fallen inside, the devices have been exposed to rain or moisture, do
not operate properly or have been dropped.
• WARNING: To reduce the risk of fire or electric shock, do not expose
the device and the mains unit to rain or moisture.

– to completely disconnect the device from the mains,
– during lightning storms or when unused for long periods of time.
• Ensure that the mains unit is:
– always readily operable and easily accessible,
– properly plugged into the wall socket,
– not covered or exposed to direct sunlight for longer periods of
time in order to prevent heat accumulation,
– only operated within the permissible temperature range (see
“Specifications” on page 27),

Putting the Set 830-TV into operation
Putting the Set 830-TV into operation
Setting up the transmitter
왘Place the transmitter so that:
– there are no obstacles in the light path between trans-
mitter and receiver and
– transmitter and receiver are not exposed to direct sun-
light. Direct sunlight may interfere with the reception
and may damage the transmitter.
If you are using a plasma TV screen:
Plasma TV screens radiate an infra-red signal that can
adversely affect the transmission quality.
왘Make sure that the transmitter is placed as far as pos-
sible from your plasma TV screen.
왘If necessary, use a standard extension cable (3.5 mm
stereo jack plug) to reduce the distance between trans-
mitter and receiver. This extension cable is available from
your Sennheiser dealer.
Note:
One transmitter can be used to transmit to several
receivers on the same frequency.
