Safety instructions
y Please read these instructions carefully and completely
before using the system.
y Make these instructions easily accessible to all users at all
times. Always include these instructions when passing the
system on to third parties.
y Do not wear the headphones in situations which require
special attention (e.g. when performing skilled jobs).
y Always keep the system dry and do not expose it to extreme
temperatures (ideally 10-35°C).

The RS 4200 stethoset receiver system
The RS 4200 is a wireless radio frequency stethoset receiver
system with which you can adjust the volume of your TV, radio,
personal stereo and other hi-fi equipment to suit your
individual needs. The transmitter has a range of up to 100 m
(depending on outer conditions) which allows you to move
around freely – without the constrictions of cables.
The RS 4200 is particularly easy and intuitive to operate. The
stethoset receiver automatically switches on when you pull the
earbows apart. The volume can be adjusted directly on the
receiver. The speech intelligibility can be enhanced at the press
of a button on the transmitter.
The transmitter has an integrated charging compartment for
storing the receiver and simultaneously charging the receiver’s
rechargeable battery. In addition, a spare rechargeable battery
can be charged in the small charging compartment at the side
of the transmitter.

y
y
y
Do not place the transmitter close to metal objects such as
shelf bars, reinforced concrete walls, etc. as this can
decrease the transmitter’s range.
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.

green: The rechargeable battery is fully charged.
9
Using the system components
Switching the transmitter on
The transmitter automatically switches on when a sufficient
audio signal is present at the headphone socket of your sound
source.
̈ Switch your sound source on. This automatically switches on
the transmitter and the LED ƹ lights up green.
̈ If the transmitter does not switch on, increase the volume of
your sound source.
Note:
If there is no sufficient audio signal for at least 3 minutes, the
transmitter automatically switches off.
Switching the stehoset receiver on
Volume up? - No!
Attention!
When people use headphones, they tend to choose
a higher volume than with loudspeakers. Listening
at high volume levels for long periods can lead to
permanent hearing defects. Please protect your
hearing, Sennheiser headphones also sound
exceptionally good at low volumes.
The stethoset receiver automatically switches on when you pull
the earbows apart and put the receiver on. When you take the
receiver off, it automatically switches off.
̈ Before putting the receiver on, use the volume control ᕡ to
adjust the volume to a low level. This protects your hearing
from damage.
̈ Put the receiver on the correct way round, with the
Sennheiser logo at the front.
10
Adjusting the volume
̈ If the transmitter is connected to a headphones socket of
your sound source:
Adjust the volume of the sound source to a medium level.
This improves the quality of wireless sound transmission.
̈ Use the volume control ᕡ to adjust the volume to a sufficient
and comfortable level.
ᕡ
Automatic transmitter search tuning
̈ Put the receiver on.
The receiver starts searching for a transmitter signal and
automatically tunes itself to the last selected channel. If a
transmitter signal is found, the transmitter search tuning
stops and the receiver produces – depending on the selected
channel – 1, 2 or 3 beeps (see “Meaning of the LEDs and
acoustic signals” on page 13). The audio transmission then
starts.
¿
̈ If the signal found is not the correct one (e.g. from another
nearby system):
Briefly press the TUNE button ᕤ to continue the transmitter
search tuning.
Changing the transmission and receiver channel
If several transmitters are operated simultaneously and are
very close to one another, reception can be subject to
interference (e.g. hissing).
̈ Change the position of the channel selector switch
CHANNEL ² to change the transmission channel.
²
̈ Press the TUNE button ᕤ to re-start transmitter search
tuning (see previous section).
11
Adjusting the balance
The RS 4200 features a balance control for right/left volume
adjustment.
ᕣ
̈ Use the balance control ᕣ to adjust the volume so that you
hear equally well with both ears.
Enhancing speech intelligibility
The button ᕨ allows you to enhance speech intelligibility.
̈ If the speech is barely intelligible, press the button ᕨ. The
button ᕨ is backlit in yellow and speech intelligibility is
enhanced.
Note:
If the speech remains barely intelligible, increase the volume
of your sound source.
Storing and charging the receiver
Do not store your 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
compartment µ as shown on the left, without exerting too
much pressure.
̈ If the receiver is placed correctly into the charging
µ
compartment, the LED Ƹ lights up
red:
The rechargeable battery is being charged.
green: The rechargeable battery is fully charged.
Ƹ
̈ Before you use the rechargeable battery for the first time,
charge it until the LED Ƹ lights up green. This can take a
maximum of 3 hours. With a fully charged battery, the
operating time is approx. 9 hours.
Note:
Always store the receiver in the transmitter’s charging
compartment µ to ensure that it is fully charged. The intel-
ligent battery charging technology prevents overcharging.
When not using the receiver for extended periods of time,
charge the battery regularly every three months.
