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.
C

X
S
ERR
1-4-5 TAPE door switch diagnosis
If switches (open/close) error occur, "S" is indicated on
the display.
1-4 Mechanism Initialization
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.
