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 compen-
sates for volume differences by boosting the volume of quiet pas-
sages and reducing the volume of loud passages if necessary.
Displaying the activated hearing profile
The activated hearing profile is not permanently displayed.
To check the activate hearing profile:
E Switch the stethoset receiver on by putting it on (see page 19).
E Briefly press the
Hearing profile
button on the transmitter.
The currently activated hearing profile is displayed for 10 sec-
onds.
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 hear-
ing 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

Selecting a hearing profile
To select the hearing profile that best suits you, proceed as follows:
1 Switch your audio source on
and select a program where
speech is foregrounded.
2 Put the stethoset receiver on
and make sure that only this
receiver is connected to the
transmitter. Otherwise, a hear-
ing profile cannot be adjusted.
3 Use the L and R buttons on the
transmitter to adjust the bal-
ance (see page 23). This
ensures that each subsequently
selected hearing profile is per-
fectly matched to your left/
right balance setting.
4 Press the
Hearing profile
button on the transmitter
for 2 seconds to select the next
hearing profile.
Press the button again for
2 seconds to switch to the next

5 Test which of the hearing pro-
files (1, 2 or 3) gives you the
best sound quality and helps
you to hear best.
Your individual hearing profile
is adjusted and saved on the
stethoset receiver.
Since your level of hearing impairment may change over time,
we recommend that you repeat the selection of the hearing
profile from time to time.
If you switch to the next hearing profile, the speech intelligi-
bility function is automatically deactivated so that you can
hear the hearing profile unchanged (see page 26).
To prevent accidental adjustment of the hearing profile set-
tings, you can activate the settings protection function (see

Replacing the stethoset receiver’s rechargeable
battery
The BAP 800 rechargeable battery of the stethoset receiver is com-
pactly built into the receiver housing and does not have to be
replaced or removed.
If the operating time of the stethoset receiver decreases drastically
or if a charging error is displayed during charging (see page 16), the
rechargeable battery may be exhausted or defective and has to be
replaced.
Outside the warranty period, the rechargeable batteries may be
replaced or removed by any qualified service center in an appropri-
ate manner. Instructions for qualified service centers on how to
replace or remove the rechargeable batteries are available from
your Sennheiser service partner.
You need suitable tools for replacement. We therefore recommend
to have the rechargeable battery replaced by your Sennheiser ser-
vice partner. To find a Sennheiser service partner in your country,
search at www.sennheiser.com.
CAUTION
Danger of damage to the product!
During the warranty period, the rechargeable batteries must only
be replaced or removed by an authorized Sennheiser service part-
ner, otherwise the warranty will be null and void.
E Contact your Sennheiser service partner if the rechargeable bat-
teries need to be replaced or removed.

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 head-
phone 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.
Option A (contact pairing)
E Place the stethoset receiver into the transmitter’s charging com-
partment.

mono operation.
This setting is saved on the transmitter, independent of the ste-
thoset receiver you are using.

supply unit until it clicks audibly into place.
2 Connect the connector of the power supply unit to the connec-
tion socket of the MCA 800 charging adapter.
3 Plug the power supply unit into the wall socket.
4 Connect the charging adapter to the charging contacts on the
stethoset receiver. The charging adapter is magnetically ori-
ented to the correct position.
The rechargeable battery is being charged. The LED on the
charging adapter lights up red. When the rechargeable battery is
fully charged, the LED lights up green.
If the LED on the charging adapter flashes red and green, a charging
error/battery error has occurred. In this case, disconnect the
charging adapter from the stethoset receiver. More information on
the rechargeable battery can be found on page 28.
WARNING
Interference due to magnetic fields!
The MCA 800 charging adapter generates stronger permanent mag-
netic fields that could cause interference with cardiac pacemakers
and implanted defibrillators (ICDs).
E Do not use the MCA 800 charging adapter when you wear a car-
diac pacemaker, implanted defibrillator or other implant.
You can also use the stethoset receiver during charging.
Please note, however, that the receiver can get slightly warm
during charging. The charge status of the rechargeable bat-
tery is displayed on the transmitter (see page 16).

Leaving the range of the transmitter
The range of the transmitter largely depends on environmental con-
ditions such as wall thickness, wall composition etc. If the head-
phones 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 con-
nection is automatically re-established.
If you spend more than 5 minutes outside the transmission range,
the stethoset receiver switches off automatically.
