tional headphones. Protect your hearing from high volume levels.
Permanent hearing damage may occur when headphones are
used at high volume levels for long periods of time. Sennheiser
headphones sound exceptionally good and provide clear speech
intelligibility at low and medium volume levels.
왘 To prevent hearing damage, set the volume to a low level before
passing the product on to third parties.
왘 Do not use the product in an environment that requires your spe-
cial attention (e.g. in traffic or when performing skilled jobs).
왘 Always keep the headphones/MCA 800 charging adapter at
least 3.94" (10 cm) from cardiac pacemakers or implanted
defibrillators. The headphones/MCA 800 charging adapter contain/s magnets that generate a magnetic field which could cause
interference with cardiac pacemakers and implanted defibrillators.
왘 Do not use the product near water. To reduce the risk of fire or
electric shock, do not expose the product to rain or moisture.
왘 Keep the product, accessories and packaging parts out of reach
of children and pets to prevent accidents and choking hazards.
왘 Only use the power supply units supplied by Sennheiser.
Preventing damage to the product and malfunctions
왘 Always keep the product dry and do not expose it to extreme
temperatures to avoid corrosion or deformation. The normal
operating temperature is from 5 to 40 °C/41 to 104 °F.
왘 Use the product with care and store it in a clean, dust-free envi-
ronment.
왘 Switch off the product after use to conserve battery power.
왘 Unplug the power supply unit from the wall socket
– to completely disconnect the product from the power source,
– during lightning storms or

Important safety instructions
왘 Always ensure that the power supply unit is
– in a safe operating condition and easily accessible,
– properly plugged into the wall socket,
– only operated within the permissible temperature range,
– not exposed to direct sunlight for longer periods of time in
order to prevent heat accumulation.
왘 Varnish or furniture polish may degrade the feet of the transmit-
ter, which could stain your furniture. You should therefore place
the transmitter on a non-slip pad to avoid potential staining of
furniture.
왘 Do not operate the product near heat sources.
왘 Clean the product only with a soft, dry cloth.
왘 Use only attachments/accessories/spare parts supplied or rec-
ommended by Sennheiser.

Setting up the transmitter
왘 Choose a suitable place near your sound source.
왘 Separate the transmitter from other wireless devices in the room
by at least 50 cm/20" to avoid interference.
왘 Do not place the transmitter close to metal objects such as shelf
bars, reinforced concrete walls, etc. as this can decrease the
transmitter’s range.

Connecting the transmitter to an audio source
You can connect the transmitter either to a digital or an analog
audio source (e.g. a TV and a stereo hi-fi system).
If you connect an audio source to both inputs (digital and analog),
only the analog audio source will be reproduced.
You can also refer to the beginner’s video guides on how to
connect your digital wireless headphone system to a TV:
www.sennheiser.com/how-to-videos.
왘 Switch your audio sources off before connecting the transmitter.
왘 Check the connection possibilities of your audio source (audio
output, usually marked “OUT”).
왘 Select the corresponding connection cable and, if necessary, a
suitable adapter
왘 To connect the transmitter to your audio source, refer to the con-
nection diagram suitable for your audio source (see the following chapters). Follow the color codings on the transmitter and on
the cables.

3.5 mm headphone socket of your audio source.
PHONES
Adjust the volume of the headphone socket on your TV/audio
source to at least a medium level.
This improves the quality of wireless audio transmission. For
detailed information, please refer to the instruction manual of
your TV/audio source.
If the headphones socket on your audio source is a 6.3 mm/¼" jack
socket, you require an adapter (3.5 mm jack plug to 6.3 mm/¼" jack
plug, optional accessory) for the supplied 3.5 mm stereo audio
cable.
Some TV models mute the loudspeakers when you connect the
transmitter to the 3.5 mm headphone socket. Other TV models have
their own menu for adjusting the volume of the headphone socket.
Check the menu of your TV for information on how to deactivate the
muting function or adjust the volume. Alternatively, connect the TV
and the transmitter using a different connection possibility (A, C or
D).
