• The arm size is printed on each cuff.
• The index and proper fit range, on the cuff, tell you if you are applying the correct cuff. Refer to “6.5 Applying The Arm Cuff”.
• If the index points outside of the range, contact your local dealer to purchase a replacement cuff.
• The arm cuff is consumable. If it becomes worn, purchase a new one.

Arm size: The circumference at the biceps.

Symbols are printed on the cuff

Applying The Arm Cuff

1. Wrap the cuff around the upper arm, about 1 to 2 cm above the inside of the elbow, as shown. Place the cuff directly against the skin, as clothing may cause a faint pulse and result in a measurement error.
2. Constriction of the upper arm, caused by rolling up a shirtsleeve, may prevent accurate readings.
3. Confirm that the index points are within the proper fit range.

Note: During measurement, it is normal for the cuff to feel very tight. (Do not be alarmed).

Measurements

Normal Measurement

1. Place the cuff on the arm at heart level (preferably the left arm). Sit quietly during measurement.

2. Press the START button. All of the display segments are displayed. Zero is displayed blinking briefly. Then the display changes, as indicated in the figure at the right, 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, as in the figure at the right, during inflation.
   Note: If you wish to stop inflation at any time, press the 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.
   Note: If an appropriate pressure is not obtained, the device starts to inflate again automatically.

4. When the measurement is complete, the systolic and diastolic pressure readings and pulse rate are displayed. The cuff exhausts the remaining air and deflates completely.

5. Press the START button again to turn off the power.
   Note: The device is provided with an automatic power shut-off function. Allow at least 3 minutes between measurements on the same person.

Measurement with the Desired Systolic Pressure

If re-inflation occurs repeatedly, use the following methods. If your systolic pressure is expected to exceed 230 mmHg, use this procedure.

1. Place the cuff on the arm at heart level (preferably the left arm).
2. Press the START button.
3. During the zero blinks, press and hold the START button until a number about 30 to 40 mmHg higher than your expected systolic pressure appears.
4. When the desired number is reached, release the START button to start measurement. Then continue to measure your blood pressure as described on the section

Normal Measurement

Notes for Accurate 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.
• Sit down in a comfortable position. Place your arm on a table with your palm facing upward and the cuff at the same level as your heart.
• Place the center of the cuff at the same level as your heart.
• Relax for about five to ten minutes before 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.
• 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.
• An individual’s 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 the section “5 Symbols” for the description of the symbols.
• This device is intended for use by adults. Consult with your physician before using this device on a child. A child should not use this device unattended.
• Try to measure your blood pressure at the same time every day.
• The automatic blood pressure monitor’s performance may be affected by excessive temperature or humidity, or altitude.

Recalling the Memory Data

The device automatically stores up to sixty blood pressure and pulse measurements in memory. Data stored in memory are assigned a data number in the order of the newest to the oldest. The oldest data displays as ” M “. The symbol in the upper left corner of the display indicates that you are viewing previous data stored in memory.

Recalling Data

1. When nothing is displayed, press and hold the START button to recall the stored data.
2. Release the button when displaying the average data.
3. The data number and stored data are automatically displayed in order from the last measurement.
4. The display will turn off automatically after all data is displayed.

Note: If you press the START button while recalling data, the device turns off.

Clearing Data

1. When turning off the device, press and hold the START button until the “CLr no ” is displayed.
2. Select “CLr YES” to clear data.
3. Data is cleared when the mark blinks.
4. The device turns off automatically.

What is the I.H.B./AFib

When the monitor detects an irregular rhythm during the measurements, the I.H.B./AFib indicator will appear on the display with the measurement values.

Note: We recommend contacting your physician if you see this I.H.B./AFib symbol frequently.

What is AFib

The heart contracts due to electrical signals occurring in heart and sends blood through the body. Atrial fibrillation (AFib) occurs when the electrical signal in the atrium becomes confused and leads to disturbances in the pulse interval. AFib can cause blood to stagnate in the heart, which can easily create clots of blood, a cause of stroke and heart attack.

Pressure Bar Indicator

The indicator monitors the progress of pressure during measurement.

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.

WHO Classification Indicator

Each segment of the bar indicator corresponds to the WHO blood pressure classification.

• The indicator displays a segment, based on the current data, corresponding to the WHO classification.
