Inserting the Battery
1. Remove the brown colored tab from the flat, (+)
positive side of the size 312 battery. Wait one
minute for battery to reach full power before
using (or testing) battery.
2. Open battery holder gently, using your fingernail or
thumbnail. Pull out on the small lip of the battery
holder located on the lower part of the Felix-8740.
3. Locate the + symbol on the inside top rim of the
battery holder. This indicates that the flat, positive
side of the battery should face up in the same
direction as the + symbol.
4. Place the battery in the battery holder – NOT
directly inside the Felix. Fit the battery in the
holder with the flat, positive (+) side facing up.
5. Close the battery holder. NEVER force the battery
holder closed. If the holder does not close easily
then the battery is probably upside down.

You can try your Felix-8740 right away just as it is. We’ve selected the
slim-tubing that works the best for most people and encourage you
to try this size first. You will find size 1 slim-tubing attached to your
Felix-8740.
We have included an additional size slim-tubing to try if the size 1
does not fit properly.
Extra slim-tubing for Men: Extra slim-tubing for Women:
Size 2 Left and/or size 2 Right Size 0 Left and/or size 0 Right
It’s important for the slim-tubing to fit correctly: slim-tubing should
fit snugly against your ear once the Felix-8740 and eartip are in place.
If not, the slim-tubing may be too short or too long. Try a different
slim-tubing length.
Slim-tubing sizes/lengths:
There are four sizes of slim-tubing
available for the right and left ear.
Right slim-tubing: 0 R, 1 R, 2 R, 3 R
Left slim-tubing: 0 L, 1 L, 2 L, 3 L
Picturing Left ear slim-tubing: 3, 2, 1, 0
Slim Tube Choices
Removing & Attaching Slim-tube
REMOVING slim-tubing from the Felix-8740:
Grasp the thicker base of
the slim-tubing near the
top of the Felix-8740.
Twist the tubing 90
to the le or right.
Pull the thicker base
of the tubing away
from the Felix.
ATTACHING slim-tubing to the Felix-8740:
Line up the top of the Felix and the thicker tubing base
and gently push the end of the slim-tube onto the
Felix until it snaps into position.
Attention: Please make sure eartips and slim-tubing are securely
attached before using so they do not come off in your ear.

61-800-221-2099 • HearingHelp.com
Eartip choices for slim-tube style
We offer a variety of eartip options. We have attached the eartip style that we feel
works best for most. Also included are several other eartip options.
If you have trouble with the fit or the eartip or if you experience feedback (squeal),
give the other eartips a try.
How to Attach Dome Eartips:
1. Line up the narrow tubing nozzle with the opening on the inside of the eartip.
2. Push together firmly until the eartip is securely attached. Wiggle the eartip
to be certain it stays in place.
How to Remove Dome Eartips:
1. Hold the eartip tightly and grasp the tubing directly
behind the eartip. Pull firmly. (Replace eartips as needed.)
Tulip dome eartip: Designed to help reduce feedback while allowing
for better speech clarity. Provides a great fit for a wide variety of ear canal
shapes and sizes. Available in one size.
Open dome eartips: Helpful for those with a mild hearing loss and can
provide you with better speech clarity. Available in sizes small, medium and large.
Closed dome eartips: Designed to reduce feedback (squeal) if you have
more of a moderate hearing loss. Available in sizes small, medium and large.
Double dome eartips: Designed for those that struggle with feedback
(squeal) due to having a moderate to severe hearing loss or using the
hearing aid on a higher volume level. Available in sizes small, medium
and large.

Which is left and right - slim-tube style
How to tell your right Felix-8740 from your left Felix-8740:
Felix-8740 hearing aids can be used in either ear by selecting
a right slim-tubing or a left slim-tubing. Each slim-tubing
is preformed to “point” into either the right or left ear. Right slim-tubing has red
lettering on it and left slim-tubing has blue lettering (printed near the eartip).
If you’re not sure of the color, hold the Felix-8740
with the tubing attached and the volume control facing
towards you. Left tubing will point to the right and
right tubing will point to the left.
Set for
left ear.
Set for
right ear.
How to insert the Felix-8740:
1. Grasp the slim-tubing behind the eartip and gently push
the eartip into your ear canal.
2. Place your Felix-8740 over the top of your ear.
3. The slim-tubing will probably bulge slightly near the ear
canal. Point at the bend in the tubing and push gently.
The eartip should slip a little further into the ear canal for
proper placement. The tubing should fit snugly against
your ear.
Note: If pushing on the slim-tubing causes discomfort, STOP.
Call for assistance. 1-800-221-2099
4. Place the sure-lock into the bowl of your ear. The sure-lock
is the thin filament attached to the tubing. Use your finger
to secure the sure-lock into the most comfortable position.
Insert & Remove Felix-8740 - slim-tube style
To Remove Felix-8740:
1. Grasp hold of the slim-tubing against your ear and gently pull.
The eartip will slip out of your ear.
2. Remove the Felix-8740 from behind your ear.
NOTE: Tubing should not bulge away from the ear or pull the Felix down
or the eartip out of the ear. If this occurs, try a different length tubing.
ATTENTION: Confirm the eartip is attached to the slim-tubing each time you remove it from your ear.
If the eartip remains in your ear, seek medical assistance.

How to tell your right aid from your left aid:
The standard fit style of the Felix-8740 hearing aid can be used on either
ear. Once you have attached your eartip or custom earmold your hearing
aid is set for either your right or left ear. Compare your hearing aid to the
picture below. The sound opening on the eartip will “point” away from the
Felix hearing aid.

Which is left and right standard fit style
Inserting and removing standard fit style
How to insert the Felix-8740 (standard fit style):
1. Hold the tubing behind the eartip and insert into
your ear.
If using a custom earmold, make sure it is correctly
positioned in your ear. The top and bottom of the
earmold should fit securely.
2. Place the Felix behind your ear by slipping it
over the top of your ear.
Some people prefer to first place the Felix over their
ear and then insert the eartip. Experiment and find what
works best for you.
ATTENTION: Confirm the eartip is attached to the tubing each time you remove it from your
ear. If the eartip remains in your ear, seek medical assistance.

We’ve done what we can to protect your Felix-8740 from moisture and earwax but
a little regular cleaning by you will go a long way towards trouble-free use. Without
regular cleaning, wax and moisture can build up and prevent your Felix-8740 from
working properly. We suggest cleaning your Felix-8740 in the morning before you
use it and storing it overnight in a DryAid Dehumidifier (call to order). It does not
take much dirt or wax to clog the super-thin tubing and the tiny openings. Many
customers find cleaning the tubing weekly is sufficient. For best results consider
purchasing the Cleaning Care Plan (pg. 14).
Cleaning your Felix-8740:
1. Wipe off the outside of the Felix-8740 hearing aid and eartip
with a soft cloth or hearing aid cleaning wipes (call to order).
2. Use the included cleaning brush and tube cleaning tool to gently
remove wax and dirt from the hearing aid sound openings.
How to clean your Felix-8740 slim-tubing:
1. REMOVE THE SLIMTUBING from the Felix-8740 (see pg. 5).
There is no need to remove the eartip from the tubing.
2. Insert the cleaning tool into the triangular base at the
end of the slim-tubing.
3. Thread the cleaning tool all the way through the
slim-tubing and out of the end of the eartip.
4. Wipe off any debris on the end of the cleaning tool before
pulling it back through the eartip and slim-tubing.

Care and cleaning standard fit style
It's important to clean your Felix hearing aid regularly. Without regular cleaning,
wax and moisture can build up and prevent the hearing aid from working
properly. It’s best to clean your Felix-8740 in the morning before you use it.
How to clean your Felix-8740 (standard fit style):
1. Wipe off the outside of the Felix hearing
aid and the eartip with a soft cloth.
Eartips can be replaced when necessary.
2. If wax or debris remains, use a small
soft cleaning brush to gently remove it.
Cleaning Brush
IMPORTANT CARE INSTRUCTIONS
BEGINNING THE DAY: After showering,
apply all lotions, creams, hairspray,
perfume and cologne BEFORE putting
on your Felix-8740s. Water and such sprays can damage hearing aids. And please
remember, your hearing aids are sensitive and don’t like extreme heat or cold. Never
place your Felix-8740 in water. If it becomes wet, immediately remove the battery and
let your Felix-8740 stand in a dry place or DryAid dehumidifier for several hours. NEVER use
heat (blowdryer, oven, microwave, etc.) to dry your Felix.
AT THE END OF THE DAY: Open the battery door when not wearing your hearing aid.
Any moisture inside your hearing aid can then evaporate, extending the life of your
Felix-8740. With the battery door open, you can be assured your hearing aid is off
and not squealing. A squealing hearing aid can attract pets which have been known
to chew on hearing aids and damage them beyond repair. Even better, remove the
battery and store your Felix-8740 overnight in a DryAid dehumidifier.
The Felix-8740 is designed to work with an optional Bluetooth® companion
microphone. When traveling by plane, you'll need to set the Felix to "airplane mode"
to disable the connection between the companion microphone and the hearing aid.
To enable airplane mode: open the battery door, hold the volume button down
as you close the battery door.
To turn off airplane mode: open and close the battery door again (you do not
need to hold the volume button).
Airplane Mode

If your hearing aid is: WHISTLING (FEEDBACK)
1. Your Felix-8740 may briefly whistle
when a hand, hat or other object is near
it or when inserting and removing.
2. Turn the volume down, it may be set
too high (pg. 10).
3. Use program setting #3 (pg. 10).
4. Check that your eartip is inserted
correctly (slim-tube style pg. 7 –
standard fit style pg. 9).
5. Try a different size eartip (slim-tube
style pg. 6 – standard fit style pg. 8).
or call customer service for other
options.
6. Verify the tubing is attached correctly.
Slim-tubing or standard fit tubing
should be in good condition. If using
standard fit tubing verify that tubing
is soft and not cracked. If the tubing
has hardened or is damaged, it
should be replaced (slim-tube style
pg. 5 – standard fit style pg. 8).
7. Try a fresh battery.
8. If your companion microphone
is on, turn it off. If the feedback
stops, reduce the volume on your
companion microphone and move it
further away from you
1. Check that the battery is inserted
correctly (pg. 4).
2. Try a fresh battery.
3. Clean your Felix-8740, microphone
ports, and eartip (slim-tube style
pg. 11 – standard fit style pg. 12).
4. If your Felix goes dead periodically,
but comes on after several hours of
rest, the problem may be a build-up
of humidity. Try storing it in a DryAid
dehumidifier when not in use. Call
toll-free to order.
If your Felix-8740 requires service, send it to:
Hearing Help Express
1714 Sycamore Rd • PO Box 586 • DeKalb, IL 60115-0586

Precautions: A hearing aid is a precision electronic device and
as such, it requires the care in use and handling that you would
afford any fine piece of equipment. The following precautions
are not meant to discourage normal use of your hearing aid, but
are suggested to insure quality performance and long life from
your hearing aid.
Do not drop or throw your hearing aid, as this may damage
internal components. Do not expose your hearing aid or batteries
to excessive heat, such as from stove tops, hair dryers, heat
lamps or your automobile rear shelf or glove compartment. Do
not immerse your hearing aid in water or other liquids, or wear it
while bathing, showering or swimming. If your hearing aid is to
be stored for any length of time, be sure to remove the battery
and store both in a cool, dry place. Your hearing aid has been
constructed from the finest materials, using the latest engineering
technology; however, in rare instances, an individual may exhibit
signs of skin irritation, allergic reaction, or accelerated accumulation
of cerumen (earwax). If this occurs, consult your physician.
Keep new and used batteries out of reach of children
and those with diminished mental capacity. Batteries, if
consumed, can be harmful. Consult your physician
immediately and call the National Battery Hotline
collect [phone].
Important notice for prospective hearing device 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 device. 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 identied
and treated before the hearing device 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 device.The physician will refer you to an audiologist or
a hearing device dispenser, as appropriate, for a hearing device
evaluation.The audiologist or hearing device dispenser will
conduct a hearing device evaluation to assess your ability to hear
with and without a hearing device.The hearing device evaluation
will enable the audiologist or dispenser to select and t a hearing
device to your individual needs.
If you have reservations about your ability to adapt to ampli-
cation, you should inquire about the availability of a trial-rental
or purchase-option program. Many hearing device dispensers
now oer programs that permit you to wear a hearing device for
a period of time for a nominal fee after which you may decide if
you want to purchase the hearing device. Federal law restricts the
sale of hearing device 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.
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.
Warning to Hearing Aid Dispensers: A hearing aid dispenser
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 aid dispenser 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:
Warning Signs:
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 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.
NOTE: Special care should be exercised in selecting and fitting a
hearing aid whose maximum sound pressure level exceeds 132
decibels because there may be a risk of impairing the remaining
hearing of the hearing aid user.
Hearing with Your New Amplification The world will seem
noisier at first, but in time, you should become accustomed to your
new listening experiences, learn to hear speech more clearly, and
enjoy many of the special sounds you may have been missing.
Obtaining maximum benefit from your new hearing aid(s)
requires effort and practice on your part. Your new hearing aid(s)
will not restore normal hearing and will not prevent or improve
hearing impairment resulting from organic conditions. In most
cases, infrequent use of the hearing aid(s) will not permit you to
obtain full benefit from it. Follow the program recommended by
your hearing professional. The use of your hearing instrument(s)
is only part of your hearing rehabilitation, and you may need
supplemental auditory training and instructions in lipreading.

1. Start Slowly – Begin by using your new hearing aid a few hours a day
while you are alone. If you're not used to wearing a hearing aid, you will
probably notice many sounds you have not heard in a while. And while you
may enjoy the sounds of birds again, other sounds like crackling paper and
the refrigerator running may take some time to get used to. With practice you
should be able to focus on the sounds you want to hear and ignore the rest.
Hearing aids will not restore your hearing, but they absolutely can help.
2. Read Out Loud – Your own voice will sound strange at first. Try reading out
loud for 15 minutes a day to get used to the sound of your voice.
3. Practice Listening to One Voice – Start in a quiet environment listening to
the radio or your favorite TV show. Then practice listening with one friend or
family member at a time.
4. Listen and Talk in Small Groups – Next try talking with a small group of
people, first in a quiet setting and then in a noisier environment. Remember,
most people have difficulty understanding in loud places with background
noise. So, be patient and keep practicing. Your understanding should
improve with time.
