FDA warnings and cautions (USonly)
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 (an ENT). Before using this, a doctor should
determine that the use of a hearing aid is appropriate.
WARNINGS to Hearing Aid Dispensers
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
FDA warnings and cautions (USonly) 3

•Hearing loss or ringing (tinnitus) only in one ear or 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.
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.
Sound pressure level in the ears of children:
The developed sound pressure level in the ears of children can be substantially higher than in average
adults.It is recommended to perform an RECD measurement in order to ensure the correct target for the
fitted OSPL90.
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.
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.
4FDA warnings and cautions (USonly)

You might need medical help if a piece gets stuck in your ear
If any part of your hearing aid, like the eartip (dome), 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 further into your ear, injuring your eardrum or ear canal, possibly
seriously.
NOTE:
What you might expect when you start using your 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.
•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.
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 device, 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 mail to FDA.
FDA warnings and cautions (USonly) 5

Hearing loss in people younger than 18
•People younger than 18 should see a doctor first, preferably an ear-nose-throat doctor (an ENT),
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.
