Turn the VOL control dial to adjust
the volume.
If the infrared sensors of the
headphones are covered by your hands
when adjusting the volume, the
attenuate function will be activated and
volume cannot be adjusted. To adjust
the volume, move closer to the
transmitter of the monitor, or orient the
infrared emitters towards the
transmitter of the monitor.
Note
The volume of the headphones cannot be
adjusted with the car monitors or card
remote commander. Use the volume
control on the headphones.
Sound is automatically attenuated if
noise increases
— Attenuate function
If the infrared rays are obstructed, or the
headphones are used outside their effective
range, noise will increase and sound will
diminish. To avoid potential ear damage as
a result of noise, this function attenuates
any sound in the headphones. Sound is
automatically restored when you move
nearer to the transmitter or remove the
obstruction.
After listening to the programmes
Take off the headphones, and then turn off
the power (Noise may occur if you turn off
the monitor before taking off the
headphones).

Precautions
• The driver must not use the headphones.
It may lead to distraction and cause an
accident.
• If the headphones are used while
exposed to direct sunlight, sensitivity of
the infrared sensors may deteriorate, and
inferior quality sound may result.
• When the headphones are not to be used
for a long period of time, remove the
batteries to avoid damage caused by
battery leakage and subsequent
corrosion.
• Do not leave the headphones in a
location subject to direct sunlight, heat or
moisture (it is recommended to use the
headphones at a temperature of between
5 ˚C and 35 ˚C).
• Do not drop, hit or otherwise subject the
headphones to excessive shock of any
kind, as this could damage the product.
• If you leave the headphones in direct
sunlight, on a dash board etc., the battery
may leak and burst, and cause an injury.
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, lower 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
