Introduction
Purpose of this manual
This User Manual provides detailed step-by-step instructions on how
to use, maintain and troubleshoot your Nucleus Freedom Sound
Processor.
®
™
If you are new to your processor it is recommended that you read
the Nucleus Freedom Quick Start Guide before reading this manual.
The Quick Start Guide will provide you with the essential information
you need to familiarize yourself with the basic operations of your
processor.
Once you understand the basic functions of your processor, this
manual provides more in-depth information that’s outside the scope
of the Quick Start Guide – particularly in the areas of advanced user
operations, maintenance and troubleshooting.
This manual provides the most comprehensive source of information
available for your processor.
Overview
Your processor is used together with a Nucleus Freedom Implant,
Nucleus 24 Implant (specifically the CI24R and CI24M models) or a
Nucleus 22 Implant to transmit sound to the cochlea.
Your processor consists of a Processing Unit, coil and a choice of four
wearing options.
The BTE Controller allows your processor to be worn behind the ear
as a BTE Processor. It is powered by three 675 disposable batteries or
the BTE rechargeable battery.
The Mini BTE Controller also allows your processor to be worn
behind the ear as a BTE Processor. It is powered by two 675
disposable batteries.
The Bodyworn Controller is worn on the body. It uses either two
AAA nickel/metal-hydride (NiMH) batteries, or disposable alkaline
batteries.

The Nucleus Freedom Babyworn wearing system option is for
young children, allowing the BTE Controller to be separated from the
processor and worn on the child’s clothing. The processor can fit into
an adjustable earhook, which provides a better fit on the ear.
The four wearing options can be used interchangeably with the same
Processing Unit.

Overview of your processor
components
This section of the manual describes the component parts of your
processor.
How your processor works
Sound can be received in four ways by your processor from:
•
The microphone
•
The in-built telecoil
•
An accessory
•
A mix of microphone sound and sound from the in-built telecoil
or an accessory
Sound is then processed in the following way to produce hearing:
1.
Your processor captures sound.
2.
The sound is coded by the Processing Unit and transmitted
through the coil to the cochlear implant.
3.
The implant’s electrodes stimulate the cochlea’s hearing nerve
fibres, which relay the signals to the brain to produce hearing
sensations.
Your processor has been programmed for use with your implant
only. It is important to only use your own processor, to never swap
yours with another person, and if you have two implants, to correctly
match your processor to the correct implant.

Processor with BTE or Mini BTE
Controller
Both the BTE and Mini BTE Controllers are normally attached to
the Processing Unit and worn behind the ear. The Mini BTE offers a
smaller two Zinc Air battery option than the standard BTE, providing
a smaller and lighter wearing option.
Processor with Bodyworn Controller
The Bodyworn Controller is worn separately to the Processing Unit
and attached with the Bodyworn Cable. The large screen makes
it easy to view and change settings for adult users. The Bodyworn
Controller is easily interchangeable with the BTE and Mini BTE
Controllers.
Processor with Babyworn
™
The BTE with the Babyworn Wearing System provides choice in the
way children of any age wear the BTE Controller. The reduced BTE
size and weight improve comfort on the ear and the BTE Controller
provides a smaller wearing option than the Bodyworn Controller.

The Processing Unit
™
The Processing Unit, incorporating Nucleus SmartSound technology,
is the brain of your processor, where sound signals are encoded for
transmission to the implant.
The Processing Unit is worn on the ear, with either the BTE
Controller (or Mini BTE Controller) or the shoe that connects it to
the Bodyworn Controller or Babyworn wearing option.
Overview
Both the coil cable and Bodyworn Cable are available in a variety of
lengths and colours. The Babyworn Cable is available in one length
but comes in a variety of colours.
The controller
In addition to housing the batteries, controllers have:
•
A display that indicates the operations occurring
•
Buttons that operate your processor
The BTE Controller contains three 675 disposable batteries or the
BTE rechargeable battery, and is normally attached to the Processing
Unit when worn.
The Mini BTE Controller contains two 675 disposable batteries and is
always attached to the Processing Unit when worn.
The Bodyworn Controller can be worn in a pouch on a harness or
attached to a belt. It can also be held in a pocket or secured to your
clothing.
The Babyworn wearing option allows the BTE Controller to be
separated from the Processing Unit and worn on your child’s clothing.

Wearing your processor
System diagrams of the different wearing options can be found in
Overview of your processor components. They provide a good
reference on how to assemble your processor
For information on wearing the Babyworn, see Wearing the Babyworn
at the end of this chapter.
Positioning your processor and coil
Your processor is contoured to fit neatly and comfortably behind the
ear. A magnet holds the coil in place over the implant.
You may find it easier to turn your processor on before placing it on
your ear. To turn on your processor push and hold the Select button
for a few seconds, until you either hear sounds (if your processor is in
place on your head), or the active program (P1, P2, P3 or P4) shows
on the display.
To place your processor on your ear:
1.
Place the earhook over your ear while simultaneously holding
the coil in either of your hands. Do not let the coil hang freely as
the strain can damage the cable.
2.
Place the coil on your head; the magnet should hold it in place
over your implant.

For a more secure or comfortable fit you can:
•
Adjust the earhook fit.
•
Adjust the coil and magnet.
•
Change the coil.
•
Use a Mic Lock .
™
Read the following sections for more details.
Adjusting the earhook fit
Two earhooks are available, a large and a small. The large one is
intended for use by children and the smaller one by adults.
In addition, the earhook can be shaped to fit your ear better.
To shape the earhook:
1.
Remove it from the Processing Unit.
2.
Place it in hot water for a few minutes.
3.
Bend it into the shape you want.
Wearing
To change or remove the earhook, pull it away from the Processing
Unit. Replace the earhook by pushing it back into place.
Removing and attaching the earhook
Avoid twisting the earhook. It may become loose when twisted too
much.
The earhook needs to be removed when using the Nucleus Freedom
Snugfit Retention Aid (see A secure fit using the Snugfit Retention Aid).

24/10/2008 9:09:44 AM
Adjusting the coil and magnet
Make sure the coil is positioned correctly against the implant by
placing it where the magnet “pull” feels the strongest.
You can change how close the magnet sits to your head by changing
its depth in the coil, effectively changing its “strength”. You can also
replace the magnet with a stronger or weaker one if changing the
depth of the magnet in the coil is not sufficient.
Changing magnet depth
To adjust how tight the coil sits against your skin, try adjusting how
closely positioned the magnet is to your head by changing its depth in
the coil before changing the magnet itself.
To adjust the magnet position (depth in the coil):
1.
Insert a thin coin or screwdriver into the magnet slot on the
topside of the coil.
2.
Twist in a clockwise direction from above to increase magnet
strength, or twist in an anticlockwise direction from above to
reduce magnet strength.
Wearing
Adjusting the magnet
Do not force the magnet to turn if it becomes difficult to turn during
insertion or removal. The movement should be smooth and turning
should need only a small amount of force. If turning becomes difficult:
•
The magnet may not be correctly aligned in the coil.
•
You may be turning the magnet in the wrong direction.

Nucleus Freedom User Manual - 13
24/10/2008 9:09:45 AM
Changing magnet strength
To change the magnet to a stronger or weaker one:
1.
Insert a coin or screwdriver into the magnet slot on the topside
of the coil.
2.
Twist in a clockwise direction from above to remove the
magnet.
3.
Insert the new magnet into the underside of the coil.
4.
Twist in a clockwise direction with your fingers from below to
further insert the magnet.
5.
If necessary, use a coin or screwdriver from above to further
adjust.
If the magnet strength is too weak the coil may fall off. If it is too
strong, it may cause discomfort or skin irritation.
Consult your clinician if you wish to change the magnet strength.
Store spare magnets safely. Store them away from credit and other
cards that have a magnetic strip
Wearing
Changing the coil
Coils are available in various colours and lengths. If you wish to
change coil colour or find that the cable is too long or too short, you
can change the coil. The coil cannot be separated from the coil cable.
In order for the Freedom Processor to work with the N22
implant,
the N22 Processor coil must be used. To differentiate
the N22 coil and cable from the standard Freedom one, “N22”
is printed on the underside of the coil. The N22 coil also has a
green plug.
To remove the coil from the Processing Unit, always hold the plug
securely with two fingers and pull it away from your processor. You
may damage the plug, cable or the Processing Unit if you pull the
cable or twist the plug. Make sure the coil is securely attached to the
Processing Unit by pushing the plug firmly into the socket.
Regularly check to see if there are any breaks in the coil cable. If there
are, you will need a new coil. If you do not see breaks it is still a good
idea to test the coil by using a new one.

Attaching and removing the coil
If you plug the coil cable into the Processing Unit when your
processor is turned on, your processor may turn off. If this occurs,
hold down the Select button to turn your processor back on, that is,
until you either hear sound or the display shows.
™
A secure fit using the Mic Lock
A Mic Lock can be used to hold the Processing Unit in place behind
the ear.
The tube Mic Lock can be used on the BTE Controller, the Mini BTE
Controller and the Bodyworn Cable. The stirrup Mic Lock is for use
with the Bodyworn Cable.
1.
For the tube Mic Lock, thread the earhook and Processing Unit
through the Mic Lock tube and move it down the unit until it fits
firmly.
Wearing
To fit the Mic Lock:
For the BTE or Mini BTE Controller, position the Mic Lock between
the buttons, so the transparent band covers the display. Alternatively,
clip the stirrup Mic Lock into the two holes towards the base of the
Bodyworn Controller shoe.
2.
Put your processor on your ear.
3.
Bring the tubing around to the front of your ear and up to the
earhook. Either sized earhook can be worn with the Mic Lock.
If the tube Mic Lock does not feel comfortable, for a better fit, rotate
the band around the base of your processor.
4.
Hold your processor firmly in place, and determine where the
tubing should be cut.

5.
Mark the tubing, allowing for an additional few millimetres, so it
can attach to the earhook.
6.
Cut the tubing only when you are certain the length will allow
a secure and comfortable fit. It is important not to cut it too
short.
7.
Feed it on to your earhook.
Wearing
Fitting the Mic Lock
To wear the Processing Unit with the Mic Lock in place, fold your
ear down and gently pass your ear lobe through the loop made by
the Processing Unit and Mic Lock until it is in position on your ear.
Alternatively, bring the tubing to the front of your ear and feed it on
to your earhook.
Your processor should fit securely with the Mic Lock in place.
To remove the Processing Unit with the Mic Lock attached, fold
down your ear lobe and reverse the process. Alternatively, ease the
tubing off the earhook.
™
A secure fit using the Snugfit Retention
Aid
The Snugfit Retention Aid can be used to hold the Processing Unit
in place more securely than the standard earhook and is easier
to configure than the Mic Lock. The Snugfit is available in three
sizes for both adults and children: small, large and extra large. It is
easily adjustable, comfortable and robust enough to withstand the
elements of an active lifestyle. It can also be used with the Babyworn
wearing option to provide a secure fit for children.

The display generally shows the program in use, for example, P1
and whether the microphone, in-built telecoil or both are operating.
The information on the display varies according to the program and
functions being used.
When the lapel microphone is used with the BTE or Mini BTE
Controller, no M or T shows on the display.
The Bodyworn Controller display (backlight) will light up for a few
seconds when a button is pressed, or a Help message first shows on
the display.
In addition help messages may show, either as a warning or sign that
action needs to be taken. For example H2 shows for low batteries, or
H3 if the coil is not in place or is not working. For more information
on help messages, see Troubleshooting.
When the microphone sensitivity or volume is changed, the symbol,
S or V will show on the display correspondingly. This lets you know
which function you are changing. The sound level will show as a
number, and change when you push the increase or decrease button.
The display will return to the normal P status when no further
changes to the level occur.
Processor programs
Up to four sound processing programs (P1 to P4) are available for
your use, providing that your clinician has enabled them for you.
You can change programs to help you hear better in different listening
situations.
Program options available
The program levels and features are selected at the programming
session, when your clinician programs your processor to suit your
listening needs.
By including different features, the programs can be varied to help
you hear better in different listening situations:
Programs can include ways to improve your hearing, using
Nucleus SmartSound .

While you are normally able to vary settings for microphone
sensitivity or volume, your clinician can also have them set at a
fixed level within a program so they cannot be changed.

number of programs that your clinician has set up. For example, if you
only have two programs set up, it will only move through P1 and P2
(P3 and P4 will not show).
The program you select operates until you press the Select button
again. When you switch your processor off and on again, it will return
to the program and settings you were using before you switched
it off. That is, your processor will remember the last program you
used, including any changes to the microphone sensitivity and volume
settings you made.
Changing your perception of loudness
You can use the microphone sensitivity and volume controls to
change the loudness levels of the sounds you hear.
Your clinician will set up your programs so you:
•

Using SmartSound in different listening
environments
™
Your processor incorporates innovative Nucleus SmartSound
technology.
SmartSound is designed to mimic the ear’s adaptive capabilities,
delivering improved hearing outcomes and behave in the same way
as natural hearing, providing control over how sound is processed in
different listening environments.
There are various SmartSound 2 options available, grouped within
four hearing environments. The following functions may be included
as options, within a program:
•
Everyday is ideal for the typical listening conditions of everyday
life and can automatically adjust the sounds you hear for
maximum clarity and comfort.
•
Noise is suitable for environments with significant background
noise, improving the audibility of wanted sound from various
positions.
•
Focus is useful where there is significant background noise but
focus is needed on a single source of sound.
•
Music is used to listen to all types of music from any audio
source.
Discuss with your clinician how you want these options applied to
your programs. You can only use these options if your clinician has
set them up in one or more of your four programs. You can then use
a SmartSound 2 option by changing to the program(s) where it is
available.
Using the Telephone with your
processor

•
Carry spare batteries in a closed plastic bag for safety, making
sure they do not come into contact with either each other or
metallic objects, for example coins or hair clips. Any of these
situations may accidentally short circuit (and discharge) the
battery, which may heat up and even crack open.
•
Only charge rechargeable batteries. Do not recharge disposable
batteries, e.g. zinc/carbon or alkaline batteries.
•
Store batteries in cool places.
•
Do not heat batteries, for example never leave batteries in
sunlight, behind a window or in a car.
•
Never immerse batteries in water.
•
Do not deform batteries. For example, do not force them into
your processor. Do not drop batteries on hard floors.
•
If a battery has leaked fluid, don’t allow the fluid or liquid to
come in contact with skin or eyes. If contact is made, wash with
a lot of water and seek medical attention. It is always a good
idea to wash your hands after you have handled batteries.
Changing Batteries

•
Ensure your battery charger is suitable for the type of battery
you are using.
•
After storing rechargeable batteries for an extended period,
it may be necessary to charge and discharge them (that is, use
them until they are fully flat), several times to obtain maximum
performance.
•
Remove rechargeable batteries from the charger, immediately
after they are charged.
•
As you use rechargeable NiMH batteries, their battery life will
fade. When batteries no longer last for a reasonable period
of time, dispose of them carefully, in accordance with local
regulations.

To change the sound level when using microphone sensitivity, press
either the Increase or Decrease button. If not pressed again within a
short time, the display will revert to the program display.
When you change the volume level, the total sound signal changes,
that is the level of the accessory and the microphone signal change
together. Generally the volume control level should be set at 2 or
more.
Accessories
To change the sound level when using an accessory, press either the
Increase or Decrease button for more than one second. You will hear
a tone and/or see a flashing V on the display.
The balance between the amount of sound heard from the accessory
as compared with that heard from your processor microphone will
be set for each program when the clinician sets up that program.
If the sound level is unsatisfactory when you are using an accessory,
ask your clinician to change it at your next programming session.
Alternatively your clinician may give you different sound level options
on different programs.

Accessories and the telecoil
When you are using an accessory with your processor, it is possible
to switch to the in-built telecoil or the microphone only setting, with
the accessory still attached to your processor. For example, if you are
using your TV/Hi-Fi cable and then wish to use a telephone with a
telecoil induction loop, you can switch to the in-built telecoil setting
while the TV/Hi-Fi cable is still attached.
This set of actions is part of a cycle. Each time you push both the
Increase and Decrease buttons at the same time, for a few seconds,
you move on to the next setting. Starting from where you can
hear the accessory, by pushing the buttons you move to the in-built
telecoil, then to the microphone and finally return to the accessory.
To skip a setting, push the buttons a second time.
When an accessory is not attached the cycle is microphone – telecoil
– microphone.
accessories mentioned cannot be used with the BTE Mini

Care and maintenance
Cleaning the microphone protector
The microphone protector should be in place at all times. Clean
it daily with a soft brush or cloth, while it is positioned on your
processor. Do not clean the underside of the protector. Do not use
chemicals.
Cleaning the microphone protector
Replacing the microphone protector
Replace the microphone protector when sound quality is degraded
or it becomes dirty. If you are unsure if it needs to be replaced, try
using a new protector and if the sound quality improves or is louder
then dispose of the old protector. Replace the protector every
month (at the very least) to ensure optimal sound quality and hearing
performance.
You can also ask a hearing person to check the sound quality by
using the monitor earphones. Refer to Monitor earphones for further
information.

24/10/2008 9:10:32 AM
4. Attach the new
protector.
Always use the microphone protector. It protects your speech
processor from dirt and moisture.
Care
Your processor should work well, even when used in very cold or hot
outdoor temperatures. Generally, in cold temperatures your body
heat is sufficient to keep your processor warm and working well. In
very cold weather, wear a hat or headband over your processor.
If worn in hot temperatures it should work well. However, when not
worn do not leave your processor in very hot areas, for example in
sunlight, behind a window or in a car.
Care
For information on the temperature ranges your processor is tested
to perform within, see Technical information, Environmental conditions.
Do not wear your processor while bathing or swimming. If your
processor does get wet, wipe it dry with a soft cloth and place it in
the dry aid kit for at least 12 hours. If it subsequently does not work,
return it to your clinician. Cochlear Limited cannot guarantee that
they will be able to repair any water-damaged part.
Take off your processor when applying powder, makeup or hair
product. These substances can get into and damage your processor.
Avoid getting sand or dirt into any part of the system. If this happens,
shake out as much as possible, and if necessary contact your clinician
to arrange for its repair.
Storage
Store your processor overnight or when you are not using it, in a dry
aid kit or drying pack such as the Dry & Store . Moisture or humidity
may cause your processor to cut-out or stop working. Before using
the dry aid kit, read the manufacturer’s instructions for use. It is
recommended that you store your processor fully assembled.

Troubleshooting
Chapter 1
Private tones
The private tone is heard by you and by nobody else. It can be used
with each type of controller. Private tones can only be heard if your
clinician activates them for a particular program. There are two types
of tones: high pitched and low pitched.
High-pitched tones are heard when:
•
Your Processor completes a function
•
The buttons are locked or unlocked

•
You change programs. For example, when you move from P2
(program 2) to P3 (program 3), three tones are heard.
Low-pitched tones are heard when:
•
The battery/batteries are low (two low tones)
•
The batteries are flat (four low tones)
A high-pitched tone followed by a low-pitched tone is heard when
the wrong button is pressed.
If you have difficulty hearing the private tone, ask your clinician to
adjust it at your programming session.
Public tones
The public tone is only available with the Bodyworn Controller. Both
you and people around you hear it. It allows people around you to
assist you when there is an alarm, for example when the batteries are
going flat.
Public tones can only be heard if your clinician activates them for a
particular program.
Low-pitched tones are heard when:
•
Your Processor completes a function
•
The buttons are locked or unlocked
•
You change programs (for example, when you move from P4
(program 4) to program P1 (Program 1), one tone is heard)
High-pitched tones are heard when:
The battery/batteries are low (two high tones)
•
The batteries are flat (four high tones)
•
A H3 coil error or H4 audio error occurs (you will hear four
high-pitched tones, which will repeat every minute until the
problem has been fixed)
A high-pitched tone followed by a low-pitched tone is heard when
the wrong button is pressed.

It can be turned on or off in any program when the clinician sets up
each program.
When the indicator light is turned on, it:
•
Flashes when incoming sounds are being received
•
Shows a slow flash rate as a low battery warning
•
Shows a fast flash rate for all other warnings (for example when
the coil is off its position over the implant, or there is a H4
sound error)
The H message shows on the display to match the flashing light
warning (for example the indicator light will flash very quickly if the
coil is not connected properly and a H3 message will appear on the
display). Take the action suggested for the displayed H message.
Bodyworn Controller battery indicator
The display on the Bodyworn Controller includes a battery level
indicator.
When the battery is:
Full, both battery segments are lit
