20. 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 benet 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.
Hearing aids are suitable for the home healthcare
environment and due to their portability it may happen that
they are used in professional healthcare facility
environments like physician oces, dental oces etc.
50
20.1 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 modications 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) or where electronic equipment is prohibited.
51
Hearing aid batteries are toxic if they are swallowed! Keep
out of the reach of children, individuals with cognitive
impairment, and pets. If batteries are swallowed, consult your
physician immediately!
If you feel pain in or behind your ear, if it is inamed 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 removal.
To prevent pushing the dome towards the eardrum, never try
to re-insert the tube 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.
52
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!
The following is only applicable for persons with active
implantable medical devices (i.e. pacemakers, debrillators, etc.):
Keep the hearing aid at least 15 cm (6 inches) away from
the active implant. If you experience any interference, do not
use the 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.
If using a Phonak wireless accessory, consult the chapter
“Important safety information” in your wireless accessory
user guide.
53
Use of accessories, transducers and cables other than those
specied 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.
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 specied by the manufacturer.
Otherwise, degradation of the performance of this equipment
could result.
Hearing aids should not be tted with domes /universal eartip
when used by clients with perforated eardrums, inamed 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
54
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.
55
20.2 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 specically 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.
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.
56
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.
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.
Do not drop your hearing aid! Dropping onto a hard surface
can damage your hearing aid.
If you are not using your hearing aid for a long period
of time, store it in a box with a drying capsule or in a well
ventilated location. This allows moisture to evaporate
from your hearing aid and prevents a potential impact on
its performance

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 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 aect the correct functioning
of your hearing aids. Remove and keep them outside the
examination room/area before undergoing:
Medical or dental examination with X-ray (also CT scan).
Medical examinations with MRI/NMRI scans, generating
magnetic elds.
