1 Introduction

Congratulations on the purchase of your new hearing aids. ReSound’s innovative sound technology and design, combined with the customized programming selected by your hearing care professional, will make hearing a more enjoyable experience.

Please read this manual carefully in order to wholly beneﬁt from the use of your hearing aids. With proper care, maintenance, and usage, your hearing aids will aid you in better communication for many years.

2 Intended use

Generic air-conduction hearing aids are wearable sound-amplifying devices intended to compensate for impaired hearing. The fundamental operating principle of hearing aids is to receive, amplify, and transfer sound to the eardrum of a hearing-impaired person.

3 Becoming accustomed to ampliﬁcation

While purchasing hearing aids is a major step, it is only one step in a process toward more comfortable hearing. Successfully adapting to the ampliﬁcation of your hearing aids takes time and consistent use.

You will enjoy more beneﬁts from your ReSound hearing aids by taking the following actions:

Wear the hearing aids regularly in order to get comfortable with using them

• It takes time to get used to hearing aids. Ask your hearing care professional to design a schedule tailored just for you

• As you get more comfortable with your hearing aids, increase the wearing time and wear them in multiple types of listening situations

400738011US-17.07-Rev.B.indd 4 03-07-2017 13:51:02

It may take as long as several months for your brain to get used to all the “new” sounds around you. Following these suggestions will give your brain time to learn how to interpret ampliﬁcation and increase the beneﬁts you get from using ReSound hearing aids.

4 i Hearing aid expectations

A hearing aid will not restore normal hearing and will not prevent or improve a hearing impairment resulting from organic conditions. Consistent use of the hearing aid is recommended. In most cases, infrequent use does not permit you to attain full beneﬁt from it.

The use of a hearing aid is only part of hearing rehabilitation and may need to be supplemented by auditory training and instructions in lip-reading.

8 Telephone use

With a hearing aid you are able to use a phone in a number of ways.

8.1 Normal use

To ﬁnd the best way to use a telephone or smartphone while wearing your hearing aids may require practice. One or more of the following suggestions may be helpful:

1. Hold the telephone towards the ear (close to the hearing aid’s microphone)

2. If whistling occurs, it may take a few seconds of holding the telephone in the same position before the hearing aid eliminates the whistling

3. Whistling may also be stopped by holding the telephone slightly away from the ear

NOTE: Depending on your individual needs, your hearing care professional may activate a program speciﬁcally for telephone use.

8.2 Telecoil

Your hearing aids contain a telecoil. The Telecoil program may help to improve speech understanding with Hearing Aid Compatible (HAC) telephones and in theaters, cinemas, houses of worship etc. that have a hearing loop installed.

When you switch on the Telecoil program, your hearing aids pick up signals from the hearing loop or HAC telephone.

Your hearing care professional can activate the Telecoil program.

400738011US-17.07-Rev.B.indd 19 03-07-2017 13:51:16

NOTE: The telecoil cannot work without a hearing loop (aka induction-loop) or a HAC telephone. NOTE: If you are having trouble hearing with the hearing loop, ask you hearing care professional to

adjust the program. NOTE: If there is no sound from the hearing aids in a hearing loop system and an active Telecoil program, the hearing loop system may not be turned on or is not operating correctly. NOTE: The sound from the hearing loop and the hearing aids’ microphones can be mixed to your preference - either during the ﬁtting session or via your smartphone app or your Remote Control 2.

8.2.1 Hearing loop systems

To use hearing loop systems, follow these steps:

1. Switch your hearing aid to the Telecoil program

2. Find a good spot. Reception is not clear in all locations; it depends on the hearing loop. Look for signs or ﬁnd another spot to sit

3. If needed, adjust the volume

4. When you leave, switch to your preferred program

8.2.2 HAC telephone

Some smartphones are hearing aid compatible (HAC) - others are not. The HAC phone establishes a small hearing loop that your hearing aids connect to. Switch to the Telecoil program if you want to use a HAC phone. The telecoil picks up the HAC telephone’s signal and converts it to sound.

400738011US-17.07-Rev.B.indd 20 03-07-2017 13:51:16

To use the HAC telephone, follow these steps:

1. Switch your hearing aid to the Telecoil program

2. Pick up the telephone and place a call or answer a call

3. Hold the telephone close to the hearing aid, and tilt it slightly outwards

4. Listen to the dial tone and move the telephone to get the best reception

5. If needed, adjust the volume

6. When you hang up, switch to your preferred program

NOTE: If the phone has a poor telecoil signal, use the microphone program. To avoid whistling, do not hold the handset too tightly against your ear. NOTE: Ask your hearing care professional to enable the Telecoil program in your hearing aids. NOTE: If you see a “M3”, “M4”, “T3”, or “T4” on the box, then the smartphone is HAC compliant. NOTE: If you ﬁnd it dicult to obtain a good result while using your smartphone, your hearing care professional will be able to give you advice on available wireless accessories to enhance listening capabilities. NOTE: Ask your smartphone dealer or hearing care professional for advice regarding HAC smartphones.

400738011US-17.07-Rev.B.indd 21 03-07-2017 13:51:16

8.3 Phone Now

By placing a magnet on the telephone receiver, your hearing aids automatically switch the telephone program on when the receiver is close to your ear. When you remove the receiver from your ear, the hearing aids automatically return to the previous listening program.

NOTE: Ask your hearing care professional to enable Phone Now as one of your programs.

8.3.1 Place the Phone Now magnet

Follow these steps in order to place the Phone Now magnet properly:

Clean the telephone thoroughly. Remove foil from magnet. Place the magnet.

400738011US-17.07-Rev.B.indd 22 03-07-2017 13:51:17

WARNING: IF A MAGNET IS SWALLOWED, SEEK IMMEDIATE ADVICE FROM A MEDICAL PRAC TICIONER.

NOTE: Ask your hearing care professional to enable Phone Now as one of your programs. NOTE: Do not cover the loudspeaker opening with the magnet. NOTE: If Phone Now does not work to your satisfaction, moving the magnet to another position

may improve ease of use and comfort while speaking. NOTE: If the hearing aids do not switch to the telephone program every time, you can reposition the Phone Now magnet or add additional magnets.

NOTE: Use a recommended cleaning agent to clean the telephone.

8.3.2 How to use Phone Now

1. Lift the telephone to your ear

2. When you hear a short melody, the phone program is active

15 Tinnitus Sound Generator module

15.1 Intended use for TSG module

Your ReSound hearing aid includes the Tinnitus Sound Generator (TSG) module, a tool for generating sounds to be used in tinnitus management programs to relieve suering from tinnitus.

The TSG can generate sounds adjusted to the speciﬁc therapeutic needs and your personal preference as determined by your doctor, audiologist, or hearing care professional.

Depending on the selected hearing aid program and the environment you are in, you will sometimes hear the therapeutic sound resembling a continuous or ﬂuctuating noise.

15.2 User instructions for TSG

15.2.1 Description of device

The Tinnitus Sound Generator (TSG) Module is a software tool that generates sounds to be used in tinnitus management programs to relieve suering from tinnitus.

15.2.2 Explanation of how the device functions

The TSG module is a frequency and amplitude shaped white-noise generator. Noise signal level and frequency characteristics can be adjusted to the speciﬁc therapeutic needs as determined by your doctor, audiologist or hearing care professional.

Your doctor, audiologist or hearing care professional can modulate the generated noise with the purpose of making it more pleasant. The noise can then resemble, for example, crashing waves on a shore.

400738011US-17.07-Rev.B.indd 38 03-07-2017 13:51:31

Modulation level and speed can also be conﬁgured to your likes and needs. An additional feature can be enabled by your hearing care professional that allows you to select predeﬁned sounds that simulate sounds from nature, such as breaking waves or running water.

If you have two wireless hearing aids that support ear-to-ear synchronization this functionality can be enabled by your hearing care professional. This will cause the Tinnitus Sound Generator to synchronize the sound in both hearing aids.

If your tinnitus troubles you only in quiet environments, your doctor, audiologist or hearing care professional can set the TSG module so that it becomes audible exclusively in such surroundings. The overall sound level can be adjusted via an optional volume control. Your doctor, audiologist or hearing care professional will review with you the need for having such a control.

For hearing aids where ear to ear synchronization is enabled, your hearing care professional can also enable environmental monitoring synchronization so that the TSG noise level is automatically adjusted simultaneously in both hearing aids dependent on the background sound level. Additionally, if the hearing aid has a volume control, then the background noise level monitored by the hearing aid and the volume control can be used simultaneously to adjust the generated noise level in both hearing aids.

400738011US-17.07-Rev.B.indd 39 03-07-2017 13:51:31

15.2.3 The scientiﬁc concepts that form the basis for the device

The TSG module provides sound enrichment with the aim of surrounding the tinnitus sound with a neutral sound, which is easily ignored. Sound enrichment is an important component of most approaches to tinnitus management, such as Tinnitus Retraining Therapy (TRT).

To assist habituation to tinnitus, this needs to be audible. The ideal level of the TSG module, therefore, should be set so that it starts to blend with the tinnitus, and so that you can hear both your tinnitus as well as the sound used.

In a majority of instances, the TSG module can also be set to mask the tinnitus sound, so to provide temporary relief by introducing a more pleasant and controllable sound source.

15.2.4 TSG volume control

The sound generator is set to a speciﬁc loudness level by the hearing healthcare professional. When switching the sound generator on, the volume will have this optimal setting. Therefore, it might not be necessary to control the volume (loudness) manually.

However, the volume control provides the ability to adjust the volume, or amount of stimulus, to the liking of the user.

The volume control is an optional feature in the TSG module used for adjusting the sound generator output level. To prevent unintended usage by pediatric or physically or mentally challenged users, the volume control must, if enabled, be conﬁgured to only provide a decrease of the sound generator output level.

400738011US-17.07-Rev.B.indd 40 03-07-2017 13:51:31

15.2.5 Using TSG with smartphone apps

The tinnitus sound generator control via hearing aid push buttons can be enhanced with wireless control from a TSG control app on a smartphone or mobile device. This functionality is available in supported hearing aids when a hearing healthcare professional has enabled the TSG functionality during ﬁtting of the hearing aid.

To use smartphone apps the hearing aid must be connected with the smartphone or mobile device.

NOTE: To use smartphone apps, the hearing aid must be connected with the smartphone or mobile device.

15.3.3 Prescription use of a Tinnitus Sound Generator hearing aid

The TSG module should be used as prescribed by your doctor, audiologist or hearing healthcare professional. In order to avoid permanent hearing damages, the maximum daily usage depends on the level of the generated sound.

Should you develop any side eects from using the sound generator, such as dizziness, nausea, headaches, perceived decrease in auditory function or increase in tinnitus perception, you should discontinue use of sound generator and seek medical evaluation.

The target population is primarily the adult population over 18 years of age. This product may also be used with children 5 years of age or older. However, children and physically or mentally challenged users will require training by a doctor, audiologist, hearing healthcare professional or the guardian for the insertion and removal of the hearing instrument containing the TSG module.

400738011US-17.07-Rev.B.indd 42 03-07-2017 13:51:31

15.3.4 Important notice for prospective sound generator users

A tinnitus masker is an electronic device intended to generate noise of sucient intensity and bandwidth to mask internal noises. It is also used as an aid in hearing external noises and speech.

Good health practice requires that a person with a tinnitus condition have a medical evaluation by a licensed physician (preferably a physician who specializes in diseases of the ear) before using a sound generator. Licensed physicians who specialize in diseases of the ear are often referred to as otolaryngologists, otologists or otorhinolaryngologists.

The purpose of medical evaluation is to assure that all medically treatable conditions that may aect tinnitus are identiﬁed and treated before the sound generator instrument is used.

The sound generator instrument is a tool to generate sounds to be used with appropriate counseling and/ or in a tinnitus management program to relieve patients suering from tinnitus.

400738011US-17.07-Rev.B.indd 51 03-07-2017 13:51:31

23 i Important notice for prospective hearing aid users (US only)

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 medical evaluation is to assure that all medically treatable conditions that may aect hearing are identiﬁed and treated before the hearing aid is purchased. Following the medical evaluation, the physician will give you a written statement that states that your hearing loss has been medically evaluated and that you may be considered a candidate for a hearing aid. The physician will refer you to an audiologist or a hearing care professional, as appropriate, for a hearing aid evaluation.

The audiologist or hearing care professional will conduct a hearing aid evaluation to assess your ability to hear with and without a hearing aid. The hearing aid evaluation will enable the audiologist or hearing care professional to select and ﬁt a hearing aid to your individual needs.

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 care professionals now oer 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. 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.

27 Warranties and repairs

ReSound provides a warranty on hearing aids in the event of defects in workmanship or materials, as described in applicable warranty documentation. In its service policy, ReSound pledges to secure functionality at least equivalent to the original hearing aid. As a signatory to the United Nations Global Compact initiative, ReSound is committed to doing this in line with environment-friendly best practices. Hearing aids therefore, at ReSound’s discretion, may be replaced by new products or products manufactured from new or serviceable used parts, or repaired using new or refurbished replacement parts. The warranty period of hearing aids is designated on your warranty card, which is provided by your hearing care professional.

For hearing aids that require service, please contact your hearing care professional for assistance. ReSound hearing aids that malfunction must be repaired by a qualiﬁed technician. Do not attempt to open the case of hearing aids, as this will invalidate the warranty.

28 Temperature test, transport, and storage information

ReSound hearing aids are subjected to various tests in temperature and damp heating cycling between

-13°F and 158°F according to internal and industry standards. During transport or storage, the temperature should not exceed the limit values of -4°F and 140°F and relative humidity of 90% RH, non-condensing (for limited time). The air pressure between 500 hPa and 1,100 hPa is appropriate.
