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.
