Precautions
• 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
and remove the batteries to avoid damage
caused by battery leakage and subsequent
corrosion.
• Do not leave the wireless stereo headphones
system in a location subject to direct sunlight,
heat or moisture (It is recommended to use the
headphones at a temperature of between 5˚C
and 35˚C (between 41˚F and 95˚F).)
• Do not drop, hit or otherwise subject the
transmitter or headphones to strong shocks of
any kind. This could damage the product.
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.

Solution
Turn on the transmitter first, and then
put on the headphones.
Check the connection of the audio/
video equipment or the AC power
adaptor.
Check that the audio/video
equipment connected to the
transmitter is turned on.
If the transmitter is connected to the
headphones jack, raise the volume of
the audio/video equipment
connected to the transmitter.
Change the radio frequency with the
CHANNEL selector on the
transmitter, then press the TUNE
button again.
The mute function is activated.
Use the headphones near the
transmitter.
The headphones’ power indicator
light dims, flashes or goes off.
• Charge the rechargeable batteries if
the headphones’ batteries are weak,
or replace dry batteries with new
ones. If the power indicator is still
off after charging the batteries, take
the headphones to a Sony dealer.
If you connect the transmitter to the
LINE OUT or REC OUT jacks of an
audio reproducer, make sure that the
NOISE FILTER switch is set to OFF.
Make sure that the NOISE FILTER
switch is set to either ON or OFF (If
the switch gets stuck between ON and
