The Mouthpiece is made of a softer material than the rest of the Airofit PRO 2.0 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 immerse the E-Unit, or expose it to jets of water, or any other liquids.
To clean or charge your Airofit PRO 2.0 Breathing Trainer, firmly squeeze the grips and remove the E-Unit from the rest of the Trainer.

| Trainer Unit
The term ‘Trainer Unit’ is used for your Airofit PRO 2.0 Breathing Trainer once the E-Unit and Mouthpiece are removed.
| Charging
The charging port can be found on the inside of the E-Unit. Attach the magnetic cable to charge. When the light is blinking green, the cable is attached correctly, and your E-Unit is charging.
When fully charged, the light will show as solid green

Using the Airofit Correctly
When using the Airofit PRO 2.0 Breathing Trainer, you should be relaxed and sitting upright. Keep your head facing straight forward, as looking down can cause more salivation. Do not hold the Airofit PRO 2.0 Breathing Trainer with your hand during training unless absolutely necessary. If you must, hold it with your hand on the E-Unit and make sure that 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. The Mouthpiece bite block should be gripped between your teeth.

When starting the exercise, the Breathing Trainer requires a short calibration (zeroing) of the pressure measurement. Do not breathe into the Trainer during this process. Wait for the instructions to begin the respiration exercise.
Airofit PRO 2.0 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.

Maintenance

• Always make sure that your device is dry before storing it. We advise you to store your Airofit PRO 2.0 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 Airofit PRO 2.0 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 before cleaning the device. Do not immerse the E-Unit, or expose it to jets of water, or any other liquids. We recommend washing the Trainer Unit and the Mouthpiece in warm water (below 60°C). After washing, shake off and blow through the Trainer Unit to remove excess water, making sure it’s completely dry before reassembling. The Airofit PRO 2.0 Breathing Trainer is not autoclave or dishwasher safe.

• Weekly Maintenance
  Once a week, 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 off excess water, blow through the Trainer Unit, and dry with a clean towel. Let it air dry. Make sure the device is completely dry before reassembling.

• Monthly Maintenance
  Charge your Airofit PRO 2.0 Breathing Trainer fully at least once a month, even when not in use, to avoid complete battery depletion.

6 Getting Started with Airofit PRO 2.0

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 Trainer Unit and Mouthpiece in warm water, wipe them with a clean towel, and let them air dry. When the E-Unit is fully charged and the Trainer Unit and Mouthpiece are completely dry, you can reassemble the Breathing Trainer. The E-Unit contains electronics; do not immerse the E-Unit, or expose it to jets of water, or any other liquids.

Sign-up procedure
The Airofit app will guide you through the initial steps of your Airofit journey.

Lung Test
As instructed in the Airofit app, you will initially perform a lung test to establish your breathing condition. The app notification will pop up when you should take the lung test.
The lung test records your

• Accessible Lung Capacity, your active lung volume
• Inhale strength, your Maximal Inspiratory Pressure (MIP)
• Exhale strength, your Maximal Expiratory Pressure (MEP)

These measures are evaluated based on your gender, age, and height (as set in your profile). The percentages (0-200%) show how you compare to other users in the same demographic group as you.

Start Training
Based on the goal selected in the Airofit app, you will find 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 finished, 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.

Training History
The app contains your training history so that you can access your lung test and training session results at any time.

Settings
You can update your profile 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/off 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 find 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.
