The effective areas of the transmitter
The optimum distance is up to approximately 130 feet (40m) without the system picking up some interference. However, the distance may vary according to the surroundings and environment. If the system picks up some noise while using it within the above mentioned distance, reduce the distance between the transmitter unit and the headphones, or select the other channel.
Notes
•When you use the headphones inside the effective areas 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 point) where the RF signal can not be received. This characteristics is inherent to RF signals, and does not indicate malfunction. By slightly moving the transmitter, location of the dead point can be changed.
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 out of the groove on the housing.

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.
