1About Kito
Welcome and thanks for your purchase!
We are glad that you are a part of the Kito family now.
Kito is a hand-held medical device that measures body vitals in adults. It measures human skin
temperature, oxygen saturation of arterial hemoglobin (SpO2), respiration rate, heart rate and
electrocardiographic activity (ECG).
Kito uses a 1 Lead ECG mechanism to capture ECG; an NTC thermistor based sensor to measure skin
temperature; and reflective SpO2 technology to measure blood oxygen saturation. Heart rate is
calculated using the ECG values. Respiration rate is derived from the ECG and Photoplethysmography
(PPG) values. Kito connects to the Kito mobile app through Bluetooth Low Energy (BLE)
technology. The recorded measurements are displayed in the Kito mobile app and stored on a
secure Azync Cloud Platform. For indoor use only and non-water resistance.
2Important Information

5Your Health Data
5.1 Know your Vitals
Before proceeding further, let us quickly understand what the vitals measured by Kito mean:
Heart Rate - Heart Rate is the number of times your heart beats in a minute and is an important
indicator of cardiovascular fitness. The Heart Rate of a healthy adult in a relaxed state, lies in the
range of 60 to 100 beats per minute.
Skin Temperature - Skin Temperature majorly depends on the surrounding air temperature and time
spent in an environment. External factors such as chilly winds and humidity can cause changes in the
skin temperature.
Electrocardiogram (ECG) - ECG, alternatively known as EKG, is a test that records the heart's
electrical activity. In simple terms, the heart's activity is captured and plotted on a waveform graph.

Instructions for Use AZOI_KITO_IFU_v1.33
AZOI/FM/IFU/018 Rev 01 AZOI Proprietary and Confidential Page 13 of 35
Blood Oxygen Saturation (SpO2) - SpO2 is a percentage of Oxygen Saturation in the blood. For an
adult, the blood oxygen level should ideally range from 95 to 100 percent in a relaxed state.
Respiration - The Respiration Rate is the number of breaths taken per minute. Normal Respiration
Rate for an adult in a relaxed state, ranges from 12 to 18 breaths per minute. Take a deep breath and
read on.
Note: A more detailed explanation regarding the vitals can be found in the Kito mobile app. Go to
Settings ( )and tap “About Vitals” for additional information.
5.2 The Dashboard
Dashboard is your personalized space to take a new reading, look up the existing readings, and
modify default settings.
Timeline: The Dashboard timeline displays dates of the current month sequentially along a line. You
can slide the timeline to move back and forth and review older readings. The dots adjacent to
the dates expand and shrink based on the number of readings taken during a day- a larger dot
denotes multiple reading records.
Reading Card: One reading card holds the details of a single reading. Reading cards corresponding to
the date selected in the timeline, will be visible at the bottom of your screen. If you have taken

Instructions for Use AZOI_KITO_IFU_v1.33
AZOI/FM/IFU/018 Rev 01 AZOI Proprietary and Confidential Page 14 of 35
multiple readings on a single day, the latest reading will be visible and the rest of the reading
cards will remain collapsed under the Reading Card area.
Share Readings: To share readings, tap “Share” and select the Reading Cards you would like to send
via email. You can share up to 20 readings via email.
Settings: Tap Settings ( )to set a reminder, edit your Profile, sync Fitbit™, apply a security
lock, register email addresses to share reports, apply ECG Filter, alter the measurement unit for
the temperature vital and upgrade Firmware.
Note: Kito and the mobile device must be sufficiently charged before upgrading the firmware. Once
you initiate the firmware upgrade, you will not be able to access the application until the
firmware installation is complete.
5.3 Readings by Type
The graphical representation of readings helps you compare your readings taken over a course of
time. Tap a vital of your preference to see its corresponding graph after you have taken a reading. To
review an older reading, go to the Dashboard and select the date for which you want to look up the
readings. Tap individual reading cards to expand and view the details.
5.3.1 Heart Rate
Tap Heart Rate to plot heart rate value on the chart. Here, the X-axis (horizontal) corresponds to the
hours/day/month units, and the Y-axis (vertical) corresponds to the measuring unit for Heart Rate
which is BPM.

Instructions for Use AZOI_KITO_IFU_v1.33
AZOI/FM/IFU/018 Rev 01 AZOI Proprietary and Confidential Page 15 of 35
The values on Y-axis show the range for Heart Rate.
Note: The range shown in the application is only a reference and may not apply to everyone. Consult
your doctor to know the appropriate range for you.
The point plotted on the graph denotes a single reading. The reading which you are reviewing will be
displayed at the center of the screen.
The value in percentage at the top-right of your screen represents the percentage difference
between your latest reading and the one being reviewed.
The app overlays the information received from Fitbit™ over its own reading of vitals to indicate how
your daily activity is affecting your vitals.
The line graph which is a series of data points connected by lines, illustrates Fitbit™ data. For each
Fitbit™ step count data, you can see the corresponding vital statistics taken from Kito overlaid on the
graph.

This is what you will typically see in an ECG display. The X-axis (horizontal) corresponds to the time in
seconds, and Y-axis (vertical) corresponds to the amplitude or voltage in millivolts (mV). The graph
highlights a repeating pattern of a tiny wave, followed by a sharp dip, a tall and a sharp spike,
followed by a moderate sized wave. This wave pattern represents a single cardiac cycle.
To enhance the ECG graph, you can apply filter to remove noises from the ECG signal. Go to Settings,
tap “ECG Filter” switch to toggle it ON or OFF.
Accurate ECG interpretation is complex and involves interpretation of several other parameters in
tandem. Hence, we recommend that you show your ECG results to an expert in the relevant medical
field for an in-depth analysis and interpretation of the results.
