2NUCLEUS®7 AQUA+ USER GUIDE
The Cochlear™Nucleus® 7 Aqua+ is a re-usable sealable
cover that, when used with the Cochlear Nucleus 7 Aqua+
Coil, keeps your Cochlear Nucleus 7 Sound Processor (model
number: CP1000) dry during use in or around water (e.g. when
swimming, surfing, or just having fun splashing around). It is
worn behind the ear with your sound processor sealed inside.
The Nucleus 7 Aqua+ is intended for use by recipients using
the Nucleus 7 Sound Processor with rechargeable batteries. It
should only be used by recipients who can either remove the
sound processor themselves if it’s causing discomfort or who
can indicate any discomfort to their parent or caregiver.
You must use a Cochlear Standard Rechargeable Battery
Module or Cochlear Compact Rechargeable Battery
Module for your sound processor to work inside Aqua+.
Zinc air batteries will not work as they need air and there is no
air inside Aqua+ when it’s sealed.
The Nucleus 7 Aqua+ Coil is used in place of your usual
coil while your sound processor is inside your Aqua+. It has a
special plug that creates a seal when connected to your sound
processor’s coil socket through the coil plug hole in Aqua+. As
with your usual coil, a coil magnet screws into the Aqua+ coil
and holds it against your implant.
NOTES
• You cannot use your Nucleus 7 Sound Processor in Hybrid™
mode with Aqua+.
• You cannot use your Nucleus 7 Sound Processor with any of
the Cochlear retention accessories (e.g. Snugfit, Hugfit) with
Aqua+.

3NUCLEUS®7 AQUA+ USER GUIDE
The Cochlear Nucleus Mic Lock-Stirrup is a retention
option to hold Aqua+ more securely behind your ear. The
stirrup connects to the base of Aqua+ and the Mic Lock tube
(when cut to size) passes under the ear lobe and connects to
the Aqua+ earhook.
The Nucleus Safety Line is a retention option to help prevent
accidental loss of your Aqua+ by securing it to your clothing
with a snap-lock clip.
Remotes, wireless accessories and compatible iOS devices can
be used with Aqua+, however they should be protected from
water and kept dry.
You may notice a difference in sound quality when using
Aqua+.
Testing shows Aqua+ can be used at depths of up to 3 metres
for up to 2 hours.
Testing shows Aqua+ can be re-used up to 50 times, but this
may vary depending on your particular use of it.
There have been no reported undesirable side effects from
using Aqua+.
For more information, refer to the Nucleus 7 Sound Processor
User Guide.

Warnings
• If your sound processor becomes warmer than usual,
remove it immediately and seek advice from your clinician.
Parents/caregivers: if your recipient indicates discomfort,
check if their sound processor is warmer than usual.
• Small parts (e.g. magnets, Safety Line) may be a choking or
strangulation hazard.
• The Aqua+ and sound processor should be protected
from excessive heat sources such as prolonged exposure
to bright sunlight. Before wearing the Aqua+ and sound
processor, check the surface to ensure it is not too hot to
wear without discomfort to skin.
• Exposure of the sound processor and Aqua+ to
temperatures above the operating range (+5° C – +40° C,
+41° F – +104° F) could lead to increased risk of sound
processor shutdown or malfunction due to overheating.

15NUCLEUS®7 AQUA+ USER GUIDE
• If you experience tightness or pain at the implant site, or
develop significant skin irritation, stop using your sound
processor and contact your clinician.
• If the coil magnet is too strong, pressure sores may
develop at the implant site. If this happens, or if you
experience any discomfort in this area, contact your
clinician.
• Store spare magnets safely and away from cards that may
have a magnetic strip (e.g. credit cards, bus tickets, etc).
• No modification of this equipment is allowed.
• Use only as intended.
• Report unexpected problems to your clinician.

16 NUCLEUS®7 AQUA+ USER GUIDE
Cautions

your usual coil.
• When connecting the coil cable, always push the plug
straight in; do not screw or twist the plug.
• Where possible, avoid pressing the processor button with
your fingernail as this can damage your Aqua+.
• If your Aqua+ appears damaged or worn, replace it with a
