Cochlear Nucleus CP910 User manual

Nucleus®CP910 and
CP920 Sound Processor
User Guide

This guide is intended for Cochlear implant recipients and their carers using
Cochlear™Nucleus®CP910 or CP920 (“CP900 Series”) Sound Processors. The
processor works with your implant to transfer sound to the ear, and is made
up of a processing unit, earhook, coil, coil cable and a battery module. The
CP920 processor has no accessory socket and is
smaller than the CP910 processor.
You can power your processor with a range of
battery modules, including a tamper resistant
module using disposable batteries, standard and
compact rechargeable battery modules, and a
LiteWear cable that allows the battery to be
worn on the body.
You can control your processor as a stand-alone device using the processor’s
buttons, or by using a Cochlear Nucleus CR210 Remote Control or CR230
Remote Assistant. They allow you to control one or two processors at a time
and provide extra troubleshooting functions. For more information, please
consult your remote user guide.
People with certain types of hearing loss can wear the processor in Hybrid™
mode by adding an acoustic component which sends amplified acoustic
sound into the ear canal.
A number of tools and accessories are
supplied with your processor.
NOTE
Refer to the Warnings section for
warnings and cautions relating to the use
of the CP900 Series sound processors,
batteries and components.

Batteries
You have a choice of three battery types with the CP900 Series processors:
Battery life
Batteries should be replaced as needed just as you would with any other electronic device.
Battery life varies according to the programs used each day, the thickness of skin covering
your implant, and the size and type of battery.
The rechargeable battery’s lifespan is at least 365 charge cycles. A completely empty
rechargeable battery will take approximately four hours to recharge.
Rechargeable batteries may take longer to fully recharge with age. To get the longest life
from the rechargeable batteries, always recharge before use.
