Introduction
This manual is for users of the SPrint™Speech
Processor, which is part of the Nucleus®24
cochlear implant system. The SPrint is used with
the following Nucleus 24 cochlear implant systems:
• Nucleus®24
• Nucleus®24k
• Nucleus®24 Contour™
The SPrint is also used with the auditory brainstem
implant, the Nucleus®24 ABI. Please refer to the
User Manual Addendum for the SPrint speech
processor and accessories, if you are a Nucleus 24
ABI recipient.
Nucleus 24 implant systems consist of three parts:
• the implant
• the speech processor
• the headset
Together these three parts convert sounds from the
environment into coded electrical information that
is interpreted by your brain as sound.

Understanding the Cochlear Implant System
The SPrintTM Speech Processor
The speech processor is a small computer worn on
your body and connected to the headset by cables.
It receives sounds from a microphone in the
headset, converts them to electrical signals and
sends the signals back to the headset.
