Important information or advice.
TIP
Time saving hint.
CAUTION (no harm)
Special care to be taken to ensure safety and effectiveness.
Could cause damage to equipment.
WARNING (harmful)
Potential safety hazards and serious adverse reactions.
Could cause harm to person.
This guide is intended for Cochlear implant recipients and their
carers using the Cochlear™Nucleus®7 Sound Processor (model
number: CP1000). The processor works with your implant to
transfer sound to your ear, and is made up of a processing unit,
earhook, coil and cable, magnet and a battery module.
You can power your processor with disposable or rechargeable
batteries.
You can control your processor by pressing its button, or by using
your Cochlear Remote Control or the Nucleus Smart App.
People with certain types of hearing loss can wear the processor
in Hybrid™mode by adding an acoustic component which sends
amplified acoustic sound into the ear canal.
A number of tools and accessories are supplied with your
processor.
NOTES
• Refer to the relevant sections for cautions and warnings
relating to the use of the Nucleus 7 Sound Processor,
batteries and components.
• Please also refer to your Patient Information document for
essential advice that applies to Cochlear implant systems.

Batteries
You have a choice of three battery types for the Nucleus 7
Sound Processor:
The disposable battery module
consists of:
• Cochlear Battery Cover
• Cochlear Battery Holder
It uses two disposable batteries and
has a tamper-resistant lock.
The Cochlear Standard Rechargeable
Battery Module
The Cochlear Compact Rechargeable
Battery Module

5NUCLEUS 7 SOUND PROCESSOR USER GUIDE
Battery life
Batteries should be replaced as needed just as you would
with any other electronic device. Battery life varies
according to the programs used each day, your implant
type, the thickness of skin covering your implant, and the
size and type of battery.
The rechargeable battery’s lifespan is at least 400 charge
cycles. A completely empty rechargeable battery will take
approximately four hours to recharge.
Rechargeable batteries may take longer to fully recharge
with age. To get the longest life from the rechargeable
batteries, always recharge before use.
To help you get the longest life from the batteries, your
clinician can set your sound processor to turn off two
minutes after you take it off your implant.

12 NUCLEUS 7 SOUND PROCESSOR USER GUIDE
Charge rechargeable batteries
There are two chargers that can be used with the
rechargeable battery modules:
• Cochlear Y Battery Charger (see page 14)
• Cochlear USB Battery Charger (see page 16).
Before you start
Your rechargeable battery module has built-in safety and
monitoring features. Read this section before using your
battery charger.
NEW BATTERIES
You need to charge new batteries before first use.
WHAT DO I DO?
• Before using a new battery module, you need to connect it to a
charger until it is fully charged.
CHARGING TEMPERATURE
The battery chargers have a built-in temperature sensor. Batteries
must be charged at 0° C – +40° C (+32° F – +104° F). If battery
module temperature is outside this range, the LED will flash orange
(error).
WHAT DO I DO?
• Charge rechargeable battery modules at a room temperature of
0° C – +40° C (+32° F – +104° F).
BATTERY HEALTH CHECK
Rechargeable battery modules have a built-in “health check”. If a
charged battery detects a problem, it will turn the sound processor
off. If the problem is fixed, it will turn back on again.
WHAT DO I DO?
• If a battery turns off, disconnect and reconnect it to your
processor. If this does not restore power, contact your clinician.

13NUCLEUS 7 SOUND PROCESSOR USER GUIDE
POWER
COMPLETELY FLAT BATTERIES
After many uses or being stored too long, some batteries may be
too flat to allow recharging.
WHAT DO I DO?
• If a rechargeable battery module is too flat to charge, the LED
will flash orange (error). Replace the battery module.
STORING BATTERIES
Your rechargeable battery module will lose some power if you do
not use it for a period of time.
WHAT DO I DO?
• Charge your battery module before storing it.
CONNECTING TO ACCESSORIES
Some accessories (e.g. monitor earphone adaptor, Roger 20
receiver) fit between the rechargeable battery module and your
processing unit.
If you leave them attached after use, this will drain the battery.
WHAT DO I DO?
• Don’t leave your battery module attached to an accessory after
use.
• Don’t attach an accessory with a rechargeable battery module
attached to the battery charger. This will cause an error.

Made for iPhone
Your Nucleus 7 Sound Processor is a Made for iPhone®/
iPod®/ iPad®hearing device. This allows you to use the
control and audio streaming functions of compatible
Apple®devices.
If you wear a sound processor on one ear and a compatible
MFi hearing aid on the other, you may be able to
simultaneously control them and stream audio using a
compatible iOS device. Your clinician can check
compatibility and set this up for you.
WARNING
Consider security when connecting your sound processor to
devices such as smartphones or tablets. Only connect to
devices that are protected, e.g. password or PIN access control.
Do not connect to devices that have had their operating
system altered.
Pair with remote devices
You need to pair your sound processor to your Cochlear
Remote Control or a compatible Apple device to use their
control and monitoring functions.
Please see their user guides for details.
NOTE
Pairing your sound processor with your Apple device does not
enable the functionality of the Nucleus Smart App. If you want
to use the app, you need to download it from the App Store®.
