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 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.
Behind the Ear (BTE) parts (standard)
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.

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.
