Using The Monitor
Attaching The Arm Cuff
1. Wrap the cuff around the upper arm, about
2 - 3 cm above the elbow, as shown.
Place the cuff directly against the skin,
as clothing may cause a faint pulse
and result in a measurement error.
2. Constriction of the upper arm, caused
by rolling up a shirtsleeve, may prevent
accurate readings.
3. Confirm that the index points within
the proper fit range.
How To Take Proper Measurements
For the most accurate blood pressure
measurement:
Sit comfortably at a table.
Rest your arm on the table.
Relax for about five to ten minutes
before measurement.
Place the center of the cuff at the same height as your heart.
Remain still and keep quiet during measurement.
Do not measure right after physical exercise or a bath. Rest for twenty or
thirty minutes before taking the measurement.
Try to measure your blood pressure at the same time every day.

Measurements
Model UA-774 is designed to detect the pulse and to inflate the cuff to a
systolic pressure level automatically.
If your systolic pressure is expected to exceed 230 mmHg, read " Measurement
with the desired systolic pressure
" on the next page.
Model UA-774 can store the last thirty sets of data for each button. We
recommend that if two people regularly use the device, one uses the
START 1
button and the other uses START 2 button, to prevent confusion over stored data.
Normal Measurement With Storing Data
1. Place the cuff on the arm (preferably the left arm).
Sit quietly during measurement.
2. Press the START 1 (or START 2 ) button.
The average blood pressures and last data
number are displayed briefly. Then current
pressure is displayed, as the measurement
begins. The cuff starts to inflate. It is normal
for the cuff to feel very tight. A pressure bar
indicator is displayed during measurement.
Note: If you wish to stop inflation at any time,
press either START button again.
3. When inflation is complete, deflation starts
automatically and the (heart mark) blinks,
indicating that the measurement is in
progress. Once the pulse is detected, the
mark blinks with each pulse beat.
Note: If an appropriate pressure is not
obtained, the device starts to inflate
again automatically.
4. When the measurement is complete, the
systolic and diastolic pressure readings
and pulse rate are displayed and stored.
The cuff exhausts the remaining air and
deflates completely.
5. Press either START button again to turn
off the power.
Note: Model UA-774 is provided with an automatic power shut-off function.
Allow at least three minutes between measurements on the same person.

Measurements
Measurement With The Desired Systolic Pressure
If your systolic pressure is expected to exceed 230 mmHg, use this
procedure.
1. Place the cuff on the arm
(preferably the left arm).
2. Press and hold the START 1 (or START 2)
button to display the last data number.
3. Press and hold the START 1 (or START 2)
button again until a number about 30 to 40
mmHg higher than your expected systolic
pressure appears.
4. Release the START 1 (or START 2) button
to start measurement, when the desired
number is reached. Then continue to
measure your blood pressure as
described on the previous page.
Notes For Proper Measurement
Sit down in a comfortable position. Place the arm to be used for the
measurement on a table or other support so that the center of the cuff will be
at the same height as your heart.
Relax for about five or ten minutes before taking a measurement. If you are
excited or depressed by emotional stress, the measurement will reflect this
stress as a higher (or lower) than normal blood pressure reading and the
pulse reading will usually be faster than normal.
Your blood pressure varies constantly, depending on what you are doing and
what you have eaten. What you drink can have a very strong and rapid effect
on your blood pressure.
This device bases its measurements on the heartbeat. If you have a very
weak or irregular heartbeat, the device may have difficulty determining your
blood pressure.
Should the device detect a condition that is abnormal, it will stop the
measurement and display an error symbol. Refer to page 4.
Model UA-774 is intended for use by adults only. Consult with your physician
before using this device on a child. A child should not use this device
unattended.

What Is An Irregular Heartbeat?
Model UA-774 blood pressure monitor provides a blood pressure and pulse
rate measurement even when an irregular heartbeat occurs. An irregular
heartbeat is defined as a heartbeat that varies by 25% from the average of all
heartbeats during the blood pressure measurement. It is important that you are
relaxed, remain still and do not talk during measurements.
Note: We recommend contacting your physician if you see this indicator frequently.
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). One's natural blood pressure is represented by the fundamental
pressure, which is measured first thing in the morning while one is still at rest
and before eating.
What Is Hypertension And How Is It Controlled?
Hypertension, an abnormally high arterial blood pressure, if left unattended, can
cause many health problems including stroke and heart attack. Hypertension
can be controlled by altering lifestyle, avoiding stress, and with medication under
a doctor’s supervision. To prevent hypertension or to keep it under control:
Do not smoke Exercise regularly
Reduce salt and fat intake Have regular physical checkups
Maintain proper weight
Why Measure Blood Pressure At Home?
Blood pressure measured at a clinic or doctor's office may cause apprehension
and can produce an elevated reading, 25 to 30 mmHg higher than that
measured at home. Home measurement reduces the effects of outside
influences on blood pressure readings, supplements the doctor's readings and
provides a more accurate, complete blood pressure history.
WHO Blood Pressure
Classification
Standards to assess high blood
pressure, without regard to age,
have been established by the
World Health Organization
(WHO), as shown in the chart
at the right.

English 11
Blood Pressure Variations
An individual’s blood pressure varies greatly on a daily and seasonal basis. It
may vary by 30 to 50 mmHg due to various conditions during the day. In
hypertensive individual variations are even more pronounced. Normally, the
blood pressure rises while at work or play and falls to its lowest levels during
sleep. So, do not be overly concerned
by the results of one measurement.
Take measurements at the same time
every day using the procedure
described in this manual to get to
know your normal blood pressure.
Regular readings give a more
comprehensive blood pressure history.
Be sure to note date and time when
recording your blood pressure.
Consult your doctor to interpret your
blood pressure data.
