Thank you for purchasing the IA2 Omron Automatic Blood Pressure
Monitor with IntelliSenseTM. Although your blood pressure fluctuates
throughout the day, no self adjustment is necessary as the monitor
intelligently adjusts to your changing conditions. The IntelliSense
monitor uses fuzzy logic intelligence to sense both your systolic and
diastolic blood pressure values, and the result is personalized inflation
for every reading. This virtually eliminates discomfort or incorrect
readings due to improper cuff inflation.

The IA2 also stores up to 90 sets of measurements in memory and
displays an average reading based on the three most recent
measurements..

Please read this instruction manual thoroughly before using the unit. For
specific information about your own blood pressure, consult your doctor.

easily, so you can pull the cuff off and on.

• Make sure that there are no kinks in the air tubing.

Taking measurements on the right arm

Please note the following points when
applying the cuff to your right arm.
Apply the cuff so that the air tube is at
the side of your elbow.

Notes:

• Be careful not to rest your arm on the air tube, otherwise it will

restrict the flow of air to the cuff.

• Apply the arm cuff so that no part of the cuff is positioned over the

elbow joint. The cuff should be 1 - 2 cm above the elbow.

How to Take a Measurement

1. Press the START/STOP button and remain still, the cuff will start to
inflate automatically.

As the cuff begins to inflate, the monitor automatically determines
your ideal inflation level. Because this monitor detects the pulse
even during inflation, do not move your arm and remain still until
the entire measurement process has been completed.

Note:

Do not inflate the cuff if it is not wrapped around your arm.

2. Inflation stops automatically and measurement is started.

As the cuff slowly deflates, decreasing numbers appear on the

display and the Heartbeat Symbol ( ) flashes at every heartbeat.

In rare circumstances, a higher inflation may be necessary. In these
cases, the monitor automatically reinflates the cuff up to 40 mmHg
higher than the initial inflation and restarts the measurement.

Correct Usage

3. When the measurement is complete, the arm
cuff completely deflates and your blood
pressure and pulse rate are displayed.

Note:

The monitor automatically stores blood
pressure and pulse rate into its memory.

4. Press the START/STOP button to
turn the monitor off.

Note:

If you forget to turn the monitor off,
it will automatically shut itself off
after five minutes.

Important:

• Wait 2-3 minutes before taking another blood pressure

measurement. Waiting between readings allows the arteries to
return to the condition prior to taking the blood pressure
measurement.

• If you move during measurement, the movement error symbol

( ) may appear. Repeat the measurement and remain still
until the measurement is complete.

• Your blood pressure monitor includes an irregular heartbeat
feature. Irregular heartbeats can influence the results of the
measurement. The irregular heartbeat feature automatically
determines if the measurement is usable or needs to be
repeated. If the measurement results are affected by irregular
heartbeats but the result is valid, the result is shown together
with the irregular heartbeat symbol ( ). If the irregular
heartbeats cause the measurement to be invalid, no result is
shown. If the irregular heartbeat symbol ( ) is shown after
you have taken a measurement, repeat the measurement. If the
irregular heartbeat symbol ( ) is shown frequently, please let
your doctor be aware of it.

Instructions for special conditions

If your systolic pressure is known to be more than 220 mmHg, press and
hold the START/STOP button until the monitor inflates 30 to 40 mmHg
higher than your suspected systolic pressure.

Notes:

• The monitor will not inflate above 299 mmHg.

• Do not apply more pressure than necessary.

What is Irregular Heartbeat?

An irregular heartbeat is a
heartbeat rhythm that varies by
more than 25% from the average
heartbeat rhythm detected while
the unit is measuring the systolic
and diastolic blood pressure.
If such an irregular rhythm is
detected more than twice during
measurement, the irregular
heartbeat symbol ( ) appears on the display when the measurement
results are displayed.

What is Arrhythmia?

A heartbeat is stimulated by electrical signals that cause the heart to
contract.
Arrhythmia is a condition where the heartbeat rhythm is abnormal due
to flaws in the bio-electrical system that drives the heartbeat. Typical
symptoms are skipped heartbeats, premature contraction, an abnormally
rapid (tachycardia) or slow (bradycardia) pulse. This can be caused by
heart disease, aging, physical predisposition, stress, lack of sleep, fatigue
etc. Arrhythmia can only be diagnosed by a doctor through a special
examination.
Whether the appearance of the irregular heartbeat symbol ( ) in the
results indicates arrhythmia or not can only be determined by an
examination and diagnosis by your doctor.
If the irregular heartbeat symbol ( ) is shown frequently, please let
your doctor be aware of it. Self-diagnosis and treatment based on
measurement results is dangerous. Be sure to follow the instructions of
your doctor.

How to Use the Memory Function

This monitor has a memory capable of storing 90 sets of readings. Every
time you complete the measurement, the monitor automatically stores
the blood pressure and pulse rate. The monitor also calculates an
average reading based on the measurements from the last three readings.

To ensure that the measurement results are recorded correctly, make sure
that the date and time are set correctly before taking a measurement.
When 90 sets of readings are stored in memory, the oldest set will be
deleted to store a new set.
The date and time of stored readings will be alternately displayed.

To View the Average Value

Press the MEMORY button.

The average values based on the three most recent measurements is
