Tips for charging
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. charging time Approx. usage time1)
3 hours2) 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.
