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.

Replacing the ear pads

When the ear pads become dirty or damaged,
you can get replacements from your Sony dealer.
Replace them as illustrated below.

1

Remove the old ear pad by pulling it
out of the groove on the housing.

2

Place the new ear pad on the driver
unit and insert the edge of the pad into
the groove as illustrated.

Make sure that the entire edge of the ear pad is
securely inserted into the groove.
