Hybrid mode explained
Hybrid mode may benefit Cochlear implant recipients who
have some residual hearing, by providing amplified sound
(like a hearing aid).
In Hybrid mode, your Nucleus 7 Sound Processor delivers
two types of sound signals:
• the usual electric signals to the Cochlear implant
• extra acoustic signals to the Hybrid system.

Nucleus 7 Hybrid system
The Nucleus 7 Hybrid system is made up of:
• The Cochlear Hybrid Earhook–replaces your normal
earhook, and connects the Cochlear Hybrid Receiver to
your sound processor.
• The Cochlear Hybrid Receiver–a cable with a speaker
unit that fits in your ear. It has a replaceable wax filter.
• A dome–fits over the speaker unit to hold it in place
and protect your ear. It is disposable and has a built-in
wax filter.
CAUTIONS
• Your clinician will select the receiver and dome that you
should use. Do not substitute any other parts.
• Your clinician will attach and remove the receiver for you. Do
not attempt to do this yourself.

Care for your Hybrid system
NOTE
Your Nucleus 7 Hybrid system is not compatible with any parts
that can be used with Freedom, CP800 Series or CP900 Series
Sound Processors (e.g. domes, earmoulds, receivers or
earhook).
CAUTIONS
• Handle and store the Hybrid system very carefully.
• Do not drop the Hybrid system.
The Nucleus 7 Hybrid system provides the benefit of two
wax filters:
1. An in-built wax filter in the disposable dome.
2. A replaceable wax filter fitted in the receiver’s speaker
unit.
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.

Change the dome
1. Pull the dome off,
using your
fingernails if
necessary, and

the filter from side
to side and remove
it from the speaker
unit.
