Check the remaining power of the
headphones’ battery

Pull up the self adjusting band, and check
that the headphones’ power indicator lights
in red. You can now use the headphones.
Charge the battery or install a new dry
battery, if the power indicator light is weak
or turned off and the sound becomes
distorted or has a lot of noise.

( Operating the system

Listening to a
program

1 Turn on the audio/video equipment

connected to the transmitter.

When the audio signal is input, the
transmitter turns on automatically and
the infrared emitters glow. If the
transmitter is connected to the
headphone jack, set the volume control
of the audio source equipment as high
as possible but not so high that the
audio signal gets distorted. (Around
level 5 or 6 on the volume control
should be appropriate.)

Notes

•During recharging, the transmitter is turned off

automatically.

•When the life of the rechargeable battery is

shortened by half even after a proper
recharging, take the headphone set to a Sony
dealer and have the old rechargeable battery
replaced by a new one.

Removing the battery

1 Open the battery compartment lid.
2 Remove the battery from the battery

compartment.

Auto power on/off function

When you remove the headphones, the
power turns off automatically. Do not pull
up the self adjusting band when not using
the headphones, otherwise the headphones
will be switched on.

The effective areas
of the transmitter

The illustration below shows the
approximate area covered by the infrared
rays emitted from the transmitter.

Mute function

If a hissing noise is heard when the infrared
rays are obstructed, or the headphones are
used outside of the effective range (see the
next section), the mute function will be
activated and the sound will not be heard
from the headphones. To restore the
sound, move nearer toward the transmitter
or remove the obstruction.

If no audio signal is received at the
transmitter for more than
approximately five minutes, the

transmitter turns off automatically.

After listening to a program, take the
headphones off before the transmitter turns
off and rest them on the transmitter.
Otherwise you may hear some noise when
the infrared rays are suddenly cut off.

Note

The infrared emitters light up when the
transmitter is turned on. The brightness of the
emitters may not be uniform, however, this is not
a malfunction.

Notes

•If you use the headphones at too great a
distance from the transmitter, you may hear a
hissing noise and if there is an object between
the receiver and the transmitter, the sound may
be interrupted. These phenomena are inherent
to infrared ray communication and do not
mean that there is a problem with the unit
itself.

•Do not cover the infrared sensors with your
hands or hair.

•The infrared rays will not penetrate walls or
opaque glass, therefore, be sure to stay within
sight of the transmitter.

•When you use the headphones inside the area
illustrated in the diagrams, the transmitter can
be placed in the front, behind or by the side of
the listener.

( Additional information

Replacing the ear
pads

When the ear pads become dirty or
damaged, you can get replacements from
your Sony dealer. Replace them as
illustrated below.

1 Remove the old ear pad by pulling it off

from the driver unit.

2 Place the new ear pad around the driver

unit as illustrated.

Precautions

• The CE mark on the unit is valid only for

products marketed in the European
Union.

• When the transmitter is not to be used for

a long period of time, disconnect the AC
power adaptor from the AC outlet
holding the plug. Do not pull on the
cord.

• Do not leave the cordless stereo

headphone system in a location subject to
direct sunlight, heat or moisture.

Notes on headphones
Preventing hearing damage

Avoid using headphones at high volume.
Hearing experts advise against continuous,
loud and extended play. If you experience
a ringing in your ears, reduce the 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.

10

If you have any questions or problems
concerning the system that are not covered
in this manual, please consult the nearest
Sony dealer.

Be sure to bring the headphones and the
transmitter to the Sony dealer when
requiring repair work.

Troubleshooting

No sound/Muffled sound

/ Turn on the transmitter first, then put on

the headphones.

/ Check the connection of the audio/video

equipment or the AC power adaptor.

/ Check that the input select switch position

is correct.

/ Check that the audio/video equipment is

turned on.

/ Turn up the volume on the connected

audio/video equipment, if the transmitter
is connected to the headphones jack.
(Around level 5 or 6 on the volume control
should be appropriate.)

/ The mute function is activated.

• Check if there is any object between the
transmitter and the headphones.

• Use the headphones near the transmitter.

• Change the position and angle of the
transmitter.

/ The headphones’ power indicator light is

weak or turned off.

• Charge the rechargeable battery because
the headphones’ battery is weak, or if the
power indicator is still off after charging
the battery. Take the headphones to a
Sony dealer for a replacement of the
rechargeable battery.

• If you are using the conventional dry
battery, replace it with a new one.

/ When the LINE OUT jack of your audio/

video equipment is connected to PHONES
IN (A) of the transmitter, the sound will be
low. Connect the LINE OUT jack to the
LINE IN (B) as described in “Setting up the
transmitter.”

Distortion

/ If the transmitter is connected to the

headphones jack, turn down the volume of
the connected audio/video equipment.
(Around level 5 or 6 on the volume control
should be appropriate.)

/ The headphones’ power indicator light is

weak or turned off.

• Charge the rechargeable battery because
the headphones’ battery is weak, or if the
power indicator is still off after charging
the battery. Take the headphones to a
Sony dealer for a replacement of the
rechargeable battery.

• If you are using the conventional dry
battery, replace it with a new one.

/ When the headphones jack output is

connected to the LINE IN (B) of the
transmitter, increasing the volume of the
connected audio/video equipment may
cause distortion. Connect the headphones
jack output instead to PHONES IN (A) as
described in “Setting up the transmitter.”

Loud background noise

/ Move closer to the transmitter. As you

move away from the transmitter, more
noise is likely to be heard. This is inherent
to infrared ray communication and does
not mean that there is a problem with the
unit itself.

/ Check that there is no object between the

transmitter and the headphones.

/ Check that the infrared sensors are not

covered with your hands or hair.

/ Change the position or angle of the

transmitter.

• The headphones are used by a window
where the sunlight is too strong.
n Draw the curtains/blind to shut out

the direct sunlight, or use the
headphones away from the sunlight.

/ If the transmitter is connected to the

headphones jack, turn up the volume of the
connected audio/video equipment.
(Around level 5 or 6 on the volume control
should be appropriate.)

/ The headphones’ power indicator light is

weak or turned off.

• Charge the rechargeable battery because
the headphones’ battery is weak, or if the
power indicator is still off after charging
the battery. Take the headphones to a
Sony dealer for a replacement of the
rechargeable battery.

• If you are using the conventional dry
battery, replace it with a new one.

The battery cannot be charged

/ Check if the charging indicator lights on. If

not, put the headphones on the transmitter
correctly so that the charging indicator
lights on.
