Getting the Most Out of Your Unison™
Hearing Instruments
Adjusting to your new hearing instruments will take
some time. In the beginning it is important that you do
not use the hearing devices for longer than is
comfortable. Depending on your previous experience
with hearing instruments, a few hours a day may be
enough and then you can increase wearing time
gradually. Once you have become accustomed to your
hearing devices, you should wear them all day everyday
since frequent use will help you adapt to your hearing
devices and enjoy their full benefits. The quicker you get
used to the everyday sounds around you, the less you
will notice that you are wearing hearing instruments.

Using the Unison™Digital ITE Guide
Refer to the table of contents for a complete listing of
the topics covered in this guide.
Use the diagram below to identify some of the
components on your hearing devices. Because each
device is custom-designed and molded to fit an
individual ear, the physical appearance and exact
positioning on your hearing devices may vary slightly
from those shown.

Turning Your Unison™Hearing
Instruments On and Off
Your Unison hearing devices may have a
volume control that also serves as an
on/off switch. To turn your hearing devices
on, rotate the volume control towards
your nose. Note: If the start up mute is activated, your
hearing devices will not turn on until the program
button is pushed.
To turn your hearing devices off, rotate the volume
control away from your nose.
For hearing devices without a volume control, close the
battery door to turn your hearing devices on. Open the
battery door or remove the battery to turn your hearing
devices off.

Inserting and Removing ITE and CIC
Hearing Instruments
ITE and CIC hearing instruments are color-coded red for
the right ear and blue for the left ear. The color is
indicated either on the shell or on a label on the hearing
device.
To insert ITEs and CICs:
1. Hold the hearing device between your thumb and
index finger with the battery door away from your ear.
2. If your hearing device is a CIC, insert by holding the
hearing device with the removal handle at the
bottom.
3. Gently insert the canal portion of the hearing device
into your ear using your index finger to push back and
tuck the hearing device completely into place.
To remove ITEs and CICs:
1. If your hearing device is a CIC, gently pull on the
removal handle. To remove ITE hearing instruments,
grasp the device with your thumb and index finger.
2. Move your jaw up and down or apply pressure to the
back of your ear to help loosen the device.
Note: Never use the volume control or the battery door
to remove your hearing devices.

Feedback-Free Listening
Your Unison hearing instruments may have an optional
start up mute that can be activated by your hearing
healthcare professional. If the start up mute is activated,
your hearing instruments will not turn on until the
program button is pushed, even if the battery door is in
the ON position. The hearing instruments return to the
start up mute position each time you turn your hearing
instruments on. This allows you to insert your hearing
instruments without experiencing whistling.
If you wear hearing instruments now, you may have
experienced whistling from your hearing instruments
when you talk, chew, use the telephone or hug
someone. Unison’s feedback technology dramatically
reduces this uncomfortable whistling before you or
anyone else can perceive it.

Operating Instructions ITE and CIC
Changing Programs on Your Unison™
Hearing Instruments
Your Unison hearing devices may have up to three
programs. Each program has been individually tailored
by your hearing healthcare professional to meet your
particular listening needs.
Unison has a push-button for switching between
programs. Each time you push the program button, you
will move to a new program. For Unison Essential, each
time you push the program button, you will move from
program 1 to the telecoil program. For Unison 3 and 6,
each time you push the program button you will move
among up to three programs. Your hearing devices beep
to indicate which program you are in (i.e. one beep for
program 1, two beeps for program 2, etc.) If you prefer,
your hearing healthcare professional can adjust the pitch
and loudness of the program beep or turn it off entirely.
Adjusting the Volume
The volume on your hearing devices may adjust
automatically in response to the loud or quiet sounds
around you. If you have a manual volume control, you
can further adjust the volume on your hearing devices.
Rotate the volume control towards your nose to
increase the volume or away from your nose to decrease
the volume. Note that your volume control may be
8

disabled by your hearing healthcare professional and,
therefore, could be inactive.
Setting Your Ideal Volume
Unison hearing instruments equipped with manual
volume control have an ideal volume indicator. A single
beep indicates when the volume control has reached its
ideal level for your particular hearing loss, as pre-set by
your hearing healthcare professional.
Listening in Quiet and Noisy Environments
Your Unison hearing devices may have a dual directional
microphone system which focuses on sounds in front of
you (i.e., speech) while reducing sounds from the sides or
behind you (i.e., noise). Your directional system is
activated by the push of the program button. Your
hearing healthcare professional will explain which
program(s) contain the directional microphones.
Using Unison™with Telecoil for the Telephone
Unison comes equipped with an optional telecoil that can
help you listen on the telephone. The telecoil program is
selected with the program button. When using the telecoil,
center the telephone receiver on the hearing device and
move the receiver along the hearing device to locate the
clearest, strongest signal. You may have to increase the
volume of your hearing device slightly. To return to normal
listening, push the program button. Your hearing device
will beep to indicate which program you are in.

Using Unison™with Easy t-coil for the Telephone
Unison can also come equipped with an optional Easy t-
coil (automatic telephone coil) that can help you listen on
the telephone. The Easy t-coil automatically switches your
hearing instrument into a telephone listening mode with
hearing instrument compatible phones. If your phone is
hearing instrument compatible, it will have a magnetic
coil and the Easy t-coil will activate automatically when
the telephone is held to the ear. Once the telephone is
removed from the ear, the hearing instrument will switch
back to the normal listening mode. Since the location and
strength of the magnetic coil varies among phone
manufacturers, it may be necessary to move the
telephone receiver slightly to find the best reception. If
the hearing instrument does not switch to telecoil
automatically when the telephone receiver is placed in
proximity, the magnet for Easy t-coil hearing instruments
should be attached to the telephone receiver. The magnet
is designed to strengthen the magnetic coil in hearing
instrument compatible telephones.
To affix the Easy t-coil magnet:
1. Clean the telephone receiver.
2. Hold the magnet near the “listening end” of your
telephone receiver and release it (figure 1). The
magnet will flip to the appropriate side and seek the
optimal position on the telephone receiver.
10

3. Place the double-sided tape in this optimal position
on the telephone receiver (figure 2) and attach the
magnet to the tape (figure 3).
Warnings
• Be sure the magnet is securely affixed to the
telephone.
• Keep loose magnets out of reach of children and pets.
• If the magnet falls into your ear, contact your hearing
healthcare professional.
• If the magnet is swallowed, contact your physician
immediately.
• The magnet may affect some medical devices or
electronic systems. Always keep the magnet (or the
telephone equipped with the magnet) at least 30 cm
(12”) away from pacemakers, credit cards, floppy
disks or other magnetically sensitive devices.
• Too high distortion during dialing or phoning may
mean that the phone handset is stressed by the
magnet. To avoid any damage, please move the
magnet to another place on the telephone receiver.

Replacing the Battery
1. Gently swing out the battery door with your
fingernail.
2. Grasp the battery with your thumb and index finger
and remove.
3. Insert the new battery into the battery door with the
plus (+) sign on the battery facing the same way as
the plus (+) sign on the edge of the battery door. This
will ensure that the battery door closes properly.
Note: If the battery is inserted incorrectly, the door will
not close.
4. Close the battery door.

Low Battery Warning
When you hear one long beep, your hearing instruments
are warning you that their batteries are low. You will
hear the warning approximately every 30 minutes until
you change the batteries or the batteries die. After the
first warning, you may experience some reduction in
sound quality. This is normal and can be remedied by
inserting fresh batteries in the hearing devices. If you
prefer, your hearing healthcare professional can change
the pitch and loudness of the low battery beep or turn it
off entirely.
Caring for Batteries
• Always discard batteries carefully.
• To prolong battery life, remember to turn your
hearing instruments off when not in use.
• Remove the batteries and keep the battery door
open while hearing instruments are not in use. This
will allow internal moisture to evaporate.
Warnings
• Never leave hearing instruments or batteries where
small children and pets can reach them.
• Never put hearing instruments or batteries in your
mouth. If a hearing instrument or battery is
swallowed, call a physician immediately.

Caring for your Unison™Hearing
Instruments
• Always remove your hearing devices when using hair
care products. The hearing devices can become
clogged and cease to function properly.
• Protect your hearing devices from excessive heat
(hair dryer, vehicle glove box or dashboard) and
moisture (bath or shower). Do not immerse the
hearing devices in water.
• If your hearing devices do become wet, do not
attempt to dry them in an oven or microwave. Do not
adjust any controls. Open the battery doors
immediately and allow your hearing devices to dry
naturally for 24 hours.
• Regular use of a dehumidifier, such as a Dri-Aid kit,
can help prevent corrosion and prolong the life of
your hearing devices. See your hearing healthcare
professional for more information.
• Do not drop your hearing devices or knock them
against hard surfaces.

15
Cleaning Your Unison™Hearing
Instruments
Ear wax is natural and common. Ensuring your hearing
instruments are free of ear wax is an important step in
your daily cleaning and maintenance routine.
• Using the brush that was provided with your hearing
instruments, clean ear wax from your hearing
instruments everyday.
• Never use alcohol to clean your hearing devices.
• Do not use sharp tools to dislodge ear wax. Sticking
household items into your hearing devices can
seriously damage them.
• Talk to your hearing healthcare professional about
regular appointments to have the wax removed from
your hearing devices.

Warnings
• Hearing instruments should only be used as directed
by your physician or hearing healthcare professional.
• Hearing instruments will not restore normal hearing
and will not prevent or improve a hearing impairment
resulting from organic conditions.
• Do not use your hearing instruments in explosion
hazard areas.
• Allergic reactions to hearing devices are unlikely.
However, if you experience itching, redness,
soreness, inflammation or a burning sensation in or
around your ears, inform your hearing healthcare
professional and contact your physician.
• In the unlikely case that any parts remain in the ear
canal after the removal of the hearing instrument,
contact a physician immediately.
• Remove your hearing devices for CT and MRI scans or
for other electromagnetic procedures.
• Special care should be exercised in wearing hearing
devices when maximum sound pressure levels
exceed 132 decibels. There may be a risk of impairing
your remaining hearing. Speak with your hearing
healthcare professional to ensure the maximum
output of your hearing devices is suitable for your
particular hearing loss.
