If
you cannot receive a clear
audio
signal Noise Reduction process
First change the radio frequency with the
CHANNEL
selector switch on the
transmitter,then briefly press the
AUTO
TUNING
button on the headphones. The transmitter compresses
the
audio signal and converts
it
to
RF
signal. The
headphones convert the received
RF
signal
to
an
audio signal and decompresses
it
.This
process reduces noise picked up during transmission.

Tips for charging
Charge supplied battery first
The supplied rechargeable nickel-metal hydride battery
is
not charged from the first
time
you use
it
.
Be
sure
to
charge them before use.
About auto charge function
Placing the headphones on the transmitter automatically
turnsthem
off
,then charging starts. This eliminates the
need for turning
on/off
every
time
you wear and take
off
the headphones.
If
CHARGE/RED indicator does not
light up red
-Check
if
the right and left headphones are rested on the
transmitter correctly.
Take
off
the headphones and place
them
on the transmitter again
so
that
the headphones'
contact points meetthe transmitter's contact pins.
-Charging may not be completed
if
the transmitter's
contact pin and headphones' contact point are dusty.
Wipe
them
with a cotton bud, etc.

or
noisy.
Notes
-The battery capacity may decrease
if
the headphones
are turned on and placed on the transmitter with the
AC
adaptor disconnected.
-The transmitter automatically turns
off
while charging
the headphones.
-This system
is
designed
to
charge only the supplied
rechargeable battery

for safety.Note
that
other types
of
rechargeable battery cannot be charged
with this system.
-Ifdry batteries

You
can
order the battery from the store where you
purchased this system, or at your nearest Sony dealer.

Do
not touch the contact pins
of
the transmitter.Ifthe
contact pins become dirty, charging may not be
possible.
-Charging may
not

Wipe them with a cotton bud, etc.
Using
the
headphones
with separately-sold
dry
batteries
Commercially available
(LR03
(size AAA)) dry batteries can
also be used
to
powerthe headphones. Install
two
batteries
in
the same manner
as
described in step 1
of
"How
to
use
."
If
you
attempt
to charge the headphones with dry
batteries installed,the
CHARGE/RED
indicator lights up
red
for
15
seconds,then turns off. The battery charge
function
is
not
activated.

Tips for connection
-When you connect the stereo mini cable (stereo mini
jack) directly
to
an
earphone jack (monaural mini jack),
the audio signal may not be
output
through the right
channel.
Tips for volume setting
-Ifyou connect the transmitter to the headphone jack
of
the
A/V
component, set the volume
of
the
A/V
component
as
high
as
possible
but
not so high
that
the
audio signal becomes distorted.
-When watching videos, be careful not
to
raise the
volume too high in quiet scenes.
You
may hurt your ears
when a loud scene
is
played.

Tips for better reception
Receiving performance
Thi
s system utilizes very high frequency signals
in
the
900
MHz band
so
the receiving performance may deteriorate
due
to
the surroundings.The following examples illustrate
conditions
that
may reduce the reception range
or
cause
interference.
-Inside a building with walls containing steel beams
-An area with many steel file cabinets, etc.
-
An
area with many electrical appliances capable
of
generating electromagnetic fields
-The transmitter
is
placed on a metal instrument.
-An area facing a roadway
-Noise
or
interfering signals exist
in
the surroundings due
to
radio transceivers
in
trucks, etc.
-Noise
or
interfering signals exist in the surroundings
owing
to
wireless communication systems installed
along roadways.
Effective area
of
the
transmitter
The
optimum
distance
is
up
to
approximately 45 m
(150
ft)
without
the system picking up some interference.
However, the distance may vary depending on the
surroundings and environment.
-Ifthe system picks up some noise within the above
mentioned distance, reduce the distance between the
transmitter and the headphones, or select another
channel.
-When you use the headphones inside the effective area
of
the transmitter, the transmitter
can
be placed
in
any
direction from the listener.
-
Even
within the signal reception area, there
are
some
spots (dead spots) where the
RF
signal cannot be
received. This characteristic
is
inherent
to
RF
signals, and
does
not
indicate malfunction.
By
slightly moving the
transmitter, location
of
the dead spot
can
be changed.
Replacing
the
earpads
The earpads are replaceable.
If
the earpads become
dirty
or worn
out
, replace
them
as
illustrated below. The
earpads are not commercially available.
You
can
order
replacements from the store where you purchased this
system,
or
at your nearest Sony dealer.
Remove the old earpad by pulling
it
out
of
the groove
on the housing.
2
Fit
the new earpad in the groove
of
the housing.
Make sure the earpad
is
set
to
the vertical position.
Precautions
-When this system
is
not
to
be used for a long period
of
time, disconnect the
AC
adaptor from the
AC
outlet
holding the plug, and remove the battery from the
headphones
to
avoid damage caused by battery
leakage and subsequent corrosion.
-
Do
not
leave this system in a location subject to direct
sunlight, heat
or
moisture.
-
You
may hear some noise when you disconnect the
AC
adaptor from the transmitter before taking
off
the
headphones.
Avoid ~sing headphones at high volume. Hearingexperts
advise against continuous, loud and extended play.Ifyou
experience a ringing in your ears, lowerthe volume or
discontinue use.
Caring for others
Keep
the volume at a moderate level. This will allow you
to
hear outside sounds and
to
be considerate to the
people around you.
Ifyou have any questions or problems concerning the
system
that
are not covered in this manual, please consult
your nearest Sony dealer.
Be
sure
to
bring the headphones and the transmitter
to
the Sony dealer when requiring repair work.
