Introduction
Purpose of this guide
This user guide is intended for recipients, parents and carers using the
Cochlear™Nucleus®CP810 Sound Processor. The guide provides step-
by-step instructions for wearing and using the processor. It also provides
guidance on how to take care of the processor.
It is important that you read and understand the warnings and
precautions information provided in this guide. The Important
Information Booklet included in the document pack you received with
your processor also contains important safety information about the
processor.
The CP810 and CR110 Troubleshooting Guide provided with
your documentation helps you identify and troubleshoot basic
processor problems.
The CochlearNucleus CP810 Sound Processor
The Cochlear Nucleus CP810 Sound Processor is used together with a
Cochlear implant to transfer sound to the cochlea, which is the inner ear.
The CP810 sound processor consists of the Cochlear™Nucleus®CP800
Series Processing Unit, battery module, coil, coil magnet and coil cable.
You can also use the Cochlear™Nucleus®CR110 Remote Assistant to
control the functions of your processor. It is an easy-to-use remote
control that allows you to communicate with up to two processors at
the same time. It also provides processor troubleshooting assistance.
For information on how to use the remote assistant with your
processor, refer to the Remote Assistant User Guide provided with your
processor documentation.

Getting to know your processor

Processor options
Depending on your listening needs, your clinician can enable the
following options on your processor:
• Listening programs to help you hear better in different listening
situations. The available programs are Everyday, Noise, Focus and
Music. For more information on these programs, see Changing
programs.
• Indicator light flashes.
• Private tones.
• Microphone sensitivity (if available) or volume settings that you
can change. For more information, see Changing loudness of
sounds.
• Telecoil/microphones and accessory/microphones mixing ratios
that you can change using the remote assistant. For more
information, refer to the Remote Assistant User Guide.
Your processor has been programmed for use with your implant only. It
is important that you only use your own processor and never swap your
processor with another person’s processor. If you have two implants,
correctly match your processor to the correct implant.
NOTE
Components described in this user guide may not be available in
all countries. Please contact your clinician for more information.

Getting to know your processor

Earhook
The earhook secures the processing unit in place on your ear. It is
attached to the processing unit and is available in a range of sizes. For
more information, see Changing the earhook.
Battery module
You can use a Cochlear™Nucleus®CP800 Series Standard Battery
Module, which uses two disposable batteries (P675 zinc air batteries), or
a Rechargeable Battery Module to power your processor.

Getting to know your processor

To prevent children from detaching the battery cover from the battery
holder, you can use the Cochlear™Nucleus®CP800 Series Tamper
Resistant Battery Cover. You can also lock the standard battery module
or the rechargeable battery module to the processing unit.
WARNING
The replacement batteries present a choking hazard if they are
swallowed by children. Always use the CP800 Series Tamper
Resistant Battery Cover for children.
Cochlear supplies a battery charger to recharge the rechargeable battery
module. For more information, see Replacing and recharging batteries.
Coil and coil cable
The coil is a small round disk that you place over the implant. It
transfers electromagnetic signals from your processing unit to the
implant. The coil is attached to a removable coil cable, which plugs into
the processing unit. The coil and coil cable are available in a choice of
colours and lengths. For more information, see Changing the coil cable.

Getting to know your processor

Coil magnet
A magnet holds the coil in place over your implant.
Figure 6: Coil magnet
Microphone protectors
The processor microphones capture sound, which is processed by the
processing unit for transfer to the implant. Microphone protectors
are designed to protect the microphones from dirt and moisture. It
is important that you keep the microphone protectors in place at all
times.

Wearing your processor
Your processor is designed to fit neatly and comfortably behind your ear.
You can also wear the processing unit behind the ear and attach the
battery module to the body. This provides greater comfort and flexibility
for both adults and children.
You can change the processor coil cable, coil magnet and earhook for
optimal comfort (e.g. if the coil cable length is too short, you can easily
change the cable to a longer one).
This section describes how to wear your processor and wearing options.
Placing your processor on your ear
To be able to hear sound from the processor, it needs to be placed on
the ear.
To place your processor on your ear:
1. Place the processing unit over your ear while holding the coil in the
other hand.
2. Place the coil on your head. The coil magnet should hold it in place
over your implant.
You may find it easier to turn on your processor before placing it on
your ear. When you turn on your processor before placing it on your ear,
you may see flashes of orange. This indicates that the coil is not placed
on your head. If the flashes do not stop even after placing the coil on
your head, see Indicator lights for more information.

Attaching the coil and coil cable
If the coil is not attached to the processing unit, or the coil cable is
not attached to the coil, you need to attach them before placing the
processor on your ear.
Attaching the coil cable to the coil
To attach the coil cable to the coil:
1. Hold the coil in one hand
and the coil cable plug in
the other hand as shown.
2. Align the coil end of the coil
cable plug with the coil.
3. Push the coil cable plug
firmly into the coil until it
clicks into place.
Attaching the coil to the processing unit
To attach the coil to the processing unit:
1. Align the coil cable plug
with the coil cable socket
on the processing unit.
2. Push the coil cable plug
firmly into the socket until
it clicks into place.
