OVERVIEW
What is Labex Comfort
Labex Comfort is a digital electrolarynx device. It
is specially designed to help laryngectomees talk.
Its main feature is the two individually
configurable talk buttons.
Labex Comfort is a CLASS I medical device.
General principle of operation for all models
electrolarynges manufactured by Labex Trade
Ltd.:
The digital electrolarynx produces mechanical
vibrations with a low sound frequency between
60-195 Hz. Applied to the neck, these vibrations
create trembling in the oral cavity compensating
for the energy generated from the lungs.
The combination of starting and stopping sound
vibrations and oral articulation creates
comprehensible speech.

GETTING STARTED
Basic use
You need to insert the battery into
the device to turn it on. Take one
battery of the two included in the
package, and carefully remove the
transparencies. Unscrew the Battery
Cover of the device. Insert the
battery minding the polarity. Make
sure that the "+" and "-" signs of the
battery and the device match. Swivel
the Battery Cover back to the device.
NOTE: Inserting the battery
incorrectly will not damage the
device, but it will not work.
Press the Top Cap of the device firmly against the
neck and then hold Talk Button 1 or Talk Button 2
to speak. The device will start to emit sound. This
allows the proper function of the product.

Finding the sweet spot
A sweet spot is called a place on the throat area
where you feel the sound from the electrolarynx
transmits through the neck tissue and out of the
oral cavity with the most clarity.
The easiest way to find your sweet spot is by
tightly pressing the electrolarynx Top Cap in
different locations on your neck area and
articulating a single vowel while pressing one of
the Talk Buttons.
What you are looking for is the place on your
neck, which best transmits the sound. While
looking for a sweet spot, it is crucial that you
press the device tightly against your neck tissue
so the sound transmits through the tissue and
out of the oral cavity. Take your time finding your
sweet spot –this is the most important part of
learning to use an electrolarynx. Finding just the
right place will set you up for success.

Labex Comfort User Manual, Date: 15 February 2021, # 8
First Words
After you have pinpointed the desired spot, you
can start making some basic sounds. It is crucial
to over-articulate every sound with your mouth
until you feel comfortable. After that, you can
start practicing short words. Slowly work your
way up to sentences and conversation.
In some cases, talking can be achieved in a
month, in other cases, it can take only 3 days.

BATTERY
Low battery
Labex Comfort has a built-in battery indicator,
which will warn you when the battery level is low.
When the battery charge goes down to 20%, the
Battery Indicator will start blinking after every
release of a speech button. When the battery
drains down to 10%, the Battery Indicator will
light up in solid red. At this point, you should
recharge your battery, or replace it with a fully
charged one.
Different batteries
There are two high-capacity Li-Ion batteries
included with your Labex Comfort. This will allow
you to always have a fully charged battery on
hand. However, Labex Comfort is compatible with
all 9V batteries on the market –rechargeable or
non-rechargeable.

Labex Comfort User Manual, Date: 15 February 2021, # 13
Charging the battery
After you remove your drained battery, you
should charge it with the included intelligent
charger:
1) Put the battery inside the charger, minding
the polarity, i.e. the “+” and the “–“.
2) Put the charger into an electrical socket.
3) The corresponding red LED will light up,
meaning the battery is currently charging.
4) The red LED will turn off when the battery is
fully charged.
NOTE: The included intelligent charger will NEVER
overcharge your batteries.
WARNING: Do not try to charge ANY other kind of
battery with the charger! The charger is designed
ONLY for Lithium-Ion batteries! Trying to charge
any other kind of battery will result in permanent
damage to the battery and the charger!
NOTE:If you find that the battery can not hold a
charge for more than one hour of use with your
device, it may be near the end of its life cycle. If

Labex Comfort User Manual, Date: 15 February 2021, # 14
this happens, we advise you to recycle this
battery and get a new one.
NOTE: If the battery temperature is over 45 ℃
the charging process will be temporarily stopped
until the battery cools below 45℃. This protects
the battery. If the charger or the battery is
exposed to direct sunlight, move it to a cooler
place. The charging will continue after the battery
cools down.
