1.
Relax your arm with your palm facing
upwards and tie the cuff around your
upper arm, and then align the Artery
indicator with the main Artery (on the
inside of your arm).
Note: Locate the main Artery by gently pressing
with 2 fingers above the inside of your elbow
(approx. 2 cm). Identify where the pulse can be
felt the strongest and that is your main Artery!
4. Make sure the bottom edge of the
arm cuff is 2 to 3 cm above the inside of
the elbow. Then wrap the cuff securely.
Note: The cuff should be snug but not too tight.
You should be able to insert one finger between
the cuff and your arm.
Remove all jewelry (such as watches and
bracelets) from your left arm.
Note: If your doctor has diagnosed you with poor
circulation in your left arm, please use your right arm.
Roll or push up your sleeve to expose
your upper arm. Make sure your sleeve
is not too tight.

6.
Sit upright in a comfortable chair with your
back resting against the backrest of the chair.
Keep your feet flat and your legs uncrossed.
Place your arm resting comfortably on a flat
table. The cuff worn on your arm should be
placed at the same level as your right atrium
of the heart.
Take 5-6 deep breaths and start measuring!
Measure in a quiet place.
Wait at least 3 minutes before another measurement. This allows your blood circulation to recover.
Relax and do not move or talk during measurement.
For a meaningful comparison, try to measure under similar conditions. For example, take daily
measurements at approximately the same time, on the same arm or as directed by a physician.
Rest for 5 minutes before measurement.

ABOUT BLOOD PRESSURE
What are systolic pressure and diastolic pressure?
What is the standard blood pressure classification?
When ventricles contract and pump
blood out of the heart, the blood
pressure reaches its maximum value
in the cycle, which is called systolic
pressure. When the ventricles relax,
the blood pressure reaches its
minimum value in the cycle, which is
called diastolic pressure.

CAUTION
Only a physician can tell your normal BP range. Please contact a physician if your
measuring result falls out of the range. Please note that only a physician can tell
whether your blood pressure value has reached a dangerous point.
Irregular Heartbeat Detector
An irregular heartbeat is detected when a heartbeat rhythm varies while the unit is
measuring the systolic and diastolic blood pressure. During each measurement, the
monitor records all the pulse intervals and calculates the average; if there are two or
more pulse intervals, the difference between each interval and the average is more
than the average value of ±25%, or there are four or more pulse intervals, the
difference between each interval and the average is more than the average value of
±15%, the irregular heartbeat symbol appears on the display when the measurement
results appeared.
CAUTION
The appearance of the IHB icon indicates that a pulse irregularity consistent
with an irregular heart beat was detected during measurement. Usually, this is
NOT a cause for concern. However, if the symbol appears often, we recommend
you seek medical advice. Please note that the device does not replace a cardiac
examination, but serves to detect pulse irregularities at an early stage.
Why does my blood pressure
fluctuate throughout the day?
Is the result the same
if measured on the
right arm?
Why do I get a different
blood pressure at home
compared to the hospital?
1. Individual blood pressure varies multiple
times every day. It is also affected by the
way you tie the cuff and your measurement
position, so please measure under the same
conditions.
2. If the person takes medicines, there will
be greater variation in blood pressure.
3. Wait at least 3 minutes for another
measurement.
The blood pressure is different even
throughout the day due to weather,
emotion, exercise, etc. Also, there is
the “white coat” effect, which means
blood pressure usually increases in
clinical settings.
It is ok for both arms, but there will be
some different results for different
people. It is recommended that you
measure the same arm every time.
What you need to pay attention
to while measuring your blood
pressure at home:
If the cuff is tied properly.
If the cuff is too tight or too loose.
If the cuff is tied on the bare
upper arm.
If you feel anxious.
Taking 2-3 deep breaths before
starting will be better for
measuring.
Advice: Relax for 4-5 minutes
until you calm down.
