Welcome
Welcome to a world of better hearing!
We understand that hearing loss can have an adverse
effect on quality of life. That is why we are committed
to building hearing aids of the highest quality. Your
new hearing aid will soon become indispensable to
you, and make your life more fulfilled and enjoyable.
Your new GOhear-in hearing aid has been programmed
to match your individual hearing loss profile to help
enhance your hearing and so improve your ability to
understand and follow conversations.
A period of adjustment may be necessary to become
used to your new hearing aid and the restored world of
sound you will experience. The adjustment time varies
for each individual and may last as little as two weeks
or as long as several months. Allow yourself time to
become familiar with sounds you have not heard for a
long time.
Before using your hearing aid, please read this user
guide thoroughly.

Fitting the Correct Tip
Each hearing aid is available with a choice of three tips.
You will notice a tip has already been fitted to your
hearing aid. If, after properly inserting your hearing
aid into your ear, you experience whistling when the
volume is turned up, or it is too loose or tight, you, or
your Sonetik Specialist, can exchange this tip for one
of a different size. Before
removing the tip, please take
note as to how it was fitted,
so that when you replace it
you will know the correct
placement on the nozzle.
NOTE: Once you find the size tip that best suits your
ear, fill in the appropriate section on the hearing test
result sheet that you were given after your hearing
consultation. This will serve as a reminder when it
becomes necessary to re-order replacement tips.

Left and Right Hearing Aids
If you are wearing hearing aids in both ears, it is important
to use the correct device for each ear. The hearing aid
for the right ear has a «red» shell and for the left ear a
«blue» shell.
Turning Your Hearing Aid On
To turn your hearing aid
«on», you simply need to
close the battery door after
inserting a battery.
Turning Your Hearing Aid Off
Apply light pressure on the notch on the battery door,
and swing the door open until the battery is fully visible.
Your hearing aid is now «off».
When the hearing aid is not in use, it is recommended
that you always open the battery door fully. This helps
prevent excessive battery drain and allows proper
ventilation of the hearing aid.

8
Inserting and Removing Your Hearing Aid
This hearing aid should fit comfortably and easily in your
ear. Your Sonetik Specialist will provide instructions on
proper insertion and removal.
To insert a hearing aid, grasp the
removal line between your thumb and
forefinger, so that the sound outlet
of the hearing aid points at you and
the product information printed on
the hearing aid is facing away from
you. Move your hand to the ear canal entrance and
gently push the hearing aid into your ear canal until the
faceplate covers it up. When properly inserted it should
not stick out of the ear canal entrance.
To remove your hearing aid, locate and grasp the removal
line between your thumb and forefinger and slowly pull
the hearing aid from your ear.
CAUTION: In the unlikely event that the tip should
come off and remain in your ear, go immediately to your
physician to have it removed. NEVER insert anything into
your ear in an attempt to remove the tip.
Selecting Your Program
Refer to the hearing test result that you received from
your Sonetik Specialist to find the base program for your

9
right and left GOhear-in hearing aids.
Your GOhear-in hearing aid is equipped with a “no-touch”
program change system.To change the program, tap twice
onto your ear, and you will receive confirmation that the
program has been changed.
There are four different programs (volume levels). With
each set of taps you select a higher program, unless your
hearing aid is already set to program 4. From program 4,
further tapping will bring it back to program 1 again.
If you change to program 1, you will hear 1 beep
If you change to program 2, you will hear 2 beeps
If you change to program 3, you will hear 3 beeps
If you change to program 4, you will hear 4 beeps
Whenever you turn your GOhear-in hearing aid on, it
start at the last program selected and the applicable
beep sequence will be audible after approx. 10 seconds.
You may find that certain programs are more comfortable
in different situations. For instance program 1, which
has less amplification, might be more suitable for noisy
environments such as restaurants. On the other hand,
program 4, which has more amplification, might be more
useful when listening to a speaker in an auditorium.

Battery Information
Battery Size
Your GOhear-in hearing aid uses a standard size A10
hearing aid battery, which is available for purchase from
your Sonetik Specialist.
Low Battery
Your GOhear-in hearing aid is equipped with a low battery
detection system, which continuously monitors battery
life. When the battery level becomes low, a low battery
warning sequence consisting of 3 double beeps is initiated.
When the warning beeps have finished, normal operation
resumes. Battery replacement is recommended when you
hear this low battery warning signal.
The low battery warning sequence will repeat every 10
minutes until the battery becomes critically low. The end of
battery life warning sequence, consisting of 6 double beeps,
is then triggered. The device is then muted and put into low
power sleep mode. At this point it is necessary to replace
the batteries.
The hearing aid battery packaging usually shows a voltage.
This is the idle voltage of the battery (when not in use).
If you measure the voltage with a voltmeter, you will
see the battery voltage in use, which is much lower than
when it is idle. A lower result from the voltmeter does not
limit the performance or service life of the battery in any way.

11
Inserting the Battery
Step 1: Apply light pressure on the notch on the battery
door, and swing the door open. Do not force it. Remove
the battery. If you have difficulties removing the small
battery with your fingers, use a pen nib to push it out of
its compartment.
Step 2: To ensure proper battery
usage, please remove the tag
from the battery and allow the
battery to sit for two minutes
before inserting it into the hearing
aid. Insert the battery carefully with the «+» side up,
facing the side where the product information is printed.
Step 3: Swing the door into the closed position. The
door should close easily. Do not
force it. If there is resistance,
check that the battery has been
inserted correctly.
The life of your hearing aid battery will vary depending
on length of daily use, listening environments, and how
your hearing aid is programmed.When the hearing aid
battery goes dead, remove it immediately and replace
it with a new battery. Batteries may be purchased from
your Sonetik Specialist.

Cleaning Your Hearing Aid
The following instructions will help you to extend the life
of your hearing aid.
To Clean the Exterior of the Hearing Aid:
You should inspect your hearing aid daily and clean it
periodically to control build-up of dust, dirt and wax.
To clean, wipe the surface very gently with a soft, dry
cloth or use only moist cleaning wipes made especially
for hearing aids. Never use water or other liquids when
cleaning the hearing aid.
To Clean the Ear Tip:
Inspect the tip of the ear canal portion of the hearing
aid for any wax build-up. To clean, wipe the tip
very gently with a soft, dry cloth or use only moist
cleaning wipes made especially for hearing aids and
their accessories. The tip should be cleaned regularly
and exchanged at the latest after three months.
Be very careful not to push wax into the ear wax filter.
It is important that the ear tip fits properly into your
ear. Your hearing aid is constructed from the highest
quality materials, and the likelihood of an allergic
reaction is low. If the ear tip irritates your ear in any
way, contact your Sonetik Specialist.

13
To Clean the Microphone Filter:
Use a brush to remove any ear wax from the
microphone filter. Be careful that you don’t push the
ear wax inside the microphone filter. Hold the hearing
faceplate facing downwards ensuring loose wax
falls out and away and not into the filter. If you can’t
remove the ear wax from the microphone filter,
contact your Sonetik Specialist.
To Clean the Ear Wax Filter:
It is important to replace the filter as soon as it has
become clogged, or after one week to maintain
optimal performance.
You can purchase additional filters from your Sonetik
Specialist. There is a tool included in the exchange
filter pack. Use this tool to pick up the clogged filter
and remove it from the hearing aid. Pick up a new
ear wax filter and press it onto the aperture at the
end of the hearing aid. When purchasing exchange
filters, you will receive a separate user guide. If you
have difficulties replacing the ear wax filter, contact
your Sonetik Specialist.

The wearing of an in-the-ear hearing aid may
accelerate the accumulation of ear wax. This can
easily be removed by your physician. Regular annual
visits are recommended. You should not use cotton
swabs to clean your ears, due to the risk of pushing
the wax deeper into the ear canal.
Caring for Your Hearing Aid
The tip may need to be changed if it becomes stiff, brittle,
kinked or damaged. It should always be changed every
three months, at the very least.Your Sonetik Specialist
should change the ear tip. This is to prevent the tip from
detaching from the hearing aid during insertion into the
ear. If your Sonetik Specialist instructs you to change
the tip yourself, make sure it is securely fastened to the
hearing aid before inserting it into your ear.
It is important to replace the ear wax filter as soon as it
has become clogged, or after one week.
Hearing aids are exposed to moisture in the form of humidity
and perspiration while being worn.The daily use of a
dehumidifying kit with a drying capsule is recommended.
Your Sonetik Specialist may carry these accessories for you
to purchase or recommend a place of purchase to you.

15
Extended Storage
If it is necessary to store your hearing aid for an extended
amount of time, follow the steps below for proper storage.
1. Remove the battery.
2. Clean the hearing aid according to the instructions
on page 12.
3. Place the hearing aid in a cool, dry place. It is
recommended that you use either the original
container or a hearing aid dehumidifier.
Telephone Use
Your GOhear-in hearing aid allows you to use the phone
as you would normally do – by holding the phone up to
your ear. Don’t press the telephone receiver too much
onto your ear to avoid unwanted feedback. If feedback
still occurs, a program with less amplification might be
better to use on the phone.
