Introduction

. Introduction
This user manual provides information and instructions regarding the MED-EL Cochlear
Implant (CI) System with the SONNET audio processor (Me). It includes descriptions of
available parts, wearing options, and accessories for the SONNET, as well as instructions for
troubleshooting and proper care of the external cochlear implant equipment.
Your MED-EL Cochlear Implant System consists of the Mi SYNCHRONY (hereafter referred
to as SYNCHRONY), Mi MED-EL CONCERT (hereafter referred to as MED-EL CONCERT),
PULSAR, SONATA or C+ implants, the external SONNET audio processor (including
FineTuner and D Coil), the external components and accessories, and any external hardware
and software used by your audiologist.
This symbol indicates information that is particularly relevant for parents of implanted
children.
IMPORTANT
You are the operator of your / your child‘s SONNET audio processor, therefore we recommend
that you read this manual in its entirety. Do not perform any maintenance activities other
than those described in this manual (e.g. changing batteries). When performing these
maintenance activities, always remove the audio processor from the ear.
The adjustment to a cochlear implant and adequate tting of the device are gradual processes
that occur over time. It is important to remember that your ability to hear with your new
MED-EL system may take a little time while you become accustomed to this new method
of hearing. You may choose to work with an aural rehabilitation specialist or other clinician
to help you maximize your communication skills using the device. The audio processor can
be activated for the rst time after the surgical incision has completely healed and any
remaining swelling has gone away. The implant cannot provide any sound information until
the audio processor has been programmed by your audiologist, turned on, and placed on the
head over the implant.
After your initial tting, you will need to return to your CI center on a regular basis for
reprogramming. Frequent reprogramming may be required during the rst year of implant
use. This is normal and necessary, and it reects a learning process that occurs as you
become more and more accustomed to stimulation through the implant. As more time
passes, you will likely nd that you may require fewer and fewer sessions. Most patients
continue to require occasional adjustments for as long as they use their implant.
Please contact your CI center or MED-EL with any additional questions you may have.

INTENDED USE
The SONNET audio processor is an external part of the MED-EL Cochlear Implant System.
The MED-EL Cochlear Implant System is intended to evoke auditory sensation via electrical
stimulation of the auditory pathways for severely to profoundly hearing impaired individuals
who obtain little or no benet from acoustic amplication in the best aided condition.
INDICATIONS
The SONNET audio processor is an external component of the MED-EL Cochlear Implant
System and is indicated for use on patients who have been implanted with SYNCHRONY,
MED-EL CONCERT, PULSAR, SONATA or C+ cochlear implants. The MED-EL Cochlear
Implant System is indicated for:
• Adults eighteen () years of age or older who have bilateral, sensorineural hearing
impairment and obtain limited benefit from appropriately fitted binaural hearing aids.
These individuals typically demonstrate bilateral severe to profound sensorineural
hearing loss determined by a pure tone average of  dB or greater at  Hz,  Hz,
and Hz. Limited benefit from amplification is defined by test scores of % correct
or less in the best aided listening condition on CD recorded tests of open-set sentence
recognition (Hearing In Noise Test [HINT] sentences).
• Children aged twelve () months to seventeen () years eleven () months must
demonstrate a profound, bilateral sensorineural hearing loss with thresholds of dB
or greater at  Hz and above. In younger children, little or no benefit is defined
by lack of progress in the development of simple auditory skills in conjunction with
appropriate amplification and participation in intensive aural habilitation over a three
() to six () month period. In older children, lack of aided benefit is defined as < %
correct on the Multi-syllabic Lexical Neighborhood Test (MLNT) or Lexical Neighborhood
Test (LNT), depending upon the child‘s cognitive ability and linguistic skills. A three () to
six () month hearing aid trial is required for children without previous experience with
hearing aids. Radiological evidence of cochlear ossification may justify a shorter trial with
amplification.
The SONNET is intended to be used every day during a patient´s waking hours.

Fig.  The MED-EL cochlear implants
The external parts include the SONNET audio processor and the audio processor accessories.
In its basic conguration, the SONNET audio processor consists of the control unit with
the earhook attached, the battery pack (consisting of frame and cover), the coil and the
coil cable. A separate device called FineTuner facilitates access to various audio processor
functions.
The coil is held in place by magnetic attraction to the implant.
The audio processor uses batteries that provide sufcient power for both the external and
the implanted electronics. The implanted part does not contain batteries.

ON/OFF SWITCH
The battery pack cover functions as an ON/OFF switch.
You may select the following positions:
Battery pack cover pulled back: OFF
Battery pack cover completely moved over the frame: ON
IMPORTANT
When trying to pull back the battery pack cover, make sure that the battery pack cover lock
is in the unlocked position as shown in Fig. -. When it is not in the unlocked position, use
the screwdriver provided with your SONNET kit to turn it counter-clockwise into the unlocked
position.
There is no need to completely remove the battery pack cover to switch off the SONNET. It is
sufcient to pull it back to a position where you can see the whole labelling on the control
unit (see Fig. ).

In young children, the battery pack cover lock must always be turned clockwise into
the locked position (see Fig. -), once the cover has been moved completely over the
frame, to prevent the child from disassembling the audio processor.
To activate your CI system, switch on the SONNET and place the control unit and battery pack,
behind the ear and the coil, with the at side to the head, over the site of the implant (see
Fig. ). As soon as the coil is approximately over the implant, it is automatically positioned
correctly by attraction to the implant magnet.
An ear mold may help keep the processor in position on the ear. Contact your CI
center or audiologist for assistance.
Fig.  SONNET behind the ear and coil over the site of the implant
In the OFF position, the audio processor is turned off. No current is drawn in this position.
Make sure to pull back the battery pack cover of your audio processor when it is not in use,
as this prolongs the lifetime of the batteries (see also chapter , Care and maintenance).
If the processor is turned off (i.e., the battery pack cover pulled back), make sure that
young children do not have access to the audio processor to prevent disassembling
the device.
The SONNET audio processor has an integrated telephone coil (telecoil). The telecoil picks up
magnetic sound signals coming from telephone receivers or loop systems, which are installed
in some public buildings, and converts them into audible signals.


To use the telecoil, proceed as follows:
• Activate the telecoil by pressing the key T(only signals picked up by the telecoil will be
audible) or MT (signals picked up by the microphone and the telecoil will be audible) on
your FineTuner, as described in chapter , SONNET audio processor, FineTuner, FineTuner
controls.
• When you are using a telephone, position the telephone so that its earpiece is centered
over the SONNET control unit. Move the telephone slightly up or down as necessary to
optimize the signal quality.
• When you are in an environment with a loop system, try to find a spot where the signal
quality is best for you.
• To deactivate the telecoil when you do not need it anymore, press the key MT on your
FineTuner, as described in chapter , SONNET audio processor, FineTuner, FineTuner
controls.
When you switch on the audio processor, the microphone is active, even if you had the
telecoil selected before you switched off the audio processor. When the telecoil is active,
you may hear buzzing sounds when operating a FineTuner key. The buzzing is normal and
indicates that a command is being sent. To reduce interference with various electronic and
electrical equipment when the telecoil is active, we recommend you reduce audio sensitivity
(see chapter , SONNET audio processor, FineTuner, FineTuner controls).

FINETUNER
Your audiologist will program your SONNET audio processor to suit your needs. The FineTuner
is provided to help you optimally use your audio processor in different listening situations.
The SONNET audio processor itself has only an ON/OFF switch. All other functions are
accessed with a separate device, the FineTuner, which transmits commands to your SONNET
audio processor via a radio frequency (RF) link. Its ergonomic design and larger size keys
facilitate changing the settings of your SONNET audio processor.
Keeping the FineTuner out of the reach of children prevents them from inadvertently
changing the settings of their audio processor.
The FineTuner is not necessary for the function of your audio processor. When switched on,
the audio processor activates the same program, volume and audio sensitivity setting it had
when it was switched off.
The FineTuner is congured for a specic (or target) audio processor, and only the target
audio processor will execute the desired command when a certain key is pressed on the
FineTuner. The typical maximum operating distance between the FineTuner and the audio
processor is approximately cm (. ft.). This range could be decreased close to electronic
and electrical equipment even if this equipment complies with all applicable electromagnetic
emission requirements.

How to congure your FineTuner
The FineTuner is congured for your audio processor and cannot be used by another cochlear
implant user. Your audiologist or clinical staff will congure the FineTuner to your needs.
Sometimes it may be necessary that you synchronize your FineTuner and audio processor
(e.g. if you purchase a backup FineTuner). To do so, rst switch off your audio processor and
place the coil of the audio processor on the keyboard of the FineTuner (approximately over
key MT). Then switch on your audio processor. The audio processor and FineTuner will be
synchronized automatically. Successful synchronization is indicated by a short blinking signal
of the two amber indicator lights on your FineTuner. It is only necessary to re-synchronize
the processor to the FineTuner if you replace the processor or FineTuner.
For bilaterally implanted users
One FineTuner can be congured for use with one audio processor per ear. If you want to use
your FineTuner for both audio processor systems, your audiologist or clinical engineer can
congure one FineTuner to communicate with both the left and right audio processors. Once
your audio processors are programmed correctly, the synchronization procedure described
above should be performed with both audio processors.

To activate the keyboard lock feature of your FineTuner, press the  key for more than
 seconds to enter the program mode (the red and both amber indicator lights on your
FineTuner will start blinking alternately, indicating that you have successfully entered the
FineTuner’s program mode) and, then, the key to activate the automatic keyboard lock
(the FineTuner will conrm successful activation of the automatic keyboard lock by a short
blinking signal of the two amber indicator lights).
To deactivate the automatic keyboard lock, press the  key twice to unlock the keyboard
for  seconds, then hold it down for more than  seconds to enter the program mode. Press
the key to deactivate the keyboard lock. As described above, the FineTuner will conrm
successful deactivation of the automatic keyboard lock by a short blinking signal of the two
amber indicator lights.
To activate a certain function while the keyboard lock is active, press the desired function
key twice. The rst click temporarily unlocks the keyboard; the second click executes the
command. After  seconds without pressing another key, the keyboard lock is active again.
Battery low warning: If you press a key and see the red indicator light on your FineTuner
ashing  times, then the voltage level of your FineTuner is critically low (see also chapter ,
Care and maintenance, Batteries, Changing the battery of your FineTuner).
Transmitter time-out: The FineTuner stops transmitting after  seconds to save energy, even
if the key is still pressed.
Your FineTuner does not have an ON/OFF switch.
Three indicator lights with different colors ( amber,  red) indicate various conditions of the
FineTuner. For a detailed description of their function see chapter , Troubleshooting. The
FineTuner does not affect connected assistive listening devices.

BATTERY PACK
The SONNET battery pack (product code Ma) consists of the battery pack frame,
holding two hearing aid batteries, and the battery pack cover. The battery pack cover, which
also functions as the ON/OFF switch of the SONNET (see Fig.  and ) slides over the battery
pack frame. This conguration allows the entire audio processor to be worn on the ear.
Changing the batteries is described in chapter , Care and maintenance, Batteries, Changing
the batteries of your SONNET audio processor.
To remove the battery pack from the control unit (e.g. to connect a MAX programming
cable instead), proceed as follows:
. Make sure that the battery pack cover lock is in the unlocked position, as shown in
Fig. –. When it is not in the unlocked position, use the screwdriver provided with your
SONNET kit to turn it counter-clockwise into the unlocked position.
. Pull back and completely remove the battery pack cover.
. Press the release lever () on the battery pack frame as shown in Fig. –, and separate
battery pack frame and control unit ().
To attach the battery pack to the control unit, proceed as follows:
. Insert the rib on the control unit into the matching groove of the battery pack frame (),
as shown in Fig. -.
. Push the opposite end of the battery pack frame onto the control unit () until the
release lever engages.
. Make sure that the battery pack cover lock is in the unlocked position as shown in
Fig. –. When it is not in the unlocked position, use the screwdriver provided with your
SONNET kit to turn it counter-clockwise into the unlocked position.
. Slide the battery pack cover completely over the battery pack frame to switch on the
SONNET (see Fig. ). Mind the correct orientation of the battery pack cover when sliding
it over the frame, and do not use excessive force. The orientation is correct when the air
inlets () on the battery pack cover are on the same side as the coil cable socket in the
control unit (see Fig. -).
In young children, the battery pack cover lock must always be turned clockwise into
the locked position (see Fig. -), once the cover has been moved completely over the
frame, to prevent the child from disassembling the audio processor.

COIL
The coil connects the SONNET audio processor with the implant. It sends both energy and the
coded audio signal through the skin to the implant. A small magnet is located in the center of
the coil to hold it in place on the head over the implant. The magnet can be changed to adjust
the magnet strength to your needs. The magnet strength chosen should be appropriate for
the individual patient. Strong magnets are not recommended for patients with thin skin aps
(e.g. young children or very slim patients), as excessive magnetic attraction could potentially
increase the likelihood of skin irritation.
The SONNET audio processor can be used with the MED-EL D Coil, it cannot be used with the
previous generation COMT+/COMT+ P coils.

IMPORTANT
Depending on the type of implant, two variants of magnets (i.e. magnet inserts) are available
for the D Coil. These two variants differ in magnet polarisation. The type of implant is stated
on your Patient Identication Card.
For patients implanted with a SYNCHRONY implant, the magnet insert
must contain triangles as shown in Fig. .
For patients implanted with any other type of implant (MED-EL CONCERT,
SONATA, etc. ), the magnet insert must contain circles as shown in
Fig. .
It is essential that, based on the type of implant, the correct variant of magnet is used! If
the wrong variant of magnet is inserted, the coil may still be held in place over the implant.
However, due to different polarisation of the magnets, a slight dislocation between the
implant and coil will occur which may result in improper communication between implant
and coil.
