Prescription use of this TSG hearing instrument
The TSG module should be used as prescribed by your doctor, audiologist or hearing healthcare profes-
sional. In order to avoid permanent hearing damages, the maximum daily usage depends on the level of
the generated sound.
Should you develop any side effects from using the sound generator, such as dizziness, nausea, head-
aches, 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 re-
quire training by a doctor, audiologist, hearing healthcare professional or the guardian for the insertion and
removal of the hearing instrument containing the TSG module.
Important notice for prospective sound generator users
A tinnitus masker is an electronic device intended to generate noise of sufficient 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 affect 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 counselling and/
or in a tinnitus management programme to relieve patients suffering from tinnitus.

Getting started
On/Off function
1. When the battery door is closed, the hearing instrument turns on, and the default programme will be
activated.
2. To turn off the hearing instrument, open the battery door. Many individuals can use their fingernail to
pull it open.
SmartStart
Hearing instruments can be turned on once you have placed them on
your ears. If you prefer to turn them on just prior to placing them on your
ear, your hearing care professional can activate a function called Smart-
Start. This function will delay the time in which the hearing instruments
turn on after the battery compartment is closed. With SmartStart, a beep
will be heard for each second of the delay period.
Inserting/Replacing the battery
1. Open the battery door completely by using your
fingernail. Remove the used battery if present.
2. Prepare the new battery (please refer to page 6 for
information on appropriate battery type/size for your
hearing instrument). Remove the protective foil and
wait 2 minutes before inserting the battery into the
hearing instrument to allow activation of the battery.
3. Insert the new battery with the positive side in the
correct position.
4. Gently close the battery door.
iTip:
1. Always use new Zinc-Air batteries that have a minimum remaining shelf life of 1 year.
2. Whenever the hearing instruments are not in use, remember to turn them off to avoid unnecessary
battery consumption.
3. Remove the sticker from the battery and let it air for 2 minutes before you insert it.
4. If hearing instrument is experiencing frequent loss of connection to ReSound Unite accessories, contact
your hearing care professional for a list of low impedance batteries.

14 15
Low battery indicator
Your hearing care professional can activate a low battery indicator in your hearing instruments. The hear-
ing instrument will reduce amplification and play a melody if battery power gets too low. This signal will
recur every 15 minutes until the hearing instrument automatically switches off. The timing of the low battery
indicator can vary slightly, depending on the type of battery used. It is recommended that you keep spare
batteries on hand.
Low battery indicator when paired with wireless accessories only
Active usage of the ReSound Unite accessories (Remote Control 2, Phone Clip+, TV Streamer 2 and Mini
Microphone) or an FM receiver requires more battery power from the hearing instruments than when they
are working without accessories which means that battery life is highly dependent on the amount of wire-
less accessory usage. When the battery in the hearing instrument has depleted to a level at which use of
ReSound Unite TV Streamer 2, Phone Clip+ and Mini Microphone cannot be supported, the hearing instru-
ment will play two sets of descending tones.
After this, your hearing instrument and ReSound Unite Remote Control 2 will continue to work as usual, but
you will not be able to use your ReSound Unite TV Streamer 2, Phone Clip+ and Mini Microphone. At some
point the battery level will also be too low to support the remote control as well and you will once again
hear the descending tones. The hearing instruments will continue to work as usual. Once a new battery is
inserted, full operation of the accessories will resume.
Inserting/Removing hearing instruments
Insertion (custom earmoulds)
1. Hold the earmould between your thumb and index finger and position its
sound outlet in your ear canal.
2. Slide the earmould all the way into your ear with a gentle, twisting movement.
3. Turn the top part of the earmould gently backwards and forwards so that it
tucks behind the fold of skin above your ear canal.
4. Move the earmould up and down and gently press to ensure it is positioned
correctly in the ear. Opening and closing your mouth can ease insertion.
5. Make sure the hearing instrument is seated behind the ear.

16 17
By experimenting, an easier method may be discovered. With proper insertion, hearing instruments should
fit snugly but comfortably. If the hearing instruments cause irritation of the ears, contact your hearing care
professional.
iNote: Never attempt to modify the shape of the hearing instrument, earmoulds, or tubing yourself.
iTip: It may be helpful to pull your ear up and outward with your opposite hand during insertion.
Removal (custom earmoulds)
1. Hold a portion of your earmould towards the back of the ear.
2. Pull the earmould outward and simultaneously rotate the earmould forward.
3. Consult your hearing care professional if you have difficulties removing the hearing instrument.
Insertion (domes/custom earmoulds with thin tubes)
1. Place the hearing instrument on the ear.
2. Hold the thin tube where it bends, and gently
place the dome into the ear canal. Push the dome
far enough into the ear canal so that the thin tube
lies flush with the head.
3. It is important that the tube and the dome fit
correctly into your ear.
4. When the dome is placed correctly, you should not be able to see the thin tube sticking out when facing
a mirror.
iNote: You should never attempt to bend or modify the shape of the thin tube.
Removal (domes/custom earmoulds with thin tubes)
1. Hold the thin tube with your thumb and forefinger and remove the tube.
2. For thin tube custom earmoulds, grasp the removal string and pull the earmould
outward.
3. Consult your hearing care professional if you have difficulties removing the hearing
instrument.

18 19
Operation of the hearing instrument
Volume control (optional)
The volume control will allow the volume of hearing instruments
to be increased or decreased.
1. To increase the volume, push the volume control up.
2. To decrease the volume, push the volume control down.
When volume is increased or decreased, a beep signal will be heard
for each incremental change. When the upper or lower limits of the
volume range are reached, a beep signal with a lower pitch will be
heard.
If you have two hearing instruments with the synchronization function enabled, volume control adjustments
to one instrument will automatically repeat in the second instrument. When a volume control adjustment
is made in one instrument, you will hear a confirmation beep. A beep in the second instrument will follow.
Your hearing care professional can disable the volume control function if it is not desired. The volume con-
trol can also be replaced with a non-functional cover.
Programme button
Depending on your experience level with hearing instruments, in-
dividual hearing needs, and the type of listening environments you
experience, your hearing care professional may activate additional
programmes. If additional programmes have been activated, the fol-
lowing list explains how they work.
Programme Description of when to use
1

1. You can switch between programmes by pushing the push button once.
2. You will then hear one or more beeps. The number of beeps indicates which programme you have
selected (one beep = programme one, two beeps = programme two, etc.).
3. When the hearing instruments are turned off and then back on, the hearing instrument always returns
to the default setting (programme one).

20 21
If you have two hearing instruments with the synchronization function enabled, programme changes to one
instrument will automatically repeat in the second instrument. When a programme change is made in one
instrument, you will hear the same amount of confirmation beeps in the second instrument.
iFlight mode
When boarding a flight or entering an area where RF transmitters are prohibited, wireless functional-
ity must be deactivated, as it is not allowed to radiate radio signals during flights or in otherwise restricted
areas.
For LiNX2wireless hearing instruments follow the following instructions to enter and leave flight
mode:
It is possible to disable wireless operation by opening and closing the battery compartment three times
within a ten second period (open-close, open-close, open-close). Your instruments will now be in flight
mode.
If the hearing instrument is in flight mode, the hearing instrument must have been operating in flight mode
for at least 10 seconds before attempting to enable wireless again. It is possible to re-enable wireless
operation by opening and closing the battery door once. 10 seconds after this operation is completed,
wireless operation will begin again.
iNote: It is important to wait an additional 15 seconds after wireless function resumes before open-
ing and closing the battery compartment again for any reason. If the battery compartment is opened and
closed during this 15 second window, flight mode will resume.

22 23
Telephone use
Finding the optimal position for holding a telephone may require practice for some
individuals, and one or more of the following suggestions may be helpful.
1. Hold the telephone as you would normally.
2. Hold the telephone towards the top of the ear (closer to where the microphones
are).
3. If whistling occurs, it may take a few seconds of holding the telephone in the
same position before the hearing instrument eliminates the feedback.
4. Any whistling may also be decreased by holding the telephone slightly away
from the ear.
5. Depending on your individual needs, your hearing care professional may activate a programme
specifically for telephone use.
Listen to radio or TV
When listening to the TV or the radio, start out by listening to news commentators since they usually speak
clearly, then try other programmes. If you find it difficult to listen to TV or radio, your hearing care profes-
sional will be able to give you advice on available wireless accessories to enhance your listening capabilities
for TV and radio.
Using ReSound Hearing Instruments with iPhone®, iPad®, and iPod
touch®(ReSound LiNX2)
ReSound LiNX2is a Made for iPhone instrument and allows for direct communication and control with an
iPhone, iPad, or iPod touch. For assistance in pairing and using these products with your ReSound LiNX2
device, please contact your hearing care professional or visit our support site at resound.com/linx.
Cellular phones
Your hearing instrument is designed to comply with the most stringent Standards of International Electro-
magnetic Compatibility. However, not all cell phones are hearing instrument compatible. The varying degree
of disturbance can be due to the nature of your particular cellular phone or
of your wireless telephone service provider.
If you find it difficult to obtain a good result while using your cellular phone,
your hearing care professional will be able to give you advice on available
wireless accessories to enhance listening capabilities.
PhoneNow
The PhoneNow function, allows your hearing instrument to automatically switch to your telephone pro-
gramme when a telephone receiver is raised to the ear. When the telephone receiver is removed from the
ear, the hearing instrument automatically returns to the previous listening programme.

24 25
Placement of PhoneNow magnets
Place PhoneNow magnet on your telephone receiver to allow operation of the PhoneNow function. In order
to place PhoneNow magnet properly:
1. Clean the telephone receiver thoroughly.
2. Hold the telephone vertically, in a position similar to when making a telephone call.
3. Place the magnets just below the telephone receiver. Make sure not to cover the microphone openings.
If necessary, move the magnet to another position to improve ease of use and comfort while speaking.
4. If you are not satisfied with the strength of PhoneNow, you can reposition the PhoneNow magnet or add
additional PhoneNow magnets.
PhoneNow usage
Telephones can be used in a normal manner. A short melody will indicate that the PhoneNow feature has
automatically switched the hearing instrument to your telephone programme. Initially, you may need to
move the telephone receiver slightly to find the best position for reliable PhoneNow activation and good
hearing on the telephone.
If you have two hearing instruments with the synchronization function enabled, the volume of hearing instru-
ment on the non-phone ear will be turned down.
iOnly use recommended cleaning agent to clean the telephone prior to placing the magnet on the
phone in order to obtain best possible adherence.
iPhoneNow warnings
1. Keep magnets out of reach of pets, children and people with mental disabilities. If a magnet is swallowed,
please seek advice from a medical practitioner.
2. The magnet may affect some medical devices or electronic systems. The manufacturer of any
magnetically sensitive devices (e.g. pacemakers) should advise you regarding appropriate safety
precautions when using your hearing instrument and magnet in close proximity to the medical device
or electronic system in question.If the manufacturer cannot issue a statement, we recommend keeping
the magnet or a telephone equipped with the magnet 30 cm (12”) away from magnetically sensitive
devices (e.g. pacemakers).
iPhoneNow precautions
1. High distortion during dialing or phoning may mean that the magnet is not in the optimal position relative
to the telephone receiver. To avoid the issue, please move the magnet to another place on the telephone
receiver.
2. Only use magnets supplied by ReSound.

Telecoil (optional)
A telecoil can be activated by your hearing care professional and accessed through one of the additional
programmes. A telecoil picks up a telephone’s magnetic signal and converts it to sound. An optional tele-
phone programme may help to improve speech understanding on the telephone. When using a telecoil
programme, the receiver of the telephone may need to be held closer to the hearing instrument. The hand-
set of the telephone may need to be moved to slightly different positions in order to find the best reception.
Tele-loop systems
Many places, such as theatres, houses of worship, and schools are equipped with tele-loop systems. When
using a telecoil programme with tele-loop systems, sound is picked up directly and may improve speech
understanding. If there is no sound from the hearing instruments in a tele-loop system and with a telecoil
programme activated, the tele-loop system may not be turned on or is not operating correctly. If a facility is
not equipped with a tele-loop system, sitting as close as possible to the front may be helpful.
FM and Direct audio input (optional)
An FM system can greatly improve speech understanding in many situations such as when a speaker is a
long distance away or a room is noisy or reverberant. The direct audio input (DAI) can be used with a univer-
sal FM receiver or together with a cable to connect to a radio, computer or television. The sound source is
connected to the hearing instruments by a cable or a wireless FM system to the audio boot. This accessory
connects to the bottom of the hearing instruments, and once properly clicked into place, the hearing instru-
ments switches to DAI automatically.

iCare and maintenance
Please follow the following instructions to prolong the durability of your hearing instruments:
1. Keep your hearing instrument clean and dry. Wipe the case with a soft cloth or tissue after use to remove
grease or moisture. Do not use water or solvents, as these can damage the hearing instrument(s).
2. Never immerse hearing instruments in water or other liquids, as liquids may cause permanent damage
to the hearing instruments.
3. Avoid rough handling of hearing instruments or dropping them on hard surfaces or floors.
4. Do not leave hearing instruments in or near direct heat or sunlight, such as in a hot, parked car, as
excessive heat can cause damage or deform the casing.
5. Do not wear your instrument while showering, swimming, in heavy rain or in a moist atmosphere such
as a steam bath or sauna.
6. If your instrument does get wet, or if it has been exposed to high humidity or perspiration, it should be
left to dry out overnight with the battery out and the battery compartment open. It is also a good idea to
put the instrument and battery in a sealed container together with a drying agent (desiccator) overnight.
Do not use the instrument until it is completely dry. Consult your hearing care professional as to which
drying agent to use.
7. Remove your hearing instrument when applying such things as cosmetics, perfume, aftershave, hair
spray, and suntan lotion. These might get into the instrument and cause damage.
iDaily maintenance
It is important to keep your hearing instrument clean and dry. On a daily basis, clean
the hearing instruments using a soft cloth or tissue. In order to avoid damage due to
humidity or excessive perspiration, the use of a drying kit is recommended.
iCleaning earmoulds
1. Remove the earmould and attached tubing from the hearing instruments prior
to cleaning.
2. Clean the earmould using a mild soap, and rinse with lukewarm water.
3. After cleaning, dry earmoulds thoroughly and remove any residual water and
debris from the tubing utilising an air bulb and wire loop.
iNote: Earmould tubing may become stiff, brittle, or discoloured over time. Con-
tact your hearing care professional regarding tube changes.
iCleaning thin tubes and domes
1. Remove thin tubes from hearing instruments before cleaning by
unscrewing them counter clockwise.
2. Wipe down thin tubes and domes with a damp cloth.
3. In order to clear the thin tube of moisture and debris, push the black cleaning
rod through the thin tube, beginning at the end opposite the dome.

12
32 33
Note: Thin tube and dome systems should be changed every three months or sooner, should the compo-
nents become stiff or brittle.
How to apply domes
It is recommended that your hearing care professional change domes, as incorrect dome replacement
could result in the dome falling out in the ear.
ReSound Standard domes
1. Push the new dome over the ribs on the thin tube.
2. Make sure that the new dome is properly and securely mounted.
ReSound Tulip domes
Tulip domes are mounted in a similar manner to standard domes, but a few extra steps are required. Tulip
domes consist of two “petals”. It is important to note that the largest petal is the outermost petal. To ensure
this:
1. Push the largest petal away from
the thin tube using a finger. This bends the
petal forward.
2. Then push the largest petal back,
and it will be placed on top of the smaller
petal.
Using ReSound hearing instruments with smart phone apps
iIntended use of smart phone apps:
GN ReSound smart phone apps are intended to be used with GN ReSound wireless hearing aids. GN Re-
Sound smart phone apps send and receive signals from the GN ReSound wireless hearing aids via smart
phones for which the apps have been developed.
Use with smart phone apps:
• Notifications of app updates should not be disabled, and it is recommended that the user installs all
updates to ensure that the app will function correctly and will be kept up to date.
• The app must only be used with GN ReSound devices for which it is intended, and GN ReSound take
no responsibility if the app is used with other devices.
• If you would like a printed version of the user guide for a smart phone app please consult customer sup-
port or our website to obtain a printed user guide.

34 35
iGeneral precautions
1. When wireless function is activated, the device uses low-powered digitally coded transmissions in
order to communicate with other wireless devices. Although unlikely, nearby electronic devices may be
affected. In that case, move the hearing instrument away from the affected electronic device.
2. When using wireless functionality and the devices are affected by electromagnetic interference, move
away from the source.
3. Use only original GN ReSound consumables e.g. tubes and domes.
4. Never attempt to modify the shape of the hearing instrument, earmoulds, or tubing yourself.
5. Only connect ReSound hearing instruments to ReSound accessories intended and qualified to be used
with ReSound hearing instruments.
iGeneral warnings
1. Consult a hearing care professional if you think there may be a foreign object in your ear canal, if you
experience skin irritation, or if excessive ear wax accumulates with the use of the hearing instrument.
2. Different types of radiation, from e.g. NMR, MRI, or CT scanners, may damage hearing instruments. It
is recommended not to wear hearing instruments during these or other similar procedures. Other types
of radiation, such as burglar alarms, room surveillance systems, radio equipment, mobile telephones,
contain less energy and will not damage hearing instruments. However, they have the potential to
momentarily affect the sound quality or temporarily create strange sounds from hearing instruments.
3. Do not wear hearing instruments in mines, oil fields, or other explosive areas unless those areas are
certified for hearing instrument use.
4. Do not allow others to use your hearing instruments. This may cause damage to the hearing instruments
or to the hearing of the other individual.
5. Instrument usage by children or mentally challenged persons should be supervised at all times to
ensure their safety. The hearing instrument contains small parts that could be swallowed by children.
Please be mindful not to leave children unsupervised with this hearing instrument.
6. Hearing instruments should be used only as prescribed by your hearing care professional. Incorrect
use may result in hearing loss.
7. Warning to hearing care professionals: Special care should be exercised in selecting and fitting hearing
instruments with maximum sound pressure level that exceeds 132dB SPL with an IEC 60711:1981
occluded ear simulator. There may be a risk of impairment of the remaining hearing.
8. Be careful when boarding flights to deactivate the wireless functionality. Turn off your wireless
functionality by using the flight mode in areas where radio frequency emission is prohibited.
9. If device is broken, do not use.
10. External devices connected to the electrical input must be safe according to the requirements of IEC
60601-1-1, IEC 60065, or IEC 60950-1, as appropriate (wired connection, f.ex. HI-PRO), SpeedLink).

Tinnitus Sound Generator (TSG) module
Intended use for the TSG module
Your ReSound hearing instruments includes the Tinnitus Sound Generator function, a tool for generating
sounds to be used in tinnitus management programmes to relieve suffering from tinnitus.
The Tinnitus Sound Generator 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 instrument programme and the environment you are in, you will sometimes hear the
therapeutic sound resembling a continuous or fluctuating humming.
User instructions for the TSG module
Description of the device
The Tinnitus Sound Generator (TSG) Module is a software tool that generates sounds to be used in tinnitus
management programmes to relieve suffering from tinnitus.
Explanation of how the device functions
The TSG module is a frequency and amplitude shaped white-noise generator. Noise signal level and fre-
quency characteristics can be adjusted to the specific therapeutic needs as determined by your doctor,
audiologist or hearing healthcare professional.
Your doctor, audiologist or hearing healthcare 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.
Modulation level and speed can also be configured to your likes and needs. If your tinnitus troubles you only

in quiet environments, your doctor, audiologist or hearing healthcare 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 healthcare professional will review with you the
need for having such a control.
TSG volume control
The sound generator is set to a specific loudness level by the hearing healthcare professional. When switch-
ing 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 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 tin-
nitus 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 tem-
porary relief by introducing a more pleasant and controllable sound source.
