Introduction
Thank you for purchasing the OMRON M3 IT Automatic Blood Pressure Monitor.
The OMRON M3 IT is a compact, fully automatic blood pressure monitor, operating
on the oscillometric principle. It measures your blood pressure and pulse rate simply
and quickly. For comfortable controlled inflation without the need of pressure
pre-setting or re-inflation the device uses its advanced “IntelliSense” technology.
Intended Use
This device is a digital monitor intended for use in measuring blood pressure and
pulse rate in adult patient population who can understand this instruction manual
with the arm circumference range printed on the arm cuff. The device detects the
appearance of irregular heartbeats during measurement and gives a warning signal
with the measurement result.
Please read this instruction manual thoroughly before using the device.

Display symbols:
Irregular Heartbeat Symbol ( )
When the monitor detects an irregular
rhythm two or more times during the
measurement, the irregular heartbeat
symbol ( ) will appear on the display
with the measurement values.
An irregular heartbeat rhythm is defined
as a rhythm that is 25% less or 25%
more than the average rhythm detected
while the monitor is measuring the systolic and diastolic blood pressure.
If the irregular heartbeat symbol ( ) displays with your measurement results,
we recommend you consult your physician. Follow the directions of your
physician.
Movement Error Symbol ( )
The movement error symbol is displayed if you move your body during the
measurement. Please remove the arm cuff, and wait 2 - 3 minutes.

Average Value Symbol ( )
The average value symbol is displayed when you press and hold the memory
button for more than 3 seconds. The most recent average value appears on
the display screen.
Cuff Wrap Guide Lamp ( )
If the cuff was wrapped too loosely, it may cause unreliable values. If the
wrapping of cuff is too loose, the cuff wrap guide lamp does not light.
Otherwise
lights in green. This is the function which is used as an aid in
determining if the cuff is wrapped snugly enough.
Blood Pressure Colour Indicator
If your systolic or diastolic pressure is above the
standard range (135 mmHg for the systolic blood
pressure and/or 85 mmHg for the diastolic blood
pressure), the blood pressure colour indicator will light
in orange when the measurement result is displayed.
If they are within the standard range, no light will
appear.
The JNC7* Guideline recommends the following guideline.
These are form statistical values for blood pressure.
