If the CHG indicator is not lit
The indicator will not light up if the headphones' contact
point does not meet the transmitter's contact pin. In this
case, remove the headphones and insert them in the
transmitter again so that the indicator lights up.
To recharge the headphone battery after use
Place the headphones on the transmitter after use. The CHG
indicator lights up, and then charging starts.
When charging is complete, there is no need to remove the
headphones from the transmitter after charging has
completed.
Notes
 The transmitter automatically turns off while charging the battery.
 Avoid exposure to temperature extremes, direct sunlight, moisture,
sand, dust or mechanical shock.
 If the headphones are used outside the recommended temperature
range, the CHG indicator flashes and charging stops. Charge in an
environmental temperature of between 5°C and 35°C.
 If you haven't used the headphones for a long period of time, the
life of the rechargeable battery may become short. This will
improve when you repeat the charging and discharging process
several times.
 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.
 Do not store the headphones in hot places for a long period of time.
When storing it for more than a year, charge the battery once a year
to prevent over discharge.
 Do not touch the contact pin of the transmitter. If a contact pin
becomes dirty, charging may not be possible.
 Charging may not be completed if the transmitter's contact pin and
headphones' contact point are dusty. Wipe them with a cotton bud,
etc.

The optimum distance is up to approximately 100 m without
the system picking up some interference. However, the
distance may vary depending on the surroundings and
environment. If the system picks up some noise within the

Notes on headphones
To reduce the risk of 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
your nearest Sony dealer.
Be sure to bring the headphones and the transmitter to the
Sony dealer when requiring repair work.
