Intended Use
This device automatically measures human’s Systolic, Diastolic blood
pressure and heart rate by using the oscillometric method during
deflation. All values can be read out in one LCD panel. Measurement
position is at human being’s wrist. The intended use of this
over-the-counter device is for adults aged 18 years and older with
wrist circumference ranging from 5.3 inches to 7.7 inches (approx.
135 mm to 195 mm) and for home use.
HL158AU-BD detects the appearance of irregular heartbeats during
measurement; an indicated symbol will appear with measuring
reading. And the Risk Category Indicator will show the information
with the readings on the screen for the user tracking their blood
pressure level.
Besides, the device features a built-in "Bluetooth Data Transmission"
function, which enables the device automatically transmit measuring
results to paired Bluetooth-enabled device. Also, users could simply
synchronize the current date and time, and check the battery status
of blood pressure monitor by means of DailyChek® application
software with the paired Bluetooth-enabled device.
Additionally, the Wrist Position Guide is used as an aid in determining
if the device is at correct position in relationship to the heart.

About Blood Pressure
1. What is blood pressure?
Blood pressure is the measurement of the force of blood pushing
against the walls of the arteries. Arterial blood pressure is
constantly fluctuating during the course of the cardiac cycle. The
highest pressure in the cycle is called the systolic blood pressure,
and represents the pressure in the artery when the heart is beating.
The lowest pressure is the diastolic blood pressure, and represents
the pressure in the artery when the heart is at rest. Both the
systolic and the diastolic pressure are necessary for a physician to
evaluate the status of a patient's blood pressure.
Many factors such as physical activity, anxiety or the time of day,
can influence your blood pressure. Blood pressure is typically low
in the mornings and increases from the afternoon to the evening.
It is on average lower in the summer and higher in the winter.
2. Why is it useful to measure blood pressure
at home?
Having one's blood pressure measured by a doctor in a hospital or
a clinic, is often associated with a phenomenon called “White Coat
Hypertension” where the patient becomes nervous or anxious,
thus raising his blood pressure. There are also numerous other
factors that might cause your blood pressure to be raised at a
specific time of day. This is why medical practitioners recommend
home monitoring as it is important to get readings of blood
pressure during different times of the day to really get an idea of
your real blood pressure.
Medical practitioners generally recommend the “Rule of 3”, where
you are encouraged to take your blood pressure three times in a
row (at 3 ~ 5 minute interval), three times a day for three days.
After three days you can average all the results and this will give
you an accurate idea of what your blood pressure really is.

About Blood Pressure
A. WHO blood pressure classifications:
Standards for assessment
of high or low blood pressure
without regard to age, have
been established by the World
Health Organization (WHO),
as shown in the chart.
However this chart is not
exact for classification of blood pressure and it's intended to be
used as a guide in understanding non-invasive blood pressure
measurements. Please consult with your physician for proper
diagnosis.
B. Variations in blood pressure:
Individual blood pressures vary greatly both on a daily and a
seasonal basis. These variations are even more pronounced in
hyper tense patients. Normally the blood pressure rises while at
work and is at its lowest during sleeping period.
(hyper tense: means a person who has high blood
pressure symptom.)
The graph below illustrated the variations in blood pressure
over a whole day with measurement taken every five minutes.
The thick line
represents sleep.
The rise in blood
pressure at 4 PM (A
in the graph) and
12 AM (B in the
graph) correspond
to an attack of
pain.

Precautions
The device should not be used to either self-diagnose Hypertension
or exclude the diagnosis of Hypertension. If your blood pressure
reading is out of normal range, please consult your physician. Even
your blood pressure reading is within the "normal" range, the
device cannot exclude the diagnosis of Hypertension.
Do not take a measurement in a low (less than 41 ℉/5 ℃) and
high (more than 104 ℉/40 ℃) temperature, nor in a place outside
humidity ranges (15 % ~ 93 % R.H.), and atmospheric pressure
ranges (700 ~ 1060 hPa), or you may get inaccurate readings.
Wait 30 ~ 45 minutes before measurement if you’ve just
consumed caffeinated beverages or smoked cigarettes.
Rest at least 5 ~ 10 minutes before taking a measurement.
To allow your blood vessels to return to the condition prior to
taking the measurement, please wait at least 3 ~ 5 minutes in
between measurements. You may need to adjust the wait time
according to your personal physiological situation.
We recommend you using the same wrist (preferably the left wrist)
and measuring around the same time each day.
Perform measurements in a quiet and relaxed environment at
room temperature.
Do not move or shake the device during a measurement. Please
keep quiet and do not talk during measurements.
The device has no any interface (e.g. USB) to transfer data or
provide updates/upgrades and therefore device is no security
vulnerabilities.

*Attention
！
1. Do not use the device on infants, children, or those who cannot express their
own
intention.
2. The medical device should not used adjacent to or stacked with other
equipment.
When the blood pressure monitor are used in a high level radio
frequency electro
magnetic fields (e.g. close to the wireless communication
equipment), it may lose or degrade essential performance, such as device
giving the error code, deviated readings, or malfunction.
3. Consider the electromagnetic compatibility of the device (ex. power
disturbance, radio
frequency interference etc.) Please use it indoor only.
4. Over high frequency measurements may result in blood flow interference,
which is
likely to cause uncomfortable sensations, such as partial subcutaneous
hemorrhage, or
temporary numbness to your arm. In general, these
symptoms should not last long.
However, if you do not recover in time, please
seek your medical practitioners for help.
Precautions
For those who have had a mastectomy surgery or lymph node
clearance, it is recommended to take a measurement on the
unaffected side.
When used among medical electronic equipments on the same
limb, pressurization of the cuff may cause temporarily malfunction
to other devices.
If you have one of the circulatory problems as arteriosclerosis,
diabetes, liver disease, kidney disease, severe hypertension,
peripheral circulation……, please consult your healthcare
professional before using the device.
Blood pressure measurements taken with this device are
equivalent to those obtained by a trained observer using the cuff /

Features
Irregular Heartbeat Detector
The symbol will appear on screen indicating a certain
heartbeat irregularity was detected during measurement.
The heartbeat rhythm that is more than or less than 25% from the
average rhythm is usually defined as an irregular heartbeat rhythm.
Talking, moving, shaking or an irregular pulse during the
measurement can result in the appearance of this symbol.
Usually this is not a cause for concern, however if the symbol
appears often, we recommend you seek medical advice.
And please note that the device does not replace a cardiac
examination, but serves to detect pulse irregularities at an early
stage.
*Note ！
The pulse display is not suitable for checking the frequency of heart
pacemakers. If a certain pulse irregularity is detected during measurement
often, we recommend you seek medical advice
As a safeguard, we recommend that if you have arrhythmias such as atrial or
ventricular premature beats and atrial fibrillation or any other special
conditions you should check with your physician before using your device.
The IHB function is not designed for use by people with arrhythmias nor for
diagnosing or treating an arrhythmic problem. In order to filter the unstable
status of user and avoid affecting the detection of heart rate from any
movement, shaking or talking in the beginning of measurement, the method of
averaging heart beat intervals of subject device is calculated with the three
proper heart beat pulses detected in the beginning of measurement and that is
different from a strict mathematical averaging of all recorded intervals.
At least 3 beats with at least 25 % difference from the average heart beat
interval will generate the IHB icon on the screen.
