Problem Solution
Distortion If the transmitter is
connected to the headphones
jack, turn down the volume
of the connected audio/
video equipment.
(Around level 5 or 6 on the
volume control should be
appropriate.)
The headphones' power
indicator light is weak or
turned off.
• Charge the rechargeable
battery because the
headphones' battery is
weak, or if the power
indicator is still off after
charging the battery, take
the headphones to a Sony
dealer for a replacement
of the rechargeable
battery.
Loud
Move closer to the
background transmitter. As you move
noise 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.
Change the position or
angle of the transmitter.
• The headphones are used
by a window where the
sunlight is too strong.
n Draw the curtains/

direct sunlight, or use
the headphones away
from the sunlight.
