noise
The batteries
cannot be
charged.
Solution
Change the position or angle of the
transmitter.
• The headphones are used by a
window where the sunlight is too
strong.
t Draw the curtains/blind to shut
out the direct sunlight, or use the
headphones away from the
sunlight.
If the transmitter is connected to the
headphones jack, turn up the volume
of the connected audio/video
equipment.
The headphones’ power indicator
light is weak or turned off.
• Charge the headphone batteries or if
the power indicator is still off after
charging the headphone batteries,
take the headphones to a Sony
dealer for replacements of the
batteries.
When using more than two
transmitters, turn off the power of the
second transmitter or move it so that
the area covered by the infrared rays
does not overlap each other.
Noise is heard from the connected
audio equipment.
• Check if the INPUT SOURCE
selector is set to the correct position.
• Disconnect the connecting cord with
the power of the transmitter on and
check if the noise is heard from the
headphones. If the noise
disappears, the connected
equipment is the cause to make that
noise.
Check if the charge indicator lights
on. If not, put the headphones on the
transmitter correctly so that the
charge indicator lights on.

The transmitter of another headphone
system which does not employ the
noise reduction system is used with
the headphones of this system.
• Use the transmitter of this system.
Move closer to the transmitter. As
you move away from the transmitter,
more noise is likely to be heard. This
is inherent to infrared ray
communication and does not mean
that there is a problem with the unit
itself.
Check that there is no object between
the transmitter and the headphones.
Check that the infrared sensors are
not covered with your hands or hair.
