General Warnings and Safety
Guidelines
Hearing instruments and batteries can be danger-
ous if swallowed or improperly used. Such actions
can result in severe injury, permanent hearing loss
or even fatality.
Familiarize yourself completely with the following
general warnings before using your hearing
instruments.
·Hearing instruments should be used only as
directed and adjusted by your trained hearing
care professional. Misuse or improper adjust-
ments can result in sudden and permanent
hearing loss.
·Hearing instruments will not restore normal
hearing or prevent hearing loss resulting from
organic conditions.
·Never allow others to wear your hearing instru-
ments, because they are adjusted for your
hearing requirements and may permanently
damage another person’s hearing.
8
·A slap to your ear while wearing the instrument
could be harmful. Avoid wearing your hearing
instrument while playing contact sports (e.g.
rugby, football etc.).
·Be aware that use of a hearing instrument may
cause excess ear wax to build up in the ear canal
which may require removal by a trained medical
professional.
·In rare cases, a hearing instrument or earmold
may cause a discharge from the ear or allergic
reaction. See a physician immediately if these
conditions occur.
·An earmold is a custom-made product. If you
experience discomfort or irritation of your ear,
please see your hearing care professional
immediately for modication of the earmold.
·Hearing instruments, their parts and batteries
should be kept out of reach of infants, children
and anyone who might swallow these items or
otherwise cause themselves injury.
·Discard batteries and keep them out of sight
of infants, small children, persons of mental
incapacity or pets.
9
·Clean your hearing instruments and their parts
on a regular basis as recommended. Micro-
organ isms from unclean instruments may cause
skin irritations.
·Be careful with leaking battery liquid, as it is a
hazardous substance.
·Never try to recharge non-rechargeable batteries.
·Never change the battery or adjust the controls
of the hearing instrument in front of infants, small
children and persons of mental incapacity.
·Never put your hearing instrument or batteries in
your mouth, they could easily be swallowed.
·Keep batteries away from medications. Batteries
are easily mistaken for pills.
·In case a battery or hearing instrument is
swallowed, see a doctor immediately.
·Be aware of the possibility that your instruments
may stop functioning without notice. Keep this in
mind while you circulate in trafc or otherwise
depend on warning sounds.
·Trafc or other warning sounds may also be
reduced in level by a directional microphone
when these sounds are coming from behind you.
·Never insert cleaning tools into the sound
outlet or microphone inlet. This could damage
the hearing instruments.
10
·Do not expose hearing instruments to extreme
heat by leaving them in the car, near a radiator,
etc.
·Avoid exposing your instruments to moisture
i.e. steambaths, showers, heavy rain, etc.
·Never attempt to dry your instruments with
a hair dryer, microwave oven, etc.
·Remove your instruments before applying
aftershave, hairspray, oils, perfume, mosquito
repellent, lotions, etc. Allow the product to
dry before wearing your instruments.
·Protect your instruments by keeping them in
the case when you are not wearing them.

Healthy ears produce a waxy substance that can
block your speaker. Please follow these cleaning
instructions to prevent wax build-up and ensure
optimal performance of your instruments.
Every night
·Check your hearing instrument for ear wax and
wipe it clean with a cloth or tissue.
·Clean the speaker unit and dome with a cloth or
tissue. If you nd ear wax remaining on the
dome, exchange it. When the dome comes off,
never put it back onto the speaker, but replace it
with a new one.
·Open the battery drawer fully to allow air to
circulate.
·A dry storage kit is recommended to remove
any moisture that may have accumulated in the
instrument. Always remove zinc-air batteries
before drying your hearing instrument with a
drying kit. Drying out zinc-air batteries shortens
their lifetime.
Instrument Care
31
General care instructions
Treat your hearing instrument like any other
delicate electronic device (check the safety
guidelines on page 7) and make sure that the
instrument and the speaker do not get in contact
with moisture or water.
– Always clean and dry your hands thoroughly
before manipulating the instrument.
– Do not use your hearing instrument without a
dome or mold.
– Do not pull the speaker off the hearing instru-
ment. Should the speaker detach from the
instrument, ask your hearing care professional
for support.
– Never mount a used dome on the speaker.
32
Exchanging the dome
The dome should be changed regularly. The
frequency of dome changes will depend on how
fast ear wax accumulates on the dome. Inspect
your instrument’s dome for yellowing, hardening
and cracks. In the case of these changes, consider
replacing your dome or contacting your hearing
care professional.
Spare domes may be obtained from your hearing
care professional.
·Clean your hands thoroughly before replacing the
dome. Never change the dome with wet or dirty
ngers.
·Push the new dome as far as possible onto the
speaker.
·Make sure the dome is pushed rmly onto the
speaker.
Warning
The hands must be clean and dry before
replacing the dome. Never remount a used
dome on the speaker. A remounted dome is
more likely to fall off in the ear canal.
33
1) Hold the end of the dome
between your ngers and
pull it off.
2) Take a fresh dome
out of the package.
3) Place the new dome
on the speaker so it
ts securely.
Exchanging the dome
34
Cleaning the Micro and Power Mold
Clean your Micro/Power Mold after every use by
wiping it with a clean dry cloth. In most cases,
there is a hole through the Micro/Power Mold
(below the speaker unit). This is the vent. If the
vent is plugged with wax, insert the cleaning tool
(supplied) from the opposite end (nearest the
speaker wire), and push through to remove the
wax.
Replace the wax protection (WaxStop)
whenever needed following this procedure:
1) Take the stick with the new WaxStop on it (1).
On the opposite end is a removal plug for the
used WaxStop (2).

Hearing instruments do not restore perfect
hearing. They make sounds louder and help you to
make the most of the hearing that you have. While
some immediate benet is usually noticed, it often
takes several weeks for your brain to adapt to your
new instruments.
The following tips will help you learn to use your
hearing instruments. If you have trouble adjusting
to them, consult your hearing care professional.
Getting started
·Wear your instruments at home in a quiet
environment. Have a conversation with one
person or listen to a news program on TV.
·You will benet most if you wear your instru-
ments all day long. Increase the time each
day, until you are comfortable wearing them
for several hours at a time.
Using your Hearing Instruments
37
· You may notice that your own voice sounds
louder. If the voices of others are at a comfort-
able level, try speaking at a lower volume.
·Sounds like footsteps, chirping birds, rustling
paper, etc. may seem quite loud at rst because
you probably haven’t heard them for a while.
They will soon fade to the background.
Dining out
· Start with a quiet restaurant (no music or
entertainment).
·Request a table away from the kitchen and other
noisy areas.
·Conversation will be easier in a smaller group.
In the car
·Sit with your better ear towards the center of the
car, if possible.
·Turn off the radio.
·Keep the windows closed to minimize trafc,
road and wind noise.
38
Attending theatre, concerts, lectures, etc.
·Try to sit with your better ear closer to the sound
source, if possible.
·Become familiar with the program in advance to
make it easier to follow.
· Inquire if a loop is available. If not, sit towards
the front
· If your hearing is similar in both ears, sit in
the middle
At work
·Inform your co-workers about your hearing loss
and teach them to talk clearly. Keep eye contact
when conversing.
· Focus on the person nearest to you.
·If you hear only part of a conversation, repeat
what you have heard and ask for any missing
information.
At home
· Always use your hearing instruments.
· Inform family and friends about your situation.
· Teach your family to talk clearly and keep eye
contact when conversing.
· Teach your family how to involve you in
conversations.
· Avoid background noise.
39
Hearing on the telephone
·Hold the receiver close to the microphone inlet of
your hearing instrument. If this causes whistling,
move the receiver away a small distance.
·If voices over the telephone are too soft or
background noise is a problem, use the telecoil
(be aware that not all phones are telecoil
compatible).
·When using the telecoil, hold the phone behind
the ear, next to your hearing instrument for
better reception.
·Mobile phones may cause interference with the
telecoil. In this case, the microphone mode will
give a better result.
·Before purchasing a mobile phone, test it with
your hearing instrument.
·People with a greater degree of hearing loss may
need a volume control on the telephone.
40
Tips for Communicating with Hearing
Impaired People (Suggestions
for Family Members and Friends)
·Speech should be clear and distinct. Some
people may need to slow down a little but if
speech is too slow it can be even more difcult
to understand.
·Do not shout! Many people with hearing impair-
ment are very sensitive to loud sounds.
·If you are having difculty being understood,
rephrase the statement rather than repeating
the same words several times.
·Do not try to have a conversation from another
room or with your back turned. Talk face to face!
·Avoid eating, drinking or smoking while talking
and keep your hands away from your face.
·Minimize background noise – turn off the TV or
radio or move to a quiet area for conversation.
·Try to give some warning when the topic
changes during group conversations – it is much
easier to follow the conversation when you know
what is being discussed.
·Ensure there is good light on your face – the
eyes and ears work best together for maximum
understanding of speech.

Your hearing instruments contain electronic
components subject to the Directive 2002/96/EC
on waste electrical and electronic equipment.
Help to protect the environment by not disposing
of your hearing instruments or batteries with your
unsorted household waste. Please recycle your
hearing instruments and batteries according to
your local regulations or return them to your
hearing care professional for disposal.
Environmental Protection
46
All Bernafon Chronos hearing instrument models
comply with international standards concerning
electromagnetic compatibility. Due to the limited
size available on the instruments all relevant
approval markings are found in this document.
Electromagnetic interference
Your hearing instrument has been thoroughly
tested for electromagnetic interference. However,
some products may emit electromagnetic energy
causing unforeseen interference with hearing
instruments. Examples include induction cooking
appliances, shop alarm systems, mobile phones, fax
machines, personal computers, X-rays, CT scans,
etc.
Even though your hearing instruments are designed
to comply with the most stringent international
standards of electromagnetic compatibility, they
may emit electromagnetic energy that can cause
interference with other devices.
Product Approval, Markings
and Compliance
47
Your hearing instruments contain a radio
transmitter using short range magnetic induction
technology working at 3.84 MHz.
The magnetic eld strength of the transmitter
is < –42 dBμA/m @ 10 m.
The electromagnetic emission from the radio
system is well below international limits for human
exposure. By comparison, the electromagnetic
energy of the hearing instrument is lower than that
generated by household items such as halogen
lamps, computer monitors, dishwashers etc.
48
Cell Phone and Hearing Instrument
Compatibility
Some hearing instrument users have reported a
buzzing sound in their instruments when they are
using cell phones, indicating that the cell phone
and hearing instrument may not be compatible.
The compatibility of a particular hearing instrument
and cell phone can be predicted by adding the
rating for the hearing instrument immunity to
the rating for the cell phone emissions
(ANSI C63.19-2006 American National Standard
Methods of Measurement of Compatibility
between Wireless Communication Devices and
Hearing Aids).
For example, the sum of a hearing instrument with
a rating of 2 (M2/T2) and a telephone with a rating
of 3 (M3/T3) would result in a combined rating of 5.
According to the standard, any combined rating
that equals at least 5 would provide “normal use”;
a combined rating of 6 or greater would indicate
“excellent performance.”
49
The immunity of your Chronos hearing instrument
is at least M2/T2. The equipment performance
measurements, categories and system classica-
tions are based upon the best information available
but Bernafon cannot guarantee that all users will
be satised.
50
International Warranty
Your hearing instruments have a limited warranty,
covering defects in materials and workmanship.
This warranty covers the hearing instruments
themselves, but not accessories such as batteries,
tubing, earmolds, etc.
This warranty is void if a defect is the result
of misuse or mistreatment. The warranty is
also void if the hearing instruments have been
repaired by nonauthorized service personnel.
Please review the warranty with your hearing
care professional and make sure that your warranty
card is completed correctly.
