7. Retention wire Used to ensure your hearing aid remains in place.
Before you can begin using your Lexie hearing aids, you will be
required to select the correct slim tube length and dome size for your
specific ear. This is an important process that will allow you to get
comfortable with the fit and feel of your hearing aid.
In order to select the correct slim tube length, it is important to
first measure the size of your ear by using the ear measuring tool
provided. This measuring tool will allow you to determine which
slim tube would be the most comfortable fit for your ear. Slim tubes
are available in four different lengths namely, size 0, 1, 2 and 3, with
size 0 being the shortest in length and size 3 being the longest. The
ear measuring tool will indicate which slim tube length will be the
best fit for your ear. Follow the steps below in order to complete this
process:
The ear measuring tool has two
colors, namely red and blue. Begin
by placing the measuring tool over
your ear as illustrated. The red side
must be showing when it is over
your right ear and the blue side
must be showing when it is over
your left ear.

Take a photo of your ear so
that you can clearly see the
measuring tool on your ear.
You may need to ask a family
member or friend to assist
you with this step, if you
experience any difficulties.
At the bottom of each slim tube, you will find a number in either
blue or red. Just as with the ear measuring tool, a slim tube with
a red number on it, will indicate that the slim tube is intended
for the right ear and a slim tube with a blue number on it, will
indicate that the slim tube is intended for the left ear.
Once you have determined the correct slim tube length for your
ear, find the slim tube with the correct number and color that is
needed for your hearing aid.
Select the correct slim tube recommended by the ear measuring
tool. If you have two hearing aids, repeat this process for your
opposite ear.
On your ear measuring tool, locate
the closest number that is most
parallel to the top of the opening of
your ear canal. This number will be
needed in order to select the correct
slim tube length.

Removing and attaching your slim tube to
your hearing aid
Each Lexie hearing aid comes with a standard size ‘2B’ slim tube
attached to it. Should you need to replace this slim tube, follow the
steps below:
In order to remove the slim tube, hold the slim tube firmly in
one hand at the attachment between the slim tube and hearing
aid and use your opposite hand to gently unscrew the slim tube
approximately 90 degrees in an anticlockwise direction and pull
to remove the slim tube from your hearing aid.
Take the correct sized slim tube and gently push it onto your
hearing aid until it snaps into position.
Note:
Make sure to grip the slim
tube attachment and not
the tube itself.

Selecting the correct dome size
Each Lexie hearing aid comes with three different types of domes,
namely; open domes, double domes and tulip domes. Lexie hearing
aid domes are made out of a soft rubber material and attach to
the end of the slim tube. Open domes come in three sizes - small,
medium and large. Double domes come in two sizes - medium and
large.
Your Lexie hearing aid comes pre-assembled with a tulip dome,
which has one standard size. This dome should be used to complete
the Lexie Hearing Check, as its flexibility allows it to fit into many
differently sized ear canals.
Once you have completed the hearing check and your hearing aid
has been set to your unique hearing profile, you may try different
dome types and sizes, if necessary. Try the different sizes of that
dome type to find the most comfortable fit for your ear canal. The
dome should fit snugly in the ear canal opening, so that the ear canal
is properly sealed. In other words, the dome shouldn’t feel like it is
falling out of the ear or that it has to be squeezed or forced into
the ear.

If it feels like the dome is falling out of your ear, it means that
the dome is most likely too small for your ear. Try changing
your dome to one that is a size larger.
It is useful to know when to use a closed or open dome.
If it feels like you have to squeeze or force the dome into your ear,
it means that the dome is most likely too large for your ear. Try
changing your dome to one that is a size smaller.

Closed dome
Closed domes do not have holes in
them and are used when the hearing
aid seems too quiet. Closed domes
can also help to prevent your hearing
aid from whistling at higher volume
levels.
Removing and attaching your dome to the
slim tube
Follow the steps below in order to remove and attach a dome to your
slim tube when necessary.

Take the new dome and push it firmly onto the tip of the slim
tube as illustrated. Ensure that the dome is placed correctly
onto the slim tube. You should be able to tug it slightly without
removing it.
3.
Note:
In the unlikely case that any parts remain in the ear canal
after the removal of your hearing aid, seek medical attention
immediately.
It is important to identify your right hearing aid from your left
hearing aid before positioning your hearing aid on your ear. The slim
tube that is attached to your hearing aid will have a red or a blue
number on it. If the number on your slim tube is red, it indicates that
it is the right hearing aid. If the number on your slim tube is blue, it
indicates that it is the left hearing aid.
A useful way to remember this is: Red is Right; Blue is Left.

Positioning your hearing aid on your ear
It is simple to position your hearing aid on your ear, but it can take
some practice.
Begin by placing the hearing aid body behind your ear.
Hold the slim tube between your thumb and forefinger, at the
bend closest to the dome. The dome should face towards the
entrance of the ear canal (this is the cavity that runs all the way to
your eardrum).
Gently press the dome into your ear canal until the slim tube sits
comfortably against the side of your head.

Note:
If the retention wire on your slim tube is too long, you may cut the length
slightly. Be careful not to shorten the length too much, as this could affect
how well the hearing aid remains in your ear.
Tip:
The dome should be completely, or
almost completely, in the ear canal.
The ear tip cannot touch the eardrum.
Proper insertion of the dome is key to
getting enough loudness and to avoiding
whistling. If you wear eyeglasses, first
position your hearing aid on your ear
before you put your glasses on.
You can use a mirror to ensure that your hearing aid is positioned
correctly onto your ear.

Using your hearing aid
Batteries
Inserting the battery
Your hearing aid uses a standard size 312 zinc-air
battery. Each battery lasts approximately 5-8
days depending on hearing aid usage.
If the battery lasts less than 5 days please visit
our troubleshooting section on the website in
order to determine the possible cause of this
shortened battery life.
Only use batteries with maximum 1.5 volt.
Please do not use silver-zinc or lithium-ion
rechargeable batteries; these could severely
damage the hearing aids.
The battery door is found at the bottom of your hearing aid. To
insert a battery, gently pull on the tab found on the battery door
until it opens. Do not use excessive force.
1.

Removing the battery
Open the battery door gently.
Use the magnet at the head of your cleaning brush to lift the
battery out of the hearing aid battery drawer.

19
Insert the battery into the battery door,
whilst ensuring that the ‘+’ side faces up.
Do not force the battery into the battery
drawer. If the battery does not want to go
into the battery drawer or the battery door
does not want to close, it is most likely
that the battery is facing the wrong way.
Once the battery door is closed, you
will hear a voice prompt indicating the
default listening environment that
your hearing aid is currently set to e.g.
‘Program 1’. Thereafter, your hearing
aid will start working. Hold the hearing
aid close to your ear in order to hear this
voice prompt.

Remove the sticker found on the positive
side of your 312 battery. Only remove this
sticker once you are ready to use the
battery. Zinc-air batteries are activated
by air. For best results, wait 2-3 minutes
before inserting the battery, in order to
give it a chance to activate.

Note:
Although your hearing aids will now be switched on for the first time, they
will still need to be optimized according to your hearing check results and
therefore, at this stage, your hearing aids will not be providing optimal
benefit. You will need the Lexie App in order to optimize your hearing aids.

Note:
When your hearing aid is not in use, open the battery door and remove the
battery in order to preserve the life of the battery. Battery life can also be
monitored in the Lexie App.
How will I know when to change the battery?
Low battery- You will hear a ‘Low battery’ voice prompt, every 8
minutes to indicate that your hearing aid battery is low and needs to
be replaced.
Replace battery- If you do not replace your battery after the low
battery warning, you will hear a ‘Replace battery’ voice prompt just
before your hearing aid automatically turns off.

are similar in size and shape.
Ensure that loose batteries do not lie around in bulk as this may
cause cell shorting and heat build-up.
Do not puncture or abuse batteries.
Dispose of batteries in an environmentally friendly way in
accordance with Federal and State requirements.
Zinc air batteries may release small amounts of zinc oxide to the
environment if abused and disposed of improperly.
Ingestion of a battery can be harmful, never swallow. If ingested
seek immediate medical attention or call the NATIONAL
BATTERY INGESTION HOTLINE any time on [phone].
Switching your hearing aid on and off
Your hearing aid will automatically switch on once a battery has
been inserted and the battery door has been closed.
In order to turn your hearing aid off, open the battery door, at
least halfway. Be sure to open the battery door when you are not
wearing your hearing aid in order to preserve the battery life and
allow internal moisture to evaporate.

Telecoils
Your hearing aid has a telecoil that converts electromagnetic signals
directly from the telephone into sound. To use the telecoil, select the
appropriate environment setting, using the listening environment
control button on your hearing aid or the Lexie App. The telecoil
setting may allow you to hear more clearly on the telephone. After
finishing your phone call, change back to your preferred listening
environment.
If your phone is labeled “Hearing Device Compatible,” it will work
with a telecoil.
Other uses of a telecoil
Many people use the telecoil with assistive listening devices called
induction loops. If you go to a public event, and the room is “looped,”
then you can use your telecoil. Set your hearing device to the telecoil

The serial number (S/N) is located on the hearing device as an
8-digit number. The first two digits of the S/N represent the year of
manufacture (i.e. “20” refers to 2020). The last six digits are a unique
identifier. All eight numbers create the serial number of the device.

Note:
If you have two Lexie hearing aids, clean one hearing aid at a time.
This will ensure that your left and right hearing aids do not accidently
get switched around.
Hearing aid
maintenance and care
Cleaning
Dome
33
If well cared for, your Lexie hearing aid will last for many years. Your
hearing aid should be cleaned daily in order to ensure optimal
functioning and to prolong the lifespan of your hearing aid.
The dome of your hearing aid needs
to be kept free of earwax at all times.
Earwax will prevent the amplified sound
from entering your ear. Therefore, it is
important to clean your dome daily.
Use a soft tissue or the cleaning
brush provided to clean the dome of
your hearing aid.
1.

34
Note:
Even if your domes are well cared for, they will need to be replaced every
2-3 months due to general wear and tear.
Slim tube
Wax, dirt or condensation can block your slim tube and prevent
sound from going through. Therefore, your slim tube must be
cleaned weekly. If a blockage is noted, follow the steps below to
remove the blockage.
35
Do not submerge or rinse your slim tube
in water, as there is a risk that water may
become lodged in the slim tube. If water
does get into your slim tube, blow through
the tube and make sure that it has dried
properly before you reattach it onto your
hearing aid.
Reattach your slim tube to your hearing aid. Make sure that the
angle is correct after you have connected your slim tube to your
hearing aid.
Use a soft dry cloth or tissue to gently wipe down the body
of your hearing aid. This is an electronic device. Don’t use any
liquids (water, solvents or cleaning agents) on the body of your
hearing aid. Should you do so, your hearing aids will break.
4.
5.
1.
Note:
After 4 to 6 months of regular use, your slim tube will start to harden and
might turn yellow. This will affect the sound quality of your hearing aid.
When this occurs, it is time to replace your slim tube.
Hearing aid body
Remove the slim tube from your hearing aid.
Use a damp cloth to clean the outside of your slim tube.
Thread the cleaning wire provided
all the way through your slim tube
to remove any earwax or foreign
particles. The cleaning wire should
be inserted at the point where
your slim tube attaches to your
hearing aid and must be pushed
all the way through the slim tube
and out through the dome.
1.
2.
3.

36
Note:
Make sure to handle your hearing aid over a soft surface during the cleaning
process in order to prevent damage to the hearing aid, should you drop it.
Caution:
If you do not follow the list below you may damage your hearing
device and accessories during cleaning.
Do not immerse your hearing device in water or liquid, even
when cleaning.
Follow the recommended cleaning guidelines to clean your
hearing aid.
Do not bend the slim tube and dome back and forth to
remove it.
Do not use the cleaning wire while the slim tube is connected to
the hearing device.
Do not use alcohol to clean your dome.
Do not use sharp tools to dislodge ear wax.
If your physician prescribes ear drops, clean any moisture that
may get into the slim tube.
37
Storing your hearing aid
What is a drying capsule?
How do I use a drying capsule?
Drying capsules are used to prolong the lifespan
of your hearing aid by drawing moisture from it.
Two drying capsules are supplied in your Lexie
hearing aid box.
Find an airtight container that can hold your hearing aid and
one drying capsule. Ensure that the container you choose fits
your hearing aid comfortably but that it is not too large. A smaller
container will prolong the lifespan of the drying capsule.
When ready to use, remove the drying capsule from its
packaging. DO NOT remove the white paper seal from the back
of the drying capsule.
Open the airtight container and place the drying capsule inside
this container with the white paper seal of the drying capsule
facing upwards.
