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

Nucleus Freedom Speech Processor
Sounds received by either the microphone, in-built telecoil, an
accessory, or a mix of microphone sound and sound from the
in-built telecoil or an accessory, is coded by the Processing
Unit and transmitted through the coil to the cochlear implant.
The implant’s electrodes stimulate the cochlea’s hearing nerve
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.
Serial number
The serial number is 101005
plus the number found on
the spine of the Processing
Unit, under the microphone
protector, for example,
1010051234579
We suggest you make a note
of the full serial number for
future reference.

protector, see Care and Troubleshooting.
Other Information
For future reference, keep this manual in a safe place.
For information about the ‘H’ or Help messages, see Care
and Troubleshooting or a Freedom speech processor Quick
Reference Guide.
Your Freedom speech processor stores your first name, last
name, implant family, 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.
Program options available
Up to four speech processing programs (P1 to P4) are
available for your use.
The program components are selected at the programming
session, when your clinician includes the features you want.
By including different features, the programs can be varied to
help you hear better in different listening situations:
• Programs can include ways to improve your hearing,
using Nucleus® SmartSound™ and autosensitivity.
• While you are normally able to vary settings for
microphone sensitivity or volume, programs can also
have them set at a fixed level.

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