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 serve you in better communication for many
years.
Ask your hearing care professional if you have any questions.
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 your hearing aid provides 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. It may help to begin by wearing your hearing aid for short
periods – even as little as 15 minutes – and then gradually increasing your wearing time. In a way, it
is no dierent from adjusting to contact lenses. Speak to your hearing care professional, who can
design a schedule tailored just for you.
• As you get more comfortable with them, increase the wearing time and wear your hearing aids in
multiple types of listening environments.
It may take as long as several months for your brain to get used to all the “new” sounds around you. Fol-
lowing these suggestions will give your brain time to learn how to interpret amplification and increase
the benefits you get from using ReSound hearing aids.

However, the volume control (if present) allows you to adjust the volume of your hearing aids to your
liking.
1. To increase the volume, turn the
volume control up.
2. To decrease the volume, turn the
volume control down.
When you change the volume, the hearing
aid responds with a beep. When you reach
the upper or lower limits, the hearing aid
responds with a low-pitched beep.
iNOTE: If you have two hearing aids with the Synchronised Volume Control function enabled,
volume control adjustments to one hearing aid automatically repeats in the second hearing aid.
When you change the volume on one of the hearing aids, it responds with one or more beeps. A
beep in the second aid follows.
NOTE: If your hearing aids support wireless Remote Control, you may use the Remote Control 2 or
the smart phone app to adjust e.g. the volume.
7.5.2 Push button (optional)
Your hearing aid has a program button allowing you to use up to four dierent listening programs. The
list on page 2 tells which programs have been enabled.
1. Tap the program button to switch between programs.
2. You will then hear one or more beeps. The number of beeps
indicates which program you have selected (one beep =
program one, two beeps = program two, etc.).
3. When you turn the hearing aids o and then back on, they
always return to the default setting (program one and pre-
set volume).
iNOTE: If you have two hearing aids with the Synchronized Push Button enabled, program changes
to one hearing aid automatically repeats in the second hearing aid. When you change a program
in one hearing aid, it responds with one or more beeps. The same number of confirmation beeps
in the second aid follows. This Synchronized Push Button can also be configured to allow one side
to control volume increase and the other side to control volume decrease. The volume changes to
one hearing aid are repeated on the other side to keep the levels the same.

2524
8 Telephone use
Your hearing aid allows you to use the telephone as you ordinarily do. Finding the optimal position for
holding a telephone may require practice. One or more of the following suggestions may be helpful:
1. Hold the telephone up to your ear.
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 aid eliminates the feedback.
4. Whistling may stop by holding the telephone slightly away from the
ear.
iNOTE: Depending on your individual needs, your hearing care profes-
sional may activate a program specifically for telephone use.
8.1 Using ReSound Smart Hearing Aids with iPhone®, iPad®, and iPod touch®(optional)
ReSound Forte and ReSound Vida are Made for Apple, and allow for direct communication and control
with an
iPhone®, iPad®, or iPod touch®.
iNOTE: For assistance with pairing and using these products with your ReSound hearing aids,
please contact your hearing care professional.
8.2 Using ReSound hearing aids with smart phone apps (optional)
Use with smart phone apps:
• Notifications of app updates should not be disabled, and it is recommended that you install up-
dates to ensure that the app will function correctly and will be kept up to date.
• The app must only be used with ReSound devices for which it is intended, and ReSound takes 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 cus-
tomer support or go to our website at future-resound.com.
8.3 Cellular phones
Your hearing aid complies with the most stringent Standards of International Electromagnetic Compat-
ibility. However, not all cell phones are hearing aid compatible (HAC).
Any degree of disturbance can be due to the nature of your particular cellular phone or of your wireless
telephone service provider.
iNOTE: If you find it dicult to obtain good results while using your cellular phone, your hearing
care professional will be able to give you advice on available wireless accessories to enhance listen-
ing capabilities.

2726
8.4 Phone Now (not for Invisible-In-Canal)
The Phone Now function automatically switches your present listening program to your telephone
program when a telephone receiver, equipped with a magnet, is close to your ear. When you remove the
telephone receiver from your ear, the hearing aid automatically returns to the previous listening program.
8.4.1 Placement of Phone Now magnets
Place Phone Now magnet on your telephone receiver to allow operation of the Phone Now function. In
order to place Phone Now 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.
iNOTE: If you are not satisfied with the strength of Phone Now,
you can reposition the Phone Now magnet or add additional Phone Now magnets.
NOTE: Prior to placing the magnet on the telephone or cell phone, use a recommended cleaning
agent to clean the telephone.
8.4.2 Phone Now usage
1. Use your telephone in a normal manner.
2. A short melody indicates that the Phone Now feature has automatically switched on the tel-
ephone program.
iNOTE: Initially, you may need to move the telephone receiver slightly to find the best position for
reliable Phone Now activation and good hearing on the telephone.
If you have two hearing aids with enabled Comfort Phone functionality the hearing aid on the non phone
ear automatically reduces the volume.
8.5 Telecoil (optional)
Your hearing aid may be equipped with a telecoil. The Telecoil program may help to improve speech
understanding with Hearing Aid Compatible telephones and in theatres, cinemas, houses of worship etc.
that has teleloop installed.
The telecoil cannot work without a teleloop (a.k.a. induction-loop) or a Hearing Aid Compatible (HAC)
telephone. When you switch on the Telecoil program, your hearing aids pick up signals from the teleloop
or HAC telephone.
iNOTE: If you are having trouble hearing with the teleloop, ask your hearing care professional to
adjust the program.
NOTE: If there is no sound from the hearing aids in a teleloop system and an active Telecoil pro-
gram, the teleloop system may not be turned on or is not operating correctly.

2928
8.5.1 Teleloop systems
To use teleloop 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 induction loop. Look for
signs or move to another location.
3. If needed, adjust the volume.
4. When you leave, switch to program 1.
8.5.2 HAC Telephone
The telecoil picks up the HAC telephone’s telecoil signal and converts it to sound.
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 behind your ear – 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 program 1.
iNOTE: 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.
8.6 Flight mode (optional)
iWARNING: When boarding a flight or entering an area where RF transmitters are prohibited, wire- less functionality must be deactivated.
Your ReSound hearing aid allows you to control it from your smart phone or Remote Control 2. However,
in some areas you are requested to turn o wireless communication.
Follow these steps to turn o wireless mode:
1. For each hearing aid, open and close (open-close, open-close, open-close) the battery door three
times within a 10-second period.
2. Double-dings for ten seconds ( etc.) indicate that your hearing aid is in Flight mode.
Follow these steps to activate wireless mode:
1. For each hearing aid, open and close the battery door once.
2. Your hearing aids are in wireless mode after 10 seconds.
iNOTE: Both hearing aids must be set in Flight mode - even with synchronisation enabled.
NOTE: It is important to wait an additional 15 seconds after wireless function resumes before

such as a steam bath or sauna.
6. If your hearing aid 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 door open. It is also a
good idea to put the hearing aid and battery in a sealed container together with a drying agent
(desiccator) overnight. Do not use the aid until it is completely dry. Consult your hearing care
professional as to which drying agent to use.
7. Remove your hearing aid when applying cosmetics, perfume, aftershave, hair spray, and suntan
lotion. These might get into the aid and cause damage.

10.1 iDaily maintenance
It is important to keep your hearing aid clean and dry. On a daily basis, clean the hearing aids 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.
10.2 Replacing wax filters
Custom hearing aids may have wax filters that protect against wax and moisture. It is recommended that
these are changed as needed.
10.2.1 Change HF3 wax filters
1. Brush the sound outlet area with the sound outlet pointed down.
2. Insert the threaded end of the wax filter tool into the used wax filter, and gently rotate clockwise.
3. Gently pull until the used filter is removed.
4. Discard the used filter in the slot located in the wax filter kit by pressing it into the centre, sliding it
to one end of the slot, and pull until the filter is discarded.
5. Flip the wax filter tool around, locate a new filter in the dial, and press the tip of the tool into the
center of the dial.
6. Gently pull the new filter out of the dial.
7. Align the new filter to the sound outlet.
8. Press the new filter into the opening, and simultaneously pull and rock back and forth until the
new wax filter is in place.
10.2.2 Change Cerustop (white) wax filters
1. To remove the old wax guard, insert the removal side of the wax guard tool into the used wax
guard so that the shaft of the tool is touching the rim of the wax guard. Slowly pull the wax guard
straight out.
2. To insert the new wax guard, gently press the replacement side of the wax guard tool straight into
the hole of the sound outlet until the outer ring lies flush with the outside of the receiver. Pull the
tool straight out -the new wax guard will remain in place.
iTIP: Pressing on the new filter with the flat side of the wax filter tool can ensure that the filter is
correctly in place.
NOTE: If a dierent type of wax filter is used for your hearing aids, or if your hearing aids do not
use wax filters, consult your hearing care professional for guidance.
iCAUTION: Use only original ReSound consumables e.g. wax filters.

11 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 earwax accumulates with the use of the hearing aid.
2. Dierent types of radiation, from e.g. NMR, MRI, or CT scanners, may damage hearing aids. It is
recommended not to wear hearing aids 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 aids. However, they have the potential to mo-
mentarily aect the sound quality or temporarily create undesired sounds from hearing aids.
3. Do not wear hearing aids in mines, oil fields, or other explosive areas unless those areas are certi-
fied for hearing aid use.
4. Do not allow others to use your hearing aids. This may cause damage to the hearing aids or to the
hearing of the other individual.
5. Hearing Aid usage by children or mentally disabled persons should be supervised at all times
to ensure their safety. The hearing aid contains small parts that could be swallowed by children.
Please be mindful not to leave children unsupervised with this hearing aid.
6. Hearing aids should be used only as prescribed by your hearing care professional. Incorrect use
may result in sudden and permanent hearing loss.
7. Warning to hearing care professionals: Special care should be exercised in selecting and fit-
ting hearing aids 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 o 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, IEC 60065, or IEC 60950-1, as appropriate (wired connection, for example HI-PRO),
SpeedLink).
i1. ReSound wireless devices include a RF transmitter that operates in the range of 2.4 GHz - 2.48
GHz.
2. Nominal RF output power transmitted is 0 dBm.
3. For use of wireless functionality only use wireless accessories. For further guidance regarding
e.g. pairing, please refer to the user guide of the relevant wireless accessory.

12 iUsing ReSound hearing aids with ReSound apps for smart
phones
12.1 Intended use of ReSound apps for smart phones:
ReSound smart phone apps are intended to be used with ReSound wireless hearing aids. ReSound smart
phone apps send and receive signals from the ReSound wireless hearing aids via smart phones for which
the apps have been developed.
12.2 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 aected. In that case, move the hearing aid away from the aected electronic device.
2. When using wireless functionality and the devices are aected by electromagnetic interference,
move away from the source.
3. Use only original ReSound consumables e.g. tubes and domes.
4. Only connect ReSound hearing aids to accessories intended and qualified to be used with
ReSound hearing aids.
13 iPhone Now 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 aect 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 aid 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 magneti-
cally sensitive devices (e.g. pacemakers).
13.1 iPhone Now precautions
1. High distortion during dialing or phoning may mean that the magnet is not in the optimal posi-
tion 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.

14 iBattery warnings
Batteries contain dangerous substances and should be disposed of carefully in the interest of your safety
and for the environment. Please note:
1. Keep batteries away from pets, children and mentally challenged persons.
2. DO NOT place batteries in your mouth. Consult a physician immediately if a battery has been
swallowed, as they can be harmful to your health.
3. Do not attempt to recharge batteries (Zinc Air) which are not specifically designated as recharge-
able because they may leak or explode.
4. DO NOT attempt to dispose of batteries by burning them.
5. Used batteries are harmful to the environment. Please dispose of them according to local regula-
tions or return them to your hearing care professional.
6. Remove the batteries to prevent leakage when the hearing aids are not in use for an extended
period of time.
15 iHearing 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 audi-
tory training and instructions in lip-reading.
16 iWarning to hearing aid hearing care professionals (US Only)
A hearing care professional should advise a prospective hearing aid user to consult promptly with a
licensed physician (preferably an ear specialist) before dispensing a hearing aid if the hearing care
professional determines through inquiry, actual observation, or review of any other available information
concerning the prospective user, that the prospective user has any of the following conditions:
1. Visible congenital or traumatic deformity of the ear.
2. History of active drainage from the ear within the previous 90 days.
3. History of sudden or rapidly progressive hearing loss within the previous 90 days.
4. Acute or chronic dizziness.
5. Unilateral hearing loss of sudden or recent onset within the previous 90 days.
6. Audiometric air-bone gap equal to or greater than 15 decibels at 500 Hertz (Hz), 1,000 Hz, and
2,000 Hz.
7. Visible evidence of significant cerumen accumulation or a foreign body in the ear canal.
8. Pain or discomfort in the ear.
