21. 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
21.1 Hazard warnings
Your Virto M-312 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 14.
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).
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 if not securely attached, a cerumen stop can
remain in your ear canal when removing the hearing aid from
the ear. In the unlikely case that such part gets stuck in your
ear canal, it is strongly recommended to see a physician for
safe removal.
52
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).
53
The following is only applicable for persons with active
implantable medical devices (i.e. pacemakers, debrillators,
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.
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
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.
54 54
Virto M-312 only: 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.
Avoid strong physical impacts to the ear when wearing in-theear hearing aids. The stability of in-the-ear shells is designed
for normal use. A strong physical impact to the ear (e.g. during
sports) may cause the in-the-ear shell to break. This may lead
to perforation of the ear canal or ear drum.
After mechanical stress or shock to the hearing aid, please
ensure that the hearing aid shell 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.

21.2 Information on product safety
Never immerse your hearing aid in water! Protect it from
excessive moisture. Always remove your hearing aid before
showering, bathing, or swimming, as the hearing aid contains
sensitive electronic parts.
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.
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.
56
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.
57
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.
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 aect the hearing aids.
Do not use your hearing aid in areas where electronic
equipment is prohibited.
Do not kink or buckle the removal handle. Repeated stress to
the removal handle may cause it to break. In case of a broken
removal handle the battery door may exceptionally be used to
carefully pull the hearing aid out of the ear canal.
