NOTES:
1.
The
input
signal
is
activated
by
the
fall
of
LI’.
2.
The
output
is
maintained
until
the
next
input
signal.
3.
ARisa
control
input
terminal
and
the
REC
output
is
not
“H”
when
AR
=
“L”.
4,
When
AR
=
“L”
signal
is
supplied
during
the
REC
output
is
“H”,
REC
output
becomes
“L”.
5.
At
the
moment
the
power
is
on,
all
output
will
be
“L”
and
the
Stop
mode
will
be
effected.
4)
Regarding
the
input
circuit’s
diode
D13
Previously
M54410P
has
been
so
designed
that
the
first
terminal
was
PLAY
input
and
the
sixth
terminal
was
PAUSE
input.
But
in
GX-635D,
PLAY
is
used
for
REV
and
PAUSE
for
FWD.
Consequently,
grounding
only
the
6th
terminal
(FWD)
will
not
allow
the
modes
to
be
changed
directly from FF or RWD to FWD. For this
reason, the first terminal (REV) is also gounded
through diode D13 releasing FF and YWD. In
addition, even if there are simultaneous inpsts into
both FWD and REV, FWD mode at put is
designed to take priority.
