About
The Cochlear Nucleus CP900 Series Sound Processors works with your Cochlear
Implant to transfer sound to the ear. Your processor is made up of a processing
unit, earhook, coil, coil cable and a battery module.
You can choose either the CP910 or the CP920 processing unit. The CP920
processing unit is smaller than the CP910 and has no accessory port.
You can power your processing unit with a range of battery modules. The range
includes a tamper resistant battery module that uses disposable batteries, a
standard rechargeable and compact rechargeable battery module, and a LiteWear
cable that allows the battery to be worn on the body.
You can control your sound processor as a stand-alone device by pressing the
buttons on the processor. All stand-alone functions are covered in this guide.
You can also choose a Cochlear Nucleus CR210 Remote Control or CR230 Remote
Assistant to control your processor. The remotes let you control one or two
bilateral processors at a time and can provide extra troubleshooting functions. All
remote functions are covered in separate user guides.
People with certain types of hearing loss can wear the processor in Hybrid mode
by adding an accessory called the acoustic component. The acoustic component
sends extra acoustic sound into the ear canal. Hybrid mode must be set up by
your clinician.
A number of tools and accessories are supplied with your sound processor. The
most important of these are your drying pack, screwdriver, and microphone
protector applicator with removal tool.
Warning
Do not allow children under
three to play with the system.
Removable parts of the system
can be lost or may be a choking
hazard.

Talk on the phone
Listen to hearing loops and hear voices on the telephone more clearly with the
telecoil (t-switch). Your processor can be set up with either manual or auto telecoil.
Auto telecoil turns the telecoil on and off whenever you use a phone or move in
and out of range of a hearing loop.
Whether you choose auto or manual telecoil, you can control the telecoil with
your remote or just turn it on and off with your processor.
Quick-press the top button to turn telecoil on

Note
Certain electronic devices or machinery may
automatically turn on Auto Telecoil. If this
happens, move away from the device or machinery
and wait a few seconds for Auto Telecoil to turn

Water, sand and dirt
Your processor is water resistant
with rechargeable batteries
attached. But do not wear it while
bathing or swimming.
Your processor is dust resistant
with rechargeable batteries
attached. But do not get sand or
dirt into any part of your sound
processor.
Your sound processor is resistant to water, sand and dust. However, it is still a
precision electronic device so the following precautions should be taken.
If your processor ever does get wet,
dry it with a soft cloth, change the
microphone protectors and place it
in a drying kit for 12 hours.
If sand or dirt ever do enter the
system, shake the components
carefully to remove it and change
the microphone protectors.
Your processor is protected against
failure from dust and temporary
immersion in water (IP57) when
you wear it with:
• a rechargeable battery module
• a coil and coil cable
• a closed accessory port
• no acoustic component

Sport and exercise
Then check your microphone
protectors.
Change them whenever you notice
signs of sweat or grime, or any
change in performance.
After exercise, wipe your processor
with a soft cloth to remove sweat or
grime.
Use Cochlear CP900 series
accessories such as the Snugfit or
Mic Lock to help hold your processor
in place when you play sport or
exercise.
Accessories like the Snugfit or Mic Lock can help hold a processor on
a child's ear. Children under three years of age should only use tamper
resistant accessories such as the tamper resistant earhooks, tamper
resistant battery cover and tamper resistant Snugfit. Always ensure these
are properly locked together before use.
Childproofing Tip
A thin sweatband or skullcap worn
over the sound processor can make
wearing a helmet easier.
Rechargeable batteries give you

The Cochlear Nucleus CP900 Series LiteWear Cable allows any standard (not
compact) battery module to be worn on the body - so only the processing unit is
worn on the ear. You can order LiteWear at <TBA> or talk to your clinician.
LiteWear is made up of a LiteWear cable,
case and a choice of fixing aids.

Childproofing Tip
Attach the LiteWear case between the shoulder blades of very young children
to help prevent tampering.
Travel
You can travel with your sound processor with confidence because Cochlear is
supported by clinics all over the world.
Take a printout of your most recent program in case you need help with your
processor.
If you have a back-up sound processor, check that it is programmed correctly
and take it with you.
It's okay to move through metal detectors and full body scanners with your
sound processor on. To avoid any possible buzzing sounds in your ear, turn
off the telecoil.
Ask your clinician for a Nucleus 6 ID card. In the unlikely event that your
implant sets off a metal detector the ID card will help you explain that you
have an implanted medical device.
Do not place sound processors directly onto conveyor belts as you move
through airports. Place them in a bag or plastic tray.
Your sound processor will not interfere with a plane's navigation system so
you won't need to turn it off during takeoff and landing.

Audio accessories
The accessory port on the CP910
processing unit lets you connect a
wide range of audio accessories.
The Cochlear Nucleus Lapel
Microphone can make conversation
easier in noisy environments.
Parents and carers can use
the Cochlear Nucleus Monitor
Earphones to check the processor
and audio accessories are working.
For example, a Cochlear Nucleus
personal audio cable let you listen
to iphones, computers, TV sets
etc. Bilateral recipients can listen in
stereo.
TBA
You can order audio accessories at <TBA> or talk to your clinician.
Note
The CP910 processing unit is compatible with the CP800 range of audio
accessories. You can order adaptors to make your CP910 processor
compatible with Freedom and Euro accessories. Your CP910 processor is
NOT compatible with the BAHA range of audio accessories.
Warning
Always use the Mains Isolation Cable when connecting any Personal Audio
Cable (including Bilateral) to:
• a mains powered device e.g. TV.
• a battery powered device that is connected to mains power (e.g. a
laptop connected to an electric outlet for charging).
Do not use excessive force, twist or pull on accessories when connecting
them to the processor or at any time while they are connected.
When you connect an audio
accessory, your processor
automatically detects it.
If applicable, insert the other end of
the audio accessory cable into the
compatible device e.g. Ipod.

Battery life expectancy
Battery life varies according to the programs used each day, the thickness of skin
covering your implant, and the type of battery. Use 675 zinc/air batteries in the
standard battery module for longest battery life. To get the longest life from the
rechargeable batteries, always recharge before use. Rechargeable batteries may
