About Blood Pressure
This manual and product do not substitute for advice provided by your doctor.
You must not use the information contained herein, or this product for diagnosing or
treating a health problem or prescribing any medication. If you suspect that you have
a medical problem, promptly consult your healthcare provider.
This device uses the oscillometric method to automatically measure systolic and
diastolic blood pressure as well as heart rate.
The measurement position is at human being’s arm.
All values can be read out in one LCD panel.
The device is designed for home use and recommended for use by adults aged 18
years and older with upper arm circumference ranging from 9 ~13” (approx. 23 ~ 33 cm).
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 uctuating 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 inuence 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 specic time of day.
This is why medical practitioners recommend home monitoring as it is important to get

IWMP540 USER MANUEL
4
readings of blood pressure during dierent 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 1 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 classications:
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
classication 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 ve minutes.
The thick line represents sleep. The rise in blood
pressure at 4 PM (A in the graph) and 12 PM (B in
the graph) correspond to an attack of pain.

Precautions
• 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.), or
you may get inaccurate readings.
•Wait 30 ~ 45 minutes before measurement if you’ve just consumed caein-included
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
waiting time according to your personal physiological situation.
•We recommend you using the same arm (preferably the left arm) and measuring
around the same time each day.
• Sit down comfortably and place your elbow on the table with your feet at on the oor.
Please do not cross your legs during measurements.
• Keep the device at heart level. Relax your hand with the palm facing up.
• Perform measurements in a quiet and relaxed environment at room temperature.
• Do not move or shake the device during a measurement. Please keep quite and do not
talk at the same time.
*Do not use this manual and product as a substitute for advice, diagnosing or
treating a health problem or prescribing any medication by your doctor. If you have
a medical problem, promptly consult your healthcare provider.
*Read the Instruction Manual thoroughly before measuring and keep it at hand for
your reference at any time.
*This device uses the oscillometric method to measure systolic and diastolic blood
pressure as well as your heart rate. It’s recommended for use by people over the age
of 18 and not to be used on infant or children.
*The device is designed for home use and not suitable for clinical use.

Precautions
• Keep in mind that blood pressure naturally varies from time to time throughout the
day and is aected by lots of dierent factors such as stress, eating, smoking, alcohol
consumption, medication, and physical activity, etc.
Normally the blood pressure rises while at work and is at its lowest during sleeping period.
• Blood pressure measurements should be interpreted by a physician or a trained health
professional who is familiar with your medical history. Using the unit and recording the
results regularly for your physician to interpret, you will keep your physician informed of
the continuing changes in your blood pressure.
• 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.
• This product is not suitable for people with arrhythmias and pregnant women.
• Blood pressure measurements taken with this device are equivalent to those obtained
by a trained observer using the cu / stethoscope auscultation method and are within the
accuracy limits prescribed by the Standard of EN 1060-4.
*Attention !
1.. Do not use the device on infants, children, or those who cannot express their
own intention.
2. The device is equipped with sensitive electronic components. While measuring,
avoid strong electrical or electromagnetic elds, e.g. mobile phones, microwave
ovens, etc; or it may lead to temporary reading error or inaccuracy.
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 ow 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. However, if you do not recover in time, please seek your
medical practitioners for help.

*Attention !
• 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 to take medical advice
• As a safeguard, we recommend that if you have arrhythmias such as atrial or
ventricular premature beats and atrial brillation 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 lter the unstable
status of user and avoid aecting 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 dierent from a strict
mathematical averaging of all recorded intervals.
• At least 3 beats with at least 25% dierence from the average heart beat interval
will generate the IHB icon on the screen.
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 dened 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.
