Introduction
Overview
The Nucleus
®
Freedom
™
Sound 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 Sound Processor consists of a Processing Unit, coil and a choice of three Controllers.
The BTE Controller allows the Sound Processor to be worn behind the ear as a BTE Sound Processor. It is powered by three
675 disposable batteries or the BTE rechargeable battery.
The Mini BTE Controller also allows the Sound Processor to be worn behind the ear as a BTE Sound Processor. It is powered by two 675 disposable batteries.
The Bodyworn Controller is worn on the body as a body worn
Sound Processor. It uses either two AAA nickel/metal-hydride
(NiMH) batteries, or disposable alkaline batteries.
The three Controllers can be used interchangeably with the same Processing Unit.
Warning
The Freedom Sound 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 Sound 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 Sound Processor has been programmed for use with your implant only. It is important to only use your own Sound
Processor, to never swap yours with another person, and if you have two implants, to correctly match the Sound 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.

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 Sound Processor Quick
Reference Guide.
Your Freedom Sound 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 Sound 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.

Nucleus Freedom Sound 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 Sound 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

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.

The processor is programmed for the left ear
Program selection
The processor is programmed for the right ear
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 you

N31886_ISS3 D02_EN_Freedom User Manual_Content_SC.indd 28 10/04/2014 11:47:36 AM
Nucleus Freedom Sound Processor 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 Sound 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.

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. 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.
2. Continue pushing the Increase or
Decrease button until you reach the level you want.
The display will return to normal after a few seconds.
Push either
If you find you often set the sensitivity higher or lower than
12, consult your clinician.

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 Sound 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.

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 Sound 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.

Care and Troubleshooting
Care
Your Sound 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 Sound
Processor warm, and working well. In very cold weather, wear a hat or headband over the BTE Sound Processor or Processing
Unit.
If worn in hot temperatures it should work well. However, when not worn do not leave your Sound Processor in very hot areas, for example in sunlight, behind a window or in a car.
For information on the temperatures the Sound Processor is tested to, see Technical information, Environmental conditions.
Do not wear your Nucleus® Freedom™ Sound Processor while bathing or swimming. If your Sound 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 Sound Processor when applying powder, makeup or hair product. These substances can get into and damage your Sound 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 Sound Processor overnight or when you are not using it, in a dry aid kit or drying pack. Moisture or humidity may cause the Sound Processor to cut-out or stop working. Before

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
N31886_ISS3 D02_EN_Freedom User Manual_Content_SC.indd 60 10/04/2014 11:47:58 AM
Nucleus Freedom Sound 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 highpitched 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.

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 Sound 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 Sound 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 Sound 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 Sound Processor’s microphone.
If you can hear sound while using any of these options, you can use the lapel microphone with your Sound
Processor until you are able to 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 Sound 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:
• 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.
64
N31886_ISS3 D02_EN_Freedom User Manual_Content_SC.indd 64 10/04/2014 11:47:59 AM
Nucleus Freedom Sound Processor
• 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 Sound 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 Sound 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 Sound 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 Sound 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 Sound Processor. If you still hear buzzing or distorted speech, turn off your Sound Processor, take off your coil and consult your clinician.
