NOTICE FOR THE CUSTOMERS IN THE
U.S.A.
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception,
which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and
receiver.
 Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
 Consult the dealer or an experienced radio/TV
technician for help.
Audio out
(L/R) jacks
If no signal or low signal is input for
about 10 minutes
If the transmitter detects no signal, the POWER indicator of the
transmitter blinks for about 10 minutes, then the transmitter stops
the RF signal transmission automatically*. The transmitter restarts
after receiving an audio signal again.
The transmitter may also stop if the volume of the connected A/V
component is too low. In this case, raise the volume of the
connected A/V component within the range where the sound is
not distorted, then lower the volume of the headphones.
* If signal noise is output from the connected A/V component, the
transmitter may not turn off, even when no audio signal is input.
Using the unit by connecting the supplied cable
Storing the headphones
You can use the unit as ordinary wired headphones by connecting the supplied connecting cable. You can also
charge the headphones during wired use. Be sure to use the supplied connecting cable.
To reduce the risk of hearing damage, lower the volume of the A/V component before connection.
Check right and left of the headphones before swiveling to store.
You are cautioned that any changes or modifications not
expressly approved in this manual could void your
authority to operate this equipment.

Replacing the earpads
Listening to audio from the
headphones and TV speakers
simultaneously
The earpads are replaceable. If the earpads become dirty
or worn out, replace them as illustrated below. The
earpads are not commercially available. You can order
replacements from the store where you purchased this
system, or at your nearest Sony dealer.
Connect the transmitter to your Cable Box/Satellite Box
rather than your television.
Some TVs can be set to output audio from both its
speakers and headphone jack. For details on the
setting, refer to the operating instructions of your TV.
Remove the old earpad by pulling it out of the groove
on the housing.
Unified
polarity plug
Fit the new earpad in the groove of the housing.
Make sure the earpad is set to the vertical position.
Charge the headphones first
The headphones contain a rechargeable Lithium-Ion
battery, which should be charged before using for the first
time.
Charging and usage time
Approx. usage time1)
10 hours3)
1) at 1 kHz, 0.1 mW + 0.1 mW output
2) hours required to fully charge an empty battery
3) Time may vary, depending on the temperature or
conditions of use.
Remaining battery
To check the remaining battery charge of the headphones,
turn them on, and check the / indicator. The battery is
still serviceable when the indicator lights up green. Charge
the headphones if the / indicator turns off, dims,
flashes, or the sound becomes distorted or noisy.
To charge the headphones from an
AC outlet
If you recharge the headphones by connecting to an AC
outlet, use the USB Charging AC Power Adaptor AC-UD11
(not supplied). For more information, refer to the
operating instructions supplied with the adaptor.
Notes
 Use only the supplied micro-USB cable. Do not use any
other USB cable.
 If the headphones are not used for a long time, the CHG
indicator may take a while to light after you connect it
to the computer. In this case, do not disconnect the
micro-USB cable from the headphones and wait until
the CHG indicator lights up.
 Charge the headphones in an ambient temperature of
between 5 °C to 35 °C (41 °F to 95 °F). If you try to
charge the headphones in an ambient temperature
outside this range, the CHG indicator may flash and
charging will not be completed properly.
 If the computer enters hibernation mode while
connected to the headphones, charging will not be
completed properly. Check the setting of the computer
before charging. The CHG indicator will turn off
automatically when the computer enters hibernation.
Charge the headphones again in this case.
 Connect the headphones directly to a computer.
Charging may not be completed properly by an indirect
connection, such as via a USB hub.
 When the battery life reduces to half, this may be the
end of battery lifetime. For how to change batteries,
consult your place of purchase or a Sony dealer.
Tips for volume setting
 If you connect the transmitter to the headphone jack of
the A/V component, set the volume of the A/V
component as high as possible but not so high that the
audio signal becomes distorted.
 When watching videos, be careful not to raise the
volume too high in quiet scenes. You may hurt your
ears when a loud scene is played.
RF signal transmission
area
The approximate RF signal transmission area from the
transmitter is up to 30 m (100 ft).
The sound may be interrupted if the headphones are out
of RF signal transmission area, or reception conditions
deteriorate.
Notes
 Because this system transmits signals at 2.4 GHz, sound
may be interrupted if interference occurs. This is due to
radio frequency characteristics, and is not a
malfunction.
 Any noise you hear through the headphones may vary
depending on the transmitter position and room
conditions. It is recommended that you place the
transmitter in a location that produces the clearest
sound.
 Sound may be interrupted if the transmitter is used
with other wireless apparatus using 2.4 GHz frequency,
or a microwave oven.
 Be sure to always use the supplied AC adaptor. Even AC
adaptors having the same voltage and plug polarity can
damage this product due to the current capacity or
other factors.
On power sources and placement
Tips for charging
3 hours
 Do not drop, hit, or otherwise expose the headphones
to strong shock of any kind. This could damage the
product.
 Do not disassemble or attempt to open any parts of the
system.
 Insert the AC adaptor plug firmly.
 Be sure to use the supplied AC adaptor. Using AC
adaptors with different plug polarity or other
characteristics can cause product failure.
If you connect the transmitter directly to an earphone
jack (monaural mini jack) of an A/V component, the
audio signal may not be output through the right
channel.
