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.

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.
