INTRODUCTION

Thank you for purchasing the OMRON® BP742N Blood Pressure Monitor.
Your new blood pressure monitor uses the oscillometric method of blood

essure measurement. This means the monitor detects your blood movement

pr
through your brachial artery and converts the movements into a digital reading.
An oscillometric monitor does not need a stethoscope so the monitor is simple
to use.

Intended Use

This device is a digital monitor intended for use in measuring blo
and pulse rate in adult patient population. The device detects the appearance of
irregular heartbeats during measurement and gives a warning signal with the
measurement result.

Please read this instruction manual thor

Please keep for future reference. For specific information about your own
blood pressure, CONSULT YOUR PHYSICIAN.

(General Usage)

DO NOT adjust medication based on measurement
pressure monitor. Take medication as prescribed by your physician. Only a
physician is qualified to diagnose and treat High Blood Pressure.

This device is not intended to be a diagnostic device.
Consult your physician before using the device for any of the following

conditions: common arrhythmias such as atrial or ventricular premature
beats or atrial fibrillation, arterial sclerosis, poor perfusion, diabetes, age,
pregnancy, pre-eclampsia, renal diseases.
Note that PATIENT motion, trembling, shivering may affect the measurement
reading.

Do not use the device on the injured arm or the arm under medical
treatment.

Do not apply the arm cuff on the arm while being on an intravenous drip or
blood transfusion.

Consult your physician before using the device on the arm with an arterio­venous (A-V) shunt.

Do not use the device with other medical electrical (ME) equipment
simultaneously.

Do not use the device in the area the HF surgical equipment, MRI, or CT
scanner exists, or in the oxygen rich environment.

(General Usage)

Always consult your physician. Self-diagnosis of
self-treatment are dangerous.

Consult your physician before using the device for any of the following
conditions:

• If you have had a mastectomy.

• Do not take measurements more than necessary. It may cause bruising

• People with severe blood flow problems or blood disorders as cuff inflation

Remove the arm cuff if it does not start deflating during the measurement.
Do not use this device on infants or persons who cannot express their

intentions.
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. This may cause an inaccurate

reading.
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).
Read “If your systolic pressure is more than 210 mmHg” of this instruction

manual, if your systolic pressure is known to be more than 210 mmHg.
Inflating to a higher pressure than necessary may result in bruising where

With the increased number of electronic devices such as PC’s and mobile (cellular)
telephones, medical devices in use may be susceptible to electromagnetic interference
from other devices. Electromagnetic interference may result in incorrect operation of the
medical device and create a potentially unsafe situation. Medical devices should also not
interfere with other devices.

In order to regulate the requirements for EMC (Electro Magnetic Compatibility) with the

im to prevent unsafe product situations, the IEC60601-1-2 standard has been

implemented. This standard defines the levels of immunity to electromagnetic
interferences as well as maximum levels of electromagnetic emissions for medical
devices.

Medical devices manufactured by OMRON Healthcare conform to this IEC60601-1-2:2007

andard for both immunity and emissions.

Field strengths from fixed transmitters, such as base stations for radio (cellular/ cordless) telephones

and land mobile radio, AM and FM radio broadcast, and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters,
an electromagnetic site survey should be considered. If the measured field strength in the location in
which the OMRON BP742N including AC-adapter is used exceeds the applicable RF compliance
level above, the OMRON BP742N including AC-adapter should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the OMRON BP742N including AC-adapter.

GUIDANCE AND MANUFACTURER’S DECLARATION

Recommended separation distance between portable and mobile RF communications

OMRON BP742N including AC-adapter is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of this OMRON BP742N
including AC-adapter can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
OMRON BP742N including AC-adapter as recommended below, according to the maximum
output power of the communications equipment.

Output Power of Transmitter

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) according
to the transmitter manufacturer.
Note: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
