Greetings

Congratulations on purchasing a state-of-the-art A&D blood pressure monitor. Designed for ease of use and accuracy, this monitor will facilitate your daily blood pressure regimen. We recommend that you read through this manual carefully before using the monitor for the first time.

Intended Use

• The monitor is designed for use on adults only. Do not use on newborns or infants.
• Environment for use: This monitor is intended for use by individuals in a home healthcare environment.
• This monitor is designed to measure blood pressure and pulse rate of people for diagnosis.

Precautions

• Precision components are used in the construction of this monitor. Extremes in temperature, humidity, direct sunlight, shock or dust should be avoided.
• Clean the monitor 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 monitor 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 monitor and cuff are not water resistant. Prevent rain, sweat and water from soiling the monitor and cuff.
• Measurements may be distorted if the monitor is used close to televisions, microwave ovens, cellular telephones, X-ray or other devices with strong electrical fields.
• When using the monitor, confirm that the monitor is clean.
• 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.
• Do not modify the monitor. It may cause accidents or damage to the monitor.
• 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.
• Take care to avoid accidental strangulation of babies or infants with the hose.
• Do not twist the air hose during measurement. This may cause injury due to continuous cuff pressure.
• Wireless communication devices, such as home networking devices, mobile phones, cordless phones and their base stations, walkie-talkies can affect this blood pressure monitor. Therefore, a minimum distance of 30 cm (12”) should be kept from such devices.
• Measuring blood pressure too frequently may cause harm due to blood flow interference. Check that the operation of the monitor does not result in prolonged impairment of blood circulation, when using the monitor repeatedly.
• If you have had a mastectomy, please consult a doctor before using the monitor.
• Do not let children use the monitor by themselves and do not use the monitor in a place within the reach of infants. It may cause accidents or damage.
• There are small parts that may cause a choking hazard if swallowed by mistake by infants.
• Do not apply the cuff on an arm in which another medical device is attached. The equipment may not function properly.
• People who have a severe circulatory deficit in the arm must consult a doctor before using the monitor, 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 monitor where flammable gases such as anesthetic gases are present. It may cause an explosion.
• Do not use the monitor in highly concentrated oxygen environments, such as a high-pressure oxygen chamber or an oxygen tent. It may cause a fire or explosion.
• Unplug the AC adapter when not in use during the measurement.
• Use of accessories not detailed in this manual may compromise safety.
• Should the battery short-circuit, it may become hot and potentially cause burns.
• Allow the monitor to adapt to the surrounding environment before use (about one hour).
• Clinical testing has not been conducted on newborn infants and pregnant woman. Do not use on newborn infants or pregnant woman.
• Do not touch the batteries, the AC Adapter jack, and the patient at the same time. That may result in electrical shock.
• Do not inflate without wrapping the cuff around the upper arm.

• Replace the batteries two seconds or more after the monitor turns off.
• If (the LOW BATTERY mark) does not appear then the batteries are drained.
• The battery life varies with the ambient temperature and maybe shorter at low temperatures.
• Remove the batteries if the monitor is not to be used for a long time. The batteries may leak and cause a malfunction.
• Use the specified batteries only. The batteries provided with the monitor are for testing the monitor’s performance and may have limited life. Four new LR6 batteries will last approximately 3 months when used twice each day.

Using the Monitor

Connecting the Air Hose
Insert the air connector plug into the air socket firmly.
NOTE: Be sure to differentiate the Air Socket from the AC Adapter Jack. The Air Connector Plug will only securely fit into the correct jack.
Connecting the AC Adapter
Insert the AC adapter plug into the AC Adapter jack. Then, insert the AC adapter into an electrical outlet.

• When disconnecting the AC adapter from the electrical outlet, grasp and pull the AC adapter body out of
  the outlet.

• When disconnecting the AC adapter plug from the blood pressure monitor, grasp and pull the AC adapter plug our of the monitor.

Selecting the Correct Cuff Size
Using the correct cuff size is important for an accurate reading. A cuff that is too large will produce a reading that is lower than the correct blood pressure; a cuff that is too small will produce a reading that is higher than the correct blood pressure. With your arm hanging at the side of your body, measure the circumference of your upper arm at the midpoint between the shoulder and elbow.

Arm size| Recommended

Cuff size

| Replacement cuff

model #

---|---|---
16.5-23.6″ (42-60 cm)| Extra Large Cuff| UA-282A (Included)
14.2-17.7″ (36-45 cm)| Large Cuff| UA-281A
9.4-14.2″ (24-36 cm)| Medium Cuff| UA-280A

The Extra Large Cuff is designed to accommodate larger arm sizes measuring from 16.5-23.6″ (42-60 cm). This cuff is contoured to provide you with a quick and comfortable fit.

Applying the arm cuff

1. Wrap the cuff around the upper arm, about 0.5” (1-2 cm) above the inside of the elbow, as shown.
2. Place the cuff directly against the skin, as clothing may cause a faint pulse and result in a measurement error. Constriction of the upper arm, caused by rolling up a shirtsleeve, may prevent accurate readings.
3. Align the yellow Brachial Artery Marker on the cuff with the inside of your left elbow and fasten the cuff securely.
4. This cuff has an indicator which tells you whether you are using the correct cuff size or not. If the Index Mark falls within the Proper Fit Range, you are using the correct cuff size.

Adjusting the Built-in Clock
This monitor has a built-in clock that gives you the time and date and can tell you when a blood pressure reading stored in memory was taken. We recommend that you adjust the clock prior to use. To adjust the clock, follow these simple steps:

1. Press and hold the clock button until the digits start blinking.
2. To select the year, press and release the START button (to fast forward, press and hold the START button). When the current year is selected, set the year by pressing the clock button.
3. After the year is set, follow step 2 to set the month, day, hour (AM/PM) and minute on the display screen.
   NOTE: The clock will go back to January 1, 2020 at 12:00 if the batteries are removed for more than 30 seconds.

Setting the Alarm
This monitor allows you to set up to three alarms per day to notify you when to take your blood pressure. To set the alarm(s):

1. Press and hold the clock button until the year digits start blinking. Then press and release the memory button. “P-1” will be shown at the middle of the display screen indicating that this is the first alarm. NOTE: If you do not wish to set an alarm, press the memory button several times to return to the main screen or allow the display to disappear after 30 seconds.
2. Select the hour using the START button and press the clock button to set the hour and move to the minute selection. After selecting and setting the minute, press the memory button to complete the alarm setting.
3. The display will move onto the second alarm setting and conclude with the third alarm setting. Repeat the previous step if you need a second or third alarm.

When the alarm is set, a “P” will appear on the main screen. If you do not see a “P” on the main screen, press the clock button to activate the alarm function. When the alarm sounds, it will last for one minute. To turn the alarm off immediately, press the START button.
NOTE: To deactivate the alarm function, simply press the clock button once. You can reactivate the alarm function by pressing the clock button again.

Taking your Blood Pressure

This blood pressure monitor is designed to detect the pulse and to inflate the cuff to a systolic pressure level automatically.

Before Your Measurement:

• For 30 minutes prior to taking your blood pressure

  • Do not exercise
  • Do not drink coffee, caffeinated soda or alcohol
  • Do not smoke

• Sit quietly for 5-10 minutes

• Ensure you are using the right size cuff
  During Your Measurement:

• Do not talk

• Sit comfortably with your back straight and supported

• Uncross your legs and place feet flat on floor

• Rest arm on a table so that the cuff is at heart level

• Measure two times a day, in the morning and evening
  Notes for Accurate Measurement

• This monitor bases its measurements on the heartbeat. If you have a very weak or irregular heartbeat, the monitor may have difficulty determining your blood pressure.

• Should the monitor detect a condition that is abnormal, it will stop the measurement and display an error symbol. Refer to the section “Symbols” for the description of the symbols.

• If you have 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.

• 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.

• The monitor performance may be affected by excessive temperature or humidity, or altitude.

Normal Measurement

1. Place the cuff on the arm (preferably the left arm). Sit quietly during measurement.
2. Press the START button. The average of your last 3 readings and the total number of readings in memory will appear. As the cuff pressurizes, measurement will begin and the Cuff Inflation Meter will show on the display screen. It is normal for the cuff to feel very tight. Note: If an appropriate pressure is not obtained, the monitor automatically starts to inflate again. If you wish to stop inflation at any time, press the START button again.
3. When the measurement is complete, the systolic and diastolic pressure readings and pulse rate are displayed. The cuff deflates and the monitor automatically shuts off after 1 minute, or you can turn it off by pressing the START button.
4. Remove cuff and make note of your blood pressure and pulse rate.

Manual override of systolic pressure setting:
If your systolic pressure is expected to exceed 230 mmHg follow these steps:

1. Place the cuff on the left arm, unless your physician tells you otherwise.
2. Press and hold the START button until a number 30 to 40 mmHg higher than your expected systolic pressure appears.
3. Release the START button when the desired number is reached. 280 mmHg is the highest pressure level the monitor can reach. Measurement will then begin. Continue to measure your blood pressure.

The Cuff Inflation Meter is located on the left side of the display screen to tell you when the blood pressure monitor is inflating and deflating the cuff. The Cuff Inflation Meter moves up during inflation and moves down during deflation.

Average Reading

This monitor provides an average of the last 3 blood pressure readings. When taking a measurement, the average blood pressure reading will appear and flash several times before the cuff begins to inflate. The average blood pressure reading will also appear briefly when you recall the measurements stored in memory.

Memory

This monitor automatically stores up to sixty (60) blood pressure and pulse measurements in memory. Measurements stored in memory are assigned an index number in the order of the newest to the oldest.
To retrieve readings, follow these simple steps:

1. When the display screen is showing only the time, press and quickly release the Memory (“M”) button. You will see the date (month and day) and time of the most recent blood pressure that was taken followed by the measurement.
2. If you want to retrieve other measurements in memory, press and release the Memory button repeatedly until the desired date and time of the measurement are reached. The measurement will then be displayed.
3. The display will shut off automatically a few seconds after the readings are displayed.

If there are no measurements stored in memory, you will see dashes in the date and time fields followed by a measurement of three 0s displayed vertically. To clear the measurement history from memory, press and hold the Memory button for at least five seconds while the display screen is showing only the time. Release the Memory button when you see the M symbol in upper left hand corner of the display flash and disappears. This indicates that the memory has been cleared.
NOTE: Stored measurements, time, date, and alarm settings will be lost if batteries become low or are removed for more than 30 seconds.

What is an Irregular Heartbeat

An irregular heartbeat is defined as a hearbeat that varies from the average of all heartbeats. When the monitor detects an irregular rhythm during the measurements, the IHB indicator will appear on the display with the measurement values.

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 keep it under control:

• Do not smoke
• Reduce salt and fat intake
• Maintain proper weight
• Exercise regularly
• Have regular physical checkups

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.

Blood Pressure Variations
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 by the results of one measurement. 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 the date and time when recording your blood pressure. Consult your doctor to interpret your blood pressure data.
