GET STARTED
You now have ScanWatch, the most advanced health wearable ever
designed. It is the first-ever hybrid smartwatch to notify users that
they are at risk for highly prevalent yet underdiagnosed conditions,
including breathing disturbances and atrial fibrillation. Nested in a
high-end watch, state-of-the-art medical technology has been
carefully selected to create the most health-oriented watch ever
offered to the public.
Developed with cardiologists, and clinically validated, this is the
world's first hybrid smartwatch that can alert a user to a possible
case of atrial fibrillation or breathing disturbances. ScanWatch also
offers in-depth activity and sleep tracking, water resistance to 50m,
and an exceptional battery life of up to 30 days before it needs to be
charged.

SCANWATCH AT A GLANCE
By pressing the digital crown, you can scroll
through data (date, heart rate, steps, distance,
calories burned, elevation), launch measurements
(oxygen saturation levels, electrocardiogram,
workout mode), receive notifications of high, low,
orirregularheartbeat,getsmartphone notifications,
access the alarm, timer & stopwatch if enabled in
the app, and adjust settings via the watch's digital
display.
Data — date, heart rate, steps, distance, calories burned,
elevation
Notifications — heartbeat notifications, smartphone
notifications, silent alarm, goal reached
Launch measurement — oxygen saturation levels,
electrocardiogram, workout mode

12
Check heart rate and receive heartbeat notifications when heart rate
is atypical (low or high) and if signs of atrial fibrillation are detected.
The embedded PPG sensor and our exclusive algorithm analyze
your heart without disrupting your life. You don’t need to launch any
measurements or activate any functionalities. It is automatic.
Heart rate and rhythm measurements are obtained by the exclusive
multi-wavelength PPG sensor using light absorbed by the blood and
skin to measure variation in blood flow to the veins.
3. Heartbeat notifications:
24/7 heart scanning. Invaluable peace of mind.

13
You can receive 3 types of notifications:
• LOW HEART RATE
• HIGH HEART RATE
• ATRIAL FIBRILLATION
Heartbeat notifications will be displayed on ScanWatch and your
smartphone, and you can see a full history of notifications in the
Health Mate app.

14
WHEN SHOULD YOU TAKE A MEASUREMENT?
You should take a measurement after receiving a heartbeat
notification or if you feel palpitations or an irregular heart rhythm
(for example, a rapid or skipped heartbeat).
HOW TO TAKE AN ECG
To record an ECG, sit and rest, press the digital crown to wake up the
watch, scroll in the menu to find the ECG option, press again, then
place your fingers on the front electrode for 30 seconds.
Stay still, don’t move or talk, and relax—it’s best to be seated or to
place your arm on your leg, and try not to contract your arm and
hand muscles. The watch PMOLED screen countdown, and the
watch will vibrate to notify the user that the reading is complete.
The app will display the results of the ECG.

anytime, anywhere

15
RESULTS IN THE HEALTH MATE APP
The electrocardiogram provides 2 types of insights:
- Atrial fibrillation detection, one of the most common arrhythmias,
based on the analysis of sinus rhythm (how the heart beats)
- An indication of your heart rate state telling you if it seems low or
high, which can be associated with bradycardia and tachycardia
NORMAL SINUS RHYTHM: A sinus
rhythm means your heart is beating in a
uniform pattern.
ATRIAL FIBRILLATION:
Atrial fibrillation occurs when the two
upper chambers of the heart move
chaotically instead of pumping
regularly.
The P wave on the ECG disappears and
is replaced by a jumpy baseline. The
QRS complex occurs at "irregularly
irregular" intervals.

16
HIGH OR LOW HEART RATE: Know if
your heart beat is too fast or too slow
with clear results.
INCONCLUSIVE: An inconclusive result
means the recording can’t be classified.
This can happen for many reasons, such
as not resting your arms on a table
during a recording, contracting arm or
hand muscles during measurement, or
if your ECG device is too loose around
the wrist and/or fingers are not in
proper contact with the ring around the
watch face.
Certain conditions, such as a pacemaker
or anatomical variations, may prevent a
small percentage of users from creating
enough signal to produce a good
recording.
SHARE WITH YOUR DOCTOR OR HEALTH PROVIDER
Once your results appear in the Health Mate app, you can share
them with your doctor or health provider by simply tapping “Share
PDF.” A PDF format document will be available to be read by your
specialist to help them with a diagnosis.

exclusive multi-wavelength technology.
HOW TO TAKE A MEASUREMENT
To launch a measurement, sit and rest, press the digital crown to
wake up the watch, scroll in the menu to find the SpO2 option, press
again, then place your fingers on the front electrode for 30 seconds.
Once the measurement is done, ScanWatch will vibrate and the
results will be displayed on the PMOLED screen. More information is
available in the Health Mate app after the watch synchronizes.

RESULTS IN THE HEALTH MATE APP
Get oxygen saturation percentage, history and an indication on
where it stands:
- 100% > X >94%: normal
- 94% > X > 90%: below
average. This could be due to
many factors. More info is
given in the app to help the
user determine the action to
take.
- X < 90%: low. Consult best
practices and repeat the
measurement. Then contact
your doctor or a health
professional, who will help
you make a diagnosis and
take preventive actions.

19
Respiratory Scan can monitor oxygen saturation all night long via
embedded SpO2 sensors, so you can wake to results that show if
any breathing disturbances occurred while sleeping, which can be
associated with apneic episodes.
HOW TO USE THE RESPIRATORY SCAN
The Respiratory Scan builds a complete map of your night. For this
reason, use of the feature will impact battery life. You will be able to
choose among three types of experiences:
- Always on: a Respiratory Scan will be completed
every night, and you will get the results every
morning. Your expected battery life will be greatly
reduced with this mode.
- Automatic: ScanWatch will automatically plan a
Respiratory Scan for three nights in a row once
every quarter. It will notify you the day before and
ask if you want to reschedule later. This frequency
is recommended by doctors to get the best results
from this feature.
- Off: No Respiratory Scan will be launched.
A Respiratory Scan will measure your heart rate, heart rate variability,
respiratory rate and oxygen saturation level throughout the night.
From those metrics, ScanWatch is also able to provide the amount
of breathing disturbances that were experienced during the previous
night.
RETRIEVING YOUR RESPIRATORY SCAN REPORT
You can retrieve a complete report in Health Mate and send it to a
health professional via PDF if needed.
Disclaimer: use of the Respiratory Scan functionality will impact the battery life.

Sleep quality is a key factor in maintaining a healthy lifestyle. We
believe that if you understand your sleep, you can be empowered to
improve it. ScanWatch provides insights into your sleep patterns.
ScanWatch automatically analyzes your sleep, as well as the different
parameters that can affect the quality and quantity of your sleep.
These parameters include:
- Breakdown of your night: time spent awake, duration of light sleep
cycle, duration of deep sleep cycle
- Time spent asleep
- Sleep Score
- Number of wake-ups
- Regularity
- Sleep Heart Rate
- Atrial fibrillation detection
Every morning, when you wake to your Sleep Score in the Health
Mate app, you can learn about parameters that impact your sleep, so
you can know how to improve your nights and your overall well-
being.
The Sleep Score is a very simple and intuitive way to understand
how well you slept. Every night's sleep is rated with the best possible
score being 100 points.
