Introduction
Thank you for purchasing the Omron IW1 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 IW1 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 IW1 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.
Battery liquid may leak and damage the main unit. Please observe the
following points.
• When you are not going to use the unit for a long period of time
(approximately three months or more), take out the batteries.
• Replace old batteries with new ones immediately.
• Do not use old and new batteries together.
• Do not insert the batteries with their polarities incorrectly aligned.

Suggestions for Measuring Blood Pressure
Avoid eating, drinking, smoking, or exercising for at least 30 minutes before
taking a measurement. You should also try to measure your blood pressure at
the same time each day.
Measurement should be taken in a quiet place and you should be in a
relaxed, seated position.
1. Align the wrist cuff with the level of your heart
and gently support your left arm with your right
hand. Do not place your right hand on the cuff
itself.
2. Press the START/STOP button.
Remain still and do not talk during the
measurement.
Notes:
* Always wait at least 2-3 minutes before taking another blood pressure
measurement.
You may require more rest time between readings depending on your
individual physiological characteristics.
* Only use the IW1 to measure your own blood pressure since the results
of measurements are stored in memory.
* Always wrap the wrist cuff around your wrist before starting to take a
measurement.
* Do not measure your blood pressure while you are in a vehicle.
* Always measure your blood pressure on the same wrist.
