Nucleus Freedom Speech Processor
Introduction
Overview
The Nucleus® Freedom™ speech processor is used together
with a Nucleus® Freedom™ implant, to transmit sound to
the cochlea.
The Freedom speech processor consists of a Processing Unit,
coil and a choice of two Controllers.
The smaller BTE Controller allows the speech processor
to be worn behind the ear as a BTE speech processor. It is
powered by three 675 zinc air batteries.
The larger Bodyworn Controller is worn on the body as
a body worn speech processor. It uses either two AAA
nickel/metal-hydride (NiMH) batteries, or disposable alkaline
batteries.
The two Controllers can be used interchangeably with the
same Processing Unit.
Warning
The Freedom speech processor contains small parts
that may be hazardous if swallowed, or may cause
choking if ingested or inhaled.
Infants and young children should wear the Bodyworn
Controller in a Cochlear-provided, tamper-resistant
pouch.

Nucleus Freedom Speech Processor
Sound received by either the microphone, in-built telecoil, an
accessory, or a mix of microphone sound and sound from the
in-built telecoil or an accessory, is coded by the Processing
Unit and transmitted through the coil to the cochlear implant.
The implant’s electrodes stimulate the cochlea’s hearing nerve
f bres, which relay the signals to the brain to produce hearing
sensations.
Your speech processor has been programmed for use with
your implant only. It is important to only use your own
speech processor, to never swap yours with another person,
and if you have two implants, to correctly match the speech
processor to the correct implant.
Warranty, registration and patient
identifcation card
Your warranty is enclosed.
Please complete the registration card and return it to
Cochlear within 30 days of receiving your product.
You should also complete the supplied patient identif cation
card and carry it with you at all times.
Serial number
The serial number is 101005
plus the number found on
the spine of the Processing
Unit, under the microphone
protector, for example,
1010051234579
We suggest you make a note
of the full serial number for
future reference.

protector, see Care and Troubleshooting.
Other Information
For future reference, keep this manual in a safe place.
For information about the ‘H’ or Help messages, see Care
and Troubleshooting or a Freedom speech processor Quick
Reference Guide.
Your Freedom speech processor stores your f rst name, last
name, implant family, MAP identif er and recipient identif er.
This allows you to
•
attend another clinic for programming, when you wish
•
identify a speech processor as your own.
Access to this information occurs when the clinician opens
the program. That is, it is only able to be accessed in a
programming session.
Program options v
aailable
Up to four speech processing programs (P1 to P4) are
available for your use.
The program components are selected at the programming
session, when your clinician includes the features you want.
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™ and autosensitivity.
•
While you are normally able to vary settings for
microphone sensitivity or volume, programs can also
have them set at a f xed level.

•
Either the microphone sensitivity or volume function
may be disabled, that is, turned off.
•
The indicator light and private tones can be activated or
turned on at the programming session. In addition, users
of Bodyworn Controllers can have public tones and
backlighting to the display activated, or turned on.

Nucleus® SmartSound™
The following functions may be included as options, within a
program:
•
Beam™ allows you to focus on the sounds coming from
the direction in which you are looking. It can be used, for
example when you are talking with someone in a crowd,
where there is a lot of distracting noise behind or beside
you.
•
Whisper™ is better able to detect soft sounds in quiet
situations. It can be used, for example when you are in
a lecture or meeting where it is diff cult to hear from a
distance.
•
ADRO™ makes automatic adjustments where there
are large changes in sound between loud and soft. It
can be used, for example where there is a lot of noise:
10
N31018F Iss2D02textmas.indd 10
8/06/2005 2:09:51 PM

soft sounds are better detected, loud sounds are more
comfortable and speech is clearer.
Discuss with your clinician how you want these options
applied to your programs. To use them, select a program
where they have been included.

Coil
The coil transmits the encoded information to your cochlear
implant.
A magnet holds the coil in place, over the implant.
Magnet
Turn the magnet in either
direction, to adjust how
tightly it is held to your head
The closer the magnet is to
the head, the more f rmly
it is held in place, and vice
versa.
If the magnet strength is too weak the coil may fall off. If it is
too strong, it may cause discomfort or skin irritation.
Warnings:
Consult your clinician if you wish to change your
magnet strength.
Store spare magnets safely. Store them away from
credit and other cards that have a magnetic strip.
Small parts may be hazardous if swallowed or may
cause choking if ingested or inhaled.
Coil connection
The coil plugs into the Processing Unit as shown.
Always hold the plug securely with two f ngers when
removing the plug from the Processing Unit. You may damage
the plug, cable or processing unit if you either pull the cable
or twist the plug.

Program selection
To change to another program, push the Select button brief y
to move to the next program.
If you have the private tone operating, or with the Bodyworn
Controller either the private or public tone, when you change
to another program, the number of tones heard relates to
the program you are moving to. For example, if you are on
P2 and press Select, three sounds will be heard as you move
to P3. If you wish to move to P4 or P1 you need to wait until
the sounds f nish before brief y pushing the Select button
again. Repeat to move to P1.
If the private tone or public tone is not operating, no tone
will be heard when the Select button is pressed. However
there will be a slight gap in sound between the programs. If
you wish to continue to move on to another program, wait
until you hear the sound from the new program before you
press the button again.
That is, pressing the Select button when the sound gap is
occurring will not move the speech processor on to the next
program. You need to wait for the sound f rst before you
again press the Select button.
Continue further brief pushes until you reach the program
you want. It will skip the setting where there is no program.
For example, if you only have two programs it will only move
through two settings.
The program selected operates until you press the Select
button again. When you switch your speech processor off and
on again, it will remember the last ‘active’ program, including
the microphone sensitivity and volume settings you were
using.

8/06/2005 2:10:59 PM
Nucleus Freedom Speech Processor
Listening contr
ols
You can use the microphone sensitivity and volume controls
to change the level of the sounds you hear.
You can adjust both the microphone sensitivity and the
volume levels for any program, unless they have been
set at a f xed level by your clinician, when the programs
were established. Generally, you are most likely to vary the
microphone sensitivity, as you adjust to environmental sounds.
The microphone sensitivity and volume settings are saved
with the particular program. If you change to a new program,
the level will be the same as previously used with that
program, that is, the last saved value for that program.
Once you f nd the level you want and you stop making
changes, the display will go back to the normal display after a
few seconds.
Whenever you wish to again change the level, repeat the
process.
To change between adjusting the microphone sensitivity and
volume, when both are available, press either the Increase or
Decrease buttons for at least a few seconds.
If your clinician has chosen to disable the microphone
sensitivity in a program, it will not operate and you will go
immediately to the volume setting when you press either side
of the Increase/Decrease buttons.
Similarly if your clinician has chosen to disable the volume
control, it will not be available.

The private tone is heard by you, and nobody else. It can be
used with either Controller.
The public tone is only available with the Bodyworn
Controller. It is heard by both you and people around you.
It allows people around you to assist you when there is an
alarm, for example when the batteries are going f at.
When using the Bodyworn Controller, both the private and
public tones can operate, or either one.
If you wish to use one or both of the tones, ask the clinician
to include them in your programs.
To stop the tone, press any button.
For more information on what the tones indicate, see

Batteries
Batteries should be replaced when any of the following occur:
•
low or f at battery warning tones are heard
•
low or f at battery help message shows on the display
(H1 or H2)
•
low battery warning (the half lit battery) shows on the
Bodyworn Controller display
•
you stop hearing sound
•
the sound you hear becomes intermittent.
For information on the warning sounds or indicators, see
Troubleshooting.
Remove batteries when they are f at, or when the battery
pack is to be stored for a period of time.
Use only battery types recommended by your clinician or
Cochlear. Other types may not have suff cient energy to allow
your Nucleus Freedom speech processor to either function
properly or last for a long time.
Never mix fully charged batteries with partially charged ones.
It only takes one low or f at battery to stop the processor
from working. Similarly, never mix brands or battery types, for
example, zinc air with alkaline batteries.
Warnings:
Flat batteries may leak corrosive f uids and cause
damage if left inside your Freedom Controller.
Dispose of used batteries in accordance with your
local regulations.
Never dispose of batteries in f re.

Do not let children replace batteries without adult
supervision.
Make sure that batteries are kept out of reach of
young children.
Batteries can be harmful if swallowed. If swallowed,
seek prompt medical attention at the nearest
emergency center or Poisons Information Center.
BTE Controller
Your Freedom BTE Controller uses three high power
675 zinc air batteries. Silver Oxide or alkaline batteries can
also be used in very humid conditions: your Freedom BTE
speech processor will only operate for a few hours when
Silver Oxide or alkaline batteries are used. Do NOT use
rechargeable NiMH button cells (HB 116/054).
High Power 675 zinc air batteries are sealed, usually with a
tab. Always remove the seal or tab at least one minute before
using, to allow air access to the battery, so it can operate.
To change the batteries:
1.
Remove the new set
of batteries from their
pack and make sure
the seals are removed.
2.
Let the new batteries
stand for one
minute, outside of
their packaging with

Nucleus Freedom Speech Processor
Always ensure the batteries are placed so the + and
- symbols on the batteries match the + and - symbols
in the compartment.
Generally, the following precautions apply so you can get the
most out of your rechargeable batteries:
•
Ensure your battery charger is suitable for the type of
battery you are using.
•
Only charge rechargeable batteries. Do not recharge
disposable batteries, e.g. zinc/carbon or alkaline batteries.
•
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 f at), 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.

General precautions or
f the use of batteries
Generally, the following precautions apply so you can get the
most out of your batteries:
•
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
hairclips. Any of these situations may accidentally short
circuit and thus discharge the battery, which may heat up
and even crack open.
•
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 speech processor. Do not drop batteries
on hard f oors.
•
If a battery has leaked f uid, don’t allow the f uid 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.

Care and Troubleshooting
Care
Your speech processor should work well, even when used
in very cold or hot outdoor temperatures. Generally, in cold
temperatures your body heat is suff cient to keep the speech
processor warm, and working well. In very cold weather,
wear a hat or headband over the BTE speech processor or
Processing Unit.
If worn in hot temperatures it should work well. However,
when not worn do not leave your speech processor in very
hot areas, for example in sunlight, behind a window or in a car.
For information on the temperatures the speech processor is
tested to, see Technical information, Environmental conditions.
Do not wear your Nucleus® Freedom™ speech processor
while bathing or swimming. If your speech processor does
get wet, wipe it dry and place it in the dry aid kit for at least
twelve hours. If it then does not work, return it to your
clinician. Cochlear cannot guarantee that they will be able to
repair any water-damaged part.
Take off your speech processor when applying powder,
makeup or hairspray. These substances can get into and
damage your speech 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 the speech processor overnight or when you are
not using it, in a dry aid kit or drying pack. Moisture or
humidity may cause the speech processor to cut-out or stop
49
N31018F Iss2D02textmas.indd 49
8/06/2005 2:12:01 PM
Nucleus Freedom Speech Processor
working. Before using the dry aid kit, read the manufacturer’s
instructions for use.
To store your speech processor overnight, you may either
leave your batteries in the Controller, or remove the battery
holder from the Controller and place it separately, with the
batteries in the holder, in the drying kit.
Warning:
Keep the drying chemical material away from young
children. Swallowing this material can cause serious
internal injuries.
For long term storage, remove the batteries from the
Controller. Remember to store them separately, to avoid
them from shorting each other.
You can also buy dry aid kits or drying packs that are able
to be used with your speech processor, from an electronics
store or pharmacy.
Cleaning
Keep battery contacts clean: use a moist cotton bud or swab
to gently clean the battery contacts. Take care not to apply
force, that may damage the contacts.
If batteries are dirty, wipe them with a clean DRY cloth. Be
careful to keep batteries dry and free from moisture.
Keep clean the contacts where the Processing Unit and either
the BTE Controller or Bodyworn Shoe connect: use a swab
dampened with medicinal alcohol to gently clean the contacts.
To clean external parts of the system, wipe gently with a
cloth slightly dampened with mild detergent. Regular cleaning
prevents dirt from building up.

messages, indicator light and tone don’t directly refer to. Take
the following steps to try to f x the problem.
If there is still a problem after you have made all the checks,
contact your clinician. The speech processor should only be
repaired by a person authorised by Cochlear Limited.
1. No sound
If sound stops, check which H message is showing and follow
the suggestions in the Help message table.
If the H4 message is showing:
•
Turn the speech processor off and then on.
•
Increase the microphone sensitivity or volume level.
If the level is very low, that is at around 0, and you are in
a very quiet room, the H4 message may show.
If no sound is heard, and the H4 message remains, reset
the level to the original position. If you leave it at the
higher level and change to use the in-built telecoil or
connect an accessory then, if heard, the sound will be
very loud.
•
Try using the speech processor either with the in-built
telecoil or an accessory, when available. If sound is heard
and the indicator light f ickers if activated, when the
in-built telecoil or accessory is used, then there is
probably a problem with the speech processor’s
microphone.
If you can hear sound while using any of these options,
for continuing short term use, you can use the lapel

microphone with your speech processor. Return it to
your clinician for repair.
•
Have a hearing person use the monitor earphones to
check if sound is being received. Refer to the Monitor
earphones section following for further information.
2. Intermittent sound
If sound is intermittent:
•
If you are in a quiet place, move to where there is a little
more noise. It may be the sound level is very low.
•
Turn the speech processor off and then on.
•
Change the batteries - make sure they are fresh and of
the same type and make.
•
Check the batteries are correctly inserted.
•
Check the battery terminals are clean.
•
Wash or change the protective cover on the base of the
BTE battery holder.
•
Change your battery holder.
•
Check the coil and its cable for broken or twisted wires.
•
Check the coil is properly connected to the Processing
Unit.
•
Replace the coil.
•
Have a hearing person use the monitor earphones to
check if sound is being received. Refer to the Monitor
earphones section following for further information.
•
Change your Controller.

3. Uncomfortable sound
If the sound level is not comfortable, for example when the
volume is low and the background noise is too high:
•
Check if the microphone sensitivity or volume level is as
recommended.
•
Change the level.
•
Speak into the microphone and watch how the indicator
light responds, if it is on in that program.
•
Change to another program to check if that program is
more comfortable, or to use a SmartSound™ function
better suited for the sound.
•
Wash or replace the microphone protective cover.
•
Use the lapel microphone and/or monitor earphones to
monitor the sound being received.
•
Ask your clinician to check your program setting(s) and
discuss whether you need a different program setting.
4. Display not showing
The speech processor may still operate when the display is
not showing.
Stop the power to the Processing Unit, and then restart it. To
stop the power, you can either:
•
Hold down the Select button until the speech processor
is off.
•
Twist the Processing Unit and either the BTE Controller
or the Bodyworn Controller shoe until they no longer
connect, then twist them back into place again.
•
Slide the battery holder out, then in again.

After you have done one of the above, hold down the Select
button to turn the speech processor back on, that is, until you
either hear sound or the display shows.
Repeat the above steps. If the display is still not showing,
follow the checks suggested for when the sound is
intermittent.
Continue to use your speech processor until you are able to
return the Processing Unit to your clinician for repair.
5. Electromagnetic interf
erence
Try moving away from any electronic device that may be
causing interference, for example buzzing sounds or distorted
speech.
Most electronic devices produce electromagnetic f elds.
Headset cables, like antennae, pick them up. Common sources
of interference include:
•
radio and TV transmission towers
•
mobile phone towers
•
shopping centre and airport security systems
•
some digital mobile phones
•
battery chargers
•
f uorescent lighting
•
mains power boards
The electromagnetic interference (EMI) will be no louder
than your programmed levels and will neither hurt you nor
damage your speech processor. If you still hear buzzing or
distorted speech, turn off your speech processor, take off
your coil and consult your clinician.
