Notes on receiving performance
This system utilizes very high frequency signals in the 800 MHz band so the receiving performance may deteriorate due to the surroundings. The following examples illustrate conditions that may reduce the reception range or cause interference.
•Inside a building with walls containing steel beams.
•An area with many steel file cabinets, etc.
•An area with many electrical appliances capable of generating electromagnetic fields.
•The transmitter is placed on a metal instrument.
•An area facing a roadway.
•Noise or interfering signals exist in the surroundings due to radio transceivers in trucks, etc.
•Noise or interfering signals exist in the surroundings owing to wireless communication systems installed along roadways.

The effective areas of the transmitter
The optimum distance is up to approximately 100 m without the system picking up some interference. However, the distance may vary depending on the surroundings and environment. If the system picks up some noise within the above mentioned distance, reduce the distance between the transmitter unit and the headphones, or select another 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 spots) where the RF signal cannot be received. This characteristics is inherent to RF signals, and does not indicate malfunction. By slightly moving the transmitter, location of the dead spot can be changed.
If you have any questions or problems concerning the system that are not covered in this manual, please consult your nearest Sony dealer.
Be sure to bring the headphones and the transmitter to the Sony dealer when requiring repair work.
