Automatic Blood
Pressure Monitor
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.

Important Safety Information
Caution: Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury to the user or patient or
damage to the equipment or other property.
(General Usage)
Always consult your physician. Self-diagnosis of measurement results and
self-treatment are dangerous.
People with severe blood flow problems, or blood disorders, should consult a
physician before using the device, as the arm cuff inflation can cause bruising.
If there are any abnormalities during the measurement, remove the arm cuff.
Do not use this device on infants or persons who cannot express their intentions.
Do not inflate the arm cuff more than necessary.
Do not use the device for any purpose other than measuring blood pressure.
Use only the approved arm cuff for this device. Use of other arm cuffs may result
in incorrect measurement results.
Do not use a mobile phone or other devices that emit electromagnetic fields,
near the device. This may result in incorrect operation of the device.
Do not disassemble the monitor or arm cuff.
Do not use in a location with moisture, or a location where water may splash on
the device. This may damage the device.
Do not use the device in a moving vehicle (car, airplane).
Do not take measurements more than necessary. It may cause bruising due to
blood flow interference.
Consult your physician before using the device if you had a mastectomy.
(AC Adapter (optional) Usage)
Fully insert the power plug into the outlet.
When disconnecting the power plug from the outlet, do not pull the power cord.
Be sure to pull from the power plug safely.
When handling the power cord, take care not to do the following:
Do not damage.
Do not break it.
Do not tamper with it. Do not forcibly bend or pull.
Do not twist.
Do not bundle during use.
Do not pinch.
Do not place under heavy objects.
Wipe the dust off from the power plug.
Unplug monitor when not in use.
Disconnect the power plug before cleaning.
Use only the original adapter designed for this device. Use of unsupported
adapters may damage and/or may be hazardous to the device.
(Battery Usage)
Do not insert the batteries with their polarities incorrectly aligned.
Use only 4 “AA” alkaline or manganese batteries with this device. Do not use
other types of batteries. Do not use new and used batteries together.
Remove the batteries if the device will not be used for three months or more.
General Precautions
• Do not forcibly crease the arm cuff or the air tube excessively.
• Do not press the air tube while taking a measurement.
• To unplug the air plug, pull on the air plug at the connection with the monitor, not
the tube itself.
• Do not drop the monitor or subject device to strong shocks or vibrations.
• Do not inflate the arm cuff when it is not wrapped around your arm.
• Do not use the device outside the specified environment. It may cause an
inaccurate result.
• Read and follow the "Important information regarding Electro Magnetic
Compatibility (EMC)" in the "6. Specifications".
• Read and follow the "Correct Disposal of This Product" in "6. Specifications" when
disposing of the device and any used accessories or optional parts.

• When you take a measurement on the right
arm, the air tube will be at the side of your
elbow. Be careful not to rest your arm on the
air tube.
• The blood pressure can differ between the right arm and the left arm, and
therefore also the measured blood pressure values can be different.
OMRON recommends to always use the same arm for measurement. If the
values between both arms differ substantially, please check with your
physician which arm to use for your measurement.
