Your new 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. The monitor stores measurement results for two people and features Morning and Evening Averages. TruReadTM allows for three consecutive measurements with timed intervals for an average reading.
Omron Health Management Software included with this unit allows you to view, process and print data about blood pressure measured by the HEM-790IT.
The HEM-790IT comes with the following components:
• Monitor |
• ComFitTM Cuff • AC Adapter |
•4 “AA” Batteries • Storage Case
•Instruction Manual printed in English and Spanish
• USB Cable |
• CD-ROM |
• Warranty Card |
The HEM-790IT IntelliSense® Automatic Blood Pressure Monitor is intended for home use.

Indicates a potentially hazardous situation
WARNING which, if not avoided, could result in death or serious injury.
Indicates a potentially hazardous situation
which, if not avoided, may result in minor or CAUTION moderate injury to the user or patient or
damage to the equipment or other property.
OPERATING THE DEVICE
Contact your physician for specific information about your blood pressure. Self-diagnosis and treatment using measured results may be dangerous. Follow the instructions of your physician or licensed healthcare provider.
If battery fluid should get in your eyes, immediately rinse with plenty of clean water. Contact a physician immediately.
Read all of the information in the instruction manual and any other literature in the box before operating the unit.
This device is intended for use in measuring blood pressure and pulse rate in the adult population. Do not use this device on infants or persons who cannot express their intentions.
5
SAFETY INFORMATION
OPERATING THE DEVICE (continued)
Read the Special Conditions section (page 36) of the instruction manual if your systolic pressure is known to be more than 220 mmHg. Inflating to a higher pressure than necessary may result in bruising where the cuff is applied.
Operate the device only as intended. Do not use the device for any other purpose.
Dispose of the device, components and optional accessories according to applicable local regulations. Unlawful disposal may cause environmental pollution.
Do not use a cellular phone near the device. It may result in an operational failure.
Use only Omron authorized parts and accessories. Parts and accessories not approved for use with the device may damage the unit.
Use only 1.5V manganese or alkaline batteries with this device. Do not use other types of batteries. This may damage the unit.
Do not play the CD-ROM disc included with this monitor on general audio players, DVD players or personal game devices. It may damage the speaker of the device and may harm your eardrums.

SAFETY INFORMATION
RISK OF ELECTRICAL SHOCK
Do not plug or unplug the power cord into the electrical outlet with wet hands.
Do not overload power outlets. Plug the device into the appropriate voltage outlet.
CARE AND MAINTENANCE
Do not subject the monitor to strong shocks, such as dropping the unit on the floor.
Do not submerge the device or any of the components in water.
Store the device and the components in a clean, safe location.
Changes or modification not approved by Omron Healthcare will void the user warranty. Do not disassemble or attempt to repair the unit or components.
7
BEFORE TAKING A MEASUREMENT
To ensure a reliable reading follow these recommendations:
1.Avoid eating, drinking alcohol, smoking, exercising, and bathing 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.Measurements should be taken in a quiet place.
4.Remove tight-fitting clothing from your arm.
5.Sit in a chair with your feet flat on the floor. Rest your 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 may 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 about the same time each day for consistency.

DISPLAY SYMBOLS
The American Heart Association1 recommends the following guideline for upper limit of normal for home blood pressure readings:
AHA Home Guideline for Upper Limit of Normal BP
Systolic Blood Pressure |
135 mmHg |
Diastolic Blood Pressure |
85 mmHg |
This is a general guideline because blood pressure depends on age and morbidity. The AHA recommends a lower home blood pressure goal for certain patients, including diabetic patients, pregnant women, and patients with renal failure1.
The monitor is not intended to be a diagnostic device.
WARNING
Contact your physician for specific information about your blood pressure. Self-diagnosis and treatment using measured results may be dangerous. Follow the instructions of your physician or licensed healthcare provider.
Omron Healthcare recommends you contact your physician if the MORNING HYPERTENSION SYMBOL and/or the HEARTBEAT SYMBOL appear on the display with your measurement values.
MORNING HYPERTENSION SYMBOL (
)
The Morning Hypertension Symbol is displayed if the morning average reading for a week is above 135 for the Systolic Blood Pressure value and/or 85 for the Diastolic Blood Pressure value when viewing the Morning Averages and the Evening Averages in the memory.
