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 and off.
Tip
Slowly move the phone's sound outlet over the microphones on your processor to fi nd your best position for talking on the phone.

Wear
Water, sand and dirt
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.
Your processor is water resistant with rechargeable batteries attached. But do not wear it while bathing or swimming.
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.
Fully assembled
as described
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
Aqua Accessory TBA

Wear
Sport and exercise
Use Cochlear CP900 series accessories such as the Snugfi t or Mic Lock to help hold your processor in place when you play sport or exercise.
Then check your microphone protectors.
After exercise, wipe your processor with a soft cloth to remove sweat or grime.
Change them whenever you notice signs of sweat or grime, or any change in performance.

Rechargeable batteries give you the maximum water and sweat resistance.
Childproofing Tip
Accessories like the Snugfi t 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 Snugfi t. Always ensure these are properly locked together before use.
