Turning on your device

Your device uses the battery door to turn the device on and off.

WHISTLING may be heard if the device is turned on but not securely in your ear. This is normal and a sign that your device is working. Once the tubing is properly fitted, the whistling will stop.

If the whistling continues while in your device is your ear, please contact MDHearing Support.

 

Wearing your device

WYLE
  • Place tip in entrance of ear canal.
  • Put the body of the amplifier behind your ear.
  • Move ear lock into bowl of ear.

 

Changing the Battery

MDHearing AMP uses size 13/13A zinc-air batteries.

Before inserting a new battery into your device, remember to remove the pull-tab and wait a full minute for the battery to charge.

Do not use batteries on which there is a sticky residue from the tab or other unwanted substance as this can block the battery air hole.

The battery must be placed with the plus (+) sign up. If the battery compartment does not close easily, the battery is inserted incorrectly.

Note: Never force the battery door shut. It may permanently damage your device.

The MDHearing AMP uses size 13/13A zinc-air batteries. Please note the expiration date on the battery, and never leave exhausted batteries in the device, as they may leak and damage the device.

The life of the battery depends on a number of factors, such as the settings of your device and the number of hours used per day.

In rare cases, a new battery may be exhausted because it was not sealed properly. If your device does not work after replacing a battery, try inserting a different new battery and remember to wait a full minute after removing the pull-tab on the battery before use.

Always remove the battery from your device if it will not be used for a prolonged period of time.

CAUTION: Batteries can be harmful if swallowed. 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.

NoisyLarge crowds, restaurants, traffic, nature sounds, or high octave music.Three beeps
RestaurantReduce background noise in any loud environment.Four beeps

To change the amplification program on your device, press the program button. The number of beeps the device makes indicates which program that your device is now set to.

(2 beeps –> Social Program, 3 beeps –> Noisy Program, etc).

MDHearing AMP defaults to the Quiet program when the device is turned off and on.

 

Maintenance & Care

Daily cleaning is essential to keeping your your device performing optimally.

    • Clean the tubing and tip of your device with the included cleaning wire attached to the cleaning tool.
    • The most common issue is small blockages of hardened earwax that have hardened in the tubing, blocking sound from getting to your ear. These blockages can be nearly invisible to the human eye. Running the cleaning wire through the tubing every day will make sure that your tubing lasts as long as possible.
Cleaning Tubing with the Cleaning Tool on the MDHearing AMP
  • Clean the body of your device daily with a tissue or soft cloth. and use the included brush to gently clean away wax and other debris. Do not use water, alcohol, or other liquid agent to clean the device as it may damage it.
  • Keep your ears clean. Earwax can clog up your devices tubing and cause it to not work properly. For best results, it may be beneficial to clean your ears with an over-the-counter ear wash kit or visit your physician.
  • Avoid exposing your device to excess moisture or heat. Do not use hair spray or a hair dryer while wearing your device.
  • Avoid physical shock, such as dropping it on the ground.
  • Store your device in a cool dry place when not in use
  • If you are going to store your device for a prolonged period of time, remove the battery to prevent any possible damage from corrosion

No sound from your device

  • Clean your tubing.

    Your device relies on a thin tube and the ComfortTip to provide enhanced sound to your ear, as such a small amount of debris or hardened earwax can block the sound from your device completely. A cleaning wire has been including on your cleaning tool, and we recommend cleaning the tubing on a daily basis.

    How to clean your tubing

    1. Remove tubing from the device. It may be helpful to turn the tubing at a ninety degree angle and then use your fingernail to pop the tubing off.

      NOTE: If you have a battery in the device, you should hear a whistle from the MDHearing. This is normal and a sound that indicates your device is working properly. Open the battery door fully to silence your device.

    2. Run the cleaning wire fully through the tubing and through the ComfortTip multiple times. Earwax and other blockages can be nearly invisible to the naked eye.
    3. Place the tubing back on your device and test. If the device still does not function correctly, check to see if the tubing does not have any perforations or damage. If the device whistles without tubing on but does not produce sound with tubing, you may need to purchase new tubing. We recommend the tubing and tips are replaced every three months.
  • Make sure battery is inserted correctly (positive side up) and battery door is completely closed.
  • Make sure battery is fresh. If there is any doubt, try a new one (remember to remove the pull-tab on the battery surface and wait one full minute before using a new battery).
  • Check the battery contacts for corrosion.
  • Reseat the ComfortTip in your ear canal.
  • Check the tips for wax that may be blocking or for any signs of wear. Replace the tips if they appear stiff, bent, cracked, or frayed.
  • Humid environments, sweat, and moisture may clog the device and distort sounds. Consider using a hearing instrument dehumidifier overnight.
  • If your problem persists, email us at support@mdhearing.com with a description of your problem

Excessive Whistling

The device makes a whistling sound when in the ear

  • Whistling (feedback) occurs when the amplified sound returns to the microphone and is re-amplfied.
  • You can confirm that the MDHearing is working properly by removing the device and covering the hole in the tubing tips with your finger (the whistling should stop).
  • Sometimes feedback may occur when you have a blockage of wax in the ear canal, a stiff eardrum (from a cold, for example) or any condition that causes sound to be reflected from the ear canal. In these cases, the fit may be fine, and the feedback will disappear when the condition is corrected.
  • Check for any cracks in the tubing. For optimal performance, the tubing and ear tips should be changed every 3-6 months.
  • Try a program with a lower volume setting
  • Clean any wax that may be interfering with the tubing

The device makes a whistling sound with no tubing attached

  • Whistling without tubing is a sign that your device is working properly.
  • Open the battery door to turn off your device and stop the feedback from occuring.

The device whistles intermittently

  • Check that the tubing is fully pushed onto the device and the ComfortTip is pushed fully onto the tubing. The end of ComfortTip should be flush with the end of the tubing when properly assembled sure the MDHearing
  • Make sure the ComfortTip is properly placed into the ear canal
  • Check the tips for wax that may be blocking or for any signs of wear. Replace the tips if they appear stiff, bent, cracked, or frayed.

If the problem persists, email us at support@mdhearing.com with a description of your problem.

Using the Telephone

When using your device with the telephone, try various positions with the telephone receiver, until you discover the arrangement that works best for you.

  1. Try holding the telephone near your device's microphone at the front and top of your ear.
  2. Also try holding the phone behind your ear, below your ear, or angled such that the phone receiver is tilted and open forward.
  3. Your device can also be used with the speaker phone function.

Getting the most from your device

To get the most out of your device, remember these 3 keys:

  1. ACCLIMATION

    When you start using any amplification device, your brain has to learn how to listen to sounds that it has not had to process in years or has never processed.

    This can be a big adjustment, but the human brain is an amazingly adaptable, and at any age age it can still can relearn to how to properly process these sounds, but it takes time and practice. Medical studies have shown that your brain requires several weeks to adjust to a new sound environment and become accustomed to your new amplification device. During this time:

    • You may initially notice lots of background noises. These noises have always been a part of your environment, and in time your brain will tune out many of them.
    • You may find that a quiet environment is more comfortable in the beginning.
    • Gradually introduce new listening environments as your ears become accustomed to the sounds from your device and remember to try all four programs.
    • The addition of new sounds in your life can be overwhelming. Try wearing your device for a short period each day and gradually extend the time that you wear them as you feel comfortable.
    • In noisy environments, you may find it easier to understand what is being said by facing the speaker.
    • Your own voice may sound too loud. This is very common for new users. Most people find that they get used to the level of their own voice in a few days.
    • You may also feel plugged up or feel like you’re talking in a barrel. This is called the occlusion effect is a normal reaction to having something in your ear canal. The sensation usually goes away in the first few weeks.

    Using a amplification device to its fullest can take practice and patience. Some people adjust very quickly, and most adapt within a few weeks. Please do not give up prematurely.

  2. QUALITY OF LIFE

    Everyone is born with two ears for a reason. The brain takes the sound input from both ears to understand a particular sound or voice. It is best to maintain balance by wearing a MDHearing in each ear. By maintaining balanced amplification you will experience:

    • Significantly better understanding of speech and conversation.
    • Less overall background noise amplification.
    • Better hearing and understanding in noisy situations.
    • Better localization of the direction of sounds.
    • Listening will be more pleasing and effortless.
    • Sound is balanced and more natural, especially music.
  3. THE COMFORT ZONE

    Better hearing is a journey. Many people tend to crank up the volume when they miss a word or two—resist the temptation to do this, hearing is not just about volume. The most important thing you can do is set the volume to a comfortable level and let your brain adjust. Here's a great way to find the best volume to start with:

    • Find a friend and a small, quiet room.
    • Have your friend talk to you in a normal conversational voice.
    • Adjust the volume on your hearing aid until their voice is at a comfortable level. Do not worry about if you are catching every word. Set the volume so your friends voice is not overwhelming and is not barely a whisper.
    • Now that we've created a nice baseline volume for your brain, cycle through the program settings to see which program sounds best with your hearing.
    • Resist the temptation to fiddle constantly with the volume, unless absolutely necessary. The world can be a loud place, but your brain will eventuially adjust if you give it the oppurtunity.
    • Remember to enjoy you hearing! Every sound is a blessing, and sometimes it's easy to forget how fortunate we are to hear anything and everything.
