Introduction
Thank you for purchasing the Omron HEM-637 Wrist Blood Pressure Monitor
with Advanced Positioning Sensor (APS). This remarkable instrument is ideal
for people who frequently monitor their own blood pressure because it’s so
compact and easy to use. There is no tricky arm cuff, just a small, pre-formed
wrist cuff that is easy to apply. With the push of a button the Omron Wrist
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.
The Omron Wrist Monitor uses the oscillometric method of blood pressure
measurement. This means the monitor detects your blood’s movement through
the artery in your wrist and converts the movements into a digital reading.
An oscillometric monitor does not need a stethoscope so the monitor is simple
to use and measurements are easy to obtain.
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 connect. 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
operating the Omron Wrist Blood Pressure Monitor with
Advanced Positioning Sensor (APS) to assure proper use.
For specific information on your own blood pressure,
CONTACT YOUR PHYSICIAN.

Two AAA Alkaline

Carrying Case
Blood pressure changes throughout the day. IntelliSense technology was developed
by Omron which enables your blood pressure monitor to inflate and deflate at the
optimum level for each individual. This helps ensure accurate measurement,
and is particularly useful for people with certain arrythmia or heart disorders.
Correct cuff positioning is critical when monitoring blood pressure. The Omron
Wrist (APS) Blood Pressure Monitor has a unique positioning sensor that
confirms the cuff is level with the user’s heart. This helps ensure that each
reading is accurate and reliable.

Suggestions Before Measuring
Blood Pressure
1. Avoid eating, smoking and exercising for at least
30 minutes before taking measurement. Also rest
for at least 10 to 15 minutes before taking a reading.
2. Stress raises blood pressure. Avoid taking
measurements during stressful times.
3. The cuff can be applied to your left
or right wrist.
4. Measurements should be taken in a quiet place
and you should be in a relaxed, seated position.
5. Remain still and do not talk during
the measurements.
6. Keep a record of you blood pressure and pulse for you doctor.
Remember, a single measurement does not provide an accurate indication
of your true blood pressure. You need to take and record several readings
over a period of time. Try to measure your blood pressure at the same
time each day for consistency.
7. Wait 2-3 minutes between measurements. Waiting allows the engorged blood
vessels to return to normal. You may require more rest time between readings
depending on your individual physiological characteristics.

Battery Replacement
• High performance alkaline dry cell batteries (2 “AAA”) should be good
for approximately 300 readings.
• Battery life varies with ambient temperature. Battery life is shorter under
cold conditions such as during the winter.
• If the battery replacement symbol blinks while measuring or if pressure
is not applied when the START / STOP button is pressed, replace both
batteries (use the same brand).
• Holding the START / STOP button down may shorten battery life. To avoid
pressure on the button when transporting or storing, use the case provided.
• If the batteries have been replaced or removed, resetting of the date and
time is required.
• If you are not going to use this monitor for a long period of time (approximately
three months or more), remove the batteries.
• Do not use batteries not specified for this unit, worn and new batteries
together, or different brands of batteries together.
