3. Preparing the hearing instrument
for FM use
Fitting example: Phonak CORE* hearing instrument
Drag and drop FM program into manual programs or EasyFM:
3.1 Program selection
Hearing instruments can be divided into two types with respect to the
external audio input: DPAI Yes and DPAI No. DPAI stands for Designated
Programmable Audio Input.
DPAI No
FM is usually directly wired with the microphone in the normal listening
program. Attenuation of the hearing instrument microphones depends
on the impedance of the external device. Selection between “FM+M”
and “FM only” takes place on the receiver.
SP
DPAI Yes
On these hearing instruments, the audio input has its own Designated
Programmable Audio Input and the FM program is selected via the
program structure of the hearing instrument. Please activate the
instrument’s FM+M and/or FM only program. The FM+M program is
recommended for most listening situations.
Most Phonak HIs offer the EasyFM feature. If this is enabled, the HI
automatically switches to FM mode a few seconds after a signal (e.g.
voice or music) has been broadcast by the FM transmitter. The reaction
time of the EasyFM feature ranges up to several seconds depending on
the hearing instrument and the signal intensity. The HI automatically
switches back to the default listening program after approximately one
minute, when no signal has been broadcasted by the transmitter.
*Current CORE hearing instruments from Phonak include: Exélia, Versata, Certéna, Naída, Nios and Milo.
3.2 Attaching the audio shoe

4. Fitting MLxi
MLxi can also be connected
to the iCom
A separate brochure describes the optimal
FM solution for different use cases,
including extensive information about
the combination of MLxi and iCom.
4.1 AutoConnect
MLxi/MLxi Baha features AutoConnect. This feature measures the input
impedance of the hearing instrument and automatically provides an
FM Advantage of 10 dB, regardless of whether the hearing instrument
is DPAI Yes or DPAI No. The fitter simply connects the MLxi/MLxi Baha
to the audio shoe attached to the hearing instrument.
Other hearing instruments
Attach audio shoe according to the user
guide of the hearing instrument.
Please note these important points:
ß Make sure your hearing instrument is switched on when you connect
the MLxi/MLxi Baha.
ß The first time you connect MLxi/MLxi Baha to a hearing instrument,
it may take up to one minute until MLxi/MLxi Baha has automatically
corrected the gain to provide 10 dB FM Advantage.
ß At every startup, AutoConnect plays a beep to measure the impedance
of the hearing instrument. This measuring beep may be audible.

4.2 Advanced fitting of MLxi using FM SuccessWare
Baha
MLxi Baha can be plugged directly into
most Baha processors.
The extended mode of FM SuccessWare enables you to fine-tune some
parameters of the MLxi according to the needs of your customers.
Make sure the circular MLxi Baha pin
matches the marked hole of the Baha
processor.

Fitting Guide
MLxi and MLxi Baha
Associated hearing instrument
You can select the hearing instrument on which the MLxi will be used.
This selection has no influence on the setting unless you select a cochlear
implant model. In all other cases the “AutoConnect” feature corrects
for any impedance mismatch. When the MLxi is used on a cochlear
implant speech processor, it is strongly recommended to select the
specific speech processor from the drop-down list (also refer to page 6).
Beep type
MLxi/MLxi Baha plays a confirmation beep at start up or when the
system synchronizes with a transmitter. You can change the type of
beep tone using the drop-down menu.
Startup channel
There are two choices:
a) “Default”: At every startup, the MLxi/MLxi Baha is ready to receive
the signal on the default channel chosen in the “Select channels”
section of FM SucccessWare. Phonak recommends using this option
if your client has his own transmitter which always operates on the
same channel. Select as default channel in the MLxi/MLxi Baha the
same channel the transmitter transmits on.
b) “Last used”: At startup, the MLxi/MLxi Baha will receive the signal
on the channel to which it was last synchronized (the same channel
MLxi/MLxi Baha was using before switch off). Phonak recommends
using this option if the client receives the signal on different channels
during the day (e.g. in school).
V1.00/2010-03/visu’l © Phonak AG/All rights reserved/page 5/11
Push button
The push button of MLxi/MLxi Baha is by default disabled. If you enable
the push button, it will have different functions depending on whether
the hearing instrument is DPAI Yes or DPAI No. For all types of
hearing instruments, pressing the button for two seconds switches the
MLxi/MLxi Baha on or off respectively.
If…
ß the hearing instrument is DPAI No and
ß the push button is enabled and
ß the MLxi/MLxi Baha is switched on and
ß a Classic FM transmitter is used, a short press on the push button will
toggle between “FM+M” and “FM only”. For both “FM+M” and “FM only”
a beep may be audible. The beep is the same for “FM+M” and ‘FM only”.
With push button enabled the MLxi/MLxi Baha will be in off
mode by default. The MLxi/MLxi Baha must be switched on,
by pressing for two seconds on the push button, after it has
been disconnected from the hearing instrument or the hearing
instrument was switched off.
Personal preference
The MLxi/MLxi Baha comes with a personal preference of 0 dB, which
corresponds to a 10 dB FM Advantage when connected to a hearing
instrument. The 10 dB FM Advantage is automatically checked/ adjusted
every time MLxi starts. Usually, the 10 dB FM Advantage is well
accepted by clients. However it is possible to reduce or increase the
personal preference of the FM Advatage on MLxi/MLxi Baha. The
range for this change is 8 dB louder or softer respectively and can be
adjusted in 2 dB steps.
Note:
For MLxi Baha it is possible to adjust the gain for “FM+M” and
“FM only” separately.
4.3 Fitting MLxi/MLxi Baha using inspiro
With Dynamic FM inspiro it is possible to change some MLxi/MLxi Baha
settings. Please select “Receiver options” in the inspiro menu.
ß Push button activation/deactivation – use the function “lock push button”
ß Change of personal preference – use the function “Set FM volume”
ß Activation/Deactivation of the beep tone – use the function “Set beep tone”
Note:
The menu “receiver options” can only be accessed in the extended
mode of the inspiro menu.
5. Additional fitting information
5.1 Toggling between “FM+M” and “FM only” when
MLxi/MLxi Baha is used in combination with a
Classic FM transmitter
MLxi/MLxi Baha does not have a switch to select between “Off”, “FM
only” and “FM+M”. The customer does not need such a switch when a
Dynamic FM transmitter (inspiro, DynaMic, SmartLink+, ZoomLink+ or
EasyLink+) is used.
However, MLxi can also be used with the following Classic FM transmitters:
Campus SX, EasyLink, ZoomLink, SmartLink and Classic FM inspiro. For
these combinations, there is no Adaptive FM Advantage feature, which
automatically adjusts the FM Advantage in noisy environments, and
no Voice Activity Detection, which automatically reduces the FM level
when no voice is present at the transmitter microphone.
In those cases the user needs to have the chance to select between
“Off”, “FM only” and “FM+M”, as with a Classic FM receiver. For DPAI
Yes hearing instruments this selection takes place by toggling between
different HI programs such as “no FM”, “FM only” and “FM+M”. For
DPAI No hearing instruments this selection takes place on the receiver.

(program change is confirmed by a short beep)
5.2 Fitting MLxi to a cochlear implant speech processor
The AutoConnect feature of MLxi precisely measures the impedance of
the audio input and automatically sets the output to match the input.
Due to the special design of audio inputs of cochlear implants, AutoConnect may not find the correct matching parameters. Therefore, it is
recommended to program the MLxi using FM SuccessWare by selecting
the specific CI speech processor from the drop down list:
The various combinations available look like this:

Programming MLxi for a specific processor disables AutoConnect and
the output parameters of MLxi are optimized for the selected processor.
If you do not program the MLxi using FM SuccessWare, the user may
experience the following:
ß An audible tone burst every startup (indicating the AutoConnect
measurement)
ß Incorrect Freedom BW and 3G speech processor FM levels
ß Incorrect Harmony/Auria and Freedom Bodyworn monitoring results
