Safety instructions

Never open the transmitter nor the receiver, otherwise you can be
injured and the warranty becomes null and void.

Attention: Do not wear the headphones in situations

which require special attention (e.g. in traffic or when

Attention: Listening at high volume levels can lead to

Wall mounting

The transmitter is prepared for wall mounting. The required
mounting hardware (screws and plugs) is not included in the
delivery.

12

Connecting the transmitter (Fig. 1)

Establish the necessary connections (mains unit, audio connecting
cable).

Removing the ear cushions (Fig. 2 and 3)

The ear cushions are secured to the earcups by means of a quarter
turn fastener. To remove an ear cushion, turn it in the dire ction of
the arrow until you overcome a slight resistance and lift it off the
earcup.

Inserting the rechargeable batteries (Fig. 4)

Remove the left ear cushion (Fig. 2 and 3).
Insert the rechargeable batteries.

Attention: Observe correct polarity when insert ing the b at teries!

Charging the rechargeable batteries

For charging the batteries, place the headphones on the charging
cradle of the transmitter. (The headphones automatically turn off
during charging.) The red LED “CHARGE” lights up during the
charging process. If the batteries are fully charged, the transmitter
automatically switches to trickle charging and the red LED “CHARGE”
flashes slowly.

Charge the batteries for at least 16 hours prior to first time use.
Subsequent charging time is about the same time as the previous
operating time.

Always store the headphones on the transmitter to ensure that they
are fully charged when they are needed. The intelligent battery
charging technology prevents overcharging. If you do not use the
head-phones for extended periods of time, please remove the
batteries and disconnect the transmitter’s mains unit from the
mains.

Nearly discharged batteries will significantly reduce the sound
quality. Approx. 10 minutes before the batteries are completely
discharged, an acoustic warning signal is produced (two long beeps,
see table on page 16).

ENGLISH

13

Turning the transmitter on and off (Fig. 5)

Turn on the sound source. This automatically activates the
transmitter and the green LED “ON/OFF” lights up. If the sound
source is turned off, the transmitter is automatically deactivated
after approx. 3 minutes (the LED “ON/OFF” goes off).

Note: The automatic level control only functions if the volume of the

sound source is sufficient.

ENGLISH

Turning the headphones on and off (ON/OFF, Fig. 5)

Move the “ON/OFF” switch on the headphones to the position “ON”.
The headphones then start the transmitter search-tuning.

Adjusting the volume (VOLUME, Fig. 6)

Use the “VOLUME” control to adjust the volume on the headphones.

Adjusting the balance (BALANCE, Fig. 6)

Use the “BALANCE” control to adjust the volume of the right and left
channels. There is a click-stop in the center position.

Auto-tuning – automatic transmitter search-tuning with

memory function

Note: The transmitter must be activated (green LED “ON/OFF” lit)

and the headphones must be turned on.
By pressing the TUNE button or after turn-on, the headphones start

scanning the whole frequency range for a transmitter signal. If a
transmitter signal is found, the transmitter search-tuning stops and
the audio transmission starts.

If, for some reason, the signal found is not the correct one (e.g. from
another nearby system), press the TUNE button again and the
transmitter search-tuning is continued. When turning on the head­phones, they automatically start the transmitter search-tuning on
the last selected channel.

If no transmitter signal is received for an extended period of time
(e.g. the range is exceeded or the transmitter is deactivated), six
short beeps are produced. After approx. 10 minutes, the

(TUNE, Abb. 7)

headphones automatically turn off. By pressing the TUNE button,
the headphones can be turned on again.

Self-learning automatic level control with memory
function

The transmitter is equipped with an automatic level control which
ensures that the headphones always receive an optimum signal. The
level is continuously adjusted during operation and remains stored
as long as the transmitter is connected to the mains.

Under-modulation (audio signal too low)

With under-modulation, the yellow LED “INPUT LEVEL” flashes
slowly. If this happens, gradually increase the volume of the sound
source. If the audio signal remains too weak, an optimum trans­mission is not possible. It could be that the transmitter is
deactivated after some time.

Over-modulation (audio signal too high)

With over-modulation, the yellow LED “INPUT LEVEL” flashes rapidl y.
If this happens, gradually reduce the volume of the sound source.

Dynamic compression system (Fig. 8)

The RS 140 system is equipped with a switchable dynamic
compression system. This system reproduces soft passages louder
and decreases loud sounds. To activate t he dynamic compression
system, move the slide switch “COMPRESSION” on the transmitter to
the right. The yellow LED “COMPRESSION” lights up. If the LED
flashes slowly, gradually increase the volume of the sound source
(see “Under-modulation”).

ENGLISH

Automatic noise reduction

In addition, the transmitter features a “Noise Gate” function, which
reduces hissing noise when no audio signal is transmitted (e.g.
during pauses).

Turning the acoustic signals (beeps) on and off

The acoustic signals of the headphones can be turned on or off as
follows:

y Turn the headphones on.
y Press the TUNE button for 5 seconds.
y Turn the headphones off.
y If the acoustic signals are turned on, the headphones produce a

sequence of beeps at turn-off. If no beeps are produced, the
acoustic signals are now turned off.

If problems occur...

y Check if all jack plugs are connected correctly.
y Make sure that the batteries are charged.
y Check if the batteries are inserted correctly and that the polarity

is correct.

y Check if the headphones and sound source are turned on and

that the volume of the headphnes and sound source is sufficient.

y Move closer to the transmitter.
y Choose a different channel on the transmitter.
y Press the TUNE button again.
y Reset the system:

Remove the rechargeable batteries from the headphones and –
at the same time – interrupt the power supply of the transmitter
for at least 30 seconds.

y Some electronic devices (e.g. televisions) can cause interference,

which can be eliminated by increasing the distance between the

transmitter and the interference source.
y Try to operate the transmitter with a different sound source.
Should the problem persist, please contact your authorized dealer

for assistance.
