Thank you for purchasing the Omron HEM-412C Manual Inflation
Blood Pressure Monitor. This easy-to-use monitor quickly detects
your blood pressure and pulse measurements and displays them on
a large, clear digital panel.
Your new HEM-412C uses 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 monitor features an easy-to-squeeze inflation
bulb that allows you to quickly fill the cuff with air. Stop pumping and the
cuff deflates automatically. Error indicators alert you to incorrect procedures
and an automatic power-off function conserves batteries.
Please read this instruction manual thoroughly before using the
Omron HEM-412C Manual Inflation Blood Pressure Monitor.
For specific information on your own blood pressure,
CONTACT YOUR PHYSICIAN.

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'' 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.
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. After the Ready To Measure Symbol ( ) appears next to a zero
on the digital panel, quickly 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.
7. The cuff will deflate automatically. Remain still throughout
the entire reading.
8. When measurement is complete, the monitor alternately
displays your blood pressure and pulse on the digital panel.
9. Wait 5-10 minutes before taking another blood pressure
measurement. You may need more rest time between
readings depending on your individual physical characteristics.
QUICK REFERENCE GUIDE

6
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.
4. If the Low Battery Indicator appears
on the display, replace all four batteries.
Long-life alkaline batteries
are recommended.
5. Remove the batteries if the monitor will
not be used for an extended period of time.

HOW TO APPLY THE ARM CUFF
1. Locate your brachial artery by
pressing two fingers approximately
one inch above the elbow crease on the
inside of the left arm. Determine where
your pulse is strongest.
2. The cuff should be assembled
correctly when it is removed from
the box. If it is not, 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. 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.
4. 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 should lie over
the brachial artery on the inside
of the arm.

HOW TO APPLY THE ARM CUFF
5. Pull the cuff so that the top and
bottom edges are tightened evenly
around your arm.
6. When the cuff is positioned correctly,
press the sewn hook material FIRMLY
against the pile side of the cuff.
7. Make certain the cuff fits snugly
around your arm. The cuff should
make good contact with your skin.
8. Sit in a chair with your feet flat on the
floor and place your arm on a table so
that the cuff is at the same level
as your heart.
9. Relax your arm and turn your
palm upward.
10. Be sure there are no kinks in
the air tubing.

HOW TO TAKE A READING
1. Press the On/Off button.
a) All display symbols appear
for about one second. This is the
initial LCD Test.
b) The display symbols
disappear and the Deflation
Indication Symbol ( )
starts to flash.
c) When the monitor completes
the necessary preparations
before measurement, the
Ready To Measure Symbol
( ) appears next to a zero.
NOTE: Wait for the Ready To Measure
Symbol ( ) before taking a measurement.
2. Begin inflating the cuff by rapidly squeezing the inflation bulb
until you have reached approximately 40 mmHg higher than
your normal systolic reading. If your normal systolic blood
pressure is unknown, inflate the cuff to 180 mmHg.

6. When the Deflation Indication Symbol ( ) appears on the
display, push the air release button to release any air left in the cuff.
NOTE: Wait 5-10 minutes before taking another blood pressure measurement.
Waiting allows the engorged blood vessels to return to normal. You may require
more rest time between readings depending on your individual
physical characteristics.
REMEMBER TO KEEP A RECORD OF YOUR BLOOD PRESSURE
AND PULSE MEASUREMENTS.

HOW TO TAKE A READING
3. Stop pumping the inflation bulb when
you have reached your correct inflation
level and remain still. The cuff will
begin to deflate automatically.
4. As the cuff deflates, decreasing
numbers appear on the display.
The Ready To Measure Symbol
( ) flashes at the onset of
oscillation signals.
5. When measurement is complete,
the Ready To Measure Symbol
( ) stops flashing and your blood
pressure and pulse display alternately.
