Tip
Time saving hint.
Caution (no harm)
Special care to be taken to ensure safety and effectiveness.
Could cause damage to equipment.
This guide is for recipients of the Cochlear™
Nucleus®Hybrid L24 Cochlear Implant. It
providesinformation about using an acoustic
component with your sound procesor for
Hybrid Hearing. You can also choose a
Cochlear Nucleus CR210 Remote Control or
CR230 Remote Assistant to control
your processor. For more about remotes,
please consult your remote user guide.
People with certain types of hearing loss can wear the processor in
Hybrid mode by adding an acoustic component. The acoustic component
sends amplified acoustic sound into the ear canal.
A number of tools and accessories are supplied with your sound processor.
NOTE
Please refer to the booklet Important
Information: Warnings, Precautions and
Electromagnetic Compatibility for important
information that applies to cochlear
implant systems.

When removing your coil and processor,
remove your dome or earmould as
instructed by your clinician.
4
TIP
Always use the removal cord
(if present) when taking the
earmould out of your ear.

7COCHLEAR NUCLEUS 6 • HYBRID HEARING SUPPLEMENT
Remove your acoustic component
Wear your processor without the acoustic component by
replacing it with a standard earhook. Talk to your clinician
before replacing:
Locate the opening under the earhook.

Care

13COCHLEAR NUCLEUS 6 • HYBRID HEARING SUPPLEMENT
Care for your acoustic component
The acoustic component is used only by people who are set up to use their
processor in Hybrid mode.
If you use Power or Plus Domes
Every day
• Check the dome and its filter. Change the dome whenever its filter
is clogged with wax, or whenever the dome is dirty, discoloured or
losing shape.
• When changing the dome, also check the wax filter in the speaker unit.
Change the speaker unit filter whenever it is clogged with wax or if the
sound from the speaker unit does not sound normal.
If you use RITE Power or Power Micro Moulds
Every day
• Clean the earmould and speaker unit cable with the supplied brush
or a soft dry cloth. Wipe any traces of wax away from the opening
of the vent.
• Check if the vent is clogged, and use the supplied vent cleaner to remove
wax as needed. Do NOT use the vent cleaner to clean any other part.
• Check the wax filter and change whenever it is clogged with wax or if the
sound from the speaker unit does not sound normal.
CAUTION
Handle and store the acoustic component
very carefully. Do not drop the acoustic
component. Do not twist the speaker unit cable.
Keep the speaker unit away from the coil magnet.
NOTE
Power Micro Moulds can use Cochlear
EAC200 Series WaxStop Wax Management
System filters ONLY.
RITE Power Moulds can use either Cochlear
EAC200 Series NoWax Wax Management
System or WaxStop filters.

14
Replace Power Domes
Replace Plus Domes
Follow the directions for replacing Power Domes and add the following step:
Pull the dome off using your fingernails
if necessary and discard.
1
Push the new dome directly onto the
speaker unit.
2
Click it securely into place.
3
When fitting a Plus Dome, the outer
sleeve should face down.
4

15COCHLEAR NUCLEUS 6 • HYBRID HEARING SUPPLEMENT
Replace a WaxStop filter
Power and Plus Domes must be worn with a WaxStop filter in the speaker unit.
Remove a WaxStop tool from its shell.
One end of the tool has a new filter and
the other has a removal tool.
1
Insert the removal tool into the existing
wax filter.
2

16
Pull the used filter out slowly, keeping
the tool straight.
3

Warnings
General
• No modification of this equipment
is allowed.
• Removable parts of the system
(e.g. Snugfit, Mic Lock) can be lost or
may be a choking hazard.
• Sound processor covers and coil covers
may not be suitable for children.
Removable parts can be lost or may
be a choking hazard.
• Keep chemicals from dry aid kits
away from small children. Swallowing
this material can cause serious
internal injuries.
Processors and parts
• Remove the processor and coil
immediately if there is any discomfort or
pain (e.g. if device becomes hot, or sound
is uncomfortably loud) and inform
clinician. Carer must routinely check the
device for signs of overheating and for
signs of discomfort or pressure sores at
the coil site.
• Remove the monitor earphones
immediately if the sound level is
uncomfortably loud and inform
your clinician.
• If the coil magnet is too strong or is in
contact with the skin, pressure sores may
develop at the coil site. If this happens, or
if you experience any discomfort in this
area, contact your clinician.
• Do not push the volume too high for
comfort in case a loud noise
occurs nearby.
• Do not place the device or accessories
inside any part of your body
(e.g. nose, mouth).

18
Acoustic component
• Refit and replace domes regularly to
ensure optimal fitting and retention.
Consult your clinician for advice on
acoustic component misfits or signs
of discomfort.
• Remove acoustic component if there
is any discomfort or pain (e.g. sound
level is uncomfortably loud) and inform
your clinician.
• Contact your clinician for advice on
choosing the most suitable acoustic
component for children.
• Do not allow children to replace an
acoustic component without adult
supervision.
• Keep all parts of the acoustic component
out of reach of children. Removable parts
(e.g. Power/Plus domes and wax
management systems) can be lost or
may be a choking hazard.
• If the Power Dome or Plus Dome is not
securely attached to your acoustic
component, it could fall off in your ear
canal. If this happens, see your medical
practitioner.
• Carers should routinely check that the
acoustic component is working at a
comfortable volume level. See your
clinician if the sound level ever becomes
uncomfortable.
