(Operating the system
Listening to a
program
1Turn on the audio/video
equipment connected to the
transmitter.
When the audio signals 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.)
2Put on the headphones and the
power turns on automatically. The
power indicator glows red when
the power turns on.
3Adjust the volume.
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.
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.
When no audio signal is received at
the transmitter input for more than
approximately five minutes
The transmitter will be turned off
automatically.
After listening to a program
Take the headphones off before the
transmitter turns off. 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.

The effective areas
of the transmitter
The illustration below shows the
approximate area covered by the
infrared rays emitted from the
transmitter.
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.
•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.
Replacing the Ear
Pads
When the ear pads become dirty or
damaged, consult your nearest Sony
dealer and replace them as illustrated
below.
Remove the old
ear pad by
pulling it out.
Place the new ear
pad around the
driver unit as
illustrated.
