Safety instructions
Safety instructions
• Please read this instruction manual carefully and completely before
using the devices.
• Make this instruction manual easily accessible to all users at all
times. Always include this instruction manual when passing the
devices on to third parties.
• Do not use the devices in situations which require special attention
(e.g. when performing skilled jobs).
• Always keep the devices dry and do not expose them to extreme
temperatures.
• Use the devices with care and set them up in a clean, dust-free
environment.
• Varnish or furniture polish may degrade the feet of the transmitter,
which could stain your furniture. You should therefore place the
transmitter on a non-slip pad to avoid potential staining of furni-
ture.
• This receiver allows you to set higher volumes than conventional
headphones. This can cause hearing damage in persons with healthy
hearing and especially in children.
• Refer all servicing to qualified service personnel. Servicing is
required if the devices have been damaged in any way, such as
mains cable or plug damage, liquid has been spilled, objects have
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.
• Use only the supplied mains unit.
• Disconnect the mains connector from the wall socket
– 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
– not operated near heat sources.

Putting the Set 830 S into operation
Setting up the transmitter
̈ Place 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.
̈ Make sure that the transmitter is placed as far as pos-
sible from your plasma TV screen.
̈ If 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.

Additional technical information
Compression (settings 1 and 3)
Deterioration of the ability to hear quiet sounds as well as loud ones is
a typical symptom of old age. Compression compensates for these
volume differences by boosting the volume of quiet sounds and
reducing the volume of loud sounds if necessary.
Compression seems to put the speech in the foreground, making it
easier to understand.
Compression is self-regulating; once it has been activated, it is not
necessary to make any other settings.
Treble boost (settings 2 and 3)
Another typical age-related phenomenon is the deterioration of the
hearing with regard to high frequencies. However, high frequencies are
important for the intelligibility of speech.
The treble boost makes the speech clearer and easier to understand.
With the treble boost (settings 2 and 3), additional fine adjustment is
possible using the treble boost control G on the rear of the trans-
mitter.
̈ Use a screwdriver to turn the treble boost
control G to the left or right until the sound
can be heard very well.
The position “0” corresponds to a minimum
boost, the position “MAX” corresponds to a
maximum boost, and the control is factory-
preset to the medium position.
G
Function of the treble boost control
By means of the transmitter’s steplessly adjustable treble boost
control G, the audio signal is boosted as shown in the diagram. The

Particularities of operating mode 2:
In operating mode 2, the transmitter is not switched on by the sound
signal from the sound source.
To switch the transmitter on:
̈ Take the receiver out of the charging compartment.
To switch the transmitter off:
̈ Place the receiver into the charging compartment.
If – in operating mode 2 – you want to use a second receiver and charge
its rechargeable battery during operation:
̈ Pull the battery out of the receiver’s battery
compartment 6.
̈ Slide the battery into the transmitter’s
charging compartment 9 as far as it will go.
