The HD75R Series

Ready to hear better with your new HD75R 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. We suggest trying to use your new device regularly over the course of about two weeks as you will need to adapt to the brighter and clearer sounds the HD75R will provide.

HD75 app
Although your HD75R comes ready to use out of the box, you have the option of downloading the free HD75 app onto your smartphone for optimal customization (see page 14).
Please read all instructions before wearing devices.

Package Includes

Buttons & Features

Your HD75R provides comfort and control for a superior listening experience.

Bought a pair

If you bought a single HD75R you can wear it on either ear. If you bought a pair, look at the serial number on the case. One of your HD75Rs will have a bar under the serial number (the other HD75R will not have it) to differentiate between the two.

Charging your HD75R

Your HD75R comes pre-programmed and ready to use right out of the box. We recommend you charge your device before use. This could take up to 4 hours. While charging, the lights on the device will be red. You’ll know it’s fully charged when the lights turn off. If light blinks, this indicates problems charging. Disconnect and connect again. You cannot harm your device by leaving it on the charger once charged.

Recharge by inserting device so that the contacts on your HD75R align with those of the charging station. Device will be on and ready to use when removed from charging station.

Ear & Ear Tip Selection

Which Ear to Fit?
If you only have one HD75R, select which ear to fit:

If you need mild amplification select the worse ear or go with your preference.
If high amplification is needed for both sides then select the better ear.

Which Ear Tip to Select?
Your HD75R comes packaged with the medium ear tip placed on the device. You can replace the medium ear tip with a smaller or larger one.
Selecting proper ear tip size:

Make sure the ear tip has a snug fit that is secure and comfortable
If you experience feedback/whistling then try a larger ear tip for a better seal
If your own voice is echoing or is boomy try a smaller ear tip

Note: Selecting the proper size ear tip is a trade off between comfort and feedback/whistling.

Proper Placement/Insertion

Wearing the HD75R
When placing the HD75R 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). *Once inserted, turn on device by pressing both buttons on the device simultaneously for 5 seconds.

Removing the HD75R

How to remove the HD75R
- To remove the HD75R, 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 turn off your device by pushing both volume buttons for 5 seconds.

Button Function

The HD75R has two buttons that control different functions (Power, Volume, Presets, and Environment Modes). When you make a change, you will hear a voice prompt that lets you know what change you made.

Power On/Off – To power the device on or off, simply press both buttons at the same time for 5 seconds.
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.
Presets – The HD75R comes with 3 Presets. Toggle through the Presets by pressing and holding the Volume Down button for at least 2 seconds. Once you find the Preset that you are comfortable with, you can change the volume, if needed, as an adjustment. See page 13 for further details.
Environment Modes – The HD75R comes with 3 Environment Modes (every day, Restaurant, & Entertainment). You can toggle through the Environment Modes by pressing and holding the Volume Up button for at least 2 seconds. See page 16 for further details.

Customizing the HD75

You can customize your HD75R in one of two ways: selecting a preset (see p. 13) or downloading the HD75 app to your Smartphone and adjusting via the app (see p. 14).

Presets
You do not need a smartphone to customize your HD75R. Choosing the appropriate preset is often enough to provide a good listening experience. 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. Remember, to toggle through Presets, press and hold the Volume Down button for at least 2 seconds.

Preset 1 – Provides mild amplification in the high frequencies for more clarity.
Preset 2 – Provides some mid frequency and even more high frequency amplification than Preset 1. Use Preset 2 if Preset 1 still does not provide enough clarity.
Preset 3 – Provides some low and even more mid frequency amplification than Preset 2. Use Preset 3 if you need clarity as well as volume.

HD75 app

If you choose to further customize, download the HD75 app onto your smartphone. For iPhone, visit the App Store. For Android, visit Google Play. The app should recognize your HD75R without having to pair/connect to your phone’s Bluetooth, as long as your phone’s Bluetooth is on when powering on your HD75R. Select your HD75R on the initial screen, then follow instructions. Please read the User Guide within the app for more instructions.
Note: Once you customize the HD75R, the only way to access the Presets is through the HD75 app.

Equalizer (App only)

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. If sounds are tinny or you get a slight whistle, decrease Treble in small increments
Mid – Adjust the Mid frequencies to get rid of electronic-sounding voices.
Bass – This provides low-frequency amplification (150-1000 Hz). Lower the Bass if sounds are too loud or boomy. Also, if your voice is too loud or echoing then lower the Bass. If you need a bit more loudness from the device, raise the Bass in small increments.

Environment Modes

Environment Modes allow you to customize based on your listening needs in a specific environment. Toggle through modes 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. Use this throughout the day for normal use in environments that are quiet, or somewhat quiet.
Restaurant – If you are in an environment with background noise, selecting Restaurant does two things: first, it activates a 2nd microphone for directionality, and second, it automatically decreases some low and mid frequency amplification. The two steps allow for better hearing in noisy situations, focusing on capturing the clarity of speech.
Entertainment – When you want to listen to music or the television, select Entertainment. This will boost the low and mid frequencies a bit, while maintaining high frequency amplification.

Advanced Audio Features

Answering Phone Calls
Phone calls can connect to your hearing aid through any ASHA* Android- compatible device. You will continue to control volume and other phone functions, like ending a call, from your phone. Note that the microphone for your phone is still used, so you must keep the phone close to your mouth if you are using the HD75R.

For a list of ASHA-compatible devices, please see https://www.soundworldsolutions.com/product/hd75r/

Audio Streaming
Audio streaming only works on ASHA Android compatible devices. Please refer to the Audio Streaming Insert that came in your product 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.

Cleaning the HD75R
NOTE: Never use water, solvents, cleaning fluids or oil to clean your instrument. A cleaning tool is included with your HD75R. It is recommended that you use the wire loop at the end of this tool to remove any wax buildup from the ear tip and nozzle at least once per week. Use a cleaning brush or soft cloth to clean debris from around the buttons, microphone and charging contacts; inspect the receiver and ear tip regularly.

Cleaning the Ear Tips
For best comfort, and long term care, occasional cleaning of the ear tip is recommended using an alcohol pad or slightly damp cloth.

Troubleshooting

Feedback (whistling noise) is heard

Try a different preset
The gain is set too high. Decrease volume. If using the Customizer app, decrease high/mid frequencies

Ensure ear is clear of wax

No sound coming from HD75R

Make sure your battery is charged.
Remove any wax that may be blocking the ear tip or nozzle

Sound is muffled or garbled, or no sound

Check that the ear tip is mounted to nozzle correctly
Remove any wax that may be blocking the ear tip
Try a different Preset or Environment setting

Echo of your own voice/sounds too loud

Change ear tip size to one size smaller
Insert ear tip further into ear canal
Decrease Bass in small increments

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 otorhinolaryngologists. The purpose of the medical evaluation is to assure that all medically treatable conditions which may affect hearing are identified and treated before the hearing aid is purchased. A hearing aid will not restore normal hearing and will not prevent or improve a hearing impairment resulting from organic conditions. Use of a hearing aid is only part of hearing habilitation and may need to be supplemented by auditory training and instruction in lip reading. In most cases, infrequent use of a hearing aid does not permit a user to attain full benefit from it.

Children With Hearing Loss
In addition to seeing a physician for a medical evaluation, a child with a hearing loss should be directed to an audiologist for evaluation and rehabilitation since hearing loss may cause problems in language development and the educational and social growth of a child. An audiologist is qualified by training and experience to assist in the evaluation and rehabilitation of a child with a hearing loss.
