1. Initialization
1-1 Setting of initial conditions
While pressing the [SET] key, plug the AC power cord
into an AC power outlet.
1-2 Initializing operation
• A microcomputer is initialized for start when the AC
power is turned on while pressing the [SET] key. At
that time, CD mechanism, MD mechanism and CAS-
SETTE mechanism are also initialized.
• During the initial operation, the display shows "INITIAL-
IZE" and after that the clock blinks up on display.

1-4 Mechanism initialization
1-4-1 CD mechanism
• If a mechanism error occurs, "C" is indicated on the
display.
1-4-2 MD mechanism
• The MD ON code is input within 4 seconds after turned
the power port on, the MD initial code (D122H) is out-
put.
If the MD on code is not input, the error indication is
displayed as "M" on the display.
1-4-3 CASSETTE mechanism
• If a mechanism error occurs, "X" is indicated on the dis-
play.
