CIRCUIT DESCRIPTION
1. Initialization
1-1 Setting of initial conditions
While pressing the [ENTER] key, put the plug into an AC
power 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 mechanism and CASSETTE mechanism
are also initialized.
• During the initial operation,the display shows INITIALIZE
and after that it will be returned to STANDBY condition.
1-3 Initial items and back up data
*BACKED UP DATA
1-4 Mechanism initialization
1-4-1 CD mechanism
• Disc unclamps(traverse down).
• Rotary tray rotates(1/3 rotation).
• If a mechanism error occurs, CD ERR is indicated on the
display.
1-4-2 DECK mechanism
• When 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. CD & X ERR
