The MDHearingAid® Story The MDHearingAid AIR was developed by a board-certified Ear, Nose, and Throat physician in Chicago, IL, Dr. Cherukuri. He encountered patients in his daily practice who would benefit 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.
Dr. Cherukuri worked with world-class Doctors of Audiology and Audiologists to create the MDHearingAid AIR .

Volume Dial • To turn the Hearing Aid OFF, turn the Volume Dial downward past 0 until you feel a click. IMPORTANT: When the Hearing Aid is turned ON, it will take a few seconds to begin amplifying sound. Please raise the volume SLOWLY to avoid a sudden blast of sound.
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 find 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.
Program Best For Description Indicator 1. Normal Quiet Mode Home, watching TV, time with family. Increases sound in 1 Beep ALL frequencies. 2. Low Social Mode Social settings: group meetings, church, time with friends. Low frequencies (most background noises) up to 1000 Hz are not significantly amplified. 2 Beeps 3. High Noisy Mode Intense noise situations: parties, restaurants, traffic or large crowds. Ideal for people with high frequency hearing loss.
Using the Telephone / Telecoil Program 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.
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 find 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.
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, including those costing thousands of dollars, will restore the normal hearing of youth. However, you can maximize your return on your investment by understanding the 3 Keys to Hearing Aid Happiness: Balance: Both ears need to hear. e t Fi Happiness nc la Ba Fit: If the hearing aid does not fit 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.
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 significantly better understanding of speech and conversation, since the brain is receiving sound from both ears. • You will find there will be less overall background noise amplification.
Key #3 — Fit Hearing aids, no matter how expensive, will not work unless they are fitted correctly. Without a proper fit, it is impossible to reap the full benefit of your investment. • Your Hearing Aids comes with six different silicone Ear Domes. Choose the appropriate size Ear Dome so that the fit inside the ear canal is snug. If the fit is loose, feedback will occur, and you may hear a whistling noise when the Hearing Aids are ON.
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.
1) Battery Replacement Procedure: Click off Battery Type: The MDHearingAid AIR uses size 13 zinc-air batteries (orange tab). 2) 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. Screws 3) 4) 1minute 3. Remove orange tab from new battery. 4. Wait AT LEAST one (1) full minute for complete battery activation.
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.
Care and Cleaning 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 benefit of your MDHearingAid AIR . Earwax can clog up AIR Tubing. For best results, it may be beneficial 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.
Troubleshooting 1. Instrument makes a whistling sound. • Whistling (feedback) occurs when amplified sound returns to the microphone and is re-amplified. 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.
• 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 reflected from the ear canal. In these cases, the fit may be fine 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.
2. The sound is distorted or intermittent. • 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 dehumidifier overnight. • Lower the volume. • Turn Hearing Aid OFF completely. Open then close Battery Compartment, wait 45 seconds, and turn Hearing Aid back ON. 28 • Replace battery with a fresh one following the Procedure on page 23. •C heck the battery contacts for corrosion.
3. Instrument has a weak or no sound. • 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.

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.
Stop Using MDHearingAid AIR and Consult a Physician if: •H earing in one or both ears worsens. • Your ear becomes occluded with excessive ear wax. •H earing does not improve while using the MDHearingAid AIR • You develop an infection of your ear or ear canal. • Skin irritation develops in or around your ear canal.
Important Notice for Prospective Users Good health practice requires that a person with a hearing loss have a medical evaluation by a licensed physician (preferably a physician who specializes in diseases of the ear) before purchasing a hearing aid. Licensed physicians who specialize in diseases of the ear are often referred to as otolaryngologists, otologist or otorhinolaryngologists.
If you have reservations about your ability to adapt to amplification, you should inquire about the availability of a trial/rental or purchase/option program. Many hearing aid dispensers now offer programs that permit you to wear a hearing aid for a period of time for a fee after which you may decide if you want to purchase the hearing aid. Federal law restricts the sale of hearing aids to those individuals who have obtained a medical evaluation from a licensed physician.
