Nucleus Freedom Speech Processor
Introduction
Overview
The Nucleus ® Freedom™ speech processor is used together with a Nucleus
®
Freedom™ implant or a Nucleus
®
24 implant, (specifi cally 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 fi 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 identifi cation 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 identifi 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.
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 fi rst name, last name, implant type, MAP identifi er and recipient identifi 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.
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 fi xed 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 diffi 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: 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.

To change to another program, press the Select button briefl y.
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 briefl y - you will hear three tones as you change to P3. To move to P4 or P1, wait until the tones fi nish before briefl y 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 fi rst 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. Briefl y 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.

If you fi nd you often set the sensitivity higher or lower than
12, consult your clinician.
Push either
30
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.

31
Nucleus Freedom Speech Processor
In-built Telecoil
The in-built telecoil allows you to receive signals from a
• hearing aid compatible telephone
• room fi tted with an induction loop, or
• personal induction loop, such as a neck loop or cushion loop (commercially available).
The sound signal from an amplifi er, 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 fi nger 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.

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 fl 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
Troubleshooting.
35
Nucleus Freedom Speech Processor
Batteries
Batteries should be replaced when any of the following occur:
• low or fl at battery warning tones are heard
• low or fl at 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 fl at, 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 suffi cient 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 fl 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 fl 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 fi re.
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:
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 their seals removed, to allow the air to activate the batteries.
3. Turn off the speech processor and take it off.

Note: Dispose of used batteries in accordance with your local regulations. Never dispose of batteries in fi re.
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 fl 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.
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 fl oors.
• If a battery has leaked fl uid, don’t allow the fl 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.

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
• FM cable or
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
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.
Nucleus Freedom Speech Processor
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 fl ashing ‘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.
49
Nucleus Freedom Speech Processor
Accessories and the telecoil
When you are using an accessory with your speech processor, it is possible to change to use the in-built telecoil or the microphone only setting, with the accessory still attached to your speech 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

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 suffi 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 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 leafl et included in the documents you received with your speech processor.

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 fl ashing 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 fl at
• 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 fi nd the fi rst 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.
58

59
Nucleus Freedom Speech Processor
Help message
H5
Meaning Action to take Repeating help message
Program corrupted
Use a different program on your processor if possible.
Contact your clinician who will check your corrupted program(s).
H5 will remain on the display if all
4 programs are corrupted.
H5 will fl ash briefl y if only some of your programs are corrupted (for example you may be able to use P3).
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 diffi culty 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 fl at (four low tones)
A high pitched followed by a low pitched tone is heard when the wrong button is pressed.
If you have diffi culty 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 fl at.
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 fl at (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 fi xed).
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:
• fl ashes when incoming sounds are being received
• shows a slow fl ash rate as a low battery warning
Indicator light
• shows a fast fl ash rate for all other warnings. For example when the coil is off its position over the implant, or there is a sound error (H4).
The H message shows on the display to match the fl ashing light warning (for example the indicator light will fl ash 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.
• low, one battery segment is lit.
• fl at, the H1 Help message shows.
Battery full
Battery low
Battery fl at
62
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 fi 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, (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 fl 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, 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:
• Check if the microphone sensitivity or volume level is as recommended.
64
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 fi 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
• 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
Monitor earphones
Monitor earphones can be used by a hearing person to listen to the sound signal from either:
• microphone
Nucleus Freedom Speech Processor
• microphone and in-built telecoil together
