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.

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 confi dence 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.
