INTRODUCTION
Thank you for purchasing the OMRON® BP742N Blood Pressure Monitor.
Your new blood pressure monitor uses the oscillometric method of blood
pressure measurement. This means the monitor detects your blood movement
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 blood pressure
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.

KNOW YOUR DEVICE
Before Taking a Measurement
To help ensure an accurate reading, follow these directions:
1. Avoid bathing, drinking alcohol or caffeine, smoking, exercising and eating for
30 minutes before taking a measurement. Rest for at least 15 minutes before
taking the measurement.
2. Stress raises blood pressure. Avoid taking measurements during stressful
times.
3. Measurements should be taken in a quiet place.
4. Remove tight-fitting clothing from your arm.
5. Sit on a chair with your feet flat on the floor. Rest your arm on a table so that
the arm cuff is at the same level as your heart.
6. Remain still and do not talk during the measurement.
7. Keep a record of your blood pressure and pulse readings for your physician.
A single measurement does not provide an accurate indication of your true

a
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.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

GUIDANCE AND MANUFACTURER’S DECLARATION
