REQUIRED HEARING AID INFORMATION
The following additional information is provided in compliance
with U.S. Food and Drug Administration (FDA) regulations:
WARNING: People younger than 18 should go
to a doctor before using this.
People younger than 18 years old need specialized care, and
using this without a medical evaluation may worsen impairment
or disability. A hearing aid user who is younger than 18 should
have a recent medical evaluation from a doctor, preferably an
ear-nose-throat doctor (ENT). Before using this, a doctor should
determine that the use of a hearing aid is appropriate.
WARNING to Hearing Aid Dispenser:
You should advise a prospective hearing aid user to consult
promptly with a doctor, preferably an ear specialist such as an
ENT, before dispensing a hearing aid if you determine through
inquiry, actual observation, or review of any other available
information concerning the prospective user, that the prospective
user has any of the following conditions:
• Visible deformity of the ear, either congenital or traumatic
• Fluid, pus, or blood coming out of the ear within
the previous 6 months
• Pain or discomfort in the ear
• History of excessive ear wax or suspicion that
something is in the ear canal
• Dizziness, either recent or long-standing
• Sudden, quickly worsening, or fluctuating hearing
loss within the previous 6 months
• Hearing loss or ringing (tinnitus) only in one ear or a
noticeable difference in hearing between ears
• Audiometric air-bone gap equal to or greater than
15 dB at 500 Hz, 1000 Hz, and 2000 Hz
WARNING to Hearing Aid Dispenser, Outputs
over 132 dB SPL:
You should exercise special care in selecting and fitting a hearing
aid with a maximum output that exceeds 132 dB SPL because it
may impair the remaining hearing of the hearing aid user.
CAUTION: This is not hearing protection.
You should remove this device if you experience overly loud
sounds, whether short or long-lasting. If you’re in a loud place,
you should use the right kind of hearing protection instead of
wearing this device. In general, if you would use ear plugs in a
loud place, you should remove this device and use ear plugs.
CAUTION: The sound output should not be
uncomfortable or painful.
You should turn down the volume or remove the device if the
sound output is uncomfortably loud or painful. If you consistently
need to turn the volume down, you may need to further adjust
your device.
CAUTION: You might need medical help if a piece
gets stuck in your ear.
If any part of your hearing aid, like the eartip, gets stuck in your
ear, and you can’t easily remove it with your fingers, get medical
help as soon as you can. You should not try to use tweezers or
cotton swabs because they can push the part farther into your ear,
injuring your eardrum or ear canal, possibly seriously.
NOTE: What you might expect when you start using a
hearing aid.
A hearing aid can benefit many people with hearing loss. However,
you should know it will not restore normal hearing, and you may
still have some difficulty hearing over noise. Further, a hearing
aid will not prevent or improve a medical condition that causes
hearing loss.
People who start using hearing aids sometimes need a few weeks
to get used to them. Similarly, many people find that training or
counseling can help them get more out of their devices.

4 | Warnings, Cautions, & Notices Warnings, Cautions, & Notices | 5
If you have hearing loss in both ears, you might get more out of
using hearing aids in both, especially in situations that make you
tired from listening—for example, noisy environments.
NOTE: Tell FDA about injuries, malfunctions, or other
adverse events.
To report a problem involving your hearing aid, you should submit
information to FDA as soon as possible after the problem. FDA
calls them “adverse events,” and they might include: skin irritation
in your ear, injury from the device (like cuts or scratches, or burns
from an overheated battery), pieces of the device getting stuck in
your ear, suddenly worsening hearing loss from using the devices,
etc.
Instructions for reporting are available at https://www.fda.gov/
Safety/MedWatch, or call 1-800-FDA-1088. You can also download
a form to email to FDA.
NOTE: Hearing loss in people younger than 18.
• People younger than 18 should see a doctor first, preferably
an ear-nose-throat doctor, because they may have different
needs than adults.
• The doctor will identify and treat medical conditions as
appropriate.
• The doctor may refer the person to an audiologist for a
separate test, a hearing aid evaluation.
• The hearing aid evaluation will help the audiologist
select and fit the appropriate hearing aid.
A person who is younger than 18 years old with hearing loss
should have a medical evaluation by a doctor, preferably an ENT,
before buying a hearing aid. The purpose of a medical evaluation
is to identify and treat medical conditions that may affect hearing
but that a hearing aid won’t treat on its own.
Following the medical evaluation and if appropriate, the doctor
will provide a written statement that the hearing loss has been
medically evaluated and the person is a candidate for a hearing
aid. The doctor may refer the person to an audiologist for a
hearing aid evaluation, which is different from the medical
evaluation and is intended to identify the appropriate hearing aid.
The audiologist will conduct a hearing aid evaluation to assess
the person’s ability to hear with and without a hearing aid. This
will enable the audiologist to select and fit a hearing aid for
the person’s individual needs. An audiologist can also provide
evaluation and rehabilitation since, for people younger than
18, hearing loss may cause problems in language development
and educational and social growth. An audiologist is qualified
by training and experience to assist in the evaluation and
rehabilitation of hearing loss in people younger than 18.
IMPORTANT NOTICE FOR PROSPECTIVE Rx HEARING AID
USERS:
It is good health practice for a person with a hearing loss to
have a medical evaluation by a licensed physician (preferably a
physician who specializes in diseases of the ear) before purchasing
a prescription hearing aid. Licensed physicians who specialize
in diseases of the ear are often referred to as otolaryngologists,
otologists or otorhinolaryngologists. The purpose of the medical
evaluation is to assure that all medically treatable conditions that
may affect hearing are identified and treated before the hearing
aid is purchased.
Following the medical evaluation, the physician will give you a
written statement that states that your hearing loss has been
medically evaluated and that you may be considered a candidate
for a hearing aid. The physician will refer you to an audiologist or
hearing aid dispenser, as appropriate, for a hearing aid evaluation.
The audiologist or hearing aid dispenser will conduct a hearing aid
evaluation to assess your ability to hear with and without a hearing
aid. The hearing aid evaluation will enable the audiologist or
dispenser to select and fit a hearing aid to your individual needs.
If you have reservations about your ability to adapt to
amplification, you should inquire about the availability of a trial-
rental or purchase option program. Many hearing aid dispensers
now offer programs that permit you to wear a hearing aid for a
period of time for a nominal fee after which you may decide if you
want to purchase the hearing aid.
In some geographies, you must have a medical evaluation before
purchasing a prescription hearing aid. Some states allow an adult
to waive the medical evaluation.

6 | Warnings, Cautions, & Notices
A hearing aid will not restore normal hearing and will not
prevent or improve a hearing impairment resulting from organic
conditions. Use of a hearing aid is only part of hearing habilitation
and may need to be supplemented by auditory training and
instruction in lip reading. In most cases infrequent use of a hearing
aid does not permit a user to attain full benefit from it.
Some hearing instrument users have reported a buzzing sound in
their hearing instrument when they are using mobile phones,
indicating that the mobile phone and hearing instrument may not
be compatible. It is well-known that mobile phones are potential
sources of noise for hearing aids. Your Starkey Hearing Aids
have been tested for compliance to two standards that define
hearing aid immunity to digital wireless devices and meet the
requirements of ANSI C63.19- 2019 as well as the criteria for user
compatibility as defined by IEC 60118-13:2019.

Congratulations!
The hunt is over for the world’s
first custom, Bluetooth®
compatible, rechargeable hearing
aid and protection device,
powered by Starkey technology.
