Warnings
This OTC hearing aid is for users who are 18 and older. People who are
younger than 18 with hearing loss should see a doctor, preferably an ENT,
because they may need medical testing and management. Hearing loss can
affect speech and learning, so professional fitting and continuing care are
also important.
WARNING: When to see a doctor
If you have any of the problems listed below, please see a doctor, preferably
an Ear, Nose and Throat doctor (an ENT).
• Your ear has a birth defect or an unusual shape. Your ear was injured
or deformed in an accident.
• You saw blood, pus, or fluid coming out of your ear in the past
6 months.
• Your ear feels painful or uncomfortable.
• You have a lot of ear wax, or you think something could be in your ear.
Warnings
WARNING: If you are younger than 18, do not use this. You should go to
a doctor, preferably an Ear, Nose and Throat doctor (an ENT), because
your condition needs specialized care. Over-the-counter hearing aids are
only for users who are age 18 or older.

Warnings Warnings
• You get really dizzy or have a feeling of spinning or swaying
(called vertigo).
• Your hearing changed suddenly in the past 6 months.
• Your hearing changes; it gets worse then gets better again.
• You have worse hearing in one ear.
• You hear ringing or buzzing in only one ear.
WARNING: This hearing aid should not cause pain when inserting it.
Remove this device from your ear if it causes pain or discomfort when you
insert or place it. To try again, make sure to follow the instructions. If you
feel pain or discomfort again, contact the manufacturer. If your pain or
discomfort doesn’t go away, contact your hearing healthcare professional.
You can also report this to FDA as an adverse event according to the
instructions that appear later.
CAUTIONS AND NOTICES
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: If you remain concerned, consult a professional.
If you try this device and continue to struggle with or remain concerned
about your hearing, you should consult with a hearing healthcare professional.
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.

Warnings
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.
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 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.
Note: If you experience side effects, such as skin reaction or accelerated
accumulation of ear wax accumulation, contact a physician, preferably an
Ear, Nose and Throat physician.

Tips for Getting Started
• Please refer to Your Journey to Better Hearing for a guide to
wearing your hearing aids for the first 21 days.
• Before wearing your new device, we recommend removing any
wax build up in the ear canal. A professional ear cleaning may
be necessary, as excess wax may cause feedback.
• Wear the hearing aids for a few hours the first day. Try to
increase the amount of time you wear them each day. Start by
wearing them in a quiet environment, gradually working your
way to more challenging environments, such as restaurants.
• Initially, wear the hearing aids at home. You’ll notice sounds you
may not have heard in a while, like the refrigerator humming.
Over time, your brain will learn to adapt to these new sounds.
• Have one-on-one conversations in a quiet environment.
• Listen to an audio book or podcast.
• Noisy environments can be quite challenging for new hearing
 Tips for Getting StartedTips for Getting Started
aid users (and even normal hearing people). Be patient as you
explore the more challenging listening environments.
• Ask your friends and family to help you by speaking clearly and
slowly. It will also be very helpful if they face you as they speak.
• Everyone’s experience with adapting to hearing aids is different.
Be patient as you go through the process of adjusting to them.
Most likely, your hearing has decreased over a few years time.
Your brain is now receiving more auditory information than it
has in a while and will take some time to adapt.
• Feedback/chirping can be expected when the hearing aid is
inserted in the ear with the power on. Feedback can also be
expected if you place your hand next to your ear with the
hearing aid on.
• Wind noise/wind shear may be experienced when outdoors or
any time wind turbulence over the microphone is present.

Charging Tips
• For best results, turn hearing aids off prior to charging.
• Hearing aids may be left in the charging case overnight or for
an extended amount of time.
• Hearing aids powered off prior to charging will remain off
when removed from the charging case.
• If hearing aids are charged for 2.5 hours, the expected amount
of hearing aid use time is 12-16 hours.
• A fully charged charging case can provide 3 charging cycles for
a pair of BTE4s.

Select Dome
• Plug the USB end of the charging cable into the charger plug.
Plug the micro-USB end of the charging cable into the bottom
of the charging case.
• Hearing aids must be powered off to charge. Hearing aids will
not properly charge if placed in charger while powered on. If
hearing aids are off, you will not hear feedback/chirping as you
cup them in your hand. To turn aids off, press and hold the
lower button for 3 seconds.
• Firmly place the aids in the charging wells: Right aid in the right
well, left aid in the left well. When aids are properly placed in
the wells of case, the domes and thin tubes will be in the center
indentation of the case. Charging light indicators on the case
will illuminate.
Charge Your Hearing Aids

24 25
• Place the hearing aid (powered on) in your ear (reference page
) with the dome attached to the thin tube. Open and close
your jaw with a chewing motion several times to ensure hearing
aid doesn’t move out of your ear. Use the guide below to help
you select another dome if necessary
• Keep in mind:
- With a smaller vented dome, your voice is likely to sound
more natural.
- With a larger closed dome, you may feel like you’re speaking
in a barrel.
- Always start with trying smallest to largest vented domes.
Then, try smallest to largest closed domes.

Select Dome
Expected behavior of the charging case lights once the aids are
fully charged and remain in charging case:
• If case is connected to power: The hearing aid charging lights
will turn off after 2 hours of completing the full charge. The
charging case indicator light will remain on (green).
• If case is fully charged but not connected to power: All lights on
the case will turn off after 2 hours of a full hearing aid charge.
Step 2: Select Dome
• It may take some time experimenting with various domes to
find the one that best suits your ears and listening preference.
A dome can affect comfort, the way your voice sounds, and
overall amplified sound. For your convenience, vented and
closed domes are included with your Nano Hearing Aids.
VENTED DOME CLOSED DOME
Select Dome

26 27
Tip: We encourage you to try using the hearing aid without
a dome. While domes have been provided, you may find
it more comfortable and less occluding without domes.
However, if you experience feedback or chirping without
a dome, proceed with selecting a dome that best fits
your ear.
Step 3: Attach Dome
If you’re choosing a new dome, securely attach a new dome to the
tip of the thin tube as shown.

event this happens, we recommend visiting a physician or

of the thin tube.
Blue indicator for left ear.Red indicator for right ear.
Insert Dome in Ear Canal
Hold the thin tube bend with your thumb and finger as shown.
Gently insert the dome into your ear canal.
Feedback/chirping can be expected when the hearing aid is
inserted in the ear with the power on. Feedback can also be
expected if you place your hand next to your ear with the hearing
aid on.
Tip: If uncomfortable feedback/chirping is experienced
during the insertion process, hearing aid may be turned
off prior to insertion. Once hearing aid is in the ear, turn
hearing aid on.

Step 2: Position Stabilizer
Using your finger, position the stabilizer into the curvature of your
ear. The stabilizer helps keep the aid secure in your ear.
If you find the stabilizer too long, you may cut it. It won’t affect the
functionality of the thin tube. If you feel it’s not comfortable or
not fitting in the curvature of your ear, you may cut it completely.
Be careful not to cut the thin tube itself.
