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.
After listening to a program
Take the headphones off before turning off the
headphones and the transmitter. Otherwise you
may hear some noise when the infrared rays are
suddenly cut off.
Note

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.

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.
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.
