Set 820
Thank you for choosing Sennheiser! Over half a century of accumulated

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.

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
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.
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.

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.

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.
After use, the receiver automatically
turns off.

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”).

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
HANNEL).
Due to the required approval two
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).

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”).

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
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.

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.

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.
