Wireless RF Transmission technology
With this RF stethoset receiver system you can move around freely in the home or outside in
the garden without the constrictions of a cable! The RS 2400 will transmit the stereo sound
signal from your TV set to the stethoset receiver.
It is not necessary that transmitter and stethoset receiver are in a direct line of sight. With an
unobstructed RF link, the distance between transmitter and receiver can be up to 100 m.
Transmission will remain clear and intelligible.
Walls and ceilings impede the propagation of radio waves and the range will decrease. Major
obstacles for radio waves are metal parts as e.g. in concrete constructions or wall coverings, as
they reflect radio waves before these reach the receiver.
One transmitter can supply several
receivers.

Where to place the transmitter
Choose a suitable place near your TV set.
Attention!
Some furniture surfaces have been treated with varnish, polish or synthetics which might
cause stains when they come into contact with other synthetics. Despite a thorough testing of
the synthetics used by us, we cannot rule out the possibility of discolouration, since we don’t
know your furniture. You should therefore always place the transmitter on a non-slip pad.
Putting the transmitter into operation
왘 Use the supplied cable to connect socket on the transmitter
to the headphone socket of your sound source. The cable is
fitted with a 3.5 mm jack plug suitable for most headphone
sockets. For connection to 1/4" (6.3 mm) headphone sockets,
use the supplied adaptor.
왘 Connect the plug-in mains unit to socket on the transmitter
and plug the mains unit into a wall socket.
Antenna
The wire antenna is an integral part of the transmitter. For best
transmission the antenna should be vertical. You can therefore
왘 leave the wire antenna dangling in a vertical position down
behind the transmitter or
왘 (the better option) slide the supplied plastic tube over the
antenna and snap it into the clamp at the back of the transmitter.
Make sure that there are no metal objects such as shelf bars or
lamp stands in parallel with the antenna. Do not place the transmitter on your TV set as it might interfere with the transmitter.
Test where exactly in the room the transmitter works best.

RS 2400_512759_0106_Sp6.book Seite 18 Mittwoch, 15. Februar 2006 8:34 08
Automatic on/off switching
The transmitter features a convenient automatic on/off function. When an audio signal reaches the transmitter, it is switched on and the LED at the front of the transmitter lights up
green. The LED also indicates that an accupack is being recharged. When a stethoset receiver or an accupack is inserted into a charging compartment, the LED lights up red.
Green LED = Transmitter ON
Yellow LED = Transmitter ON, Accupack recharging
Red LED
= Accupack recharging
LED not lit = Transmitter OFF
If there is no audio signal for about 3 minutes, the transmitter automatically switches off. The
transmitter is now in stand-by mode, its power consumption is very low so that it can remain
connected to the mains.
Important
왘 The transmitter’s charging function is independent of the automatic on/off function. Accupacks can always be recharged when the transmitter is connected to the mains.
왘 When you are not going to use the transmitter for some time (e.g. when you are on holiday),
you should unplug the mains unit and take the stethoset receiver and the accupack out of
their respective charging compartments.
Adjustments on your TV set
왘 Please refer to the instruction manual of your TV set to find out whether the volume control
also adjusts the headphone output or whether this output has a separate volume control.
You will also find instructions on how to switch off the main loudspeakers.
18
RS 2400_512759_0106_Sp6.book Seite 19 Mittwoch, 15. Februar 2006 8:34 08
Optimum modulation level of the transmitter
왘 First, set the volume of your TV set to a medium value.
왘 The TR 2400 transmitters is fitted with an automatic modulation control which prevents
overmodulation of the transmitter. The LED at the front of the transmitter indicates
optimum modulation. Now adjust the volume on your TV set such that the LED blinks in
time with the speech, this indicates the correct transmission level.
Putting the receiver into operation
Charge the accupack for 24 hours before you use it for the first time!
왘 Take your stethoset receiver out of the charging compartment on the transmitter.
왘 Have you charged the accupack separately from the stethoset
receiver? Then insert the accupack into compartment in the
receiver.
Switching on the receiver
Use control to switch on the receiver and adjust the volume.
Adjusting the receiver channel
Transmitter and receiver have to operate on the same frequency:
왘 Put the transmitter and the receiver into operation as described
above. Switch on the TV set! If possible, switch off its loudspeakers.
왘 Use switch on the transmitter to select a transmission
channel.
19
RS 2400_512759_0106_Sp6.book Seite 20 Mittwoch, 15. Februar 2006 8:34 08
왘 Set the volume control on the receiver to a medium value (position 3–4).
왘 Slowly turn control (“TUNE”) on the stethoset receiver until you can hear the audio signal
loud and clear. The receiver’s AFC (Automatic Frequency Control) circuitry stabilises your
adjustment.
Transmitter and receiver are now operating on the same frequency.
Simultaneous operation of several systems
Your neighbour also likes listening with radio headphones? No problem! With switch , you
simply select a different transmission channel on each transmitter. Then set the stethoset
receivers to the respective frequencies (with control , as described above). Observe a minimum distance of 2 m between two transmitters.
Due to the required approval two channels are selectable:
Positions 1 or 3 = channel 1
Position 2
= channel 2
20
RS 2400_512759_0106_Sp6.book Seite 21 Mittwoch, 15. Februar 2006 8:34 08
Important
왘 Only use the transmitter with a suitable Sennheiser mains unit. Always disconnect the mains
connector when you wish to change connections or move the device to a different place.
왘 Never open electronic devices! This must only be done by authorised personnel and is all the
more valid for repairs on current-carrying units.
왘 Keep the system away from cental heating radiatiors and electric heaters. Never expose it to
direct sunlight.
왘 Use the system in dry rooms only. Transmitter and plug-in mains unit should always remain
indoors. You can use the stethoset receiver outside if the weather is dry.
왘 Use a damp cloth for cleaning the transmitter and the stethoset receiver. Do not use any solvents. For reasons of hygiene, the ear-cushions can be cleaned with soapy water. We recommend, however, to simply replace them (inexpensive replacement ear-cushions are available
as accessories).
왘 Vanish or furniture polish may degrade the rubber feet of the transmitter. Place the transmitter on a nonslip pad to avoid potential staining of furniture.
Volume up? - no!
When people use headphones, they tend to choose a higher volume than with loudspeakers.
Listening at high volume levels for a long time can lead to permanent hearing defects. Please
protect your hearing, Sennheiser headphones also sound exceptionally good at low volumes.
21
RS 2400_512759_0106_Sp6.book Seite 22 Mittwoch, 15. Februar 2006 8:34 08
What to do if...
... the volume is up but you
cannot hear anything:
왘There is no audio signal available. Check the transmitter
connection. Is the volume at the headphone socket
of your sound source sufficient?
왘Are you still within the transmitter’s range?
왘Is the receiver on the same frequency as the
transmitter?
... the sound is distorted:
왘The receiver accupack has gone flat, please
recharge it immediately.
왘The volume on the receiver is adjusted too high.
Reduce the volume.
... the sound is slightly noisy:
왘You are about to leave the transmitter’s maximum
range. Soon transmission will be interrupted
completely.
왘The transmitter’s modulation level is too low.
Increase the volume on your sound source.
... you can hear twittering and
왘Two transmitters are interfering!
chirping, and the sound is “squeezed”: Choose a different transmission channel.
... the transmitter switches off
during operation:
22
왘The volume on your TV set is adjusted too low. Adjust
the volume on the TV set such that the LED on the
transmitter blinks occasionally.

Accessories
왘 BA 151
Rechargeable accupack as a spare, for use when the
supplied accupack is being recharged.
왘 L 151-2
Charger for recharging two BA 151 accupacks
(recommended when more than two stethoset receivers
are used with one transmitter).
왘 RR 2400
Additional stethoset receiver
Rechargeable accupacks have a "charging cycle"
The charging time of the batteries depends on how long you have used your stethoset
receiver. General rule:
Operating Time x 3 = charging time
Example:
listening: 1hr
recharging: 3 hrs
listening: 2 hrs
recharging 6 hrs
listending: 3 hrs
recharging: 9 hrs
23
RS 2400_512759_0106_Sp6.book Seite 24 Mittwoch, 15. Februar 2006 8:34 08
Recharging the BA 151 accupack
Do not let the accupacks become completely flat. If you do, they will be exhausted and cannot
be recharged (“total discharge”). This happens e.g. when flat accupacks remain uncharged for
some time. Please observe the three following rules:
왘 If you notice that the accupack is going flat, switch off the stethoset receiver and recharge
the accupack immediately. If you have a spare accupack you can use it in the meantime.
왘 Immediately recharge the accupack after each use, no matter whether it is fully or only
partly discharged.
왘 Charge the accupack for 24 hours before you use it for the first time!
Please note: With both charging possibilities, the accupacks are also recharged when the
transmitter is switched off but remains connected to the mains.
Environment and health
Devices powered by rechargeable batteries are environmentally friendly. This energy source
can be recharged many times. Conventional batteries, on the other hand, must be disposed of
as special waste after they have been used just once. If an accupack should be defective or has
been damaged due to total discharge, it is then recycled – the dealer who sold it to you will
take it back and will also supply you with a new, original Sennheiser accupack. (Recycling
methods differ in different countries.)
According to today’s scientific knowledge, the radio waves emitted by this device are by no
means harmful.
