Note:
Everyone's ear canals are shaped differently. In fact, it is not
uncommon for the left and right ear canals to bend in different
directions, even in the same person. If you feel light resistance
when you first insert the D30 device, and it doesn't feel like it has
gone in all the way, the D30 device might just need a little help.
Give it a little nudge left, right, up, or down to see if you have a
bend in your ear canal, and if you can, nudge it around the bend so
it goes into place more fully. But PLEASE be gentle and don't force
it.
Make sure that the Earplug is correctly attached. In rare cases,
the Earplug could remain in your ear after removing the D30
device. If this happens, have the Earplug removed by a healthcare
professional.
If you apply hairspray or cosmetics, please do so BEFORE
inserting the D30 devices. Otherwise they could clog the
microphone. Likewise, if you apply hand lotion, please do so
AFTER the devices have been inserted, so the lotion does not clog
the microphone.
Consult your hearing care professional if you have difficulties
removing the hearing aid.
After removal, it's a good idea to inspect your devices for wax
buildup, or to replace the Earplugs or wax guards if needed. You
can read more about this in the D30 Care section
AMPLIFICATION LEVELS
Your D30 devices have four Volumes, ranging from different
amplification. To go from one volume to the next, switch the knob
for volume controll.
Stop using the Hearing Aid
1) If any of the symptoms described below occurs, stop using the
hearing aid and seek medical assistance or contact your hearing
aid dispenser:
There is a rash or eczema on parts where the hearing aid
contacts the skin.
The skin contacting parts of this hearing aid are made of a
special material designed to minimize skin irritation. However, in
rare cases, allergic reactions may occur, which can lead to
eczema.
There is discharge from the ear during hearing aid use, or
treatment of the ear has become necessary.
Hearing capability has suddenly deteriorated markedly.

VIII. MAINTENANCE AND CLEAN
8.1Daily maintenance
It is KEEPING YOUR D30 DEVICES CLEAN
The Earplugs may sweep out excess wax with each removal.
There's often a sizable amount of wax that may come out
during the initial days of using your
devices. That amount should lessen over
time. Wax buildup orother debris may
lessen their sound quality and perfor-
mance.
• CONTACTS
Wipe the contacts with the microfiber cloth.
• CLEANING THE CRADLE
Lint or wax can also collect on the gold charging contacts
inside the cradle. Periodically check this area to make sure it
is clean. If you see any lint or wax, you can also clean this

area with the microfiber cloth.
Ø DON'T SHARE YOUR D30 •
For hygienic reasons, please
do not do this.
• KEEP D30 DRY
Before placing your D30 devices in the charger, make sure
the devices are completely dry. Long-term exposure to
moisture can harm your devices. Let your devices air dry or dry
them with a dry cloth.
Don't use hot air or a hair dryer to dry your D30 devices. It
might give them that stylish, carefree, wind-blown look, but it
could also damage their internal electronics.
• D30 DEVICES ARE NOT WATERPROOF
Last but certainly not least, D30 devices are not waterproof.
Please do not immerse or submerge your devices in water,
alcohol, or any liquid. Don't wear them while swimming or
showering, and leave them behind when visiting a hot tub or
steam room.

-21- -22-
8.2Cleaning
1)Replace the earplug
On average, the Earplugs will need to be changed every 3
months due to wax buildup. People with a lot of wax may need
to do it more frequently. You'll find out quickly which camp
you're in. Replacement Earplugs can be found in the package.
Grasp the body of the D30 device between your thumb and
index finger.
With your other hand, grasp the Earplug on one side at the
bottom and peel it up and away from the body of the device.
Discard the used Earplug
Now that the Earplugs are removed, use a dry cloth to wipe
the nose clean.
Take the clean Earplug in your other hand. Face the base of
Earplug toward the nose, push and twist it all the way on,
making sure to cover the orange markings on the device.
9.1 Daily maintenance
It is important to keep your instrument clean and dry. On a daily
basis, clean the hearing instruments using a soft cloth or tissue.

XI. TIPS FOR BETTER COMMUNICATION
Your hearing professional will recommend an appropriate
schedule to help you adapt to your new hearing aids. It will take
practice, time and patience for your brain to adapt to the new
sounds that your hearing aids provides. Hearing is only part of
how we share thoughts, ideas and feelings. Reading lips, facial
expressions and gestures can help the learning process and add
to what amplification alone may miss.
Please review the following simple communication tips:
For You
•Move closer to and look at the speaker
•Sit face-to-face in a quiet room
•Try different locations to find the best place to listen
•Minimize distractions
•Background noises may be frustrating at first; remember, you
have not heard them for a while
•Let others know what you need; keep in mind that people
cannot “see” your hearing loss
•Develop realistic expectations of what your hearing aids can
and cannot do
•Better hearing with hearing aids is a learned skill combining
desire, practice and patience
For Your Family and Friends
Your family and friends are also affected by your hearing loss.
Request that they:
•Get your full attention before beginning to speak
•Look at you or sit face-to-face in a quiet room
•Speak clearly and at a normal rate and level; shouting can
actually make understanding more difficult
•Rephrase rather than repeat the same words; different words
may be easier to understand more difficult
•Rephrase rather than repeat the same words; different words
may be easier to understand
•Minimize distractions while speaking
Hearing aids
whistling in the
charger
Incorrect orientation
Turn off the hearing aids.
Reposition your hearing aids in
the port with the earbud resting
in the charger reservoir. Confirm
that the charging LED begins to
glow.
Dead battery
Your charger’s on-board battery
has died. Plug your charger in.
If you do not have the cord with
you, push and hold the hearing
aids’s rocker switch for 3
seconds to turn it off. This will
conserve the charge in your
hearing aids.
