While pressing the [ENTER] key, plug the AC cord into
the AC power outlet.
1-2 Initializing operation
• A microcomputer is initialized for start when the AC
power is turned on while pressing the [ENTER] key. At
that time, CD mechanism and
nism are also initialized.
• During the initial operation, the display shows “INITIALIZE” and after that the clock blinks up on display.
