Introduction
Thank you for purchasing the OMRON IW2 Automatic Wrist Blood Pressure
Monitor.
This remarkable, compact and easy to use instrument is ideal for people who
frequently monitor their own blood pressure. The small, pre-formed wrist cuff
is very convenient and easy to apply.
With the push of a button the OMRON Wrist Blood Pressure Monitor
measures your blood pressure and pulse and displays the reading on a clear
digital panel. Perfect for quick, easy readings at home, at work, and while
traveling. It also stores up to 90 sets of measurements in memory and displays
an average reading based on the three most recent measurements.
The OMRON Wrist Monitor uses the oscillometric method of blood pressure
measurement. This means the monitor detects the pulse wave vibrations in the
artery of your wrist and converts the oscillations into a digital reading.
Clinical research has proven a direct relationship between blood pressure in
the wrist and blood pressure in the arm. Changes in wrist blood pressure
reflect changes in arm blood pressure because the arteries in the wrist and the
arm are connected.
Frequently measuring the blood pressure in your wrist will provide you and
your doctor with an accurate indication of changes in your true blood
pressure.
Please read this instruction manual thoroughly before using
the unit. For specific information about your own blood
pressure, consult your doctor.

Notes on Safety
The OMRON IW2 is not suitable for measuring the frequency of cardiac
pacemakers.
You should never change the dosage of medication prescribed by your doctor.
People with poor peripheral circulation may find that results for measurements
taken at the wrist vary from those taken on the upper arm.
Use the OMRON IW2 only for yourself.
Caution
Self-diagnosis of measured results and treatment are dangerous. Please follow
the instructions of your doctor.
Do not use the unit on infants or persons who cannot express their consent.
Do not use the unit for any purpose other than measuring blood pressure.
Do not use a cellular phone, or other devices that emit electromagnetic fields,
near the unit. This may result in incorrect operation of the unit.

Initial Set-Up
How to Set the Date and Time
Your blood pressure monitor automatically stores up to 90 measurement values
in its memory and calculates an average value based on the last three
measurements. To make use of the memory and average value function:
• Set the monitor to the correct date and time before taking a measurement
for the first time.
• If the batteries have been removed for a long period of time, the date and
time setting will need to be reset.
1. When the batteries are installed for the first time,
the year digits (2004) will flash on the display
when you turn on the monitor.
Note:
* The range for the year setting is 2004 to 2030.
If the year reaches 2030, it will return to 2004.
* If you need to reset the date and time, press the SET button until the
setting you want to adjust appears on the display, then press the MEM

irregular heartbeat function 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 notify your doctor.
Note:
* Do not use this monitor to measure blood pressure for more than one
person since the measurement values are automatically stored in
memory and an average value based on the last three measurements is
calculated.

What is Irregular Heartbeat?
An irregular heartbeat is a heartbeat
rhythm that varies by more or less
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 notify your
doctor. Conducting self-diagnosis and treatment based on measurement results
is dangerous. Be sure to follow the instructions of your doctor.
