is turned on when pressing the [ENTER] key. At that time,
CD and cassette mechanisms are also initialised.
• During the initial conditions, the display shows (INITIAL-
IZE( and after that it will be returned to standby condition.

• 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.

SUB CLOCK OSC
DIAGNOSIS
MENU key + AC -ON
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
