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.

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 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 further 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.
MDHearing has a team of U.S.-based licensed audiologists and hearing specialists ready to
assist by phone, email, text, and video sessions.
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 di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/MedWatch, or call
1-800-FDA-1088. You can also download a form to mail to FDA.

If you have a pair of hearing aids, rst identify the left and right aid. Hearing
aids are t, and may be tuned, dierently for each ear. Therefore, they should not
be swapped.
Step 1: Charge the hearing aids.
Step 2: Place the hearing aids on your ears.
Step 3: Adjust the settings.
Quick Start Guide
Please note: The VOLT MAX may be used with the optional MDHearing
app to personalize your hearing aids. Visit https://start.MDHearing.com
for the app manual and personalization instructions.

To identify the left and right hearing aid, hold them upright in each hand with
the controls facing you. The tubing/tips point toward each other when in the
correct hand.
You may also look for the label near the end of the tubing. The blue label
indicates left ear. The red label indicates right ear.

The charging case can fully charge the hearing aids up to 3 times without being
plugged in. It takes about 90 minutes to fully charge the hearing aids and about
2 hours to fully charge the case.
On average, a full charge of the hearing aids lasts 15 hours.
Once the hearing aid is fully charged, a sensor stops the charging process. There
is no risk of battery degeneration if left on the charger. The charger can also
remain plugged in while not in use.
Charging Case Information
When the hearing aid battery is low, two beeps will repeat every 30 seconds until
it fully depletes. When the case has less than 20% power, LED2 will ash red.
Low Battery Warnings
Please note: We recommend wiping the hearing aid with a dry soft cloth to
remove any moisture or oils before placing in the charger.
