General Warnings and Safety Information
Hearing instruments and batteries can be dangerous
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 and safety guidelines before using
your hearing instruments.
Hazard Warnings
Warnings for Hearing Instrument Users
Never allow others to wear your hearing
instrument. It could permanently damage another
person’s hearing.

playing contact sports (e.g., rugby, football, etc.).
A slap to your ear while wearing a hearing
instrument could be harmful.

Keep your hearing instrument, parts, and batteries
out of the reach of infants, children, and anyone who
might swallow these items.
Discard batteries safely. Keep discarded
batteries out of sight of infants, small children,
vulnerable persons, and pets.
Clean your hearing instrument (including parts) on
a regular basis, as recommended by your hearing
care provider. Microorganisms from an
unclean hearing instrument may cause skin
irritations.
Be careful of leaking battery liquid. Battery liquid 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 vulnerable persons.
Be aware of the possibility that your hearing instrument may stop working without notice. Keep this in
mind when you depend on warning sounds
(e.g., when you are in traffic).
Be aware of the possibility that the directional
microphone in your hearing instrument may reduce
the volume of some warning sounds coming from
behind you.
Remove your hearing instrument before applying
aftershave, hairspray, oils, perfume, mosquito
repellent, lotions, etc. If your hearing instrument is
exposed to such a product, allow the product to dry
before you put your hearing instrument on.
Warnings to Hearing Care Provider
and patient
Special care should be taken when fitting and
using a hearing instrument with maximum sound
pressure capability in excess of 132 dB SPL
(IEC 60318-4) since there may be a risk of
impairing the remaining hearing of the patient.

Hearing Expectations
Set appropriate expectations
It is important that you have the right expectations
regarding your hearing instruments. Hearing
instruments can help you hear and understand better,
but they are not a cure for hearing loss.
People whose expectations are too high (“I thought
they would make my hearing normal”) are likely to be
disappointed and may give up.
Hearing instruments can:
· Help you hear and understand better in most
situations
· Allow you to participate more in group situations
and meetings
Hearing instruments cannot:
· Give you normal hearing
Hearing instruments may not:
· Let you hear very soft sounds
· Block ALL background noises – especially in noisy
situations. Even people without hearing loss
may have difficulty hearing in the presence of
background noise.

Be patient
Unlike with eyeglasses which correct your vision
as soon as you first put them on, with hearing
instruments you will need some time to adjust.
It may take several weeks or months to completely
adjust to your hearing instruments, so try to be patient.
Initially, try different listening situations, such as
one-on-one conversations with family and friends,
and conversations with two or three people at home
or in quiet settings. Also, try having conversations
in noisier places like parties, restaurants, meetings,
and outdoors.
Do not forget that some situations are simply too noisy
in general – even for people without hearing loss.
So, do not get discouraged.
