medical condition or disease. Please consult with your healthcare provider
if you experience unusual readings. Under no circumstances should you
alter the dosage of any medication prescribed by your doctor.
The pulse display is not suitable for checking the frequency of heart
pacemakers.
For cardiac irregularity (irregular heartbeat), measurements obtained with
this device should only be evaluated in consultation with your doctor.
Electromagnetic interference:
The device contains sensitive electronic components (microcomputer). Therefore,
avoid strong electrical or electromagnetic fields in the direct vicinity of the device
(For example: mobile phones, microwaves). These can lead to the temporary
impairment of measurement accuracy.
Chapter 2 Important information about blood pressure and its
measurement
2.1 How does high blood pressure arise?
Blood pressure and heart rate are controlled by the lower portion of the
brainstem called medulla oblongata. Blood pressure is dynamic and responds to
respective situation by way of feedback mechanism via the nervous system. To
adjust for blood pressure, the strength and frequency of the heart (pulse), as well
as the width of circulatory blood vessels respond by changing. The latter is
affected by way of fine muscles in the blood vessel walls. The level of arterial
blood pressure changes periodically during the heart activity: During blood
ejection (Systole), the value is maximal (systolic blood pressure value); at the end
4
of the heart’s rest period (Diastole), the value is minimal (diastolic blood pressure
value). For a healthy adult, the blood pressure values should lie within certain
range (see below).
2.2 Blood pressure values classification
According to American Heart Association (AHA) guidelines in 2017, blood pressure
values are classified into 4 levels, as shown in the table below.
Note: ESH/ESC guidelines may vary. Consult your healthcare provider for
region-specific guidelines and information.
Further information:
If your blood pressure values are mostly in the normal range under resting
conditions but exceptionally high under conditions of physical or
psychological stress, it is possible that you are suffering from a medical
condition called labile hypertension. Please consult your healthcare
5
provider if you suspect this to be the case.
Correctly measured diastolic blood pressure values of above 110mmHg will
require immediate medical treatment.
There are measures you can take to prevent and/or reduce medically established
high blood pressure.
A. Eating habits
Strive for a normal weight for your age and height
Avoid excessive consumption of table salt
Avoid fatty food
B. Existing illnesses
Follow consistently any medical instructions for treating existing illnesses,
such as diabetes (diabetes mellitus), fat metabolism disorder, gout, etc
C. Habits
Restrict caffeine consumption, such as coffee
Drink only moderate amount of alcohol
Avoid smoking
D. Physical activities
Exercise regularly
Choose sports that require stamina over those that require strength
Do not over exert and/or avoid reaching the limits of your performance
If you have a pre-existing condition and/or you are over 40, please consult
your healthcare provider before starting any physical activities
2.3 SmartCheck™technology
SmartCheck™technology is an innovative concept to achieve optimum reliability
in self-measurement of blood pressure. Highly accurate measurement result is
achieved by the automatic analysis of three successive measurements (see
section 5.5 Measuring procedure). As human blood pressure is dynamic and can
fluctuate, the SmartCheck™technology provides a convenient way to obtain an
accurate measurement, even during arrhythmia. This results in greater accuracy
when compared to the calculation of average result.
6
Measurement specification:
The total measurement time for a full measurement cycle is less than 3
minutes, as opposed to a single measurement time of about 1.5 minutes.
Single results are not displayed.
Based on data analysis result, a 4th measurement may be applied.
2.4 Irregular heartbeat detection (IHD)
The appearance of the symbol indicates that certain pulse irregularity is
detected during measurement. This may cause results to vary from your normal
blood pressure levels. In general, this is not a cause for concern. However, if the
symbol appears more frequently than usual, it is recommended that you consult
with your healthcare provider.
If SmartCheck™measurement mode is used, irregular heartbeat detected during
measurement will not affect results (see section 2.3 for more information).
Note: The device detects early stage pulse irregularities. It is not a replacement
for cardiac examination.
2.5 Traffic light indication
The colored bars on the left edge of the display indicate the range within which
the measured blood pressure values lie. Depending on the height (or number) of
the bars, the measured values are either within the normal (green),
elevated/hypertension stage 1 (yellow) or hypertension stage 2 (orange/red)
range. The classification corresponds to the 4 levels as defined by the American
Heart Association (AHA). Please refer to the table in section 2.2 to learn more.
In addition, the 3-color backlight display shows different color according to the
measured blood pressure values. Readings in the classification range of 1 is shown
in green backlight, classification ranges of 2, 3 in yellow backlight and
classification ranges of 4, 5, 6 in red backlight.

Chapter 5 Operating the blood pressure monitor
5.1 Before taking measurement
Avoid eating, smoking and any strenuous activity such as exercise before
measurement. These factors can influence the measurement result. It is
recommended that you relax for about ten minutes before measurement.
Example: sitting in an armchair in a quiet environment.
Remove any tight or constricting garment around upper arm.
Always measure from the same arm –typically left arm.
Attempt/plan to carry out measurement regularly around the same time of
day as blood pressure changes during the course of the day.
5.2 Common sources of error
Note: Comparable blood pressure measurements require and/or are
dependent on the same conditions.
Any effort by the user to support his/her arm during measurement can
increase the blood pressure values. Therefore, make sure that the user is in
a comfortable, relaxed position and does not activate any muscles of the
arm during measurement. Use a cushion for support if necessary.
If the arm artery lies considerably lower (higher) than the heart, an
erroneously higher (lower) blood pressure will be registered. Each 15 cm
(5.9 inches) difference in height results in a measurement error of about
10mmHg.
Arm cuff that is too narrow or too short will result in false measurement
values. Using the correct size cuff is crucial in getting accurate
measurement values. The cuff size is dependent on the circumference of
the arm, measured at the center.
Note: only use Vaunn® Medical arm cuff.
A loose cuff or sideway protruding air pocket causes false measurement
values.
Repeated measurements cause blood to accumulate in the arm. This can
lead to false results. Therefore, it is recommended to pause for at least 1
minute between measurements.
14
5.3 Fitting the arm cuff
a. Pass the end of the cuff (with sewn-in rubber stopper)
through the metal D-ring to form a loop. The Velcro
closure should be facing outward. If assembled correctly,
the metal D-ring should not touch the skin when the cuff
is looped around the arm.
Note: Skip this step if the cuff has already been
prepared.
b. Insert left arm through the cuff loop and position the
cuff on the upper arm. The tube should point in the
direction of the lower arm.
c. Adjust the cuff position on the upper arm. The lower
edge of the cuff should be approximately ¾-1” (2-3cm)
above the elbow. The tube and “ARTERY MARK” should
be aligned with the inner side of the arm.
Important: The red line along the edge of the cuff must
lie exactly over the artery which runs down the inner
side of the arm.
d. Tighten the free end of the cuff and secure with the
Velcro closure. The cuff should fit snugly on your upper
arm such that you can fit 2 fingers between the cuff and
your upper arm. Any clothing that restricts the arm
should be removed prior to measurement.
e. Lay the arm on the table or support cushion with the
palm upward. The arm cuff should be at the same level
as the heart. Check to make sure that the tube is not
kinked.
f. Remain seated comfortably for about two minutes
before starting measurement.
15
Note: If it is not possible to fit the cuff on the left arm, it can also be placed
on the right arm. However, for consistency, measurements should only be taken
from the same arm.
5.4 Measurement mode selection
You can choose between single or SmartCheck™measurement mode.
Single mode:
Slide the mode switch (on the right-hand side
of the measuring unit) towards “1”.
In single mode, 1 measurement will be taken.
SmartCheck™mode:
Slide the mode switch towards “3”
In SmartCheck™mode, 3 measurements will be taken in succession and
final results will be calculated automatically.
The symbol on the screen display indicates that the device is set
to measure in SmartCheck™mode.
5.5 Measuring procedure
Before taking measurement, make sure that the arm cuff has been applied and
positioned correctly.
1. Press the Start/Stop button . The pump
will begin to inflate the cuff. The display
shows the increasing cuff pressure during
inflation.
2. The pump will stop once inflation pressure
has been reached. Cuff pressure will start to
decrease slowly. Similarly, the display shows
16
the decreasing cuff pressure during deflation.
3. When the device detects the pulse, the heart
symbol begins to blink on the display and a
beep tone will register with every pulse beat.
4. When measurement is complete, a long beep
tone will register. The measured systolic and
diastolic blood pressure values as well as the
pulse rate are displayed. Traffic light indicator
bars and colored backlight will be displayed
according to the classification ranges in which
the measurement results lie.
5. If the symbol appears on the display, it
indicates that an irregular heartbeat has been
detected during measurement. This may cause
results to vary from your normal blood
pressure levels. It is recommended that you
retake your measurement after a brief pause
of at least 1 minute. It is important that you remain relaxed, still and not
talk during measurement.
Note: If the symbol appears more frequently than usual, it is recommended
that you consult with your healthcare provider.
6. The measurement results will remain on the display until the device is
switched off by pressing the Start/Stop button . If the button is not
pressed within 1 minute, the device will switch off automatically to save
power.
7. If the device is set to SmartCheck™measurement mode, it will take 3
separate measurements in succession and calculate the analyzed blood
