Hear now. And, always Cochlear”
Summary
FM systems are designed to improve a recipient's signal-to-
noise ratio (SNR) to allow better hearing in noise. FM systems
are useful when the signal comes from a consistent source. For
example, children may use an FM system in the classroom to
hear the teacher over other classroom sounds. Adults may use
an FM system in business meetings to hear the presenter over
the sound of a projector fan and other ambient noise.
Custom Sound" Suite 3.2 provides a software upgrade to
the Cochlear" Nucleus? CP810 Sound Processor making
it compatible with ear-level Dynamic FM receivers. It also
implements changes that affect how the Cochlear Nucleus
CR110 Remote Assistant can be used.
The Nucleus CP810 Sound Processor can incorporate FM signal
inputs through the following devices:
* an ear-level receiver directly connected to the sound
processor
« an ear-level FM receiver connected to the sound processor
using the Euro Accessory Adaptor
* aneckloop receiver and the sound processor's telecoil, or
* an FM cable connected to a body-worn receiver.
Custom Sound Suite 3.2: Summary of changes
Custom Sound Suite 3.2 provides a software upgrade to the
sound processor making it compatible with ear-level Dynamic FM
receivers such as the Phonak MLxi and ML14i. It also implements
changes that affect how the Cochlear" Nucleus? CR110 Remote
Assistant can be used.
Ear-level FM receivers with Dynamic FM capabilities are supported
only in the CP810 Build Standard C processor. CP810 Build
Standards A and B support Dynamic FM in neckloop receivers. The
build standard of the processor is identified by the last letter in
the serial number. Locate the serial number on the curved inside
edge of the CP810 and read the last letter (e.g. ‘#1010090115377
A’ is a Build Standard A processor).
A message will be provided when programming with Custom
Sound 3.2 if the anticipated battery life of the sound processor is
not sufficient to support FM usage.
ð FM accessory receiver use is not recommended with this MAP due to power
tequtements. The user may experience processor shutdowns, or degraded
performance near the end of battery life when using an FM receiver. To lower MAP
power requirements, reduce maxima, reduce rate or widen pulse width
The LED on a programmed sound processor will indicate when the
user changes between the FM system and microphones.
New sections added to this guide include: Adjusting sensitivity
and mixing levels; What is Dynamic FM?; Considerations prior to
fitting an FM system; Functional testing.

Note: for neckloop receivers, please manually activate the telecoil
ASC+ADRO® (use default Everyday Environment setting and the default sensitivity setting of 12)
PARAMETER JUSTIFICATION
A mixing ratio of 1:1 in a classroom or meeting environment provides a good compromise between FM inputs (teacher or key speaker) and
the sound processor microphone input (other students in the room or other meeting attendees). Other mixing ratios may be used as desired
to reduce audibility of sounds coming directly into the CP810 Sound Processor microphones (e.g. a 2:1 or 3:1 mixing ratio may be used in
situations where the speaker's voice is projected directly into the transmitter microphone such as in a lecture theatre or auditorium. In these
cases, the microphone input is attenuated which places greater emphasis on the FM signal).
Cochlear recommends deactivating Auto Telecoil for children. This is especially true with FM systems because:
* the first sentence spoken by the teacher after a long pause may not be picked up by the FM. (This is because it can take a few seconds for the
auto telecoil to recognise the incoming speech.)
* music is not likely to activate the Auto Telecoil. (This is because the auto telecoil signal may drop out when non-speech like signals are
present.)
ASC is designed to automatically reduce the sound processor's microphone sensitivity to reduce the negative effects of background noise and
is proven to provide optimal performance when using FM. ASC should always be used with FM'.
ADRO actively adjusts individual channel gains. It increases the gains for soft sounds and decreases the gains for high intensity sounds.

Specific recommendations for the use of FM systems with the
EAR-LEVEL
FM RECEIVERS
Cochlear Nucleus CP810 Sound Processor
1. Ear-level FM receivers with and without the Euro Accessory Adaptor
HOW DOES AN EAR-LEVEL FM RECEIVER WORK?
The microphone of the FM transmitter picks up the speaker's voice and
sends it via a specific radio frequency (RF) channel to the FM receiver.
When the transmitter and the receiver are turned on, the wireless
connection is established between the two devices, since most current
devices automatically synchronise to the same channel (this can be done
manually if required). The Euro Accessory Adaptor connects an ear-level
receiver to the CP810 Sound Processor via the accessory socket.
CONNECTING AN EAR-LEVEL DYNAMIC FM RECEIVER
Some ear-level Dynamic FM receivers, such as the Phonak ML14i, connect
directly into the CP810 Sound Processor's accessory socket. Once the
receiver is plugged in, it will automatically turn on. Other ear-level
Dynamic receivers, such as the MLxi require the use of the Euro Accessory
Adaptor to work.
5 Cochlear Update | FM Solutions
CONNECTING AN EAR-LEVEL RECEIVER
Insert the FM receiver into the three pin socket on the Euro Accessory
Adaptor. Insert the Euro Accessory Adaptor into the sound processor’s
accessory socket and switch the FM receiver on (instructions for specific
models follow). The CP810 Sound Processor automatically detects the
Euro Accessory Adaptor and FM receiver. The CP810 Sound Processor
should be programmed with Custom Sound 31 or a later version to ensure
automatic detection of the FM receiver and Euro Accessory Adaptor.
WHAT ARE THE COMMERCIALLY AVAILABLE EAR-LEVEL FM
RECEIVERS FOR THE CP810 SOUND PROCESSOR?
Following is a current list of the commercially available, ear-level FM
receivers that have been validated and meet Cochlear's requirements
for use with the CP810 Sound Processor. This list will be updated with
additional ear-level FM receivers as they meet Cochlear's requirements and
validation testing.
Note: Dynamic ear-level FM receivers are supported only in the CP810
Build Standard C processor. CP810 Build Standards A and B support
Dynamic FM in neckloop receivers (e.g. MyLink+). The build standard of the
processor is identified by the letter after the serial number. Locate the serial
number on the curved inside edge of the CP810 and read the letter (e.g.
'#1010090115377A' is a Build Standard A processor).

2. Neckloop systems
HOW DOES A NECKLOOP FM SYSTEM WORK?
A neckloop is a necklace-size loop of covered wire that includes an FM. The
sound processor's telecoil is used to pick up the electromagnetic field that
the neckloop produces.
The microphone of the FM transmitter picks up the speaker's voice and
sends it via a specific radio frequency (RF) channel to the FM receiver.
The FM neckloop receiver is worn around the neck of someone who has a
sound processor with a telecoil. When the transmitter and the receiver are
turned on, the wireless connection is established between the two devices,
since most current devices automatically synchronise to the same channel
(this can be done manually if required). The sound processor must be in
telecoil mode; Cochlear recommends manual activation, for the reasons
outlined on page 5 of this guide.

3. Body-worn systems
HOW DOES A BODY-WORN FM RECEIVER WORK?
An FM cable connects the CP810 Sound Processor to a commercially
available body-worn FM receiver using the Freedom" Accessory Adaptor.
The Freedom Accessory Adaptor connects the processor end of the FM
cable into the accessory socket of the CP810 Sound Processor.
Body-worn FM receivers are used with an FM transmitter and microphone,
which picks up the speaker's voice. Once the transmitter and the receiver are
turned on, the wireless connection is established between the two devices.

4. Adjusting sensitivity and mixing levels
Sensitivity adjustments on the CP810 Sound Processor act on the
combined signal. This differs from Freedom", where sensitivity acts only
on the sound processor's microphone signal, when using an accessory
input such as an ear-level FM receiver. The advantage of having sensitivity
operate on the combined signal is that it controls the amount of
compression applied to the speaker's voice. Reduced compression means a
clearer sound and better understanding in noise.
Decreasing the sensitivity on the CP810 Sound Processor can reduce the
effect of background noise (such as 'telecoil hum' that may be picked up
when using a neckloop receiver). Background noise can occur in some
environments where the lighting and/or computers create a magnetic field
that interacts with the telecoil.
Note: Autosensitivity™ is automatically applied to the microphone prior to
mixing, and to the mixed signals. This means that the user typically won't
need to adjust the mixing ratio if there is additional background noise.
12 Cochlear Update | FM Solutions
While Freedom users may be accustomed to using sensitivity to adjust the
loudness of the microphone input (effectively changing the mixing ratio),
the appropriate technique for the CP810 Sound Processor is to use the
mixing ratio on the CR110 Remote Assistant to adjust the loudness of the
sound processor's microphone input, relative to the FM signal. The mixing
ratio can only be changed when the remote assistant is in ‘advanced’
mode. If the remote assistant is in ‘simple’ mode, the mixing ratio is fixed
to the value programmed by the clinician when using the Custom Sound
software. The default mixing ratio is 1:1 which means the microphone
input is not attenuated relative to the FM input; a 2:1 and 3:1 mixing ratio
means the microphone input is reduced by 6dB and 9.5dB respectively.
5. What is Dynamic FM?
Dynamic FM automatically varies the gain of the FM receiver with changes
in the ambient noise levels. Traditional FM systems use only fixed gain
settings.
Dynamic FM is a feature introduced by Phonak, using proprietary
technology known as the Dynamic Speech Extractor, which adaptively
varies the gain of the FM receiver depending on the level of the noise at
the microphone of the FM transmitter. When the ambient noise level is
greater than 57dBSPL, the transmitter sends a signal to the FM receiver to
increase the gain. When the noise level decreases, the gain of the receiver
is reduced.
Phonak FM receivers offering Dynamic FM:
ML14i
MLxi, and
MyLink+.
Note: A Dynamic FM receiver must be used with a Dynamic FM transmitter
for the receiver to have Dynamic FM capabilities. If a Dynamic FM receiver
is used with a traditional FM transmitter, the receiver will not be able to
vary the gain.

6. Considerations prior to fitting an FM system
Depending upon the age of the child, Cochlear recommends at least
3 - 6 months of cochlear implant experience prior to FM use. This gives
the younger child time to develop some basic listening skills and allows
the clinician to measure baseline speech perception performance. Given
the known interference issues with FM systems in general, children
under five years of age may not be appropriate FM candidates unless
they are closely monitored.
Children should demonstrate adequate communicative skills (oral
or sign) in order to provide feedback regarding what they hear. They
should demonstrate sufficient expressive language to respond reliably
to age-appropriate listening tasks and indicate when the sound quality
suggests a problem with the FM system and/or sound processor such
that troubleshooting is required. Cochlear recommends performing a
functional listening evaluation with the FM system (see section 7 for
further information).
14 Cochlear Update | FM Solutions
It is recommended that a parent, therapist, audiologist or teacher be
trained to conduct daily listening checks to ensure the quality of sound
is optimal and to verify the proper operation of FM equipment (e.g. a
listening check with monitor earphones).
FM systems are designed to improve the signal-to-noise ratio in difficult
listening conditions, such as in background noise or when the speaker is far
from the listener. Cochlear does not recommend using an FM system in
listening environments where it is not needed.
7. Functional testing
FUNCTIONAL LISTENING EVALUATION
Confirm that the FM system is operating properly by listening with
earphones through the receiver while someone is speaking into the
transmitter (or the transmitter is plugged into an audio source). Perform
a functional listening evaluation in the classroom both with and without
the FM system. Choose a listening task in which the listener can score in
the range of 50 — 8096 correct. Administer it speech-only, in quiet, using
the processor alone at normal sensitivity. The child and examiner should
be 3 feet (1 metre) apart. The suggested presentation level is 60 dB SPL,
measured at the listener’s ear. Repeat testing in quiet through the FM
system only by setting the mixing ratio to ‘Telecoil only’ when using a
neckloop receiver, and to ‘Accessory only’ if using an ear-level or body-
worn receiver (via the CR110 Remote Assistant). Performance in these two
conditions should be similar. If not, the FM receiver settings may need to
be optimised.
Prior to completing the remainder of the functional listening evaluation,
the functional operating range of the FM system should be measured.
15 Cochlear Update | FM Solutions
FUNCTIONAL OPERATING RANGE
To measure the operating range, turn away from the listener and continue
to talk into the transmitter microphone while walking away. Instruct the
listener to indicate when the signal becomes noisy or starts to break up.
If the signal is not clear at a separation distance of 12 to 15 feet (4 to 5
metres), try a different FM channel. Make note of the distance that is
reached before the signal deteriorates. Compare the performance at this
separated distance to the performance at 3 feet (1 metre).
Repeat the listening task at a distance of 12 to 15 feet (4 to 5 metres) in
front of the listener, adding in background noise (e.g. recorded multi-
talker babble) played at approximately 65dB about 3 feet (1 metre) in front
of the listener. Performance in noise should be similar to performance in
quiet at the same distance.
Note: Some manufacturers provide a list of recommended FM channels.
The use of these channels will ensure an optimum operating range.

Cochlear Limited recommends using the following channels with the FM
systems listed in this guide to ensure optimal performance:
RECOMMENDED FREQUENCY CHANNELS
H Band: H16, H17, H18, H38, H46, H59, H77, H79, H89
N Band: N16, N17, N18, N52, N64, N73, N77, N79,
Note: Some FM systems may work on bands that are different to those
listed here. Check the manufacturer's guide for any additional channel
recommendations. These channels have been selected based on approved
bands in different countries as well as bands that provide a consistent FM
signal when testing different FM systems over a large distance (up to 90
feet or 30 metres). Cochlear recommends these bands based on testing a
number of FM systems from different manufacturers.

9. Using the CP800 Series Monitor Earphones
The CP800 Series Monitor Earphones are provided to help troubleshoot
potential issues with the FM system and CP810 Sound Processor.
To use the CP800 Series Monitor Earphones:
Turn on your CP810 Sound Processor.
Lift the accessory socket cover on the sound processor and insert
the processor end of the monitor earphones into the accessory
socket of the processor.
Ensure your FM receiver and connecting device (the Euro
Accessory Adaptor or the Freedom Accessory Adaptor with FM
cable) are joined together.
Turn the FM receiver and transmitter on.
Insert the Euro Accessory Adaptor (with FM receiver attached)
into the socket on the monitor earphones.
Note: /t is very important that you plug the earphones into the
accessory socket of the processor BEFORE you connect the
adaptor and the FM receiver to the earphones. This ensures that
the sound processor will detect both the monitor earphones and
the FM receiver.
Use the monitor earphones to listen to the signal from the FM
system.

10. Battery life when using an FM system with the CP810 Sound Processor
Many factors impact the battery life of a sound processor including the use
of some accessories. It is important to note that ear-level FM receivers that
require the use of the Euro Accessory Adaptor are active devices (i.e. they
draw power from the CP810 Sound Processor, unlike other accessories
such as the personal audio cable, which is not an active device). Therefore
use of an ear-level FM receiver with the Euro Accessory Adaptor will reduce
battery life of the CP810 Sound Processor. This reduction can range from
10-4096 of battery life, depending upon various MAP parameters and
whether an ear-level Dynamic FM receiver is used. Ear-level Dynamic FM
receivers use more power than traditional ear-level FM receivers.
If the anticipated battery life is not sufficient to support FM usage (i.e.
to enable 8-10 hours of listening), a message will be provided when
programming with Custom Sound 3.2.
@ FM accessory receiver use is not recommended with this MAP due to power
requirements The user may experience processor shutdowns, or degraded
performance near the end of battery ife when using an FM receiver. To lower MAP
power requirements, reduce maxima. reduce rate or widen pulse width
18 Cochlear Update | FM Solutions
Recipients with high powered MAPs (the battery life estimate is <19
hours with the standard battery module using two Zinc Air batteries) may
experience issues with FM use. In this scenario, the FM device exceeds
the power capability of the two Zinc Air batteries and Custom Sound 3.2
will display the message suggesting that the clinician may need to lower
the MAP stimulation rate, reduce the maxima, widen the pulse width or
recommend use of the standard rechargeable battery module.
Please note that towards the end of battery life, plugging in a coupled
ear-level FM receiver and Euro Accessory Adaptor may cause the sound
processor to shut down with the standard battery module (using two Zinc
Air batteries). The solution is to use fresh batteries when using an ear-level
FM receiver.
