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 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 device 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.
10
About Memory
The device automatically stores up to ninety blood pressure and pulse
measurements in memory. Data stored in memory are assigned a data number
in the order of the newest to the oldest. The oldest data displays as "n01". The M
symbol in the lower left corner of the display indicates that you are viewing
previous data stored in memory.
Recalling Data
1. When nothing is displayed, press the MEMORY button.
The data number of the most recent measurement and the
data are displayed.
Press
2. If you want to see the previous data, press the
MEMORY button until getting the data you want.
3. The display will shut off automatically one minute after you
press the MEMORY button.
Note: If press the START button when recalling data,
the display shuts off.
Clearing Data
To clear all data stored in memory:
Press and hold the MEMORY button until the
“M”(memory) mark blinks three times.
Remove the batteries and press the START or
the MEMORY button.
Re-install them again.
If there is no stored data in the memory, "--" will appear.

What Is An Irregular Heartbeat
Model UA-782 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
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 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.
13
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.
