This remarkable, compact and easy to use instrument is ideal for people who frequently monitor their own blood pressure. The small, pre-formed wrist cuff is very convenient and easy to apply. With the push of a button the OMRON Wrist Blood Pressure Monitor measures your blood pressure and pulse and displays the reading on a clear digital panel. Perfect for quick, easy readings at home, at work, and while traveling. It also stores up to 90 sets of measurements in memory and displays an average reading based on the three most recent measurements. The OMRON Wrist Monitor uses the oscillometric method of blood pressure measurement. This means the monitor detects the pulse wave vibrations in the artery of your wrist and converts the oscillations into a digital reading. Clinical research has proven a direct relationship between blood pressure in the wrist and blood pressure in the arm. Changes in wrist blood pressure reflect changes in arm blood pressure because the arteries in the wrist and the arm are connected. Frequently measuring the blood pressure in your wrist will provide you and your doctor with an accurate indication of changes in your true blood pressure. Please read this instruction manual thoroughly before using the unit. For specific information about your own blood pressure, consult your doctor. 2 Notes on Safety The OMRON IW2 is not suitable for measuring the frequency of cardiac pacemakers. You should never change the dosage of medication prescribed by your doctor. People with poor peripheral circulation may find that results for measurements taken at the wrist vary from those taken on the upper arm. Use the OMRON IW2 only for yourself. Caution Self-diagnosis of measured results and treatment are dangerous. Please follow the instructions of your doctor. Do not use the unit on infants or persons who cannot express their consent. Do not use the unit for any purpose other than measuring blood pressure. Do not use a cellular phone, or other devices that emit electromagnetic fields, near the unit. This may result in incorrect operation of the unit. Battery liquid may leak and damage the main unit. Please observe the following points. · When you are not going to use the unit for a long period of time (approximately three months or more), take out the batteries. · Replace old batteries with new ones immediately. · Do not use old and new batteries together. · Do not insert the batteries with their polarities incorrectly aligned. 3 Know Your Unit Main Unit Wrist Cuff Display MEM Button START/STOP Button Battery Compartment SET Button Heart Symbol (Flashes when the monitor is at the correct position.)

To avoid pressure on the button when transporting or storing, use the case provided. · Dispose of batteries according to applicable local regulations. Battery Installation/Replacement 7 Initial Set-Up How to Set the Date and Time Your blood pressure monitor automatically stores up to 90 measurement values in its memory and calculates an average value based on the last three measurements. To make use of the memory and average value function: · Set the monitor to the correct date and time before taking a measurement for the first time. · If the batteries have been removed for a long period of time, the date and time setting will need to be reset. 1. When the batteries are installed for the first time, the year digits (2004) will flash on the display when you turn on the monitor. Note: * The range for the year setting is 2004 to 2030. If the year reaches 2030, it will return to 2004. * If you need to reset the date and time, press the SET button until the setting you want to adjust appears on the display, then press the MEM button to change the setting. 2. Press the MEM button to advance the digits one at a time. Note: * If you hold down the MEM button, the digits will advance rapidly. 3. Press the SET button to confirm the setting when the desired number appears on the display. The year setting is set and the month digits will flash. 8 How to Set the Date and Time Initial Set-Up 4. Repeat steps 2 and 3 to set the month and date (day). 5. Repeat steps 2 and 3 to set the hour and minutes for the time. Note: * The monitor will automatically turn itself off after you press the SET button to confirm the minute setting. How to Set the Date and Time 9 Correct Usage How to Apply the Wrist Cuff 1.

Alternating display * The time and date of the measurement are displayed alternately. Important: * Your blood pressure monitor includes an irregular heartbeat feature. Irregular heartbeats can influence the results of the measurement. The irregular heartbeat function automatically determines if the measurement is usable or needs to be repeated. If the measurement results are affected by irregular heartbeats but the result is valid, the result is shown together with the irregular heartbeat symbol ( ). If the irregular heartbeats cause the measurement to be invalid, no result is shown. If the irregular heartbeat symbol ( ) is shown after you have taken a measurement, repeat the measurement. If the irregular heartbeat symbol ( ) is shown frequently, please notify your doctor. Note: * Do not use this monitor to measure blood pressure for more than one person since the measurement values are automatically stored in memory and an average value based on the last three measurements is calculated. 12 How to Take a Reading Correct Usage What is Irregular Heartbeat? An irregular heartbeat is a heartbeat Normal Heartbeat rhythm that varies by more or less Pulse than 25% from the average Blood pressure heartbeat rhythm detected while the unit is measuring the systolic and Irregular Heartbeat diastolic blood pressure. Short Long If such an irregular rhythm is Pulse detected more than twice during Blood pressure measurement, the irregular heartbeat symbol ( ) appears on the display when the measurement results are displayed. What is Arrhythmia? A heartbeat is stimulated by electrical signals that cause the heart to contract. Arrhythmia is a condition where the heartbeat rhythm is abnormal due to flaws in the bio-electrical system that drives the heartbeat. Typical symptoms are skipped heartbeats, premature contraction, an abnormally rapid (tachycardia) or slow (bradycardia) pulse. This can be caused by heart disease, aging, physical predisposition, stress, lack of sleep, fatigue etc. Arrhythmia can only be diagnosed by a doctor through a special examination. Whether the appearance of the irregular heartbeat symbol ( ) in the results indicates arrhythmia or not can only be determined by an examination and diagnosis by your doctor. If the irregular heartbeat symbol ( ) is shown frequently, please notify your doctor. Conducting self-diagnosis and treatment ...
