Preparing the units for use
Transmitter and receiver have been adapted by your technical expert to suit
your individual applications.
Transporting the transmitter and receiver
In addition to the EZB 2015 system case offering room to store all compo-
nents of the system, delivery also includes a transport case. This is suitable
for the day-to-day transport of a transmitter and a receiver and of two
replacement battery packs.
Push the transmitter and the receiver into the transport holding device as
shown on the left. The units fit snugly in the case preventing damage dur-
ing transport. It is possible to store the battery packs in the front pocket of
the transport case, as well as in the transport holding device.
Inserting the battery pack/batteries
(transmitter and receiver)
For powering the units, we recommend using the supplied BA 2015 battery
pack. The battery pack can be recharged in the L 2015 charger while
remaining in the transmitter or receiver (see operating manual of the
charger). If no power supply is available for recharging the battery pack,
you can alternatively use 1.5 V AA size batteries.
Press the two unlocking buttons
and open the battery compartment
cover
.
Insert the battery pack or the batteries as shown on the left. Please
observe correct polarity when inserting the battery pack or the batte-
ries.

How to properly use the battery pack or the batteries
For battery pack operation, only use the BA 2015 battery pack in order to
ensure optimum operational reliability. Batteries and rechargeable battery
cells have different discharging curves. Transmitter and receiver are able to
identify the BA 2015 battery pack and to use it to full capacity. They also
adapt the battery status display according to the type of power supply used
(batteries or battery pack). Individual rechargeable battery cells will not be
identified as battery packs.
After use (e.g. during the night), charge the BA 2015 battery pack of
the transmitter or receiver in the L 2015 charger. The maximum char-
ging time is 2.5 hours, at which time the unit then switches to trickle
charging.
If you do not use the transmitter or receiver for extended periods of
time (e.g. while you are on holiday), remove the battery pack or the
batteries. After three months at the latest, the battery packs will need
a refresh charge in the L 2015 charger. This prevents damage to the
battery pack due to self-discharge.
Connecting sound sources to the transmitter
Connecting the microphones to the transmitter
In addition to the supplied MKE 2015-2 clip-on microphone, a plug-on
microphone (MKE 2015-0) and a headset microphone (ME 2015-H) are
available as optional accessories. DC powering of these condenser micro-
phones is via the microphone input.
Connect the 2.5 mm jack plug of the microphone or the microphone
cable to the transmitter’s 2.5 mm jack socket (MIC)
.
Via the operating menu, adjust the sensitivity of the microphone input
(see “Adjusting the microphone sensitivity“ on page 82).
69
Attaching and positioning the microphones
The MKE 2015-2 clip-on microphone (supplied) and the MKE 2015-0 plug-
on microphone (optional accessory) are omni-directional and pick up sound
equally from all directions. They are the best choice if movements of the
speaker’s head have to be compensated for. However, they should be
attached as close as possible to the sound source.
Use the microphone clip
to attach the MKE 2015-2 clip-on microphone to
clothing (e.g. tie, lapel) at a maximum distance of 9.8 inches from your
mouth.
When using the MKE 2015-0 plug-on microphone, wear the transmitter
around your neck using the EZG 2015 pouch with neck strap. Adjust the
length of the neck strap so that the distance between the microphone and
your mouth is 9.8 inches at the most.
You can use the MKE 2015-0 plug-on microphone to transmit the speech of
several persons at a time with only one transmitter. Put the transmitter
with the plug-on microphone on the table in front of the speaker. The per-
son speaking should keep a distance of approx. 9.8 inches to the micro-
phone.
The ME 2015-H headset microphone (optional accessory) has a super-car-
dioid pick-up pattern.
Adjust the ME 2015-H headset microphone so that a comfortable and
secure fit is ensured.
Position the microphone of the headset at the corner of your mouth.
Make sure that the sound inlet is directed towards your mouth. The
sound inlet is marked with a little dot.

card of a computer to the line input of the transmitter.
Connect the 3.5 mm jack plug of the connecting cable to the transmit-
ter’s 3.5 mm jack socket (LINE)
.
Via the operating menu, adjust the sensitivity of the line input (see
“Adjusting the sensitivity of the line input“ on page 82).
Note:
If the transmitter is preset so that the line input is switched off, the dis-
play for line level is not shown on the display panel.
Connecting the receiver to hearing aids or headphones
Connecting the receiver to hearing aids with direct audio input
Connect a hearing aid with direct audio input to the receiver’s 2.5 mm
jack socket (LOW)
. Suitable connecting cables (see “System variants
and accessories“ on page 103) are available from your Sennheiser dea-
ler.
Connecting the receiver to a hearing aid without audio input
(hearing aid must have Telecoil)
Connect the EZT 2015 induction neck loop or the EZI 120 induction
couplers for hearing aids without audio input to the receiver’s 3.5 mm
jack socket (HI)
. Suitable connecting cables for the induction coup-
lers (see “System variants and accessories“ on page 103) are available
from your Sennheiser dealer.
Connecting the headphones
You must only connect headphones with a stereo jack plug and a minimum
impedance of 32
Ω
to the receiver (see “Connector assignment“ on
page 102).

Adjustment tips for the operating menu of the
transmitter
Adjusting the microphone sensitivity
SENSIT (MIC)
Via the “
SENSIT
(MIC)” menu, you can adjust the sensitivity of the con-
nected microphone in 32 steps. The microphone sensitivity is correct
adjusted when the display for microphone level (MIC)
shows full deflec-
tion only when you speak very loudly. The yellow LED
should only light
up briefly.
Note:
For monitoring the adjusted microphone sensitivity, the display for
microphone level (MIC)
is always indicated – even when the micro-
phone is muted.
Adjusting the sensitivity of the line input
SENSIT (LINE)
Via the “
SENSIT
(LINE)” menu, you can adjust the sensitivity of the line
input in 32 steps.
The input sensitivity is adjusted too high when loud passages cause over-
modulation in the transmission link. In this case, the yellow LED
will light
up for longer periods of time. If, on the other hand, the sensitivity is
adjusted too low, the transmission link will be undermodulated, which
would result in a signal with high background noise.
The sensitivity is correctly adjusted when the display for line level (LINE)
shows full deflection only during the loudest passages.
Note:
If the sensitivity of the line input is set to “OFF”, the display for line level
(LINE)
is not shown on the display panel.

The system’s range depends to a large extent on location and can be up to 164 feet. There should be
a “free line of sight” between transmitting and receiving antenna.
... for multi-channel operation
y
For multi-channel operation, you can only use the channels in a channel bank. Each of the channel
banks “1” to “8” accommodates factory-preset frequencies which are intermodulation-free. For alter-
native frequency combinations, please refer to the enclosed frequency table. The freely selectable fre-
quencies can be selected via the “
TUNE
” menu and can be stored in the channel bank “U”.
y
When using several transmitters simultaneously, interference can be avoided by maintaining a mini-
mum distance of 7.8 inches between two transmitters.
y
For multi-channel applications, use special accessories (see “System variants and accessories“ on
page 103).
Care and maintenance
y
Use a slightly damp cloth to clean the units from time to time.
Note:
Do not use any cleansing agents or solvents.
y
If you do not use the transmitter or receiver for extended periods of time (e.g. while you are on holi-
day), remove the battery pack or the batteries. After three month, the battery packs will need a refresh
charge in the L 2015 charger. This prevents damage to the battery pack due to self-discharge.
