ntended Use
This de ice automatically measures human’s Systolic, Diastolic blood
pressure and heart rate by using the oscillometric method during
deflation. All alues can be read out in one LCD panel. Measurement
position is at human being’s wrist. The intended use of this
o er-the-counter de ice 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.
HL158B1-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 le el.
Besides, the de ice features a built-in "Bluetooth Data Transmission"
function, which enables the de ice automatically transmit measuring
results to paired Bluetooth-enabled de ice. 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 de ice.
Additionally, the Wrist Position Guide is used as an aid in determining
if the de ice is at correct position in relationship to the heart.

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
e aluate the status of a patient's blood pressure.
Many factors such as physical acti ity, 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 e ening.
It is on a erage lower in the summer and higher in the winter.
2. Why Is It Useful to Measure Blood
Pressure at Home?
Ha ing 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 ner ous 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 inter al), three times a day for three days.
After three days you can a erage all the results and this will gi e
you an accurate idea of what your blood pressure really is.

About Blood Pressure
A. AHA Blood Pressure Classifications:
Standards for assessment of high or low blood pressure without
regard to age, ha e been established by the American Heart
Association (AHA 2017), as shown in the chart.
Howe er, this chart is not exact for classification of blood
pressure and it's intended to be used as a guide in understanding
non-in asi e blood pressure measurements. Please consult with
your physician for proper diagnosis.
B. Variations in Blood Pressure:
Indi idual blood pressures ary greatly both on a daily and a
seasonal basis. These ariations are e en 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 ariations in blood pressure o er
a whole day with measurement taken e ery fi e 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.

HL158B1-BD Automatic Wrist Blood Pressure Monitor measures
blood pressure and heart rate by oscillometric method, meaning the
fluctuations in pressure are measured. Once the cuff is wrapped
around your wrist, just turn on the monitor and inflation
automatically starts. The inflation of the cuff creates pressure around
the arteries inside the wrist.
Within the cuff is a gauge which senses the fluctuations (oscillations)
in pressure. The fluctuation measured represents the degree of
intensity that your arteries contracting with each heartbeat, and also
a result of the pressure that the cuff has placed on the wrist. The
monitor measures these contractions and con erts the information to
a digital alue. This is the result displayed on the monitor screen.
Once the measurement is complete, the cuff will automatically
deflate.
Note!
* The patient is an intended operator.
Measurement Method

-6-
HL158B1-BD Automatic Wrist Blood Pressure Monitor has been
clinically tested against a scientific de ice called a mercury
sphygmomanometer, considered the gold standard in blood pressure
measurement.
All HL158B1-BD Automatic Wrist Blood Pressure Monitors ha e
performed equi alent to measurements taken with this scientific
de ice and are within the accuracy limits prescribed by the American
National Standard for Electronic or Automated
Sphygmomanometers.
The SPHYGMOMANOMETER was clinically in estigated according to
the requirements of ISO 81060-2:2018.
* n case it is needed to have the device checked for
calibration, please consult the distributor.

 The de ice 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. E en your blood pressure reading is within the "normal"
range, the de ice cannot exclude the diagnosis of Hypertension.
 Do not take a measurement in a low (less than 41˚F / 5˚C) and
high (more than 104˚F/ 40˚C) 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’ e just
consumed caffeinated be erages or smoked cigarettes.
 Rest at least 5 ~ 10 minutes before taking a measurement.
 To allow your blood essels 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 en ironment at
room temperature.
 Do not mo e or shake the de ice during a measurement. Please
keep quiet and do not talk during measurements.
 The de ice has no any interface to pro ide updates/upgrades and
therefore de ice is no security ulnerabilities.
Precautions
* Read the Instruction Manual thoroughly before measuring and
keep it at hand for your reference at any time.
* The de ice is designed for home use and not suitable for clinical
use.
* The patient is an intended operator, who can operate the de ice
by himself or herself, not necessarily by a physician or operator.
* This monitor is not intended for use in the MR en ironment.

 Currently in a dialysis treatment
 In pre-eclampsia condition
 For those who ha e had a mastectomy or lymph node clearance, it
is recommended to take a measurement on the unaffected side.
 When used among medical electronic equipment on the same limb,
pressurization of the cuff may cause temporarily malfunction to
other de ices.
 If you ha e one of the circulatory problems as arteriosclerosis,
diabetes, li er disease, kidney disease, se ere hypertension,
peripheral circulation……, please consult your healthcare
professional before using the de ice.
 Blood pressure measurements taken with this de ice are
equi alent to those obtained by a trained obser er using the cuff /
stethoscope auscultation method and are within the accuracy
limits prescribed by the Standard of EN 1060-4.
 The applied part is cuff.
*Attention !
1) Do not use the de ice on infants, children, or those who cannot express their own intention.
2) The medical de ice should not be used adjacent to or stacked with other equipment. When
the blood pressure monitor are used in a high le el radio frequency electromagnetic fields
(e.g. close to the wireless communication equipment), it may lose or degrade essential
performance, such as de ice gi ing the error code, de iated readings, or malfunction.
3) Consider the electromagnetic compatibility of the de ice (ex. power disturbance, radio
frequency interference etc.) Please use it indoor only.
4) O er 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 wrist. In general, these symptoms should not last long. Howe er, if you
do not reco er in time, please seek your medical practitioners for help.
