19. Important safety information

Please read the information on the following pages before
using your hearing aid.

A hearing aid will not restore normal hearing and will not
prevent or improve a hearing impairment resulting from
organic conditions. Infrequent use of a hearing aid does not
permit a user to attain full benet from it. The use of a
hearing aid is only part of hearing habilitation and may
need to be supplemented by auditory training and
instruction in lipreading.

The hearing aid is suitable for the home healthcare
environment and due to their portability it may happen that
it is used in professional healthcare facility environment like
physician oces, dental oces etc.

48

19.1 Hazard warnings

Your hearing aids operate
between 2.4 GHz–2.48 GHz
frequency range. When
ying please check if ight
operator requires devices
to be switched into ight
mode, see chapter 12.

The intended use of
hearing aids is to amplify
and transmit sound to the
ears and hereby
compensate for impaired
hearing. The hearing aids
(specially programmed for
each hearing loss) must
only be used by the
intended person. They
should not be used by any
other person as they could
damage hearing.

Changes or modications
to the hearing aid that
were not explicitly
approved by Sonova AG
are not permitted. Such
changes may damage your
ear or the hearing aid.

Do not use the hearing
aids in explosive areas
(mines or industrial areas
with danger of explosions,
oxygen rich environments
or areas where ammable
anesthetics are handled).

Hearing aid batteries are
toxic if they are swallowed!
Keep out of the reach of
children, individuals with

49

cognitive impairment, and
pets. If batteries are
swallowed, consult your
physician immediately!

If you feel pain in or
behind your ear, if it is
inamed or if skin
irritation and accelerated
accumulations of earwax
occur, please check with
your hearing care
professional or physician.

In very rare cases, the
dome can remain in your
ear canal when removing
the hearing tube from the
ear. In the unlikely case
that the dome does get
stuck in your ear canal, it is
strongly recommended to
see a physician for safe

50

removal. To prevent
pushing the dome towards
the eardrum, never try to
re-insert the speaker into
the ear canal.

Hearing programs in the
directional microphone
mode reduce background
noises. Please be aware
that warning signals or
noises coming from
behind, e. g. cars, are
partially or entirely
suppressed.

This hearing aid is not for
children below 36 months.
The usage of this device by
children and individuals
with cognitive impairment
should be supervised at all
times to ensure their

safety. The hearing aid is a
small device and contains
small parts. Do not leave
children and individuals
with cognitive impairment
unsupervised with this
hearing aid. If swallowed,
consult a physician or
hospital immediately as the
hearing aid or its parts can
cause choking!

Do not make a wire
connection from your
hearing aid to any external
audio sources like radio
etc. That could cause
injuries on your body
(electric shock).

The following is only
applicable for persons with
active implantable medical

devices (i.e. pacemakers,
debrillators, etc.):

Keep the wireless hearing

aid at least 15 cm

(6 inches) away from the
active implant. If you
experience any interference,
do not use the wireless
hearing aids and contact
the manufacturer of the
active implant. Please, note
that interference can also
be caused by power lines,
electrostatic discharge,
airport metal detectors etc.

Keep magnets (i.e. battery

handling tool, EasyPhone

magnet, etc.) at least
15 cm (6 inches) away
from the active implant.

51

If using a Phonak

wireless accessory,
consult the chapter
“Important safety
information” in your
wireless accessory
user guide.

Use of accessories,
transducers and cables
other than those
specied or provided by
the manufacturer of
this equipment could
result in increased
electromagnetic
emissions or decreased
electromagnetic
immunity of this
equipment and result
in improper operation.

52

Portable RF
communications
equipment (including
peripherals such as
antenna cables and
external antennas) should
be used no closer than
30 cm (12 inches) to any
part of the hearing aids,
including cables specied
by the manufacturer.
Otherwise, degradation of
the performance of this
equipment could result.

Hearing aids should not be
tted with domes / wax
protection systems when
used by clients with
perforated eardrums,
inamed ear canals or
otherwise exposed middle

ear cavities. In these
cases, we recommend
the use of a custom
earpiece. In the unlikely
case that any part of
this product should
remain in the ear
canal, it is strongly
recommended to see
a medical specialist for
safe removal.

Avoid strong physical
impacts to the ear when
wearing a hearing aid
with customized
earpiece. The stability of
customized earpieces is
designed for normal
use. A strong physical
impact to the ear (e.g.
during sports) may

cause the customized
earpiece to break. This may
lead to perforation of the
ear canal or eardrum.

After mechanical stress or
shock to the customized
earpiece, please ensure
that it is intact before
placing it in the ear.

Use of this equipment
adjacent to or stacked with
other equipment should be
avoided because it could
result in improper
operation. If such use is
necessary, this equipment
and the other equipment
should be observed to
verify that they are
operating normally.

19.2 Information on product safety

These hearing aids are water

resistant and not
waterproof. They are
designed to withstand
normal activities and
occasional accidental
exposure to extreme
conditions. Never immerse
your hearing aid in water!
These hearing aids are not
specically designed for
extended periods of water
submersion on a continual
basis, that is worn in
activities such as swimming
or bathing. Always remove
your hearing aid before
these activities, as the
hearing aid contains
sensitive electronic parts.

54

54

Never wash the

microphone inputs. Doing
so could cause it to lose its
special acoustic features.

Protect your hearing aid

from heat (never leave near
a window or in the car).
Never use a microwave or
other heating devices to
dry your hearing aid. Ask
your hearing care
professional about suitable
drying methods.

The dome should be

changed every three
months or when it
becomes sti or brittle.
This is to prevent the dome
from detaching from the
tube spout during insertion
into or removal from
the ear.

When you are not using

your hearing aid, leave the
battery door open so that
any moisture can
evaporate. Make sure that
you always completely dry
your hearing aid after use.
Store the hearing aid in a
safe, dry and clean place.

Do not drop your hearing

aid! Dropping onto a hard
surface can damage your
hearing aid.

Always use new batteries

for your hearing aid. In
case a battery is leaking,
replace it immediately with
a new one to avoid any
skin irritation. You can
return used batteries
to your hearing care
professional.

The batteries used in these

hearing aids should not
exceed 1.5 Volts. Please do
not use silver-zinc or Li-ion
(lithium-ion) rechargeable
batteries as these may
cause severe damage to

55

your hearing aids. The table
in chapter 5 explains
exactly which type of
battery your particular
hearing aids require.

Remove the battery if

you are not using your
hearing aid for a long
period of time.

Special medical or dental

examination including
radiation described below,
may adversely aect the
correct functioning of your
hearing aids. Remove and
keep them outside the
examination room/area
before undergoing:

56

Medical or dental

examination with X-ray
(also CT scan).

Medical examinations with

MRI/NMRI scans,
generating magnetic elds.
Hearing aids don’t need to
be removed when passing
security gates (airports
etc.). If X-ray is used at all,
it will be in very low doses,
and will not aect the
hearing aids.

Do not use your hearing

aid in areas where
electronic equipment
is prohibited.
