Sending RF signals from the transmitter

The transmitter starts sending RF signals automatically when it detects an audio signal from the equipment connected. If it does not detect an audio signal for more than about four minutes, the transmitter will stop sending RF signals, and the power indicator will turn off. When the transmitter receives an audio signal again, it starts sending the RF signals, and the power indicator will light in green again. If the audio signal is very weak, the transmitter does not send RF signals. If the transmitter is connected to a headphone jack, make sure the volume of the equipment connected is set to 5 – 6 or higher. You may not hear the beginning of the sound from the headphones until the transmitter starts sending the RF signals after detecting an audio signal.

Notes

• If hiss is heard, move closer to the transmitter.

• You may hear some noise when you disconnect the AC power adaptor from the transmitter before taking off the headphones.

Effective coverage of

Replacing the ear pads

the transmitter

The maximum distance is up to approximately 100 m without the system picking up any 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 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 spot) 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 spot can be changed.

The ear pads are replaceable. If the ear pads become dirty or worn out, replace them as illustrated below. The ear pad is not commercially available. You can order replacements from the store where you purchased this system, or at your nearest Sony dealer.

1 Remove the old ear pad by pulling

it out of the groove on the housing.

2 Place the new ear pad on the driver

unit and insert the edge of the pad into the groove as illustrated.

Make sure that the entire edge of the ear pad is securely inserted into the groove.

N Additional information

Precautions

• If the transmitter is not to be used for a long

period of time, disconnect the AC power adaptor from the AC outlet by holding the plug. Do not pull on the cord.

• Do not leave the wireless stereo headphone

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.
