3Safety Precautions
3.1 Health Considerations when Using Airot PRO
To prevent damage to your Airot PRO or injury to yourself, read the following
precautions in their entirety before using the Airot system.

2
• To prevent the potential transmission of infections, we recommend that you
do not share your Airot PRO with any other user, including family members.
Moreover, your Airot PRO is calibrated for only one user’s personalized data.

should only use Airot under the supervision of an adult.
• Immediately stop the exercise if you feel any physical discomfort.
• If you feel light-headed or dizzy while exercising with Airot, you should stop
and check the resistance wheel's inspiratory and expiratory settings.
• If you are suering from a cold, sinusitis, or other respiratory tract infection,
we advise you to wait until all symptoms have disappeared before using the
Airot PRO.
• If you have any medical conditions with your respiratory system, heart, or blood
pressure, we recommend that you consult a doctor before using Airot PRO.
• Do not use Airot to inhale any type of substance.

3
3.2 Contraindications
To prevent damage to your Airot PRO or injury to yourself, read the following
precautions in their entirety before using the Airot system.
Use appropriate caution in the following situations:
• A history of spontaneous pneumothorax (collapsed lung), i.e., not due to
traumatic injury.
• A traumatic pneumothorax that has not fully healed.
• A burst eardrum that has not healed fully, or other conditions of the eardrum.
• The subgroup of asthma patients with unstable asthma with abnormally low
perception of dyspnea (shortness of breath) are also unsuitable candidates
for Inspiratory Muscle Training (IMT).
3.3 General Safety Cautions
• Only use the Airot PRO Breathing Trainer together with the Airot mobile
application and the selected sessions and programs. Always set resistance to
the recommended settings.
• Do not drop your Airot PRO. Dropping the trainer may result in malfunction
or cause a decline in performance.
• Ensure that the inhale/exhale vents located on the sides of Airot PRO are not
obstructed while training.
• Do not expose the E-Unit to any liquids. For cleaning instructions, refer to the
Maintenance section.
• Never use scouring pads, abrasive cleaning agents, or aggressive liquids such
as petrol or acetone to clean the device. The Airot PRO is not dishwasher or
autoclave safe. For cleaning instructions, refer to the Maintenance section.

4
• Ensure that your Airot PRO remains hygienic and in good working order.
Always make sure that your device is dry before storing it. We advise you to
store your Airot PRO in a suitable, clean, and hygienic way.
• Only use the supplied micro USB cable or another CE-certied USB cable,
together with a CE-certied USB charger (refer to Technical Specications).
• If you have more than one Airot PRO Breathing Trainer, do not swap the
E-Units. Each E-Unit is calibrated precisely to the device, and swapping them
will cause inconsistencies in measurement results.

Power Button
Press the Power button to turn ON the Airot PRO Breathing Trainer.
It will begin to blink green to indicate that the device is ON - at this
point, it is ready to be paired with the mobile application.
To turn the device OFF, press and hold the Power button for 3
seconds.
The Mouthpiece
The Mouthpiece is made of a softer material than the rest of the
Airot PRO Breathing Trainer to ensure complete comfort during
exercise.
To use it, gently bend the sides of the Mouthpiece and put it in your
mouth.
Removable E-Unit
The E-Unit contains electronic components. Do not expose it to any
liquids.
To clean or charge your Airot PRO Breathing Trainer, gently squeeze
the grips and remove the E-Unit from the rest of the Trainer.
Trainer Unit
The term ‘Trainer Unit’ is used for your Airot PRO Breathing Trainer
once the E-Unit and Mouthpiece are removed.
Charging
The charging port can be found on the inside of the E-Unit. Insert the
Micro USB cable to charge. If the light is blinking green, the cable is
inserted correctly, and your E-Unit is charging.
When fully charged, the light will show as solid green

4.3 Using the Airot Correctly
When using the Airot Pro you should be relaxed and sitting upright. Hold the
device with your hand on the E-Unit. Make sure the openings near the resistance
wheels are not obstructed.
Place the device in your mouth so that your lips cover the outer shield of
the Mouthpiece and make a complete seal. If you are using the advanced
Mouthpiece, the bite blocks should be gripped between your teeth. Keep your
head facing straight forward, as looking down can cause more salivation. Do not
hold the Airot PRO Breathing Trainer with your hands during training unless
absolutely necessary.
When starting the exercise, the Airot PRO requires a short oset (zeroing) of the
pressure measurement. Do not breathe into the trainer during this process. Wait
for the instructions to begin the respiration exercise.
Airot PRO Breathing Trainer should not be used in conjunction with other
physical activities. Breathing training while performing other physical exercises
will compromise the oxygenation of the locomotor muscles.
4.4 Mouthpieces
Airot PRO comes with an extra mouthpiece. Try each mouthpiece to see which
one ts best.

5Maintenance
Always make sure that your device is dry before storing it. We advise you to store
your Airot PRO Breathing Trainer in a suitable, clean, and hygienic way. Fully
charge your device if you are storing it for more than a week without use to avoid
full battery depletion. Remember to charge the Airot PRO Breathing Trainer fully
before resuming usage.

Daily Maintenance
As the device will be exposed to saliva during use, it is important to clean it
frequently. We recommend cleaning your device after each training session.
Always remove the E-Unit and wipe it with a dry clean cloth. Do not clean the
E-Unit with liquids of any kind.
We recommend washing the Trainer Unit and the Mouthpiece in warm water
(below 60°C). After washing, shake o and blow through the device to remove
excess water, making sure it’s completely dry before reassembling. Airot is not
autoclave or dishwasher safe.
Weekly Maintenance
Once a week, remove both the E-Unit and the Mouthpiece from the Airot PRO
Breathing Trainer to be able to clean it better. Use a drop of dish soap in water
to wash your Trainer Unit and Mouthpiece thoroughly. Once washed, hold the
Trainer Unit under running water, allowing it to run through. Shake o excess
water, blow through the device, and dry with a clean towel. Let it air dry. Make
sure the device is completely dry before reassembling.

9
Monthly Maintenance
Charge your Airot PRO Breathing Trainer fully at least
once a month, even when not in use, to avoid complete battery depletion.
6 Getting Started with Airot PRO
First-time use essentials
Before you start your training, it is recommended to charge the E-Unit until the
light is solid green. While the E-Unit is charging, rinse the rest of the trainer in
warm water. The E-Unit contains electronics; do not expose it to any liquids.
Sign-up procedure
The Airot app will guide you through the initial steps of your Airot journey.
6.1 Lung Test
As instructed in the Airot app, you will initially perform a lung test to establish
your breathing condition. The app notication will pop up when you should take
the lung test.
The lung test records your
• Accessible Vital Lung Capacity , your active lung volume
• Inhale strength, your Maximal Inspiratory Pressure (MIP)
• Exhale strength, your Maximal Expiratory Pressure (MEP)

10
These measures are evaluated based on your gender, age, and height (as set in
your prole). The percentages (0-200%) show how you compare to other users
in the same demographic group as you.
6.2 Start Training
Based on the goal selected in the Airot app, you will nd training
recommendations within the app. Prepare your trainer by setting the correct
resistance levels and follow the app guidance to start the training. When your
exercise is nished, the result screen will appear in the app, and you will see a
summary of your training.
Understanding training levels
• Beginner: Low pressure loads with short breathing cycles
• Intermediate: Medium pressure loads with medium breathing cycles
• Expert: High pressure loads with long breathing cycles
Understanding training duration
Training duration can vary between 1-10 minutes. We strongly recommend that
you always take a short break after every 3 minutes of training.
6.3 Training History
The app contains your training history so that you can access your lung test and
training session results at any time.

11
6.4 Settings
You can update your prole in the settings. Your account is protected by a
password, which can be reset. Preferences for background music and guidance
sound can be turned on/o for your training exercise. If you have any questions
about training, you can get them answered by clicking on the FAQ button. You
can also report a problem if you nd something wrong with the app. The app
also contains the Terms and Conditions (requires internet connection) and the
Privacy Policy, which you agreed to when you created your account.
