Nucleus Freedom Speech Processor
Introduction
Overview
The Nucleus® Freedom™ speech processor is used together
with a Nucleus® Freedom™ implant or a Nucleus® 24
implant, (specifically the CI24R and CI24M models) to
transmit sound to the cochlea.
The Freedom speech processor consists of a Processing Unit,
coil and a choice of three Controllers.
The BTE Controller allows the speech processor to be worn
behind the ear as a BTE speech processor. It is powered
by three 675 disposable batteries or the BTE rechargeable
battery.
The Mini BTE Controller also allows the speech processor
to be worn behind the ear as a BTE speech processor. It is
powered by two 675 disposable batteries.
The Bodyworn Controller is worn on the body as a body
worn speech processor. It uses either two AAA nickel/metalhydride (NiMH) batteries, or disposable alkaline batteries.
The three 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 can be received in four ways by the Freedom
processor:
1)
by the microphone
2)
via the in-built telecoil
3)
via an accessory
4)
by a mix of microphone sound and sound from the inbuilt telecoil or an accessory.
The sound 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
fibres, 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
identification 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 identification
card and carry it with you at all times.

Nucleus Freedom Speech Processor
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.
For more information on how to remove the microphone
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 first name, last
name, implant type, MAP identifier and recipient identifier.
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.
9
Nucleus Freedom Speech Processor
Program options available
Up to four speech processing programs (P1 to P4) are
available for your use.
The program levels and features are selected at the
programming session, when your clinician programs your
Freedom speech 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.
•
The volume function may be 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 turned on.
For more information on:
•
Nucleus SmartSound, see the next section
•
microphone sensitivity and volume, see Controllers
•
how to change between and vary programs, see
Controllers, Accessories and Care and Troubleshooting

the indicator light, private and public tones, see Processing
Unit and Care and Troubleshooting
10
Nucleus Freedom Speech Processor
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 difficult 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:
soft sounds are better detected, loud sounds are more
comfortable and speech is clearer.
•
Autosensitivity adjusts the sensitivity level of the
microphone automatically for comfortable listening in
different environments. It can be used, for example, to
prevent background noise from becoming too loud such
as when driving a car. Autosensitivity will reduce the
microphone sensitivity so that the background noise is
comfortable.
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 option by
changing to the program(s) where it is available.

will allow a secure and comfortable fit.
7.
Feed it on to your earhook.
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 speech processor, with the Mic Lock in place, should fit
securely.
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.
19
Nucleus Freedom Speech Processor
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 firmly
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.

The Bodyworn Controller display has some indications
additional to those on the BTE and Mini BTE Controllers:
•
‘X’, showing that an accessory has
been activated. This may occur in
combination with the microphone.
•
a sound level indicator, that
responds to sounds picked up
by the microphone, telecoil or
accessory
• battery level indicator
• both battery segments are lit, when the battery is full
• one battery segment is lit, when the battery is low.
The Bodyworn Controller display will light up (backlight) 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 for low batteries, or
H3 if the coil is not in place or is
not working. For more information
on help messages, see Care and
Troubleshooting.

Program selection
To change to another program, press the Select button briefly.
If the private or public tone is operating, you will hear a tone
or tones indicating the program you are changing to. For
example, to change from P2 to P3, press the Select button
briefly - you will hear three tones as you change to P3. To
move to P4 or P1, wait until the tones finish before briefly
pressing the Select button again. Repeat to move to P1.
If the private or public tone is not operating, you will not hear
any tones when you press the Select button. However there
will be a slight gap in sound while changing between the
programs. To continue on to another program, wait until you
hear the sound from the new program before you press the
button again. If you press the Select button when there is no
sound, the processor will not move to the next program. You
need to wait for the sound first before you press the Select
button again.
Continue further brief pushes until you reach the program
28
Nucleus Freedom Speech Processor
you want. Your processor will only move through the 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 speech processor off and
on again, it will return to the program and settings you were
using before you switched it off. That is, the processor will
remember the last program you used, including any changes
to the microphone sensitivity and volume settings you made.
Listening controls
You can use the microphone sensitivity and volume controls
to change the level of the sounds you hear.
Your clinician will set up your programs so you:
• can change both microphone sensitivity and volume,
• can change microphone sensitivity only, or
• cannot change microphone sensitivity or volume.
Each of your programs may be set up differently.
If your clinician has enabled you to make changes, the new
microphone sensitivity and volume settings you choose will
be saved for each program. If you change to a new program,
the settings will be the same as they were when you last used
that program.
29
Nucleus Freedom Speech Processor
Microphone sensitivity
The microphone sensitivity controls the softest level of
sound picked up by the microphone. If sensitivity changes are
enabled, you can:
•
Decrease the sensitivity to reduce background noise in
noisy situations.
•
Increase the sensitivity to hear very soft sounds in quiet
situations.
To change the microphone sensitivity level:
1.
2.
Briefly push either the Increase or Decrease button.
The display will show an ‘S’ and the current microphone
sensitivity level (a number between 0 and 20). The
recommended level is 12.
Continue pushing
the Increase or
Decrease button
until you reach
the level you
want.
The display will
return to normal
after a few
seconds.
If you find you often
set the sensitivity
higher or lower than
12, consult your
clinician.
30
Push
either
Nucleus Freedom Speech Processor
Volume control
The volume controls your perception of loudness. If volume
changes are enabled, you can:
•
Reduce the volume if sounds are uncomfortably loud.
•
Increase the volume if speech, including your own voice,
is too soft.
The volume level is shown as a number between 0 and 9.
If you are adjusting the volume setting often, or if adjusting the
volume causes you discomfort, consult your clinician.
To change the volume level:
1.
Push either the Increase or Decrease button and hold
for more than one second. The display will show a ‘V’
and the current volume level.
2.
Continue pushing the
Increase or Decrease
button until you reach
the volume level you
want.
The display will return
to normal after a few
seconds.
Push
either
31
Nucleus Freedom Speech Processor
In-built Telecoil
The in-built telecoil allows you to receive signals from a
•
hearing aid compatible telephone
•
room fitted with an induction loop, or
•
personal induction loop, such as a neck loop or cushion
loop (commercially available).
The sound signal from an amplifier, TV or Hi-Fi can also be
sent from an induction loop to the telecoil.
To select the in-built telecoil, push both the Increase and
Decrease buttons at the same time, for a few seconds, until a
‘T’ shows on the display.
Hold
both
Make sure your finger
presses both sides of the
button area.
Your clinician can establish your program
to operate as either a telecoil alone,
or as a mix of your in-built telecoil and
speech processor microphone. If your
clinician sets your program as a mix of
the telecoil and microphone, this will
show as ‘MT’ on the display.
32
Nucleus Freedom Speech Processor
Sensitivity and/or volume levels can be changed when using
‘T’ or ‘MT’ in the same way as described previously. This will
increase or decrease the sensitivity of the telecoil (as well
as the microphone if ‘MT’ is used) and overall volume of the
telecoil (as well as the microphone if ‘MT’ is used).
To reset your program after using ‘T’ or ‘MT’ push all three
buttons together (Increase, Decrease and Select) for a
few seconds. The processor will reset the program to
microphone (‘M’) as well as the sensitivity and volume levels if
they were adjusted.
Button lock
The button lock can be used to prevent children from
changing the controls or to avoid accidental button presses
changing the speech processor settings.
To lock or unlock the buttons, push both the Select and
Decrease buttons for a few seconds.

You will need to unlock the
buttons before turning off the
speech processor.
To unlock the buttons, press the
Select and Decrease buttons
together for a few seconds.
The display will briefly show ‘-L’ to
indicate the buttons are unlocked.
Resetting the Freedom speech processor
To reset your processor to the
default settings (e.g. after adjusting
the microphone sensitivity or volume
levels and/or using the telecoil or an
external accessory,) press all three
buttons (Select, Increase, Decrease)
together for a few seconds.
Make sure your finger
presses both sides of the
Increase/Decrease button
area. You will hear a
sound and the display will
go blank for a moment.
34
Nucleus Freedom Speech Processor
Private and public tones
Private and public tones can be used to hear when certain
Freedom speech processor functions are started, and
warnings occur.
The private tone is heard by you, and nobody else. It can be
used with either the BTE Controller, Mini BTE Controller or
Bodyworn 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 flat.
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
Troubleshooting.
35
Nucleus Freedom Speech Processor
Batteries
Batteries should be replaced when any of the following occur:
•
low or flat battery warning tones are heard
•
low or flat battery help message shows on the display
(H1 or H2)
•
low battery warning shows on the Bodyworn Controller
(only a small segment of the battery is on the 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 flat, or when the battery
holder is to be stored for a period of time.
Use only battery types recommended by your clinician or
Cochlear. Other types may not have sufficient energy to allow
your Nucleus Freedom speech processor to either function
properly or last for a long time.
When using disposable batteries, never mix fully charged
batteries with partially charged ones. Always change each
battery. It only takes one low or flat 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 fluids and cause
damage if left inside your Freedom Controller.
Dispose of used batteries in accordance with your
local regulations.
Never dispose of batteries in fire.
36
Nucleus Freedom Speech Processor
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 and Mini BTE Controller
The Freedom BTE Controller uses three high power
675 zinc air batteries (the Mini BTE Controller uses two).
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
seal or tab.
To change the batteries:

Nucleus Freedom Speech Processor
Bodyworn Controller
Your Freedom Bodyworn Controller holds two AAA
batteries. Cochlear recommends rechargeable nickel/metalhydride (NiMH) batteries, or disposable alkaline batteries. For
optimum battery life of rechargeable batteries, use NiMH
batteries of at least 800mAh capacity.
Replacing the batteries
To replace the batteries:
1.
Turn off your speech processor.
2.
Firmly hold the cover and slide it down, to reveal the
battery compartment.
41
Nucleus Freedom Speech Processor
3.
4.
Remove the old batteries
and replace with new ones.
Make sure the + and
- symbols on the batteries
match the + and - symbols
in the compartment.
+
Slide the cover back until it
clicks into place.
+
Note: Dispose of used batteries in accordance with your local
regulations. Never dispose of batteries in fire.
Recharging NiMH batteries
Use the charger supplied to charge NiMH batteries for use
with your bodyworn battery pack. For more information on
how to use it, see the instructions supplied with the charger.
Caution:
Do not use the charger for zinc/carbon, alkaline,
lithium or any other disposable batteries.
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.
42
Nucleus Freedom Speech Processor
•
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.
43
Nucleus Freedom Speech Processor
General precautions for 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 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 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.
For more information, see Care and Troubleshooting.

Using accessories
Lapel microphone
When using a lapel microphone, you will only hear
sounds through the lapel microphone. Adjusting either the
microphone sensitivity or volume changes the level of sound
heard through the microphone.
Audio mixing and other accessories
The sound from the speech processor’s microphone will be
mixed with that from the:
•
personal audio cable
•
TV/Hi-Fi cable
•
FM cable or
• FM system
If both the accessory and
microphone are activated, both an
‘M’ and ‘X’ show on the Bodyworn
Controller display.
The microphone sensitivity button varies the level received by
the microphone, while the sound from the accessory remains
constant.
To hear more environmental sound, press the Increase button.
To hear less environmental sound, press the Decrease button.
If you only want to hear the signal from the accessory, press
the Decrease button until the microphone sensitivity is
zero (0). This will switch off the external sounds received by
the microphone.
When the accessory has a volume level control, it can be
used to change the level of sound being heard from the
accessory.
48
Nucleus Freedom Speech Processor
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

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.
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 the speech
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.

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 sufficient 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 hair product. 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
54
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 battery/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 the contacts clean where the Processing Unit and either
the BTE Controller, Mini 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.
55
Nucleus Freedom Speech Processor
Disposal
Dispose of electrical components in accordance with your
local regulations.
Warnings and precautions
For more details on warnings and precautions, refer to the
Warnings and Precautions leaflet included in the documents
you received with your speech processor.
Microphone protector
The Freedom speech processor is designed to be used with
the microphone protector in place at all times.
The microphone protector can be replaced when it becomes
dirty, or the sound quality deteriorates.
You may first ask a hearing person to check the sound quality
by using the monitor earphones. Refer to Monitor earphones
for further information.
To remove the microphone protector from the Processing
Unit:

Troubleshooting
Your Freedom speech processor has several indicators of
possible problems:
•
H1 - H5 messages show on the display
•
battery level indicator shows on the display (Bodyworn
only)
•
indicator light changes its flashing pattern (if activated)
•
tone sound is heard (if activated)
These are indicators that some action is required. For
example, these indicators may occur when:
•
sound stops or becomes intermittent
•
battery life is running down or batteries are flat
•
the coil has come off the head or the connection is
damaged
This section describes what to do when a problem arises.
After each step, check if you hear any sound.
You may find the first H message is replaced with another.
Take the action suggested to rectify that problem. Continue
until no H messages are displayed.
If there is still a problem indicated after you have made all the
checks, contact your clinician. The speech processor should
only be repaired by a person authorised by Cochlear Limited.
Alternatively you may experience other problems which are
listed under Other problems.

Private and public tones
Private and/or public tones indicate when a particular
function of the speech processor has been used. Tones can
only be activated or adjusted by your clincian.
To stop either the private or public tone, press any button.
If you have difficulty hearing the private tone, ask your
clinician to adjust it at your programming session.
Private tones
The private tone is heard by you, and nobody else. It can
be used with the BTE Controller, Mini BTE Controller and
Bodyworn 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:
•
the processor completes a function
•
the buttons are locked or unlocked
•
you change programs. For example, when you move
from program 2 to program 3, three tones are heard.
60
Nucleus Freedom Speech Processor
Low pitched tones are heard when:
•
the battery/batteries are low (two low tones)
•
the batteries are flat (four low tones)
A high pitched 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. 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 flat.
Public tones can only be heard if your clinician activates them
for a particular program.
Low pitched tones are heard when:
•
the processor completes a function
•
the buttons are locked or unlocked
•
you change programs. For example, when you move
from program 4 to 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)
•
H3 coil error or H4 audio error occurs (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
61
Nucleus Freedom Speech Processor
heard when the wrong button is pressed.
Indicator light
The red indicator light can also
be turned on by the clinician in
the 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 sound error (H4).
Indicator light
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.

Nucleus Freedom Speech Processor
Other problems
You may encounter some other problems that the H
messages, indicator light and tone don’t directly refer to. Take
the following steps to try to fix 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, (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 by pressing all three
buttons for more than one second.
•
Try using the speech processor either with the in-built
telecoil or an accessory, when available. If sound is heard
(and the indicator light flickers 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,
you can use the lapel microphone with your speech
processor until you are able to return it to your clinician
for repair.
•
Have a hearing person use the monitor earphones to
63
Nucleus Freedom Speech Processor
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.
•
Clean the protective cover on the base of the BTE
battery holder or Mini 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 (a H3 message will tell you this)
•
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:
•
64
Check if the microphone sensitivity or volume level is as
recommended.
Nucleus Freedom Speech Processor
•
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 one of the Controllers
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.
65
Nucleus Freedom Speech Processor
Continue to use your speech processor until you are able to
return the Processing Unit to your clinician for repair.
5. Electromagnetic interference
Try moving away from any electronic device that may be
causing interference, for example buzzing sounds or distorted
speech.
Most electronic devices produce electromagnetic fields.
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
•
fluorescent 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.
66
Nucleus Freedom Speech Processor
Monitor earphones
