whether short or long-lasting. If you’re in a loud place, you should use

local poison control center immediately.

or accumulations of ear wax occur, please check with your hearing
healthcare provider or physician.

background noises. Please be aware that warning signals or noises
coming from behind, e.g. cars, are partially or entirely suppressed.
Your hearing aids have been adjusted for your hearing needs; please
do not share your hearing device with other people.

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 ngers, 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.

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 benet many people with hearing loss. However,
you should know it will not restore normal hearing, and you may still
have some difculty 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 nd 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/

Hearing healthcare information
This product may help you hear better if you:
• Strain to follow conversations when others don’t,
especially in noisy places.
• Have trouble understanding the TV.
This product may not be right for you if you:
• Consistently experience feedback (whistling) of
the hearing aid when you turn up World Volume
to a level that is comfortable for you, even after
you have followed the suggestions in these
User Manual to make sure your hearing aid ts

• Feel the hearing aid is not providing enough
amplication even at the highest World Volume
setting.
A hearing healthcare professional may be able to
help you select a different hearing aid solution to
meet your needs.
This product will not restore normal hearing and
will not prevent or improve a hearing impairment
resulting from organic conditions. This product
is designed to help you make greater use of your
remaining hearing ability. You should keep in mind
that it can take time to become accustomed to
hearing new sounds.
For best results, practice using the hearing aids as
much as possible. In most cases, infrequent use of
the hearing aids doesn’t permit you to attain full
benet from them.
