The MDHearingAid® Story The MDHearingAid® was invented by a board-certified Ear, Nose, & Throat physician in Chicago, IL. He would encounter patients in his daily practice who would benefit from hearing aids, but many simply couldn’t afford the thousands of dollars often needed to pay for them. As a physician, he knew the effects of untreated hearing loss: depression, social isolation, anxiety, and symptoms consistent with Alzheimer’s dementia.
He worked with world-class Doctors of Audiology to create the MDHearingAid® AIR. Built to exact technical specifications, the MDHearingAid® AIR includes advanced technology found on hearing aids costing thousands of dollars more such as: • Advanced Feedback Cancellation to reduce and eliminate whistling. • 2-Channel/12-Band digital amplification to accurately reproduce speech and sounds to enhance listening comfort.
Package Contents Your MDHearingAid® AIR aid is supplied with: Left Ear Right and Left thin Earhooks/tubing that screw into the base of the device RED lettering is for right ear BLUE lettering is for left ear 4 Right Ear 3 open fit domes, 3 closed domes This selection of domes is designed to fit most adult ears. The 3 domes with vents allow natural sound to enter the ear and reduce the 'plugged up' feeling sometimes encountered.

Changing the Battery Before inserting a new battery into the hearing aid, remember to remove the adhesive tab. Do not use batteries on which there is a sticky residue from the tab or other unwanted substance as this can block the battery airholes. Push the nail grip downwards to swing open the battery compartment. The nail grip is located below the power switch at the bottom of the hearing aid. Tip: Use the magnet in the end of the brush to simplify battery removal and replacement.
Changing the Battery (continued) Low Battery Warning When the battery voltage nears the end of life, the MDHearingAid AIR will provide a low battery warning signal. The initial warning will be three sets of double beeps every 10 minutes. At this point the hearing aid is still functioning, but it is recommended that batteries be replaced as soon as possible.
Recommended Battery Type The MDHearingAid® AIR uses size 13 / 13A zinc-air batteries. Please note the expiration date on the battery. Also, do not leave exhausted batteries in the hearing aid, as they may leak and damage the hearing aid. The life of the battery depends on a number of factors, such as the settings of your hearing aids and the number of hours used per day. In rare cases, a new battery may be exhausted because it was not sealed properly.
Placing the Hearing Aid in Your Ear 1. Screw on the earhook (Red = Right Ear, Blue = Left Ear) to the base of the hearing aid (refer to the diagrams on pages 4 and 6) 2. C hoose the appropriate size of dome for your ear so that the fit is snug. If the fit is loose, you may hear a whistling noise when the hearing aid is on. Also, make sure that the dome does not slip off easily, or it could become dislodged in your ear canal. 3. G ently pull the outer ear backwards and upwards with the one hand.
5. When the hearing aid is in its correct position, turn it on and adjust the volume. To avoid whistling or “feedback”, make sure the eardome fits securely in the ear canal. Try the different sized domes to see which fits best. With a secure fit, there will not be whistling (you can see this by covering the eardome opening with your finger and the whistling should cease). If whistling is still heard, see the Troubleshooting section, page 24.
Turning the Hearing Aid On The MDHearingAid®AIR uses a volume dial with a built in on/off switch (like traditional radios). Turn off the hearing aid, by turning the volume dial downward below 1 until you feel a click. The hearing aid is now off. Turn the volume dial upward, past the click, and the hearing aid is now turned on. When the hearing aid is turned on it will take a few seconds to begin amplifying sound. This designed to allow the user time to put the hearing aid in their ear.
Selecting a Program The AIR has 4 programs designed to address the most common hearing loss scenarios. Try the different programs, depending on your environment to find the program that works best for you. Program Description Best For 1 Normal "Quiet Mode" Flat hearing loss. Mild, moderate, or moderately-severe flat hearing loss in ALL frequencies. Home, watching TV, time with family. 2 Low Cut "Party Mode" Sloping below 1000 Hz. Normal hearing in the low pitches.
Using the Telephone/Telecoil Capability The MDHearingAid® is equipped with a Telecoil, also known as an Audio Induction Loop. Telecoils enable the direct magnetic coupling of your hearing aid to telephones and other compatible audio sources. Telecoils provide clear sound that is free of background noises and feedback. Telecoils enable you to comfortably use the telephone without removing the aid. Use Program 4 (4 beeps) to activate the Telecoil mode.
Compatibility. Most (not all) corded phones are telecoil compatible. Wireless (Cell) Phones which are rated T3 or T4 are telecoil compatible (T4 is preferred). Check your telelphone's instruction manual to find out whether your phone has this capability. Some hearing aids users have reported a buzzing sound in their hearing aids when they are using cell phones, indicating that the cell phone and hearing aid may not be compatible. Speakerphone function also works well with your hearing aid. Loop Systems.
Getting the Most from Your Hearing Aid Your satisfaction with hearing aids depends on the type and degree of your hearing loss and your expectations. No hearing aid can restore the normal hearing of our youth, including those costing thousands of dollars.
Patience A new hearing aid can be a big adjustment. Your brain has to relearn how to hear and listen—in many cases to sounds it hasn’t processed in years. The amazing thing is that it still can—all these years later but it takes time and practice. In fact, medical studies have shown that your brain requires several weeks to adjust to your new hearing environment and become accustomed to your new hearing aids. During this time: • You may initially notice lots of background sounds.
Getting the Most from Your Hearing Aid (cont’d) • If you are a new to hearing aids, be aware that there will be sounds that you may not have heard in a long time. You will be able to tune out background noise in a short period of time. • In noisy environments, you may find it easier to understand speech by facing the speaker. Focus on reading lips and observing facial expressions and body language. • Your own voice may sound too loud.
Balance We are born with 2 ears for a reason. It is best to maintain balance in 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 2 hearing aids for the following reasons: 1. Significantly better understanding of speech and conversation, since the brain is receiving a balanced signal from both ears 2. Less overall background noise amplification 3.
Getting the Most from Your Hearing Aid (cont’d) If you have hearing loss in both ears, but only ordered 1 aid, we strongly encourage you to try one aid in each ear. Use the enclosed coupon for a discount on your second aid. As always, you will receive a 45 day risk-free trial and money-back guarantee. Fit Hearing aids, no matter how expensive, are almost useless if they don’t fit well. Without a proper fit, it is impossible to reap the full benefit of your investment.
Replacement of Tubes & Domes For OPTIMAL PERFORMANCE, the hearing aid tubing and domes should be replaced every 3-6 months: • Over time, hearing aid tubing and domes may become stiff and discolored. • Replacing tubes and domes regularly keeps your hearing aids sounding and feeling like new. • Visit www.mdhearingaid.com, where we offer a choice of different sizes of tubing if you are having difficulty achieving a proper fit.
Maintenance & Care Follow these suggestions to keep the hearing aid performing optimally: • Clean your hearing aid daily with a tissue or soft cloth. Do not use water, alcohol, or other liquid agent to clean the hearing aid as it may damage it. • Keep your ears clean to maximize the benefit of your MDHearingAid®. Earwax can clog up your hearing aid tubing and cause it to not work properly.
In Case of Malfunction Should your hearing aid not function properly, try the following: • Make sure the hearing aid is switched on. • Disconnect the tubing from the hearing aid and check for moisture in the tubing. • Check that the dome or tubing is not blocked by earwax. Use the included brush, and also try to blow air through the ear tubing. • Change the battery and make sure the new battery is inserted correctly. • Read the troubleshooting guide on the following pages. •C heck the website www.
Troubleshooting 1. Instrument makes a whistling sound • Whistling (feedback) occurs when amplified sound returns to the microphone and is re-amplfied. Most hearing aids (even ones costing thousands of dollars) will whistle when not inserted properly into the ear canal. • Confirm that the hearing aid is working properly by removing the aid and covering the hole in the tubing/domes with your finger (the whistling should stop).
• Check for any cracks in the tubing or the earhook. For optimal performance, the hearing aid domes should be changed every 3-6 months. • Lower the volume if it is set too high, and try using a non-vented dome. 2. Instrument has a weak or no sound • Make sure battery is inserted correctly and battery door is completely closed. • Make sure the volume control is on. (volume dial should be set above the number 1). • Make sure battery is fresh.
3. Sound is distorted or intermittent • Rotate on/off switch (volume dial) back and forth, in case dust or lint has collected in the controls. • Check the battery contacts to be sure they are not corroded. • If the hearing aid was in a humid environment or subject to sweat, moisture may clog the aid and distort sounds. Consider using a hearing aid dehumidifier overnight. 26 • Lower the volume. • Replace the battery with a fresh one.

Warning 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: • Visible congenital or traumatic deformity of the ear.
Stop using the MDHearingAid® and consult a physician if: • Hearing in one or both ears worsens. • Your ear becomes occluded with excessive ear wax. • Hearing does not improve while using the MDHearingAid®. • 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, otologists 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 nominal 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.
Notice of Cancellation YOU MAY CANCEL THIS TRANSACTION, WITHOUT ANY PENALTY OR OBLIGATION, WITHIN 45 DAYS FROM THE DATE OF PURCHASE.
