Using the Monitor
6. 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.
7. 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 twenty or
thirty minutes before taking the measurement.
Try to measure your blood pressure at the same time every day.
8. Measurement
During measurement, it is normal for the cuff to feel very tight. (Do not be
9. After measurement
After measurement, press the START button to turn off the power. Remove
the cuff and record your data.
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
Model UA-787 is designed to detect the pulse and to inflate the cuff to
systolic pressure level automatically.
If your systolic pressure is expected to exceed 230 mmHg or you use the
optional small cuff, read "Measurement with the desired systolic pressure"
on 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 display symbols appear 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.
Note: If you wish to stop inflation at any time, press
the 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 flashes with
each pulse beat.
Note: If an appropriate pressure is not obtained,
the device starts to inflate again
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 is provided with an automatic power shut-off function.
Allow at least ten minutes between measurements on the same
Measurement with the desired systolic pressure
If your systolic pressure is expected to exceed 230 mmHg or you use the optional
small cuff, use this procedure.
1. Place the cuff on the arm (preferably the left
2. Press and hold the START button until a
number about 30 to 40 mmHg higher than your
expected systolic pressure appears.
3. Release the START button, when the desired
number is reached, measurement will begin.
Then continue to measure your blood pressure
as described on page 7.
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 heart beat. If you have a very
weak or irregular heart beat, 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. See the section on the
descriptions of display symbols for details.
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.
Recalling Memory Data
Note: This device stores the last thirty measurements in memory
automatically. The data is retained as long as the batteries
are in the device. When you remove the batteries or the
batteries are drained, the data will be erased.
1. When nothing is displayed, press the MEMORY button.
2. The date and the newest data are displayed.
3. When the MEMORY button is pressed while data is
displayed, the previous data is displayed.
4. Each time the MEMORY button is pressed, the
memorized data is displayed. After the last data is
displayed, the display goes blank.
5. Press and hold the MEMORY button until the “
for clearing the stored data.
” (memory) mark flashes
Note: Pressing the START button while the memory data is displayed
initiates the UA-787 to start taking a measurement.
About Blood Pressure
1. 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.
2. 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
3. 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.
4. WHO blood pressure classification
Standards for assessment of
high blood pressure, without
regard to age, have been
established by the World
Health Organization (WHO),
as shown in the chart below.
5. 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
described in this manual, and know your normal blood pressure. Many
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.

Remove the batteries. Place
them back properly and try

If the actions described above do not solve the problem, contact the
dealer. Do not attempt to repair the device yourself.
Do not open the device. It uses delicate electrical components and an
intricate air unit that could be damaged. If you can not fix the problem
using the troubleshooting instructions, request service from your supplier
or from the A&D service group. The A&D service group will provide
technical information, spare parts and units to authorized suppliers.
The technical testing procedures, which should be done at least every 2
years, can be performed either by the manufacturer or by an authorized
repair service in accordance with the regulations governing manufacturing
of medical products.
