Set 820
Thank you for choosing Sennheiser! Over half a century of accumulated
expertise in the design and manufacture of high-quality audio equipment

has made Sennheiser a world leader in the field of audiology.
The Set 820 is an assistive listening system for your radio, TV, hi-fi system or

similar sound sources at the volume you choose. The transmitter has a range
of up to 100 m which allows you to move around freely – without the
constrictions of cables. The system uses RF audio signals for sound
transmission.

24

Connecting the transmitter (charging unit)
The rear of the transmitter is

fitted with two audio inputs:
A socket (LINE) for connection
to the audio output or the
headphone socket on your TV,
and a microphone socket (MIC).

Plug in one end of the connecting cable to the audio output or the
headphone socket on your TV, and the other end to the LINE socket on the
transmitter.

If your TV set is fitted with a SCART socket, use the supplied adapter.
If your TV does not have a headphone or SCART socket, you can use an

external microphone which is described in the section “Accessories”.

English

25

Only use one of the two audio inputs on the transmitter (MIC or LINE).
Connect the power cable to the POWER socket on the transmitter. Plug the

power supply into a household electrical outlet.
Pull the power supply unit out of the electrical outlet when the unit will not

be used for extended periods of time.

English

Complete freedom of movement
It is not necessary that the transmitter and

stethoset receiver are in a direct line of
sight, so you can move around freely in the
home or outside in the garden. One
transmitter can be used to transmit to
several receivers on the same frequency.
The transmitter’s range may decrease due
to the surface/composition of walls.

26

Where to place the transmitter
Choose a suitable place near or on

top of your hi-fi system or TV set.
Do not place the transmitter close

to metal objects such as shelf bars,
reinforced concrete walls, etc.

The transmitter features a
convenient automatic on/off
function. The transmitter is
turned on by the audio signal.
If there is no audio signal for about 3 minutes, the transmitter automatically
turns off. The transmitter is now in stand-by mode, its power consumption is
very low so that it can remain connected to the mains. Batteries can always
be recharged when the transmitter is connected to the mains.

27

English

Using the stethoset receiver
When putting the stethoset receiver on,

make sure the operating control is
pointing downwards and the letters are
at the front.

The stethoset receiver automatically
turns on if you pull the earbows apart.

English

After use, the receiver automatically
turns off.

28

Adjusting the volume
Adjust the receiver’s volume with

the operating control.
If you are not using the stethoset

receiver, store it in the transmitter’s
charging compartment so that the
battery can be recharged (see
section “Charging the battery”).

English

29

Changing the transmission channel
To avoid interference caused by the

simultaneous operation of several
transmitters, select a different channel
on each transmitter. Several
switchable transmission channels are
available (C
Due to the required approval two

English

HANNEL).

channels are selectable:
Positions 1 or 3 = channel 1 Position 2 = channel 2

Turning the automatic compression system on
Use the COMP switch (compression) at the rear of the transmitter to turn the

automatic compression system on. This system reproduces soft
passages louder and decreases loud sounds.
Use the MO/ST switch to choose between mono and stereo transmission.
For mono TVs and when using the MKE 800 TV microphone, the switch must
be set to mono (MO).

30

Adjusting the receiver channel
First turn on the transmitter (see section

“Where to place the transmitter”). Then put
on the stethoset receiver - as soon as the
receiver is put on it automatically tunes
itself to the first strong signal found
(normally the transmitter frequency). If, for
some reason, the selected channel is not the
correct one (e.g. because of interference or
another nearby system), press the T

UNE

button at the rear of the receiver until you
can hear the audio signal loud and clear. If
you decide to change the transmitter
channel, the frequency search tuning
must be re-started by pressing the T

UNE

button on the receiver again (see section
“Changing the transmission channel”).

English

31

Charging the battery
Place the receiver into the transmitter’s

charging compartment, with the operating
control at the front. The left LED on the
transmitter must light up.

Charge the battery for 24 hours before you use
it for the first time. The normal charging time

English

is 4-5 hours. A fully charged battery has an
operating time of approx. 4 hours.

Always store the receiver on the
transmitter to ensure that it is fully charged.
The transmitter automatically switches to trickle charging so that the
battery cannot be overcharged. The receiver can remain in the charging
compartment even when the battery has been fully charged.

32

Additional information
The audio transmission technology used with this unit is basically that of a

radio. According to today’s scientific knowledge, the radio waves
emitted by this unit are not harmful to humans or animals.

Varnish or furniture polish may degrade the rubber feet of the transmitter.
Place the transmitter on a nonslip pad to avoid potential staining of
furniture.

Delivery includes a pair of replacement ear pads. If necessary, remove the
old ear pads and slide on the new ones.

Use a soft cloth for cleaning the units. Do not use abrasive cleaners.

English

33

WARNING: Volume up? - No!

When people use headphones, they tend to choose a higher
volume than with loudspeakers. However, if your hearing has
deteriorated and you need to rely on an assitive listening
system, please avoid listening at high volume levels for a long
time. Please protect your hearing.

English

34

Accessories
Only use original Sennheiser spare parts and accessories.

BA 151 rechargeable battery
By using a spare battery, you can use the stethoset receiver for more than
four hours of continuous operation. Always store the spare battery in the
small charging compartment at the right of the transmitter. The right LED on
the transmitter lights up green to show charging is taking place. When
charging a battery in the small charging compartment, the charging time is
10-12 hours.

English

A battery has a service life of 1-2 years and should be replaced if the
operating time decreases.

Additional information for hearing aid acousticians
Adjusting the earbow pressure

Loosen the screw at the rear of the stethoset receiver.
Move the screw in the long hole to the desired position
(continuously adjustable).
1 = Low earbow pressure
2 = High earbow pressure
Tighten the screw.

Adjustments for hearing disabilities
Turn the operating control fully counterclockwise (0). Remove
the operating control by carefully lifting it over the "guide
notch" on the inside. Use the 4 potentiometers on the circuit
board to individually adjust the max. volume and the bass
response for the left and right headphone system.
