How UA-789 Works
LifeSource®blood pressure monitors are easy to use, accurate and
digitally display full measurement readouts. Our technology is based on
the “oscillometric method” – a noninvasive blood pressure determination.
The term “oscillation” refers to any measure of vibrations caused by the
arterial pulse. Our monitor examines the pulsatile pressure generated by
the arterial wall as it expands and contracts against the cuff with each
heartbeat. The cuff is inated until the artery is fully blocked. The ination
speed is maximized and the pressure level is optimized by the device. The
monitor takes measurements while the cuff is both inating and deating.
This results in a faster measurement providing greater comfort to the user.
Before You Start
You must install 4 type AA (1.5 volt) batteries (alkaline batteries
recommended), or use the AC Adapter (see page E-14 for using the
Monitor with AC Adapter) and attach the cuff to the monitor before using
it. To install batteries (or replace them if the “Low Battery” symbol appears
on display), proceed as follows:
1. Remove battery compartment cover by
gently pushing down on arrow and sliding
cover forward.
2. Put in bottom row of batteries rst. Place
the batteries in compartment with positive
(+) and negative (–) terminals matching
those indicated in the compartment.
Be sure batteries make contact with
compartment terminals.
3. Replace cover by sliding it into the
compartment and gently pressing into place.
NOTE: Rechargeable batteries will not work with this monitor

E-5
Selecting the Correct Cuff Size
Using the correct cuff size is important for an accurate reading. A cuff
that is 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. With your arm hanging at the side of
your body, measure the circumference of your upper arm at the midpoint
between the shoulder and elbow.

Taking Your Blood Pressure
Now you are ready. Follow these simple steps:
1. Sit comfortably with your left arm resting on a at surface so that the
center of your upper arm is at the same height as your heart.
2. Lay left arm on the table with palm up.
Place the cuff on your upper arm. Align the
yellow Brachial Artery Marker on the cuff
over the brachial artery on the inside of the
arm. The tube should be facing downward
and toward the inside of your arm. Fasten
the cuff securely. The bottom of the cuff
should be about 1” above your elbow.
3. The cuff should be snug but not too tight.
You should be able to insert two ngers
between the cuff and your arm.
NOTE: If you have difculty placing the cuff on by yourself,
please have somebody close by who can assist you.
4. Press the START button. Your average
blood pressure reading will appear

What is an Irregular Heartbeat
The UA-789 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 dened 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.
About Cuff Ination Meter
The Cuff Ination Meter is located on the left side of the display screen to
tell you when the blood pressure monitor is inating and deating the cuff.
The Cuff Ination Meter moves up during ination and moves down during
deation.

About Average Reading
The UA-789 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 ash several times before the cuff begins
to inate. The average blood pressure reading
will also appear briey when you recall the
measurements stored in memory.
About Pressure Rating indicator™
The Pressure Rating Indicator™is a feature which
provides a snapshot of your blood pressure
classication 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 classication, please refer to “Assessing
High Blood Pressure” on page E-16.
: The indicator displays a segment, based on the current measurement,
corresponding to the JNC7 Classication.
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
Classication Table on page E-16 for assessment of their blood pressure measurement.

About Blood Pressure
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
signicantly 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 ow back
to the heart, can also affect it.
In addition to these factors, beverages containing caffeine or alcohol,
certain medications, emotional stress and even tight-tting clothes can
make a difference in the readings.
What Causes Variations In Blood Pressure?
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.
Fluctuation within a day (case: 35 year old male)

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:
qDon’t smoke.
qReduce salt and fat intake.
qMaintain proper weight.
qExercise routinely.
qHave regular physical checkups
qMonitor your blood pressure at periodic intervals.
Why Measure Blood Pressure at Home?
It is now well known that, for many individuals, blood pressure readings
taken in a doctor’s ofce 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.

About Blood Pressure
Answers to Why Your Readings Are Different Between Home
and at the Doctor’s Ofce
Why are my readings different between home and at a doctor’s
ofce?
Your blood pressure readings taken in a doctor’s ofce 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 ofce, 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.
Keys to Successful Monitoring:
Blood pressure uctuates throughout the day. We recommend that you
are consistent in your daily measurement routine:
qMeasure at the same time every day.
qSit in the same chair/position.
qDo not cross legs and keep your feet at on the oor.
qRelax for 5 minutes before measurement.
qUse the correct cuff size to get an accurate reading.
qSit still during measurement – no talking, eating or sudden movements.
qRecord your measurement in a logbook.
