Using The Monitor
Selecting The Correct Cuff
Using the correct cuff size is important for an accurate reading. If the cuff is not
the proper size, the reading may yield an incorrect blood pressure value.
The arm size is printed on each cuff.
The index and proper fit range, on the cuff, tell you if you are attaching the
correct cuff. (Refer to "Attaching The Arm Cuff" below)
If the index points outside of the range, contact your local dealer to purchase a
replacement cuff.
Arm Size Recommended Cuff Size Order No.
32 cm to 45 cm Large cuff UA-CUFDBKLA-EC
22 cm to 32 cm Medium cuff UA-CUFDBKAU-EC
－Small cuff －
Arm size: The circumference at the biceps.
Note: This UA-851 monitor is NOT designed for using a small cuff.
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.
Measurement
During measurement, it is normal for the cuff to feel very tight. (Do not be
alarmed).
After Measurement
After measurement, press the START button to turn off the power. Remove
the cuff.

Measurements
Model UA-851 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.
Normal Measurement
1. Place the cuff on the arm (preferably the left arm).
Sit quietly during measurement.
2. Press the START button.
All of the display segments are displayed.
Then, 0 (zero) is displayed blinking briefly.
Then the display changes, as indicated in
the figure at the right, 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, as in
the figure at the right, during inflation.
Note: If you wish to stop inflation at any time,
press the START button again.
3. When inflation is complete, deflation starts
automatically and (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. The cuff exhausts
the remaining air and deflates completely.
5. Press the START button again to turn off
the power.
Note: The device has an automatic power shut-off function, which turns the
power off automatically one minute after measurement.
Allow at least ten 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 button.
Release the button when the average
of all the data in memory is displayed.
Press and hold the START button
again until a number about 30 to 40
mmHg higher than your expected
systolic pressure appears.
3. Release the START 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.
An individual's 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 for the
description of the symbols.
This blood pressure monitor 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
The device 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 be relaxed,
remain still and do not talk during measurements.
Note: We recommend contacting your physician if you see this
indicator frequently.
Pressure Bar Indicator
The indicator monitors the progress of pressure during 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). 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 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.
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
individuals, 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

English 14
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.
