1 Device Description
The process that takes place within the NanoVi™ device occurs in five steps:
1 Creation of a continuous air stream with intake of ambient air.
2 Humidification of the air stream, enriching the air stream with water molecules.
3 Generation of a specific electromagnetic energies/wavelengths/signals that are highly absorbable by water molecules.
4 While absorbing the specific electromagnetic energy, the water molecules in the airstream are transformed into a coherent phase that,
when a volume of water is connected to it, leads to the formation of layers of ordered water (EZ-Water) on its surfaces. This coherent
phase is required for layers of ordered water to form. For example, water droplets in the air, proteins within a cell or any other surface
that is in the water when the coherent phase transfers through it.
5 The user is connected to the coherent phase that the water molecules form in the humidified airstream via the Flex-Arm or a Nasal
Cannula attached to the Flex-Arm.
The NanoVi™ device is designed to assist the body’s natural process of creating ordered water layers (EZ Water) on proteins. During a
natural and ongoing process in the body, an electromagnetic signal is emitted by certain free radicals also known as Reactive Oxygen
Species (ROS) and is released into the cellular water causing the formation of the coherent phase. When it reaches the surface of proteins, it
forms ordered water layers (EZ water) on the proteins. NanoVi™ devices generate the same ROS-typical signal and additional, even more
highly absorbable electromagnetic signals. The bio-identical and the far more potent electromagnetic signals are emitted to water molecules
in a humidified air stream, transforming them into the coherent phase that is transferred across the humid air stream to the user.

2 Contraindications
Do not use NanoVi™ when the USER is using other breathing related therapy or remedies.
Pregnant women should consult their physician before using the device.
USERS must be awake and alert when using the NanoVi™. Do not use the NanoVi™ when unconscious or when under the influence of
drugs or medications which interfere with alertness.
3 Possible Side Effects
The following temporary reactions have been occasionally observed when first using the NanoVi™ device. Typically, when side effects occur
the body is going through an adjustment. Try shorter sessions if necessary.
•Drowsiness: Use a shorter session length for the first few sessions, Choose the time of the first session to accommodate unex-
pected drowsiness, which might occur after the initial application. This will disappear after several sessions.
•Insomnia: To avoid trouble falling asleep, do your session at least 4 hours before going to bed when you first start using the
device.
•Dizziness and/or headaches: Dizziness and/or headaches can temporarily appear and should disappear after a short period of
time. Should this occur, use shorter session times.
•Changes in stool: If unwanted changes in stool consistency appear, use shorter session times.
•Skin reactions: If skin reactions, such as reddening and itching, appear use shorter session times until skin reactions have disap-
peared.

6 Operating Instructions
6.1 General Use
The process that takes place within the NanoVi™ device occurs in five steps:
1 Creation of a continuous air stream with intake of ambient air.
2 Humidification of the air stream, enriching the air stream with water molecules.
3 Generation of a specific electromagnetic energies/wavelengths/signals that are highly absorbable by water molecules.
4 While absorbing the specific electromagnetic energy, the water molecules in the airstream are transformed into a coherent phase that,
when a volume of water is connected to it, leads to the formation of layers of ordered water (EZ-Water) on its surfaces. This coherent
phase is required for layers of ordered water to form. For example, water droplets in the air, proteins within a cell or any other surface
that is in the water when the coherent phase transfers through it.
5 The user is connected to the coherent phase that the water molecules form in the humidified airstream via the Flex-Arm or a Nasal
Cannula attached to the Flex-Arm.
The NanoVi™ device is intended to be used on a flat surface. The device may be moved on a cart with the humidifier installed but should
never be carried with the humidifier installed because it could fall off and do damage. The USER can be sitting or lying down. The Flex-Arm
bends following its natural curvature and should be positioned for comfort. The device can be used with or without a nasal cannula. When
used with a nasal cannula, the USER should be positioned close enough to the device that there is never tension (pulling) on the nasal can-
nula. The nasal cannula should be worn correctly (see Section 6.3) as show in Figure 6.1. See Appendix A for proper nasal cannula use. If
the USER is using the device with no cannula, the Paper Tube should be positioned 1-3 inches (2.5 -7.6 cm) away from the nose as show in
in Figure 6.2. The nasal cannula includes a quick disconnect feature which allows for easy connection and disconnection from the system.

Figure 6.6: Optional nasal
cannula use
6.2 Use of Flex-Arm
NanoVi™devices come with an installed Flex-Arm, as shown in Figure 6.3.
Place one of the disposable paper tubes that come with the device onto the end of the arm and push it on to fit snuggly.
Gently pull the Flex-Arm towards your face. The end of the paper tube should be in front of your nose, one to three inches away, as shown in
Figure 6.4. The Flex-Arm can be moved and repositioned for comfort but must not be bent sharply. It is important to be sitting or lying still
and to have the Flex-Arm correctly positioned so that you are inhaling the output from the device.
Do not try to bend the Flex-Arm into sharp angles.
Do not move or attempt to lift the device by pulling on the Flex-Arm.
6.3 Nasal Cannula –Optional Non-Mandatory
The NanoVi™device can be used with an optional nasal cannula inserted on the outlet in the middle of the Flex-Arm. For proper use of the
nasal cannula, refer to Appendix A: Accompanying Documents, User Manual for Nasal Cannulas. The NanoVi™ device should only be used
with the nasal cannula that has the make and model: Nasal Cannula (Adult) Salter Style 1600-1. For proper operation, a short cannula that
has one-foot length tubing is used. The one-foot disposable cannula is shown in Figure 6.5. The user does not have to be still when using
the cannula. It allows the user to make small movements and turn their head without interrupting their session. Use of the cannula is shown
in Figure 6.6.

6.4 Power On
Press the large button on the front panel of the device to turn the power on. The power button will illuminate with a green circle and the touch
screen display will automatically start with a self-test. Once the device is ready, the screen will display standard user options. Pressing the
power button at the end of a session will turn the device off. If you do not turn the device off and it is not used for 15 minutes, it will turn itself
off.
6.5 Touch Screen Interface
The touch screen is operated by lightly touching it with a finger. If necessary, a soft blunt object could be used to operate the touch screen.
Hard or sharp objects should never be used.
A tone sounds each time you press a button, indicating that your input was registered through the touch screen.
The use of hard or sharp objects to operate the touch screen could result in damage to the device.
6.6 Application Schedule
The session time depends on which NanoVi™ device is used. The NanoVi Exo™device is twice as powerful as the NanoVi Pro™, and the
NanoVi Pro device is twice as powerful as the NanoVi Eco™. As a result, the standard session time of 15 minutes on the Exo is similar to 30
minutes on the Pro, or 60 minutes on the Eco device.
It may be necessary to build up use of the device slowly. The appropriate amount of time depends on the state of each person’s health and
physical condition. Although adverse reactions are experienced by only a small percentage of people, a safe approach is to start by using
the NanoVi Eco™ device for only 10 minutes the first day (5 minutes for the NanoVi Pro™ or just a few minutes on the NanoVi Exo™). If you
feel well and are not light-headed, it is fine to do more time. Feeling light-headed or uncomfortable in any way signifies that the session
should be stopped for the day and time should be added gradually. If adverse reactions occur, revert to shorter session times.
It is important to start slowly to stay within your comfort zone. If you are highly sensitive and/or in need of detoxification, start with only a few
minutes and keep adding time each day, as long as there are no adverse reactions. In the event of an adverse reaction, reduce the number
of minutes of use until there is no reaction, then start adding minutes until the desired session time is reached.
For prevention in younger healthy people, two or three standard NanoVi™ sessions per week are adequate. Individuals that have health
challenges, are older, or are performance athletes should use the device more. NanoVi™ devices can be used every day and several times
a day, if desired. There is no potential to be harmed by the device so overuse is not a concern, once you are accustomed to it. The device
can be used for many hours a day if desired.
6.7 Lights Illuminating the Glass Container
This lighting has no bearing on the USER’S treatment and can be set to any preference as needed.
The lights illuminating the glass container are adjusted in the color selection screen. This screen is accessed by touching the color wheel
icon of the splash screen, during the 10-second self-test (Figure 6.8). The color wheel does not show once the self-test is complete, so it is
necessary to restart the NanoVi™ device if you want to adjust the color.
The default light setting is blue. This can be changed to a different color or to a transition of colors. The device keeps running while you are
in the color selection screen so you can see the effect of any changes before leaving the screen. Figure 6.9 shows the color options
available. Touch the circle to select a color. Pressing the white circle eliminates the color but leaves the water illuminated. The brightness
level is adjusted by pressing the sun or moon symbols. To turn the lights off, press the moon symbol until the illumination disappears. The
orange bar will be all the way to the left.
The rotating color option is selected by pressing the symbols for the long or short wavelength. Pressing any part of the color transition bar
will start the rotating colors. Pressing any individual color circle will stop the colors from changing.

Once you have selected your preferences, press the check mark button near the middle of the screen (Figure 6.9). This saves the settings
and takes you back to the input screen to start your session.
6.8 Session Running
When a session is started you will hear a quiet humming sound, see bubbles in the glass container, and, if the lights are turned on, see the
illumination of the water in the glass container.
If the water is bubbling, the device is operating correctly. If it is not bubbling, check to make sure the humidifier is correctly seated in the back
of the device and that the glass container is firmly screwed into the glass container holder. Correctly seating the humidifier also minimizes
the noise.
7 Operating in Standard Mode
All three NanoVi™ devices can be operated in standard mode. Once the device is turned on, a splash screen appears. A self-test runs for 10
seconds with progress shown by the bar at the bottom of the screen. (Figure 7.1)
Upon completion of the self-test, an input screen appears allowing you to enter the amount of time for the session (Figure 7.2). Enter the
desired session time by touching the appropriate numbers on the touch screen. Time is entered in minutes. The minutes entered shows in
the session time indicator in the centre of the screen. Touching the “C” clears a number that has been entered, allowing you to change your
input.
The “M” on the input screen lets you save the amount of time in the memory of the device as the default session time. The amount of time
most recently saved in memory will be displayed instead of “0 min” in the time indicator for all future sessions. The default time in memory
can be reset to zero or to a different default time at any point while the input screen is displayed.
Once the correct amount of time is entered, touch the blue start button to begin the session.
Figure 7.3 shows the screen when the session is in progress. The digital clock counts down the minutes and seconds remaining in the
session. The rotating dots to the left indicate that a session is in progress.
The pause button allows you to interrupt a session (Figure 7.4). Pressing the start button restarts a paused session. If a session has not
been restarted within 15 minutes, the device will automatically turn off.

Figure 7.2.
8 Operating in SmartCard Mode
SmartCard mode is available in the NanoVi Exo™ and NanoVi Pro™ devices, not the Eco device. Skip to Section 9 if you have a NanoVi
Eco™ device.
Insert SmartCards with the arrow showing on the top of the card pointing into the device. The metallic chip must be facing down for the card
to work.
Two types of SmartCard are used to operate the device. The Owner Card is used to put the device in SmartCard mode, to program
preferences, and to load User Cards with minutes. The User Card is used to operate the device when it is in SmartCard mode. A 4-digit code
is printed on the Owner and User Cards that come with the device. This 4-digit code is unique and specific to the device it comes with. The
User Cards will only work with the device that was used to program them.
8.1 Owner Card
The owner card can be inserted any time when the device is turned on. It overrides the current functions and presents the administrative
screen shown in Figure 8.1. The Owner Card has three basic functions: 1) set preferences on the device, 2) set the operation mode of the
device, and 3) program User Cards. Each of these functions is described below. The Owner Card administration screen also shows the rent
time (number of minutes of use) and allows you to reset the rent time by pressing the circular arrow at the bottom of the screen.
1) Setting Preferences
Adjust the volume of the tone that sounds when you touch the screen by touching the + or –symbol. Repeatedly touching the –symbol will
reduce the volume until the sound is turned off completely.
Adjust the brightness of the screen by touching the appropriate + or –symbols. It is not possible to turn the screen off completely.
2) Setting Operation Mode
The Owner Card administrative screen allows you to set the operation mode of the Exo or Pro device. It can be operated in four different
ways: timer mode, infinity mode, User Card timer mode, and User Card session mode. These options are described below.

to select infinity mode.
3. User Card timer mode –requires a User Card and allows the user to enter the
session time. Select the SmartCard option by touching the bottom button.
4. User Card session mode - requires a User Card and has a predetermined
session time. Select both timer mode and User Card session mode to
configure the device in User Card session mode. Enter the desired session
time by pressing the plus and minus arrows of timer mode. Select both the
top and bottom buttons for this option.
Once you have selected one of the four operation modes listed above, press the page up arrow in the lower right corner of the Owner Card
administration screen. The device goes to the operating mode that was selected and the owner card can be removed.Selecting the page
down arrow in the lower right of the Owner Card screen will take you to the screen for programming User Cards, shown below.
3) Programming User Cards
The screen shown in Figure 8.4 indicates that you should insert a User Card to be loaded with minutes. Remove the owner card and insert
the first User Card to be loaded. To return to the Owner Card screen press the page up arrow on the right.
When the User Card is inserted, the screen shown in Figure 8.5 is displayed. The number of minutes on the card can be seen at the top,
above the SmartCard symbol. Selecting the + or –before entering the number of minutes through the touch screen, lets you add or subtract
minutes on the card. Minutes that were already on the card can be reduced or eliminated. Once the desired number of minutes shows in the
bottom display, press the load card button to load the User Card. Remove the User Card and insert the next one, if you are loading multiple
User Cards.

The screen shown in Figure 8.7 is displayed when the NanoVi Exo™ or Pro device is configured in User Card timer mode. The SmartCard
symbol shows a User Card is inserted. The card time shows the number of minutes remaining on the User Card. The session time display
shows the number of minutes entered as the default session time.
The session time display shows 0 min, the desired session time must be input through the touch screen. After entering the time, press the
start button. The session time will count down and minutes will be deducted from the card.
User Card sessions can be stopped at any time by pressing the stop button. Stopping the session takes you back to the initial entry screen
shown in Figure 8.3. Pausing or stopping a session does not affect the number of minutes left on the card.
Session Mode
The device can be set up with a predetermined session time. In this case the session time shows, and no keyboard is visible (Figure 8.8). In
the example below the session time is 30 minutes and the user has 60 minutes left on their card. Although the time cannot be adjusted, it is
still possible to pause or stop a session and to restart a paused session within 15 minutes of touching the pause symbol.
If the User Card is removed at any time while the device is in SmartCard mode, the device will stop operating and display the initial
SmartCard mode screen shown in Figure 8.6.

15 Troubleshooting
15.1 Normal Operation
As soon as the NanoVi™ device starts operation, the air pump is switched on and the glass container is illuminated. At the same time the
water starts to bubble and a humming from the air pump can be heard.
If the pump is not humming and the water in the humidifier is not bubbling, the air pump is not working.
If the pump is humming but the water in the container is not bubbling, the humidifier has not been correctly inserted into the device.
Reseating the connection may resolve this problem. It is also possible that the glass container is not tightly screwed into the glass container
holder. Note: Figure 5.4 or 5.5 to see how the connection should be made.
If the pump creates little or no airflow, the effectiveness of the device is compromised. Refer to the error codes below or contact customer
support.
