Selecting a hearing profile for sound enhancement
The hearing profiles allow you to alter the sound of the audio signal
in order to improve the speech intelligibility and to adjust the sound
to suit your preferences. The profiles are used to specifically change
certain frequency ranges by e.g. boosting or attenuating low-fre
quency or high-frequency tones.
All hearing profiles feature a compression function which compensates for volume differences by boosting the volume of quiet passages and reducing the volume of loud passages if necessary.
The balance setting is saved on the stethoset receiver. If you
are using several receivers with a transmitter, the respective
receivers are optimally adjusted to match the personal hearing preferences of the users (e.g. you and your partner).
Please note that the personal hearing preferences can only be
adjusted when only stethoset receiver is connected to the
transmitter.

Activating/deactivating the speech intelligibility function
When speech is mixed with annoying background noise, speech
may be difficult to understand.
The speech intelligibility function automatically detects and
reduces annoying background noise. The audio signal is perma
nently analyzed and adjusted accordingly so speech is foregrounded and easier to understand.

Using additional functions
The following additional functions are not required for normal use
of the wireless headphone system. You can, however, extend the
potential use of the system and adjust some of the functions to
your individual needs.
Pairing one or several stethoset receivers with the transmitter
The stethoset receiver and the transmitter of your wireless headphone system are factory pre-paired. The following steps are only
necessary if you want to pair additional stethoset receivers with the
transmitter.
You can simultaneously use up to 4 paired stethoset receivers with
your transmitter. All other paired and switched-on receivers cannot
connect to the transmitter.
If more than one stethoset receiver is connected to the transmitter, the remaining operating time/charge status and the
hearing profile cannot be displayed. In addition, the balance
and a hearing profile cannot be adjusted. These functions can
only be used/adjusted when only one stethoset receiver is
connected to the transmitter.
Option A (contact pairing)
왘 Place the stethoset receiver into the transmitter’s charging com-
partment.
The stethoset receiver is paired with the transmitter.
Option B (proximity pairing)

Leaving the range of the transmitter
The range of the transmitter largely depends on environmental conditions such as wall thickness, wall composition etc. If the headphones leave the range of the transmitter, the audio first cuts out
occasionally until it finally cuts out completely. You hear alerts in
the stethoset receiver.
If you re-enter the transmission range within 5 minutes, the connection is automatically re-established.
If you spend more than 5 minutes outside the transmission range,
the stethoset receiver switches off automatically.
