Caution and notices for users
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 in-
stead 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: This is not hearing protection.
You should turn down the volume or remove the device if the sound output is un-
comfortably loud or painful. If you consistently need to turn the volume down, you may
need to further adjust your device.
Caution: The sound output should not be uncomfortable or painful.
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.
Caution: You might need medical help if a piece gets stuck in your ear.
Remove the device from the charging case to power on automatically. You will hear a
voice prompt saying "Power On" or the remaining battery level "Battery Low" , and
then the device will automatically enter hearing aid mode. To turn off, press and hold
the touchable MFB button area for more than � seconds (When used binaurally, only
the hearing aid on the side where the touchable button is pressed will turn off), or
simply place the device back into the charging case—it will turn off automatically,
with light flashing for � second. And you will hear a voice prompt saying "Power Off".

User Manual
These WARNINGS point out situations which could cause serious injuries to the user
or to the hearing aid.
●
In some acoustic environments, over amplification can cause discomfort and
damage to the patient’s hearing.
●
Do not use your hearing aids in explosive or oxygen-enriched areas.
●
Allergic reactions to hearing aids are unlikely. However, if you experience itching,
redness, soreness, inflammation, or a burning sensation in or around your ears,
inform a hearing healthcare provider and contact your physician.
●
You may notice accelerated accumulation of earwax when using your hearing aid. This
is normal, but see your hearing healthcare provider if you continue to have difficulty.
●
In the unlikely case that any parts remain in the ear canal after the removal of the
hearing aid, contact a physician immediately. Report the event to your hearing
healthcare provider as soon as possible.
●
Remove your hearing aids for CT and MRI scans or for other electromagnetic procedures.
●
Never leave your hearing aids and/or charging case where small children and pets
can reach them.
●
If you feel pain in or behind your ear, if it is inflamed, if skin irritation or accumula-
tions of ear wax occur, please check with a hearing healthcare provider, preferably an
ear-nose-throat doctor (ENT).
●

●
Sleeping with your hearing aids in your ears is not recommended. Risks vary from
damaging your hearing aids to experiencing discomfort and/or feedback. You will
find, however, that there are many assistive devices available to you, such as wake-up
alarms that can be placed under your pillow or wristbands that vibrate when you have
a phone call.
●
Contact service.us@zdeer.com for support if you experience unexpected operations.
To report a problem involving your hearing aid, you should submit information to FDA
Note: Tell FDA about injuries, malfunctions, or other adverse events.
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: If you remain concerned, consult with a professional.
A hearing aid can benefit many people with hearing loss. However, you should know it will not re-
store normal hearing, and you may still have some difficulty hearing over noise. Further, a hear-
ing 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.
Note: What you might expect when you start using a hearing aid.
