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).  
y Use the system with care and set it up in a clean, dust-free  
environment.  
y 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 furniture.  
y This system allows you to set higher volumes than  
conventional stethoset systems. This can cause hearing  
damage in persons with healthy hearing and especially in  
children.  
y Please observe the safety instructions for Lithium-Ion  
rechargeable batteries on the enclosed leaflet.  
Intended use of the system  
Intended use includes that:  
y you have read these instructions, especially the chapter  
“Safety instructions”.  
y you are using the system within the operating conditions as  
described in these instructions.  
Improper use  
Improper use means use of the system other than as described  
in these instructions or under operating conditions which differ  
from those described in these instructions.

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.

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.  
Connecting the transmitter to the sound source

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 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.

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 to adjust the volume to a sufficient  
and comfortable level.  
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 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 to re-start transmitter search  
tuning (see previous section).

Adjusting the balance  
The RS 4200 features a balance control for right/left volume  
adjustment.  
̈ Use the balance control to adjust the volume so that you  
hear equally well with both ears.  
Enhancing speech intelligibility  
The button allows you to enhance speech intelligibility.  
̈ If the speech is barely intelligible, press the button . The  
button 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.
