Safety Instructions
• Swallowing the batteries is harmful. Keep out of reach of children
or people with mental disabilities.
• Consult before using your hearing aids in zones in which electronic
or wireless devices are restricted (aeroplanes, for example).
• Do not under any circumstances use your hearing aids in areas
with medical equipment (X-ray, high-frequency, MRI or shortwave
therapy).
• Do not use the hearing aids in areas exposed to the danger of
explosion or an oxygen-rich atmosphere!
• Stay away from strong electromagnetic fields.
• Persons with pacemakers or magnetic valves should keep their
hearing aids at least 15 cm away; if interference is detected, refer to
the implant manufacturer's safety instructions. Metal detectors or
alarms may cause interference or create unexpected sounds.
• Your hearing aid can generate sound output levels in excess of
132 dB
SPL.
A hearing health professional should take special care when adapting
this hearing aid, as there may be a risk of damaging the user's residual
hearing.
WARNING!
• Protect your hearing aids from moisture, heat sources.
• Do not use your hearing aids if you are going to shower, bathe or
spray your hair.
• Do not let your hearing aids to suffer hard impacts.
• Never use a microwave or other heat-emitting devices to dry your
hearing aids.

Intended Purpose
The intended purpose of the hearing aids is to selectively amplify
sound and transmit it to the ear to compensate for the hearing of
hearing impaired people.
Its use is not intended for children or people with mental disabilities.
• Your hearing aid is intended to compensate for severe to profound
hearing loss (transmissive, mixed or neurosensory).
The prescription and adaptation of the hearing aids must be performed
by a hearing health professional, who will perform the programming
and specific adjustment for hearing loss and the morphology of the
user in a completely personalized manner. Therefore, using hearing
aids not prescribed by a professional or adapted for another person
can damage your hearing.
Operation Principles
See Figure 3
BTE (Behind the Ear) is a type of anatomical hearing aids housed
behind the ear. They are powered by a battery and typically intended
to cover severe or profound hearing loss. All mechanical and
electronic components are contained in an ergonomic box. They
are adapted to the wearer's ear by means of custom earmolds or
adapters from which a conductive tube comes out, attached to the
tube of the hearing aid or to the thin tube.
Earmolds and conductive tube: responsible for conducting sound
and allowing the device to be adapted to the ear using a custom
earmold or adapter.
Microphone: gathers sound and converts it into an electric signal.
Amplifier: digital processor, which collects the signal and adapts it to
the parameters entered for each loss.
Receiver: converts the electrical signal into sound and transmits it,
already amplified, to the user's ear.
Telecoil: captures variations in magnetic fields and transforms them
into electric signals.
