Precautions Precision components are used in the construction of this device. Extremes in temperature, humidity, direct sunlight, shock or dust should be avoided. Clean the device and cuff with a dry, soft cloth or a cloth dampened with water and a neutral detergent. Never use alcohol, benzene, thinner or other harsh chemicals to clean the device or cuff. Avoid tightly folding the cuff or storing the hose tightly twisted for long periods, as such treatment may shorten the life of the components. The device and cuff are not water-resistant. Prevent rain, sweat and water from soiling the device and cuff. Measurements may be distorted if the device is used close to televisions, microwave ovens, cellular telephones, X-ray or other devices with strong electrical fields. Used equipment, parts and batteries are not treated as ordinary household waste, and must be disposed of according to the applicable local regulations. When the AC adapter is used, make sure that the AC adapter can be readily removed from the electrical outlet when necessary. When reusing the device, confirm that the device is clean. Do not modify the device. It may cause accidents or damage to the device. To measure blood pressure, the arm must be squeezed by the cuff hard enough to temporarily stop blood flow through the artery. This may cause pain, numbness or a temporary red mark to the arm. This condition will appear especially when measurement is repeated successively. Any pain, numbness, or red marks will disappear with time.

Contraindications The following are precautions for proper use of the device. Do not apply the cuff to an arm with another medical electrical equipment attached. The equipment may not function properly. People who have a severe circulatory deficit in the arm must consult a doctor before using the device, to avoid medical problems. Do not self-diagnose the measurement results and start treatment by yourself. Always consult your doctor for evaluation of the results and treatment. Do not apply the cuff on an arm with an unhealed wound. Do not apply the cuff on an arm receiving an intravenous drip or blood transfusion. It may cause injury or accidents. Do not use the device where flammable gases such as anesthetic gases are present. It may cause an explosion.

How To Take Proper Measurements For the most accurate blood pressure measurement: Sit comfortably on a chair. Rest your arm on the table. Do not cross your legs. Keep your feet on the floor and straighten your back. Relax for about five to ten minutes before measurement. Place the center of the cuff at the same height as your heart. Remain still and keep quiet during measurement. Do not measure immediately after physical exercise or a bath. Rest for twenty or thirty minutes before taking the measurement. Try to measure your blood pressure at the same time every day.

Measurement (Operation) During measurement, it is normal for the cuff to feel very tight. Select a measurement mode (operation of the device). Normal measurement with storing data : ... Press the START 1 or START 2 button. Unrecorded measurement : ... Press both START buttons simultaneously. Recalling data : ...Press and hold the START 1 or START 2 button to recall data. Clearing data : ...Remove the batteries and re-install them.

After Measurement After the measurement has completed, remove the cuff and record your data, then press the START 1 or START 2 button to turn off the power. Note: The device has an automatic power shut-off function, which turns the power off approximately one minute after measurement. Allow at least three minutes between measurements on the same person. English 7

Measurements Model UA-774 is designed to detect the pulse and to inflate the cuff to a systolic pressure level automatically. If your systolic pressure is expected to exceed 230 mmHg, read "Measurement with the desired systolic pressure" on the next page. Model UA-774 can store the last thirty sets of data for each button. We recommend that if two people regularly use the device, one uses the START 1 button and the other uses START 2 button, to prevent confusion over stored data.

Normal Measurement With Storing Data 1. Place the cuff on the arm (preferably the left arm). Sit quietly during measurement. 2. Press the START 1 (or START 2 ) button. The average blood pressures and last data number are displayed briefly. Then current pressure is displayed, as the measurement begins. The cuff starts to inflate. It is normal for the cuff to feel very tight. A pressure bar indicator is displayed during measurement.

At heart level Either START button Averaged data Data number Inflation in progress

Note: If you wish to stop inflation at any time, press either START button again. 3. When inflation is complete, deflation starts automatically and the (heart mark) blinks, indicating that the measurement is in progress. Once the pulse is detected, the mark blinks with each pulse beat.

Pressurizing Measurement in progress

Note: If an appropriate pressure is not obtained, the device starts to inflate again automatically. Systolic pressure 4. When the measurement is complete, the systolic and diastolic pressure readings and pulse rate are displayed and stored. The cuff exhausts the remaining air and deflates completely. 5. Press either START button again to turn off the power.

Notes For Proper Measurement Sit down in a comfortable position. Place the arm to be used for the measurement on a table or other support so that the center of the cuff will be at the same height as your heart. Relax for about five to ten minutes before taking a measurement. If you are excited or depressed by emotional stress, the measurement will reflect this stress as a higher (or lower) than normal blood pressure reading and the pulse reading will usually be faster than normal. Your blood pressure varies constantly, depending on what you are doing and what you have eaten. What you drink can have a very strong and rapid effect on your blood pressure. This device bases its measurements on the heartbeat. If you have a very weak or irregular heartbeat, the device may have difficulty determining your blood pressure. Should the device detect a condition that is abnormal, it will stop the measurement and display an error symbol. Refer to page 4. Model UA-774 is intended for use by adults only. Consult with your physician before using this device on a child. A child should not use this device unattended. English 9

Operation Mode 1. Normal measurement with storing data (Refer to page 8) Press the START 1 (or START 2) button. Blood pressure is measured and data is stored within the device. The device can store the last thirty sets of data for each button. We recommend that if two people regularly use the device, one uses the START 1 button and the other uses START 2 button. Recalling data Press and hold the START 1 (or START 2) button to recall the data. Stored data are automatically displayed in order from the last data. Clearing data Remove batteries to clear all data. Re-install them again.

What Is An Irregular Heartbeat? Model UA-774 blood pressure monitor provides a blood pressure and pulse rate measurement even when an irregular heartbeat occurs. An irregular heartbeat is defined as a heartbeat that varies by 25% from the average of all heartbeats during the blood pressure measurement. It is important that you are relaxed, remain still and do not talk during measurements. indicator frequently. Note: We recommend contacting your physician if you see this

About Blood Pressure What Is Blood Pressure? Blood pressure is the force exerted by blood against the walls of the arteries. Systolic pressure occurs when the heart contracts. Diastolic pressure occurs when the heart expands. Blood pressure is measured in millimeters of mercury (mmHg). One's natural blood pressure is represented by the fundamental pressure, which is measured first thing in the morning while one is still at rest and before eating.

What Is Hypertension And How Is It Controlled? Hypertension, an abnormally high arterial blood pressure, if left unattended, can cause many health problems including stroke and heart attack. Hypertension can be controlled by altering lifestyle, avoiding stress, and with medication under a doctor’s supervision. To prevent hypertension or to keep it under control: Do not smoke Exercise regularly Reduce salt and fat intake Have regular physical checkups Maintain proper weight

Why Measure Blood Pressure At Home? Blood pressure measured at a clinic or doctor's office may cause apprehension and can produce an elevated reading, 25 to 30 mmHg higher than that measured at home. Home measurement reduces the effects of outside influences on blood pressure readings, supplements the doctor's readings and provides a more accurate, complete blood pressure history.

Standards to assess high blood pressure, without regard to age, have been established by the World Health Organization (WHO), as shown in the chart at the right.

Blood Pressure Variations

Blood Pressure

An individual’s blood pressure varies greatly on a daily and seasonal basis. It may vary by 30 to 50 mmHg due to various conditions during the day. In hypertensive individuals, variations are even more pronounced. Normally, the blood pressure rises while at work or play and falls to its lowest levels during sleep. So, do not be overly concerned Typical fluctuation within a day (Measured every five minutes) by the results of one measurement. mmHg Systolic Take measurements at the same time every day using the procedure described in this manual to get to know your normal blood pressure. Regular readings give a more comprehensive blood pressure history. Be sure to note date and time when Diastolic Sleep recording your blood pressure. Consult your doctor to interpret your PM AM Time blood pressure data.
