SERIAL NUMBER: _________________
Staple your purchase receipt here
Your OMRON HCG-801 is an easy-to-use electrocardiograph unit that can record and store
electrocardiogram (ECG) measurements of your heart rhythm. Each ECG reading records an approximately
30-second measurement and these ECG readings can help your doctor monitor your condition. It also
includes guidance screens to help you obtain good data when taking measurements. This unit is intended for
use on the adult population.
The monitor is supplied with an SD memory card that can store up to 300 measurements, including the ECG
data along with the date and time of measurement. Storing ECG data on the SD memory card, or in unit
memory, allows your doctor to view them later.
IMPORTANT: Please note that while the measurements from an ECG monitor are a useful guide for your
doctor, they cannot detect all changes in heart conditions. Always consult your doctor if you
notice any change in your condition, regardless of the measurement results. Consult a
doctor even if “Regular heart rate, Regular heart rhythm” is displayed as the data message,
if you have been diagnosed with a heart condition.
The HCG-801 comes with the following components:
• Main Unit • SD Memory Card • Storage Pouch • 2 × LR03(AAA) Batteries
• Instruction Manual* • Registration Card • Quick Reference Card
* The illustrations used in this manual may differ slightly from the appearance of the actual unit.
SAVE THESE INSTRUCTIONS
Before Using the Unit
The heart is a muscular pump controlled by electrical impulses generated by the body. It is divided into two
sides by the septa and each side has two chambers – an atrium and a ventricle – linked by a one-way valve.
The left atrium and ventricle control oxygenated blood, and the right atrium and ventricle de-oxygenated
(“used”) blood.
The electrical impulse that causes the heart to beat spreads across the atria, causing the left and right atria to
contract and pump blood into the left and right ventricles respectively. The two ventricles then contract and
pump blood out of the heart. The heart muscle then relaxes, or re-polarizes, allowing blood to fill up the
heart again.
An ECG monitor is able to measure the electrical impulse as it passes across and through the heart, causing
the heart to beat. An ECG does not measure the movement of your heartbeat, but rather the electrical
activity that causes the heart to beat. The measurements recorded by an ECG monitor, when combined with
a medical examination, can help your doctor monitor your heart condition. The ECG measurements
recorded by the unit are NOT designed or intended for medical diagnosis. Conditions such as arrhythmia
can only be diagnosed by a doctor through a special examination.

In order to obtain a good ECG reading, it is important that measurements are taken correctly.
Before taking a measurement for the first time, read these instructions carefully and make sure you observe
the following points each time you take a measurement.
• Make sure that the electrodes are directly touching your skin.
• If your hands or skin is dry, wipe them with a damp towel so that they are slightly moist.
• If the electrodes are dirty, wipe any dirt off with a soft cloth or a cotton swab moistened with
disinfectant alcohol.
- Do not use too much disinfectant alcohol when cleaning the electrodes.
- Do not use disinfectant alcohol to clean the unit except the electrodes.
• Do not move during measurement.
- Movement including talking, coughing, or sneezing during measurement can affect the
measurement results.
• If the position of your finger or arm is inappropriate during measurement, the results may be
inaccurate, so be sure to check their positions before taking a measurement. (Refer to page 25.)
• After taking a measurement, disinfect the electrodes by wiping them with a soft cloth or cotton swab
moistened with disinfectant alcohol. If you do not disinfect the electrodes there is a risk of skin

same as medical diagnosis. Please consult your doctor for proper
interpretation.” Next, the guidance screens are displayed.
NOTES:
• You can press the START button to begin a measurement even
while the guidance screens are being displayed.
• The word “electrode” in this Instruction Manual is described as
“sensor” in the guidance screen.
2. Make sure that you are in a relaxed position.
The ideal posture is one where you are seated comfortably with your back straight.
NOTE: You can also take a measurement while you are standing or while lying down.
3. Place your index finger so that it fits closely over the two finger
electrodes.
NOTE:
• Take care not to press the START button until you are ready to
take the measurement.
WARNING: Even if you are left-handed, use your right hand
to take a measurement.

5. While maintaining the same posture, press the START button.
The measurement takes about 30 seconds to complete. The unit beeps every second during measurement.
During measurement, the screen displays the ECG waveform. The progress bar at the bottom of the
screen displays measurement progress, and the number on the right shows the heart rate.
Depending on the waveform, situations can occur in which the unit cannot assess and display the heart
rate during the measurement.
NOTES:
• During measurement the unit will only respond to the ON/OFF / STOP button to discontinue the
measurement.
• If the contact of the electrodes becomes loose, or the conditions change during measurement, the
measurement may not be correct.
IMPORTANT: Keep still and do not move until the measurement is complete.
