Dr. Cherukuri worked with world-class Doctors of Audiology and Audiologists
to create the MDHearingAid®AIR. Built to exacting specications, the
MDHearingAid®AIR includes advanced technologies found on hearing aids
costing thousands of dollars more such as:
• Advanced feedback cancellation to reduce and eliminate "whistling"
• Advanced compression technology to magnify soft sounds and dampen
loud sounds
• Advanced noise reduction that reduces noises embedded in speech and
maximizes sound quality
• Digital amplication to accurately reproduce speech and sounds to enhance
listening comfort
• A Telecoil setting for easy use with compatible telephones or looped
environments found in many churches, theatres and public buildings
The MDHearingAid®AIR has been rigorously tested by leaders in the hearing
loss eld (ENT Physicians and Audiologists) who have unanimously agreed
that the sound quality and output is incredibly accurate.
The MDHearingAid

Story
The MDHearingAid®AIR was developed by a board-certied Ear,
Nose, and Throat physician in Chicago, IL, Dr. Cherukuri. He
encountered patients in his daily practice who would benet from
hearing aids, but many simply couldn’t afford the thousands of
dollars needed to pay for them. As a physician, he knew the
effects of untreated hearing loss: depression, social isolation,
anxiety, and other symptoms consistent with Alzheimer's disease.
Dr. Cherukuri set out to nd a reasonable solution that could
help with the most common types of hearing loss at a
reasonable price. He was looking for a “one-size-ts-most”
hearing aid, similar to reading glasses, that can easily be
purchased at the drug store.
He evaluated numerous hearing aids and sound ampliers,
including those seen on television. He found almost all of
these devices only amplied low frequencies (below 1000 Hz);
however, the majority of hearing loss is in the higher
frequencies (1000-4000 Hz), those most related to
the human voice.

Selecting a Sound Processing Program
The MDHearingAid®AIR has four Sound Processing Programs to address the
most common hearing loss environments. Try the different programs in each
environment to nd which Program works best for you.
• Once turned ON, the MDHearingAid®AIR starts on Program 1.
This is the default setting; every time the Hearing Aid is turned
OFF and then ON again, it will re-set to Program 1.
• To access the other Programs, press the Program Button and you will hear
a number of audible tones corresponding to the Program number:
1 Tone = Program 1
2 Tones = Program 2
3 Tones = Program 3
4 Tones = Telephone/Telecoil
Please note: The tones may be faint
depending on the volume setting and
background noise.

The MDHearingAid®AIR is equipped with a Telecoil Program. Telecoils, also
known as Audio Induction Loops, enable the direct magnetic coupling of your
Hearing Aid to compatible telephones and other audio sources.
Telecoils provide clear sound that is free of background noise and feedback.
Telecoils enable you to comfortably use the telephone without removing
your Hearing Aid.
To activate the Telephone/Telecoil mode (Program 4)
Push the Program Button until you hear four tones. In Telecoil mode,
the Hearing Aid microphone is disabled; only the sounds picked up
from the Telecoil are amplied through the Hearing Aid.
General Telephone Use
When using the Telecoil, be sure to center the telephone receiver over
the Hearing Aid, NOT your ear canal. Move the receiver along the
Hearing Aid to locate the clearest, strongest signal. You may have to
increase the volume of the Hearing Aid slightly. To return to normal
listening, push the Program Button until the desired program is reached.
Using the Telephone / Telecoil Program
Telephone Compatibility
Most, but not all, landline phones are Telecoil compatible. Wireless and
cellular phones rated T3 or T4 are Telecoil compatible (T4 is preferred).
Check your telephone's instruction manual to nd out its rating. Phones
rated M3 or M4 are not Telecoil compatible but are hearing aid compatible.
M3 and M4 phones will work with Programs 1-3. The speaker function on
your phone also works well with your MDHearingAid®Hearing Aids.
Compatible Loop Systems
The Telecoil Program can also help you listen in public
places equipped with Telecoil compatible assisted
listening systems. When the sign to the right is
present, it signies a Telecoil system is available.
If your Hearing Aids do not operate when the
Telecoil is ON, the loop system may not be operating
or you may be in a "dead" spot. Try positioning yourself
in a different part of the looped area, or return your
Hearing Aids to your preferred Program 1-3 and sit
as close to the speaker as possible. HEARING LOOP INSTALLED

Happiness
Getting the Most from Your Hearing Aids
Your satisfaction with hearing aids depends on the type and degree of your
hearing loss and your expectations. No hearing aids will restore the normal
hearing of youth, including those costing thousands of dollars.
However, you can maximize your return on your investment by
understanding the 3 Keys to Hearing Aid Happiness:
Patience: Using hearing aids takes practice and patience.
Balance: Both ears
need to hear.
Fit: If the hearing aid
does not t properly,
it will not work.
Key #1 — Patience
New hearing aids can be a big adjustment. Your brain has to re-learn how to
hear and listen. After many years of not hearing well, it takes time and practice
to redevelop these skills. Medical studies show that your brain requires
approximately 21 days to adjust to your new Hearing Aids. During this time:
• You may initially notice lots of background sounds. These sounds have
always been a part of your environment. In time your brain will recall how
to process these sounds by prioritizing foreground over background sounds.
• You may nd that a quiet environment is more comfortable in the
beginning of the adjustment period.
• Your voice may sound too loud. This effect is very common for new
hearing aid users, but most people get used to it over time.
• You voice may also sound 'plugged up' or like you’re talking in a barrel.
This occlusion effect is normal. The sensation usually goes away in the
rst few weeks.
• In noisy environments, you may nd it easier to understand speech by
facing the speaker. Reading lips and observing facial expressions and
body language reinforce the sound communication.

20 21
Key #2 — Balance
We are born with two ears for balance. It is best to maintain balance while
treating hearing loss. If you have hearing loss in both ears, medical studies
have shown that You will get far greater satisfaction and the BEST
results by wearing two Hearing Aids, for the following reasons:
• You will have a signicantly better understanding of speech and
conversation, since the brain is receiving sound from both ears.
• You will nd there will be less overall background noise amplication.
• You will have better hearing and understanding in noisy situations.
• You will have better localization of the direction of sounds.
• Your listening will be more pleasing, effortless, and less frustrating.
If you have hearing loss in both ears and only ordered one Hearing Aid, we
strongly encourage you to use the enclosed Offer Code for a discount on a
second MDHearingAid®AIR. As always, you will receive a 45-Day risk-free
trial with our money-back guarantee.
Key #3 — Fit
Hearing aids, no matter how expensive, will not work unless they
are tted correctly. Without a proper t, it is impossible to reap
the full benet of your investment.
•Your Hearing Aids comes with six different silicone Ear Domes. Choose
the appropriate size Ear Dome so that the t inside the ear canal is snug.
If the t is loose, feedback will occur, and you may hear a whistling noise
when the Hearing Aids are ON.
•You may nd that you require a different Ear Dome size or type once
your ear has adjusted to wearing Hearing Aids regularly.
•If you require a higher volume, consider replacing the AIR Tubing with the
Traditional Tubing System. The Traditional Tubing has a larger diameter for
maximum volume potential. (See Package Contents on page 5.)
Using Hearing Aids takes practice and patience. Some
people adjust very quickly and most adapt within a few
weeks. Please do not give up prematurely. A whole new
world of sound awaits you.

Battery Information
Low Battery Warnings:
When the battery voltage nears the end of its life, the MDHearingAid®AIR
will provide Low Battery Warning signals.
The Initial Warning will be three sets of double beeps. It is recommended
that the battery be replaced as soon as possible.
When the battery is too weak for further operation, the Final Warning will be
six sets of double beeps (resembling a motor boat sound). The hearing aid
will then shut down all audio output until a fresh battery is installed. Follow
the Battery Replacement Procedure on the next page.
Please note: Due to variations among battery manufacturers certain
batteries, when new, will give a false Low Battery Warning. For best
results, use Battery Replacement Procedure on the next page.
Battery Replacement Procedure:
Battery Type: The MDHearingAid®AIR uses size 13
zinc-air batteries (orange tab).
1. Turn the Hearing Aid OFF: rotate the Volume Dial
downward past 0 until you feel a click.
2. Remove old battery: open Battery Compartment
with screws facing up. Turn Hearing Aid over or
use magnet on cleaning tool to remove battery.
3. Remove orange tab from new battery.
4. Wait AT LEAST one (1) full minute for complete
battery activation.
5. Insert battery and close Battery Compartment.
6. Wait 45 seconds BEFORE turning hearing aid

Care and Cleaning
Battery Tips:
• Extend battery life by turning the Hearing Aid OFF when not
in use and by leaving the Battery Compartment open every night.
• New zinc-air batteries require "time to breathe." After removing
orange tab, give new battery one (1) minute to fully power up
BEFORE inserting into Battery Compartment.
• Use Magnet on Cleaning Tool to assist with the placement
and removal of the battery.
• Do not use batteries that are expired, unsealed, or showing
signs of corrosion.
• Do not leave exhausted batteries in the Hearing Aid. They may leak and
damage the Hearing Aid.
Follow these tips to keep your MDHearingAid®AIR performing optimally:
• Wipe your Hearing Aid daily with a tissue or soft cloth. Water, alcohol, or
other liquid agents will damage it.
• Keep your ears clean to maximize the benet of your MDHearingAid®AIR.
Earwax can clog up AIR Tubing. For best results, it may be benecial to clean
your ears with an over-the-counter ear wash kit or visit your physician.
• Use the wire on the Cleaning Tool to keep AIR Tubing free from debris.
• Use the brush on the Cleaning Tool to gently clean away wax and other debris.
• Do not let the Hearing Aid get wet. Do not use hair spray or a hair dryer while
wearing the Hearing Aid. Do not expose the Aid to excess moisture or heat.
• Avoid physical shock to the Hearing Aid, such as dropping it on the oor.
• Store your Hearing Aid in a cool dry place when not in use with the Battery
Compartment open.
• If you are not going to use the Hearing Aid for a prolonged period of time,
remove the battery to prevent corrosion.
Caution! Be sure to keep batteries out of reach from children and pets.
If a battery is accidentally swallowed, seek medical attention immediately,
or call The National Battery Hotline collect at 202-625-3333.

26 27
• Whistling (feedback) occurs when
amplied sound returns to the
microphone and is re-amplied.
Most hearing aids (even ones
costing thousands of dollars)
will whistle when not inserted
properly in the ear canal.
• Lower the volume if it is set too
high, and try using a non-vented
Closed Ear Dome.
• Clean any wax from the AIR
Tubing that may be interfering
with the Hearing Aid.
• If feedback is still an issue try
using the Traditional Tubing
System.
• Conrm that the Hearing Aid
is working properly by removing
the aid and covering the end of
the AIR Tubing or attached
Ear Dome with your nger.
The whistling should stop.
• Try reinserting the Ear Dome
into ear so it ts better. If that
doesn't work, try a different
sized Ear Dome.
Troubleshooting
1. Instrument makes a whistling sound.
• Occasionally, whistling may
occur when you have a blockage
of wax in the ear canal from a
cold or any condition that causes
sound to be reected from the
ear canal. In these cases, the
t may be ne and the whistling
will disappear when the condition
is corrected.
• Check for cracks in the AIR
Tubing or Base. Cracks may
become another entrance
for sound to enter and cause
feedback.
For optimal performance, the Hearing Aid Ear Domes and AIR
Tubing should be replaced every 3-6 months. Replacements
can be ordered at: www.mdhearingaid.com/accessories.

28 29
• If the hearing aid were in a
humid environment or subject
to sweat, moisture may clog
the aid and distort sounds.
Consider using a hearing aid
dehumidier overnight.
• Lower the volume.
• Turn Hearing Aid OFF
completely. Open then close
Battery Compartment, wait
45 seconds, and turn
Hearing Aid back ON.
• Replace battery with a
fresh one following the
Procedure on page 23.
• Check the battery contacts
for corrosion.
• Rotate the Volume Dial
(on/off switch) back and forth,
in case dust or lint has collected
in the controls.
• Check the Ear Domes and
AIR Tubing for wax or for any
signs of wear. Replace the Ear
Domes and AIR Tubing if they
appear stiff, bent, cracked, or
frayed. Replacements can be
ordered at: www.mdhearingaid.
com/accessories.
2. The sound is distorted or intermittent.
• Make sure the Hearing Aid is ON.
The Volume Dial should be set
above the number one (1).
• Reposition the AIR Tubing and
Ear Dome in your ear canal.
• Turn Hearing Aid OFF
completely. Open then close
Battery Compartment, wait
45 seconds, and turn
Hearing Aid back ON.
• Check the battery contacts
for corrosion.
• Rotate the Volume Dial
(on/off switch) back and forth,
in case dust or lint has collected
in the controls.
• Make sure battery is inserted
correctly and Battery Compartment
is completely closed.
• Make sure battery is fresh.
If there is any doubt, replace
with new battery following the
Procedure on page 23.
3. Instrument has a weak or no sound.

Warnings to Hearing Aid Dispensers
A hearing aid dispenser should advise a prospective hearing aid user to
consult promptly with a licensed physician (preferably an ear specialist) before
dispensing a hearing aid. If the hearing aid dispenser determines 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, then consult a physician.
• Visible congenital or traumatic
deformity of the ear.
• History of active drainage
from the ear within the
previous 90 days.
• History of sudden or rapidly
progressive hearing loss within
the previous 90 days.
• Acute or chronic dizziness.
• Pain or discomfort in the ear.
• Unilateral hearing loss of sudden
or recent onset within the
previous 90 days.
• Audiometric air-bone gap equal to
or greater than 15 decibels at 500
hertz (Hz), 1000 Hz, and 2000 Hz.
• Visible evidence of signicant
cerumen accumulation or a
foreign body in the ear canal.
Stop Using MDHearingAid®AIR and Consult a Physician if:
• Hearing in one or both
ears worsens.
• Hearing does not improve while
using the MDHearingAid®AIR
• Skin irritation develops in or
around your ear canal.
• Your ear becomes occluded with
excessive ear wax.
• You develop an infection of your
ear or ear canal.
Special care should be exercised in selecting and tting a hearing aid whose
maximum sound pressure level exceeds 132 decibels because there may be
risk of impairing the remaining hearing of the hearing aid user.
A hearing aid will not restore normal hearing and will not prevent or improve
a hearing impairment resulting from organic conditions. In most cases
infrequent use of a hearing aid does not permit a user to attain full benet
from it. The use of hearing aid(s) is only part of hearing rehabilitation and may
need to be supplemented by auditory training and instruction in lip reading.
