Measurements
The UA-1020 is designed to detect the pulse and to inflate the cuff to a
systolic pressure level automatically.
If re-inflation occurs repeatedly, use the following methods.
Measurement with the SET Pressure
During the blood pressure measurement, re-inflation may occur.
A fixed pressure value can be set to avoid re-inflation.
1. At step 6 of the clock adjustment procedure
(refer to page 10), press the SET button to
go to the pressure setting mode. The current
setting blinks.
2. Press the or button to select a pressure
value about 30 mmHg or more above your
expected systolic pressure from the following.
AUTO : Automatic pressurization (default value)
180 : Pressure value of 180 mmHg (fixed)
210 : Pressure value of 210 mmHg (fixed)
240 : Pressure value of 240 mmHg (fixed)
3. Press the
SET button to go to the TriCheckTM setting mode.
Press the START button to turn the device off. After three minutes of
non-operation, the device will turn off automatically.
The next measurement will be performed with the new pressure value.
Measurement with the Desired Systolic Pressure
Use this method when re-inflation occurs repeatedly even if the pressure
value is set to 240 in the procedure above or when the results are not
displayed even if the pressure decreases to 20 mmHg or less.
1. Place the cuff on the arm (preferably the left arm).
2. Press and hold the START button
until a number about 30 to 40 mmHg
higher than your expected systolic
pressure appears.
3. When the desired number is reached,
release the START button to start
measurement. Continue to measure
your blood pressure as described on
the previous page.

Notes for Accurate Measurement
Sit down in a comfortable position. Place your arm on a table with your
palm facing upward and the cuff at the same level as your heart.
Relax for about five to 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 6 for the
description of symbols.
This device is intended for use by adults. Consult with your physician
before using this device on a child. A child should not use this device
unattended.
The automatic blood pressure monitor's performance may be affected by
excessive temperature or humidity, or altitude.

What Is The IHB/AFib Indicator?
When the monitor detects an irregular rhythm during the measurements,
the IHB/AFib indicator will appear on the display with the measurement
values.
Note: We recommend contacting your physician if you see this
IHB/AFib indicator frequently.
What Is The AFib?
The heart contracts due to electrical signals occurring in heart and sends
blood through the body. Atrial fibrillation (AFib) occurs when the electrical
signal in the atrium becomes confused and leads to disturbances in the
pulse interval. AFib can cause blood to stagnate in the heart, which can
easily create clots of blood, a cause of stroke and heart attack.
Pressure Bar Indicator
The indicator monitors the progress of pressure during measurement.
WHO Classification Indicator
Each segment of the bar indicator
corresponds to the WHO blood pressure
classification described on the next page.
