INTRODUCTION
Thank you for purchasing the ReliOn HEM-412CREL Manual Inflation
Blood Pressure Monitor.
Fill-in for future reference
DATE PURCHASED: ______________
SERIAL NUMBER: ________________
Staple your purchase receipt here.
The monitor features an easy-to-squeeze inflation bulb that allows
you to quickly inflate the cuff. The measurement reading is clearly
displayed on a large digital panel.
Omron digital blood pressure monitors use the oscillometric method
of blood pressure measurement. This means the monitor detects
your blood’s 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.
The ReliOn HEM-412CREL Manual Inflation Blood Pressure Monitor
is intended for home use.

QUICK REFERENCE GUIDE
1. Avoid eating, smoking, and exercising for at least 30 minutes before
taking a measurement.
2. Put your left arm through the cuff loop. The bottom of the cuff
should be about 1/2 inch above the elbow. The cuff tab should lie
over the brachial artery on the inside of the arm.
3. Pull the cuff so that it is tightened evenly around your arm. Insert one
finger under cuff to check fit. Press the sewn hook material firmly
against the pile side of the cuff. Make sure that your skin will not be
pinched in the D-ring once you inflate the cuff. Immediately deflate
the cuff and readjust it if skin becomes pinched.
4. Sit in a chair with your feet flat on the floor and place your left arm
on a table so that the cuff is at the same level as your heart.
5. Turn the monitor on, and after the Ready To Measure Symbol ( )
appears next to a zero on the digital panel, rapidly squeeze the
inflation bulb to inflate the cuff. Stop pumping when the numbers
on the display are approximately 40 mmHg higher than your
normal systolic blood pressure. Do not inflate higher than 280 mmHg.
6. The cuf
f will deflate automatically. Remain still throughout
the entire reading.
7. When measurement is complete, the monitor alternately displays
your blood pressure/pulse rate on the digital panel. Press the Air
Release Button to remove air in the cuff.
8. Wait 2-3 minutes before taking another blood pressure measurement.

A FEW WORDS ABOUT BLOOD PRESSURE
Blood pressure is the force on the walls
of your blood vessels as blood flows
through them.
Your heart is like a pump. When
it contracts, or beats, it sends a surge
of blood through the blood vessels
and pressure increases. This is called
your systolic pressure.
When your heart relaxes between
beats, your blood pressure decreases.
This is called your diastolic pressure.
When a doctor takes your blood
pressure, he or she measures
both your systolic and diastolic
pressures and records them as
numbers. For example, if your blood
pressure reading is 120/76 (120 over
76), your systolic is 120 and your
diastolic is 76. The numbers are
expressed in millimeters of mercury
120/76 mmHg.

A FEW WORDS ABOUT BLOOD PRESSURE
These two numbers provide important information about your health.
When blood pressure is consistently above normal it is called
hypertension (high blood pressure).
Your new ReliOn HEM-412CREL Manual Inflation Blood Pressure
Monitor measures your systolic and diastolic blood pressure for you,
then displays the results on an easy-to-read digital panel!
9
A FEW WORDS ABOUT BLOOD PRESSURE
Your blood pressure changes constantly. Blood pressure changes from
day to day and minute to minute according to your body’s condition.
For example, when you are exercising or angry your blood pressure
increases, but when you are relaxing or sleeping your blood
pressure decreases. These changes are completely normal. Your ReliOn
HEM-412CREL Manual Inflation Blood Pressure Monitor is
especially helpful when tracking changes in blood pressure because
it travels anywhere and takes just seconds to use.
NOTE: One or two readings will not determine your normal blood pressure.
It is very important to take regular, daily measurements and
to keep accurate records. In partnership with your doctor, an
accurate record of your blood pressure over a period of time
can be a valuable aid in diagnosing and preventing potential
health problems.

A FEW WORDS ABOUT BLOOD PRESSURE
• There is not a universally accepted definition of hypotension (low blood
pressure,) but a systolic pressure below 100 mmHg is usually
regarded as hypotension.
The World Health Organization (WHO) and The International Society
of Hypertension (ISH) jointly developed the following Blood Pressure
Classification. This classification, however, is only a general guideline
because your optimum blood pressure depends on your age, morbidity,
and treatment strategy by a physician. CONSULT YOUR PHYSICIAN
TO DETERMINE YOUR OPTIMUM BLOOD PRESSURE.
Systolic Diastolic
(mmHg) (mmHg)
Optimal < 120 < 80
Normal < 130 < 85
High-Normal 130-139 85-89
Stage 1 Hypertension (mild) 140-159 90-99

BATTERY INSTALLATION / REPLACEMENT
1. Slide the battery cover off in the direction
of the arrow.
2. Install 4 “AA” size batteries so + (positive)
and – (negative) polarities match the polarities
of the battery compartment as indicated.
3. Replace the battery cover.
NOTE: If the Low Battery Indicator appears on the
display, replace all four batteries.
Long-life alkaline batteries are recommended.
12
CARE AND MAINTENANCE
To k eep your digital blood pressure monitor in the best condition and
protect the unit from damage follow the directions listed below:
Clean the monitor with a soft dry cloth. Do not use any abrasive or
volatile cleaners. Do not attempt to clean the cuff. Never immerse the
monitor or any components in water.
Store the monitor in a safe and dry location. Do not fold the cuff
and tubing tightly. Do not subject the monitor to extreme hot or cold
temperatures, humidity and direct sunlight.
Av oid subjecting the monitor to strong shocks, such as dropping the
unit on the floor.
Remove the batteries if the unit will not be used for three months or
longer. Always replace all the batteries with new ones at the same time.
Use the unit consistent with the instruction provided in this manual.
Use only authorized parts and accessories.
13
SUGGESTIONS BEFORE TAKING
A MEASUREMENT
1. Avoid eating, smoking, and exercising 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. Remove tight-fitting clothing from your left arm.
4. Measurements should be taken in a quiet place.
5. Sit in a chair with your feet flat on the floor. Rest your left arm
on a table so that the 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 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.
8. Wait 2-3 minutes between measurements. The wait time allows the
arteries to return to the condition prior to taking the blood pressure
measurement. You may need to increase the wait time depending on
your individual physical characteristics.

HOW TO APPLY THE ARM CUFF
1. If the cuff is assembled correctly, the
sewn hook material will be on the
outside of the cuff loop and the
metal D-ring will not touch your skin.
2. Pass the end of the cuff furthest
from the tubing through the metal
D-ring to form a loop. The smooth
cloth should be on the inside of
the cuff loop.
3. Put your left arm through the cuff
loop. The bottom of the cuff should
be approximately 1/2 inch above
the elbow. The cuff tab on the cuff
should lie over the brachial artery
on the inside of the arm. Tube
should run down center of arm even
with middle finger.
