TAKING YOUR BLOOD PRESSURE
HOW UB-521CN WORKS
LifeSource® Blood Pressure Monitors are easy to use, accurate and display
clear digital measurements. Our technology is based on the “oscillometric
method”. The term “oscillation” refers to the measure of vibrations caused
by the arterial pulse and is a non-invasive method to determine blood
pressure.
Tips for Blood Pressure Monitoring:
Our monitors examine the pulsatile pressure generated by the arterial wall
as it expands and contracts with each heartbeat against the monitor’s cuff.
This monitor measures your blood pressure while the cuff is inflating.

before you start
Relax for about 5 minutes before measurement.
Do not smoke or ingest caffeine at least 30 minutes prior to
measurement.
Remove constricting clothing and place cuff on bare wrist.
Unless your physician recommends otherwise, use left arm
to measure pressure.
Do not talk during measurement.
Do not cross legs. Keep your feet flat on floor during
measurement.
Now you are ready. Follow these simple steps:
The UB-521CN provides accurate readings on wrists with a circumference
between 5.3" and 8.5" (13.5 cm and 21.5 cm).
The unit requires two "AAA" (1.5 volt) batteries to operate (alkaline
batteries recommended). To install batteries (or to replace when "Low
Battery" symbol appears), proceed as follows:
1. Slide the battery cover as shown to remove from the device.
2. Insert batteries into designated areas ensuring a correct match with
1. Sit comfortably in a chair near a flat surface.
2. With palm facing upward, attach monitor to the
inside of your left wrist and fasten securely. The top
edge of the cuff should align with the crease of your
wrist.
3. Position your wrist so it is level with your
heart, using an arm rest if needed. Positioning
of the wrist at heart level is critical for accurate
measurement.

3. Return battery cover by sliding back on to monitoring device.
NoTE: Rechargeable batteries will not work with this monitor.
4. Press the START button. Your average blood
pressure reading will appear with the number
of measurements stored in memory (i.e. A25 = total of 25
measurements stored in memory). As the cuff pressurizes,
measurement will begin and the Cuff Inflation Meter will
show on the display screen. It is normal for the cuff to feel
very tight.
NoTE: To stop inflation at any time, press START

Diastolic
The UB-521CN Blood Pressure Monitor provides a blood pressure and
pulse rate measurement even when an irregular heartbeat occurs. The
Irregular Heartbeat symbol
will appear in the display window in
the event an Irregular Heartbeat has occurred during measurement. An
irregular heartbeat is defined as a heartbeat that varies by 25% from the
average of all heartbeat intervals during the blood pressure measurement.
It is important that you relax, remain still and refrain from talking during
measurements.
NoTE: We recommend contacting your physician if you see this
symbol frequently.
Pulse
The device has an automatic power-down feature
which turns off power automatically one minute
after measurement is obtained.
For the most useful blood pressure history, we recommend that you record
the date and time after each measurement. The most accurate history
relies not on a single or sporadic readings, but on a consistent monitoring
pattern over time.
NoTE: If you wish to take your blood pressure measurement again, relax and wait 5-10
minutes to enable the flow of blood in the arm to return to normal.
About cuff inflation METER
The Cuff Inflation Meter is located on the left side of the display screen
to tell you when the blood pressure monitor is inflating the cuff. The Cuff
Inflation Meter moves up during inflation.

About Memory
About Average Reading
The UB-521CN provides an average blood pressure reading
based on the total measurements stored in memory. When
taking a measurement, the average blood pressure reading
will appear and the number of measurements stored in
memory will flash several times before the cuff begins
to inflate. The average blood pressure reading will also
appear briefly when you recall the measurements stored in
memory.
The UB-521CN automatically stores up to (90) blood pressure and pulse
measurements in its memory. Measurements stored in memory are
assigned an index number in the order of the newest to the oldest. The
oldest reading displays as "n01".
To retrieve readings, follow these simple steps:
1. When the display screen is blank, press and hold the
START button. While holding down the START button,
you will see the average reading displayed first. You
will then see the memory index number (e.g. n04) of
the most recent reading followed by the measurement.
Release the START button when you see the memory
index number.

About Pressure Rating Indicator™
The Pressure Rating Indicator™ is a feature
which provides a snapshot of your blood pressure
classification based on your measurements.
This will let you quickly know what your blood
pressure readings mean. Each segment of the bar
indicator corresponds to the Seventh Report of the
Joint National Committee (JNC7) on Prevention,
Evaluation and Treatment of High Blood Pressure
from the National Heart, Lung and Blood Institute
- May 2003. For a more detailed look at this blood
pressure classification, please refer to “Assessing
High Blood Pressure” on page E-11.

remove the battery from the unit and then place the
battery back into the battery holder.
NoTE: Memory will be lost if batteries become low or are removed.
:The indicator displays a segment, based on the current measurement,
corresponding to the JNC7 Classification.
NoTE: Due to other risk factors (e.g. diabetes, obesity, smoking, etc.) in addition to your
blood pressure measurement, the Pressure Rating Indicator is approximate. Please consult
with your physician for interpretation and diagnosis of your blood pressure measurements.
NoTE: Residents outside of the United States (e.g.. Canada and Mexico) should refer
to the WHO Classification Table on page E-11 for assessment of their blood pressure
measurement.

ABOUT BLOOD PRESSURE
ABOUT BLOOD PRESSURE
Assessing High Blood Pressure for Adults
What Is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of the
arteries. Systolic pressure occurs when the heart contracts; diastolic
pressure occurs when the heart expands. Blood pressure is measured in
millimeters of mercury (mmHg).
What Affects Blood Pressure?
Blood pressure is affected by many factors: age, weight, time of day,
activity level, climate, altitude and season. Certain activities can significantly alter one’s blood pressure. Walking can raise systolic pressure by
12 mmHg and diastolic pressure by 5.5 mmHg. Sleeping can decrease
systolic blood pressure by as much as 10 mmHg. Taking your blood
pressure repeatedly without waiting an interval of 5 minutes between
readings, or without raising your arm to allow blood to flow back to the
heart, can also affect it.
The following standards for assessing high blood pressure (without
regard to age or gender) have been established as a guideline. Please note
that other risk factors (e.g. diabetes, obesity, smoking, etc.) need to be
taken into consideration and may affect these figures. Consult with your
physician for an accurate assessment.
JNC7 Classification Table – for adults within the U.S
An individual’s blood pressure varies greatly from day to day and season
to season. For hypersensitive individuals, these variations are even more
pronounced. Normally, blood pressure rises during work or play and falls
to its lowest levels during sleep.

ABOUT BLOOD PRESSURE
ABOUT BLOOD PRESSURE
What Is Hypertension?
Hypertension (high blood pressure) is the diagnosis given when readings
consistently rise above normal. It is well known that hypertension can
lead to stroke, heart attack or other illness if left untreated. Referred to as a
“silent killer” because it does not always produce symptoms that alert you
to the problem, hypertension is treatable when diagnosed early.
Can Hypertension Be Controlled?
In many individuals, hypertension can be controlled by altering lifestyle
and minimizing stress, and by appropriate medication prescribed and
monitored by your doctor. The American Heart Association recommends
the following lifestyle suggestions to prevent or control hypertension:
Don’t smoke.
Have regular
Reduce salt and fat intake. physical checkups.
Maintain proper weight.
Monitor your blood Exercise routinely. pressure at periodic
intervals.
Answers to Why Your Readings are Different Between Home
and at the Doctor’s Office
Why are my readings different between home and at a doctor’s office?
Your blood pressure readings taken in a doctor’s office or hospital setting
may be elevated as a result of apprehension and anxiety. This response is
known as white coat hypertension.
When I bring my monitor to a doctor’s office, why do I get a different
measurement from my monitor to that taken by a doctor or nurse?
The healthcare professional may be using a different sized cuff. The size of
the bladder inside the cuff is critical for the accuracy of the measurement.
This may give you a different reading. A cuff too large will produce
a reading that is lower than the correct blood pressure; a cuff that is
too small will produce a reading that is higher than the correct blood
pressure. There may also be other factors that can cause the difference in
measurements.
Why Measure Blood Pressure at Home?
It is now well known that, for many individuals, blood pressure readings
taken in a doctor’s office or hospital setting might be elevated as a result
of apprehension and anxiety. This response is commonly called “white
coat hypertension.”
In any case, self-measurement at home supplements your doctor’s
readings and provides a more accurate, complete blood pressure history.
In addition, clinical studies have shown that the detection and treatment
of hypertension is improved when patients both consult their physicians
and monitor their own blood pressure at home.

Keys to Successful Monitoring:
Blood pressure fluctuates throughout the day. We recommend that you are
consistent in your daily measurement routine:
• Measure at the same time every day.
• Sit in the same chair/position.
• Do not cross legs and keep your feet flat on the floor.
• Relax for 5 minutes before measurement.
• Use the correct cuff size to get an accurate reading.
• Sit still during measurement – no talking, eating or sudden
movements.
• Record your measurement in a logbook.

ABOUT BLOOD PRESSURE
Establishing Baseline Measurements
The most important method to get an accurate blood pressure
measurement is consistency. To get the most benefit out of your monitor,
it is important to establish a “baseline measurement.” This helps build a
foundation of measurements that you can use to compare against future
readings. To build this baseline measurement, devote two weeks for
consistent blood pressure monitoring. This involves doing everything
the same way when you measure (e.g. measuring during the same time
of day, in the same location, sitting in the same chair, using the same
cuff, etc.). Once you establish your baseline measurement, you can start
evaluating if your measurement has been affected based on things like
lifestyle changes or medication treatment.
How Do I Record My Blood Pressure?
Blood pressure readings are typically recorded with the systolic pressure
written first, followed by a slash mark and the diastolic pressure. For
example, 120 mmHg systolic and 80 mmHg diastolic measurements are
written as 120/80. Pulse is simply written with the letter “P” followed by
the pulse rate—P 72, for example. Please see the back of the manual for
the blood pressure tracking record.
