INTRODUCTION

Thank you for purchasing the Omron HEM-422CRLC 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.

The Omron HEM-422CRLC digital blood pressure monitor 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 Omron HEM-422CRLC 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 over 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.

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.

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.

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 Heart Symbol
( ) appears next to a zero. Wait for the Heart
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.

( ) appears on the display, push the
Air Release Button to release any
air left in the cuff.

7. Press ON/OFF button to turn monitor off.

NOTE: Wait 2-3 minutes before taking

another blood pressure measurement.
