ESPrit 3G User Manual ♦9
Introduction
The Cochlear Implant System
The Nucleus®24 cochlear implant system consists of
three parts:
• a speech processor, in this case an ESPrit™3G
• a transmitting coil and cable
• a Nucleus 24 cochlear implant
Hearing with Nucleus®24
To produce hearing sensations, using the Nucleus 24
cochlear implant system:
• Sounds are received by the microphone positioned at
the top of your ESPrit 3G or its built-in telecoil, or a
mix of both.
• Your ESPrit 3G codes those sounds.
• Your transmitting coil transmits the coding to your
cochlear implant.
• The electrodes in your implant use this coded
information to stimulate your cochlea’s hearing nerve
fibers.
• These hearing nerve fibers relay the sound signals to
your brain, producing hearing sensations.
N94439F ISS2 D01textMAS.p65 12/14/01, 4:52 PM9

Introduction
10 ♦ESPrit 3G User Manual
Your ESPrit 3G contains a specialized computer chip.
The speech and environmental sounds are analyzed and
digitized into coded signals by this chip.A custom
modulation scheme transmits these signals to the
electrodes on your implant’s array. Signals from the
electrodes electrically stimulate your cochlea’s nerve
fibers, generating sensations that your brain perceives as
hearing.
Nucleus 24 Cochlear Implant Models
Nucleus 24 cochlear implant models available are:
• Nucleus®24
• Nucleus®24k
• Nucleus®24 Contour™
• Nucleus®24 Double Array*
ESPrit™3G Serial Number
The serial number is located under the battery cover,
next to the batteries. For your future reference we suggest
you write the number on your warranty card.
It is important that your registration card be filled out by
you or your clinician and returned to Cochlear.This
assists if repairs are required, and enables Cochlear to
meet regulatory requirements.
* Not all implants are available (approved) for supply in all countries.Your clinician will
know which implant you have.

CIS
• a directional microphone
• a built-in telecoil
- to help you hear while using the phone
- to enable wireless access to some assistive listening
devices
• a Whisper Setting for soft sounds
• clearly visible and easy to use controls
• the choice of two listening programs, customized for
different listening situations
• within each program, a choice between volume,
sensitivity or autosensitivity/volume

Transmitting Coil and Cable
The transmitting coil and cable form one unit.They are
available in four colors: beige, brown, black and grey.
The coil sits on your head over your cochlear implant. It
transmits the sound that has been coded by your ESPrit
3G across the skin to your implant’s receiver.The cable
connects the transmitting coil to your ESPrit 3G.

3. Making sure the magnet(s) and spacer(s) arrangement
has not changed, replace with the cover of your
choice.
4. Replace the screws firmly.
Magnet Strength
Magnets hold the transmitting coil over the implant.The
magnet strength determines how tightly the coil sits on
your head.
Your clinician will combine these to establish the
magnetic strength that comfortably holds your coil in
place.
It is recommended you keep the hair around your coil
area trimmed.
Warnings:
Consult your clinician if you wish to change your
magnet arrangement. If the magnet strength is too
weak the coil may fall off. If it is too strong, it may
cause discomfort or skin irritation.
Store screws, spare magnets and plastic spacers
safely. Small parts may be hazardous if swallowed or
may cause choking if inhaled.
Cable Lengths
There are a variety of cable lengths available. A short
cable is used when you wear the ESPrit 3G on the side
where your implant is located. A long cable can be used if
you wear the ESPrit 3G on the other side of your head.
Your clinician will assist you in choosing what is more
appropriate for you.
