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.

• If you are not going to use the unit for a long
time, remove the battery to avoid damage
from battery leakage or corrosion.
Checking the remaining battery
power
Pull up the self-adjusting band and check the
power indicator located on the upper part of the

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 red 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.
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
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.
Replacing the ear pads
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.
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.
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.

Troubleshooting
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.
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.
