When 33PIN(SYSTEM DOWN) becomes [L] to enter the
backup mode due to service interruption or pulling-out of the
AC cord, etc, the present disc address will be memorized until
the RESET is ON.
If 44PIN MECHA UP SW shows [H] when POWER is turned
ON again, power supply may have been cut during the
turntable rotation. The turntable address detection mode will
start to detect the
disc address 1 again.
a) Incase of 44PIN MECHA UP SW = [H], and 47PIN CLOSE SW
=[L]
Aftertheturntable is moved to the position where 46PIN OPEN
MTR isset at [H] and CLOSE
SWat
[H], theturntable is rotated.
After the address detection, the Mecha UP state is attained.
b) In case of 44PIN MECHA-UP SW
=[H], and 47PIN CLOSE SW
=[H]
45PIN CLOSE MTR is set at and the tray is closed.
Simultaneously
the
turntable
is
rotated
to
detect
the
