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.
Precautions
• Before operating the system, check that the
operating voltage of your system is identical with
the voltage of your local power supply.
• The CE mark on the unit is valid only for
products marketed in the European Union.
• When the headphones is not to be used for a long
period of time, remove the battery to avoid
damage caused by battery leakage and
subsequent corrosion.
• 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 headphones
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.
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.
