Introduction
Purpose of this manual
This User Manual provides detailed step-by-step instructions on how
to use, maintain and troubleshoot your Freedom™Hybrid™Sound
Processor.
If you are new to your processor it is recommended that you read
the Freedom Hybrid Quick Start Guide before reading this manual.
The Quick Start Guide will provide you with the essential information
you need to familiarise yourself with the basic operations of your
processor.
Once you understand the basic functions of your processor, this
manual provides more in-depth information that’s outside the scope
of the Quick Start Guide – particularly in the areas of advanced user
operations, maintenance and troubleshooting.
This manual provides the most comprehensive source of information
available for your processor.
Overview
Your processor enables the combination of electrical and acoustic
hearing in a single Behind The Ear (BTE) processor.
The processor is suitable for recipients who have residual levels of
low frequency hearing. It is used together with a Nucleus®Hybrid
Implant, Nucleus Freedom Implant or a Nucleus 24 Implant,
(specifically the CI24R and CI24M models) to transmit sound to the
cochlea.
Your processor consists of the Processing Unit, coil, Freedom Hybrid
Acoustic Component and a choice of three wearing options.
The BTE Controller allows your processor to be worn behind the ear
as a BTE Processor. It is powered by three 675 disposable batteries or
the BTE rechargeable battery.
The Mini BTE Controller also allows your processor to be worn
behind the ear as a BTE Processor. It is powered by two 675
disposable batteries.

The Bodyworn Controller is worn on the body. It uses either two
AAA nickel/metal-hydride (NiMH) batteries, or disposable alkaline
batteries.
The three wearing options can be used interchangeably with the
same Processing Unit.
For details on warnings and precautions, refer to the Warnings
and Precautions leaflet included in the documentation you
received with your processor.

Overview of your processor
components
This section of the manual describes the component parts of your
processor.
How your processor works
Sound can be received in four ways by your processor from:
The microphone•
The in-built telecoil•
An accessory•
A mix of microphone sound and sound from the in-built telecoil• or an accessory
Sound is then processed in the following way to produce hearing:
The sound is coded by the Processing Unit and transmitted1. through the coil to the cochlear implant.
The low-frequency sound is transmitted through the Acoustic2. Component directly into the ear through the earpiece.
The implant’s electrodes stimulate the cochlea’s hearing nerve3. fibres, which relay the signals to the brain to produce hearing
sensations.
Your processor has been programmed for use with your implant
only. It is important to only use your own processor, to never swap
yours with another person, and if you have two implants, to correctly
match your processor to the correct implant.

Processor with BTE or Mini BTE
Controller
Both the BTE and Mini BTE Controllers are normally attached to
the Processing Unit and worn behind the ear. The Mini BTE offers a
smaller two Zinc Air battery option than the standard BTE, providing
a smaller and lighter wearing option.
Processor with Bodyworn Controller
The Bodyworn Controller is worn separately to the Processing Unit
and attached with the Bodyworn Cable. The large screen makes
it easy to view and change settings for adult users. The Bodyworn
Controller is easily interchangeable with the BTE and Mini BTE
Controllers.
The Processing Unit
The Processing Unit, incorporating Nucleus SmartSound™technology,
is the brain of your processor, where sound signals are encoded for
transmission to the implant.
The Processing Unit is worn on the ear, with either the BTE
Controller (or Mini BTE Controller) or the shoe that connects it to
the Bodyworn Controller.
Both the coil (attached to the cable) and Bodyworn Cable are
available in a variety of lengths and colours.
The controller
In addition to housing the batteries, controllers have:
A display that indicates the operations occurring.•
Buttons that operate your processor.•
The BTE Controller contains three 675 disposable batteries or the
BTE rechargeable battery. The Mini BTE Controller contains two
675 disposable batteries. The BTE and Mini BTE Controllers attach
directly to the Processing Unit when worn.
The Bodyworn Controller can be worn in a pouch on a harness or
attached to a belt. It can also be held in a pocket or secured to your
clothing.

Freedom™Hybrid™Acoustic Component
The Acoustic Component works in a similar way to a standard
hearing aid. The Processing Unit amplifies low frequency sound and
sends it to the earpiece through the earhook and connecting cable.
The earpiece sends low frequency sound directly into your ear canal.
Acoustic Component: with earhook (1), cable (2) and earpiece (3)
Avoid placing the Acoustic Component Earpiece against the
magnet of the coil or against any other magnets, due to a low
risk of damaging the receiver in the earpiece.

Wearing your processor
System diagrams of the different wearing options can be found in
Overview of your processor components. They provide a good reference
on how to assemble your processor.
Positioning your processor and coil
Your processor is contoured to fit neatly and comfortably behind the
ear. A magnet holds the coil in place over the implant.
You may find it easier to turn your processor on before placing it on
your ear. To turn on your processor push and hold the Select button
for a few seconds, until you either hear sounds (if your processor is in
place on your head), or the active program (P1, P2, P3 or P4) shows
on the display.
Placing your processor on your ear/head
To place your processor on your ear/head:
Place the earhook over your ear while simultaneously holding1. the coil in either of your hands. Do not let the coil hang freely as
the strain can damage the cable.
Place the coil on your head; the magnet should hold it in place2. over your implant.
Place the Acoustic Component Earpiece in your ear.3.
For a more secure or comfortable fit you can:
Use a standard Hybrid earhook if you no longer use the• Acoustic Component
Adjust the coil length and magnet depth/strength•
Change the coil•
Use a Mic Lock• ™with the standard earhook
Adjust the length of the Acoustic Component Cable (this should• be performed by your clinician only)
Read the following sections for more details.

Removing your processor from your ear/head
To remove your processor from your ear/head:
Grip the earpiece with one hand and loosen it. Take care not to1. hold the earpiece by its cable.
Continue to remove the earpiece with one hand, while removing2. the Processing Unit and coil with your other hand. Take care not
to hold the Acoustic Component Cable or coil cable.
Changing the Acoustic Component
The Acoustic Component plugs into the Processing Unit at the
earhook connector. If you no longer wish to use the Acoustic
Component, you can replace it with a standard earhook that does not
include an earpiece.
It is not possible to remove the earpiece from the cable and earhook.
The earpiece is part of the Acoustic Component, which cannot be
disassembled. The Acoustic Component can only be separated from
the Processing Unit at the earhook.
The shape of the Acoustic Component Earhook cannot be adjusted
but it provides an excellent fit due to the presence of the earpiece and
connecting cable.
Two different earhooks are available:
The earhook that comes as part of the Acoustic Component•
An alternative standard earhook that enables your processor to• be worn without the earpiece and cable
To remove the Acoustic Component or standard earhook, twist the
earhook 90 degrees as shown and pull it away from the Processing
Unit, taking care not to pull the cable.

To attach the Acoustic Component or earhook to the Processing
Unit, simply push the plug on the Processing Unit into the socket of
the earhook.
To avoid damaging the cable, grip the Acoustic Component by
the earhook when pushing it in, or pulling it out. Do not hold it
by the cable.
Adjusting the coil and magnet
Make sure the coil is positioned correctly against the implant by
placing it where the magnet “pull” feels the strongest.
You can change how close the magnet sits to your head by changing
its depth in the coil, effectively changing its “strength”. You can also
replace the magnet with a stronger or weaker one if changing the
depth of the magnet in the coil is not sufficient.
Changing magnet depth
To adjust how tight the coil sits against your skin, try adjusting how
closely positioned the magnet is to your head by changing its depth in
the coil before changing the magnet itself.
Adjusting the magnet
To adjust the magnet position (depth in the coil):
Insert a thin coin or screwdriver into the magnet slot on the1. topside of the coil.
Twist in a clockwise direction from above to increase magnet2. strength, or twist in an anticlockwise direction from above to
reduce magnet strength.

Do not force the magnet to turn if it becomes difficult to turn during
insertion or removal. The movement should be smooth and turning
should need only a small amount of force. If turning becomes difficult:
The magnet may not be correctly aligned in the coil.•
You may be turning the magnet in the wrong direction.•
Changing magnet strength
To change the magnet to a stronger or weaker one:
Insert a coin or screwdriver into the magnet slot on the topside1. of the coil.
Twist in a clockwise direction from above to remove the2. magnet.
Insert the new magnet into the underside of the coil.3.
Twist in a clockwise direction with your fingers from below to4. further insert the magnet.
If necessary, use a coin or screwdriver from above to further5. adjust.
If the magnet strength is too weak the coil may fall off. If it is too
strong, it may cause discomfort or skin irritation.
Consult your clinician if you wish to change the magnet strength.
Store spare magnets safely. Store them away from credit and other
cards that have a magnetic strip.
Changing the coil
Coils are available in various colours and lengths. If you wish to
change coil colour or find that the cable is too long or too short, you
can change the coil. The coil cannot be separated from the coil cable.
To remove the coil from the Processing Unit, always hold the plug
securely with two fingers and pull it away from your processor. You
may damage the plug, cable or the Processing Unit if you pull the
cable or twist the plug.
The coil plugs into the Processing Unit as shown below. Make sure
the coil is securely attached to the Processing Unit by pushing the
plug firmly into the socket.

Changing the coil
Regularly check to see if there are any breaks in the coil cable,
particularly if you are experiencing intermittent sound. If there are
breaks you will need a new coil. If there are no visible breaks it is still
a good idea to test the coil by using a new one.
If you plug the coil cable into the Processing Unit when your
processor is turned on, your processor may turn off. If this occurs,
hold down the Select button to turn your processor back on, that is,
until you either hear sound or the display shows.
A secure fit using the Mic Lock™
When using the standard earhook instead of the Acoustic
Component, a Mic Lock™can be used to hold the Processing Unit
in place behind the ear. The Mic Lock cannot be used while the
Acoustic Component is connected to your processor.
The tube Mic Lock can be used on the BTE Controller, the Mini BTE
Controller and the Bodyworn Cable. The stirrup Mic Lock is for use
with the Bodyworn Cable only.
To fit the Mic Lock:
For the tube Mic Lock, thread the earhook and Processing Unit1. through the Mic Lock tube and move it down the unit until it fits
fi r m l y .
For the BTE or Mini BTE Controller, position the Mic Lock between
the buttons, so the transparent band covers the display. Alternatively,
clip the stirrup Mic Lock into the two holes towards the base of the
Bodyworn Controller shoe.

Put your processor on your ear.2.
Bring the tubing around to the front of your ear and up to the3. earhook. Either sized earhook can be worn with the Mic Lock.
If the tube Mic Lock does not feel comfortable, for a better fit, rotate
the band around the base of your processor.
Hold your processor firmly in place, and determine where the4. tubing should be cut.
Mark the tubing, allowing for an additional few millimetres, so it5. can attach to the earhook.
Cut the tubing only when you are certain the length will allow6. a secure and comfortable fit. It is important not to cut it too
short.
Feed it on to your earhook.7.
Fitting the Mic Lock
To wear the Processing Unit with the Mic Lock in place, fold your
ear down and gently pass your ear lobe through the loop made by
the Processing Unit and Mic Lock until it is in position on your ear.
Alternatively, bring the tubing to the front of your ear and feed it on
to your earhook.
Your processor should fit securely with the Mic Lock in place.
To remove the Processing Unit with the Mic Lock attached, fold
down your ear lobe and reverse the process. Alternatively, ease the
tubing off the earhook.
