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 envi-  
ronment.  
• 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.

batteries with the appro-  
priate Sennheiser chargers.  
Do not expose  
to moisture.  
When not using the  
rechargeable battery for  
extended periods of time,

hour).  
Do not short-circuit.  
Only charge rechargeable  
batteries at ambient  
temperatures between  
10°C and 40°C.  
Do not mutilate  
or dismantle.

Putting the Set 830-TV into operation  
Putting the Set 830-TV 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.

Switching the receiver on/off  
Hearing damage due to high volumes!  
CAUTION!  
This receiver allows you to set higher vol-  
umes than conventional headphones. This  
can cause hearing damage in persons with  
healthy hearing and especially in children.  
̈ Before putting the receiver on, set the  
volume on the receiver to a low value.  
̈ Do not continuously expose yourself to  
high volumes.

Using the Set 830-TV  
Storing and charging the receiver  
Do not store the receiver on a glass dummy head, chair  
armrest, or similar for long periods of time as this can  
reduce the contact pressure of the earbows. Furthermore,  
with the earbows pulled apart, the receiver remains  
switched on.  
̈ After use, place the receiver into  
the transmitter’s charging compart-  
ment 4 without exerting too much  
pressure.  
When the receiver is placed correctly  
into the charging compartment, the  
indicator 7 lights up:

Notes:  
– With a fully charged battery, the operating time is up  
to 12 hours.  
– If you have several receivers, they can be used during  
charging.  
– Always store the receiver in the transmitter’s charging  
compartment 4 to ensure that it is fully charged. The  
intelligent battery charging technology prevents over-  
charging.

Using the Set 830-TV  
Charging a rechargeable battery  
in the transmitter’s charging compartment  
You can charge the receiver’s rechargeable battery or a  
spare BA 300 rechargeable battery (not included in the  
delivery of the Set 830-TV) in the charging compart-  
ment 5 at the side of the transmitter.  
The spare battery offers extended listening time while the  
discharged first battery is being recharged.  
Note:  
Before using the spare rechargeable battery for  
the first time, charge it for at least 3 hours.

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 C on the rear of the trans-  
mitter.  
̈ Use a screwdriver to turn the treble boost  
control C 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.

Function of the treble boost control  
By means of the transmitter’s steplessly adjustable treble boost

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 3.  
̈ Slide the battery into the transmitter’s  
charging compartment 5 as far as it will go.
