OVERVIEW
1. 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 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 similar to the human voice.
The combination of starting and stopping sound vibrations and oral
articulation creates comprehensible human speech.

GETTING STARTED
4. Basic use
You must insert the battery into the device in order to turn it
on. Take one of the two, included in the package, batteries
and carefully remove the transparencies. Swivel the bottom
cap of the device. Insert the battery by ensuring that the "+"
and "-" signs of the battery and the device match. Swivel the
bottom cap back.
NOTE: Inserting the battery incorrectly will not damage the
device, but it will not work.
When the Top cap of the device touches the throat skin and
you press the Speech Button, the device starts to emit sound.
This allows the proper function of the product.
5. Finding the sweet spot
A sweet spot is a place where you feel the sound from the electrolarynx
transmits through your neck tissue and your oral cavity with the most
clarity. The easiest way to find your sweet spot is to place the electrolarynx
on your neck in different positions and actuate the sound while you are
pushing the START button. What you are looking for is the place on your
neck, which transmits sound the best. While looking for a sweet spot, it is
crucial that you press it firmly against your neck tissue, so the sound
transmits through your tissue and out your oral cavity. Take your time
finding your sweet spot –this is the most crucial part of learning to use an
electrolarynx. Finding just the right place will set you up for success.
6. First Words
After you have pinpointed the desired spot, you can start making some
basic sounds. Focus on single vowels first. Over-articulate every sound with
your mouth until you feel comfortable with all the vowels. After that, you
can start practicing short words. Slowly work your way up to sentences and
conversation.

7. Expectations
Sometimes learning to speak with an electrolarynx device is not easy. Think
of it as learning to play a musical instrument. It will take time, practice, and
patience.
In some cases, talking can be achieved in a month, in other cases it can
take only 3 days.
