RF
signal transmission area
The approximate
RF
signal transmission area from the processor is
up
to
30
m.
The processor detects the
optimum
frequency automatically
when
the
headphones
are
removed
from the processor. The
sound
may
be
interrupted
if the
headphones
are
out
of
RF
signal transmission area
or
reception conditions deteriorate.
In
this case,
move closer to the processor
or
press
TUNE/ID
SET
on
the
processor
and
headphones
to
have
them
detect the
optimum
frequency again. See
"If
a beep
sound
is
heard
from the
headphones"
(page
21)
on
how
to detect the
optimum
frequency.
Notes
• Because this system transmits signals
at
2.4 GHz,
sound
may
be
interrupted
if interference
occurs. This is
due
to radio frequency characteristics,
and
is
not
a malfunction.
•
Any
noise
you
hear
through
the
headphones
may
vary
depending
on
the processor position
and
room
conditions.
It
is recommended
that
you
place the processor
in
a location
that
produces
the clearest sound.
•
Sound
may
be
interrupted
if
the processor is
used
with
other
wireless
apparatus
using 2.4
GHz
frequency,
or
a microwave oven.
If
an
audio
signal
is
not
input
for
5
minutes
RF
signal transmission from
the
processor automatically stops
when
an
audio signal
is
not
input
for 5 minutes. The
RF
signals are automatically transmitted
when
an
audio signal is
input
again.
RF
signal transmission
may
stop
when
an
extremely
low
sound
is
input
for
about
5 minutes.
If
this happens, raise the volume of the connected
audio
or
video
component
and
lower the volume of the headphones.
If
signal noise is
output
from a component connected to the LINE
IN
jacks,
RF
signal transmission
may
not
stop.
Tip
If
RF
signal transmission from the processor stops
when
an
audio
signal is
not
input
for 5
minutes, the
RF
signals are automatically transmitted
when
an
audio
signal is
input
again.
The
RF
indicatorblinks
and
the processor detects the
optimum
frequency for transmission.
If
the
transmission frequency changes after the
RF
indicator lights
up
and
no
sound
is heard, press
TUNE/ill
SET
on
the
headphones
once
and
tune
to the
new
frequency.
Notes
• The
headphones
should
be
used
within
the
RF
signal transmission area (see "RF signal
transmission area").
• The
surround
sound
effect
may
not
be
obtained from
sound
sources
that
do
not
incorporate
video,
such
as music CDs.
• This system simulates the average HRTF* common to
most
people. However, the effect
can
differ from
person
to
person
since the HRTF can
vary
between
individuals.
