The HD75 Series Ready to hear better with your new HD75 device? It may take some time to get used to the amplification provided by your new device. You will hear many sounds with clarity that you are not used to hearing. Ambient and environmental sounds like shuffling papers, cutlery, and dishes may be distracting at first. Your brain needs to get used to these sounds.
Congratulations on Your New HD75! Take a moment to familiarize yourself with your HD75. Package Includes: Ear Tips (5 sizes) Cleaning Tool HD75 * with medium ear tip Batteries HD75 Carry Case 4 *If you bought a pair of the HD75s see page 6.
HD75 Buttons & Features Buttons & Features: Microphones Volume Up/ Environment Modes Volume Down/ Presets Flexible Length Tube Ear Tip Receiver Battery Door Your HD75 provides comfort and control for a superior listening experience.
Bought a pair? If you bought a single HD75 you can wear it on either ear. If you bought a pair, look at the serial number on the battery door. One of your HD75s will have hashtags (####) after the serial number (the other HD75 will not have hashtags) to differentiate between the two.
Ready out of the box Your HD75 comes pre-programmed and ready to use right out of the box. You can adjust for: • Physical Fit • Presets • Volume • Environment Modes To power on, insert battery (+ side up) as shown and close the door. To power off, open the battery door.
Ear & Ear Tip Selection Which Ear to Fit? Which Ear Tip to Select? If you only have one HD75, select which ear to fit: Your HD75 comes packaged with the medium ear tip placed on the device. You can replace the medium ear tip with a smaller or larger one. • If you need mild amplification select the worse ear or go with your preference.
Proper Placement/Insertion Wearing the HD75 When placing the HD75 in your ear, be sure to place the body of the device (the section with the buttons) behind your ear – not above the ear. Insert the Receiver with the ear tip as deep as you can while maintaining comfort (see image to the right). Lower the Volume on your HD75 during placement and insertion on your ear to avoid Feedback.
Removing the HD75 How to remove the HD75 To remove the HD75, simply grab the flexible tube by the ear canal and gently pull back and out to remove it from your ear. Do not forget to open the battery door when not in use to preserve the battery life.
Button Function The HD75 has two buttons that control different functions (Volume, Presets, and Environment Modes). When you make a change, you will hear a voice prompt that lets you know what change you made. Volume – To increase volume, press and release the Volume Up button. To decrease volume, press and release the Volume Down button. When you have reached upper or lower limits of volume, you will no longer hear a voice prompt. Instead, you will hear beeps, which mean you have reached the limits.
Customizing the HD75 Customize your HD75 by either selecting one of the three Presets (see p. 13) or by downloading the HD75 app onto your Smartphone (see p. 14). Customize Presets The HD75 comes with 3 Presets. The default setting is Preset 1. The device will tell you which Preset has been selected – “Preset 1”, “Preset 2”, “Preset 3”.
Presets If you download the HD75 app and run the hearing screening program, skip this page and go to page 14 (HD75 app), if not, then continue here. A Preset is a pre-programmed frequency response to provide certain amounts of amplification at different frequencies. Your task is to select the Preset that provides you with comfortable hearing, at which point you can adjust Volume and/or Environment Modes to help you find the most clear and comfortable listening level.
HD75 app Download the HD75 app onto your Smartphone. For iPhone, visit the App Store. For Android, visit Google Play. The app should recognize your HD75 without having to Pair/Connect to your phone’s Bluetooth, as long as your phone’s Bluetooth is on when powering on your HD75. Select your HD75 on the initial screen, then follow instructions. Please read the User Guide within the app for more instructions. Note: Once you customize the HD75, the only way to access the Presets is through the HD75 app.
Equalizer The Equalizer, available only in the HD75 app, allows you to make adjustments to either a Preset or Personal Profile (your customized profile using the Hearing Screening). You can adjust overall Volume, Treble, Mid, and Bass. Equalizer Volume – Use this to adjust overall volume, all frequencies will be adjusted simultaneously. Treble – Use this to adjust the higher frequencies (>2300 Hz) for more clarity.
Environment Modes Environment Modes allow you to select a mode that fits the environment you are in. Everyday, Restaurant, and Entertainment are available to toggle through by pressing and holding the Volume Up button. Environment Modes may be selected on the device (or through the HD75 app) anytime, no matter what Preset you have chosen or if you have downloaded the HD75 app and run the Hearing Screening. Everyday – This is the default mode out of the box.
Care & Cleaning Care & Cleaning Do your best to keep your hearing instrument clean at all times. Heat, moisture and foreign substances can result in poor performance.

Important Notice For Prospective Hearing Aid 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 otorhynolaryngologists.
Important Notice For Prospective Hearing Aid Users Federal law restricts the sale of hearing aids to those individuals who have obtained a medical evaluation from a licensed physician. Federal law permits a fully informed adult to sign a waiver statement declining the medical evaluation for religious or personal beliefs that preclude consultation with a physician. The exercise of such a waiver is not in your best health interest and its use is strongly discouraged.
