment of STOP.
