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.

As your headphones reduce outside sounds, it may
cause traffic accident. Also avoid using them where
hearing must not be impaired, for example, at a railroad
crossing, a site of construction, etc.

• Check the connection of the headphones and the AV

equipment.

• Check that the connected AV equipment is turned on.
• Turn up the volume of the connected AV equipment.

• Check if the battery has expired (the POWER

indicator dims). Replace the battery with a new one.

• If you cover the microphone of the headphones with

your hands, howling may occur.
In this case, move your hands away from the
