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 instruments. Because each
instrument 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
instruments on, rotate the volume control
towards your nose. Note: If the start up mute is
activated, your hearing instruments 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 devices 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 devices, 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 devices 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 devices will not turn on until the program
button is pushed, even if the battery door is in the ON
position. The hearing devices return to the start up mute
position each time you turn your hearing devices on.
This allows you to insert your hearing devices without
experiencing whistling.
If you wear hearing devices now, you may have
experienced whistling from your hearing devices 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 instruments 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 instruments
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 instruments 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
instruments. Rotate the volume control towards your
nose to increase the volume or away from your nose to
8

9
decrease the volume. Note that your volume control
may be 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 instruments may have a dual
directional microphone system which focuses on
sounds in front of you (e.g., speech) while reducing
sounds from the sides or behind you (e.g., 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 tcoil (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 device compatible phones. If your phone is
hearing device 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
device 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
10

magnet will flip to the appropriate side and seek the
optimal position on the telephone receiver.
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
