6. Muting Output
In
order
to
prevent
generation
of
abnormal
sound
at
time
of
key
operation,
muting
signal
is
transmitted
from
the
MUTE
terminal
at
the
timings
shown
in
the
following
diagrams.
@
Muting
output
time
at
time
of
restoration
from
the
inhibit
state
or
band
switching
is
extended
to
about
2
times
of
that
in
normal
cases.
(This
is
also
true
when
a
band
is
changed
according
to
the
memory
read
in
the
random
memory
system.)
@
When
the
multiple
band
input
keys
are
pushed
or
during
the
fast
forwarding
or
auto
search
tuning,
muting
output
is
kept
at
‘’H”
level.
@
The
receiving
channel
(division
of
the
programmable
counter)
changes
12
mS
later
after
muting
signal
is
transmitted.
This
will
provide
a
margin
to
muting
application
time.
