1. Introduction

Thank you for purchasing the BIOS Diagnostics

Ultra Blood Pressure Monitor with Atrial Fibrillation Screening.

Designed for convenient and easy operation, this device provides a simple, yet accurate method to measure your blood pressure.

Your blood pressure is an important parameter that can be used to monitor your health. This device enables you to monitor your blood pressure regularly, and maintain a record of your blood pressure measurements. You can then use this record to assist your physician in diagnosing and maintaining a healthy blood pressure level.

1.1 Features

The 3MS1-4K is a fully automatic, digital, blood pressure measuring device with a unique fuzzy logic technology as well as patented MAM and AFIB technologies. It can store up to 200 blood pressure readings.

It provides a fast and reliable measurement of systolic and diastolic blood pressure as well as heart rate using the oscillometric measurement method.

AFIB detection is the world’s leading digital blood pressure measurement technology for the early detection of atrial fibrillation (AFIB) and hypertension. These are the two top risk factors of heart disease and stroke which increase the risk of getting a stroke or heart disease in the future. It is important to detect AFIB and hypertension at an early stage, even though you may not experience any symptoms. Appropriate treatment can reduce your risk of suffering a stroke. For this reason, it is recommended that you visit your doctor when the device gives an AFIB signal during your blood pressure measurement. The AFIB algorithm has been clinically investigated by several prominent clinical investigators and showed that the device detects patients with AFIB at 97-100% certainty.

MAM - Averaging Mode technology used in the device provides accurate measurements. Using three consecutive measurements, your result is calculated and displayed as a single averaged measurement on the display screen.

AFIB -Atrial Fibrillation Detector technology icon is displayed when atrial fibrillation is detected during a blood pressure reading.

Blood Pressure Analyzer Software allows you to download, record and chart your readings to accurately monitor your daily readings. The Blood Pressure software can be downloaded for free from

This powerful medical tool automatically stores all your blood pressure readings. By clicking the viewing options the user can review the readings in multiple forms including: by date, morning vs. evening readings, isolated systolic or diastolic or pulse. The automatic graph clearly shows your blood pressure history with highs and lows. Charts and graphs can even be printed or emailed to your doctor!

This device is easy to use and has been proven in clinical studies to provide excellent accuracy. Before using the

3MS1-4K, read this instruction manual carefully and keep it in a safe place.

1.2 Important Information

Refer to the following sections to learn about important safety instructions and how to take care of the

BIOS Diagnostics

Premium Blood Pressure Monitor with Atrial Fibrillation Screening.

1.2A Safety Information

• Self-measurement means control, not diagnosis or treatment. Your values must always be discussed with your doctor or a physician who is familiar with your family history.

• If you are undergoing medical treatment and receiving medication, consult your doctor to determine the most appropriate time to measure your blood pressure. Never alter the dosages of any medication without direction from your doctor.

• Your blood pressure depends on several factors, such as age, gender, weight, and physical condition. It also depends on the environment and your state of mind at the time of measurement. In general, your blood pressure is lower when you are asleep and higher when you are active. Your blood pressure may be higher when recorded at a hospital or a clinic and may be lower when measured in the relaxing comfort of your home.

Due to these variations, we recommend that you record your blood pressure regularly at home as well as at your doctor’s clinic.

• Try to record your blood pressure regularly at the same time of the day and under the same conditions.This will help your physician detect any extreme variations in your blood pressure and thus treat you accordingly.

• Morning Hypertension ( > 135 / 85 mm Hg): Recently, several studies have identified elevated cardiovascular risks (heart failure, stroke, angina) associated with “morning hypertension”. There is a typical rise in blood pressure during the physiological changes from sleep to arising for the day.

• The ideal time to measure your blood pressure is in the morning just after you wake up, before breakfast and any physical activity, and in the absence of the urge to urinate. If this is not possible, try to take the measurements later in the morning, before you start any physical activity. Relax for a few minutes before you record your blood pressure.

• Your blood pressure increases or decreases under the following circumstances:

Blood pressure is higher than normal:

— when you are excited, nervous, or tense

— while taking a bath

— during and after exercise or strenuous physical activity

— when it is cold

— within one hour after meals

— after drinking tea, coffee, or other caffeinated drinks

— after smoking tobacco

— when your bladder is full

Blood pressure is lower than normal:

— after consuming alcohol

— after taking a bath

• The pulse display is not suitable for checking the frequency of heart pacemakers.

• If you have been diagnosed with a severe arrhythmia or irregular heartbeat, vascular constriction, liver disorders, or diabetes, have a cardiac pacemaker, or are pregnant, measurements made with this instrument should only be evaluated after consultation with your doctor.

• Take care while handling the batteries in the device. Incorrect usage may cause battery fluid leakage.

To prevent such accidents, refer to the following instructions:

— Insert batteries with the correct polarity.

— Turn off power after use. Remove and store the batteries if you are not planning to use the device for an extended period of time.

— Do not mix different types, brands, or size of batteries. This may cause damage to the product.

— Do not mix old and new batteries.

— Remove batteries and dispose of them according to the proper regulations in your area.

— Do not disassemble batteries or expose them to heat or fire.

— Do not short-circuit the batteries.

— Do not use rechargeable batteries.

1.2B Care of the Device

For prolonged life of your blood pressure monitor, note the following instructions:

• Do not drop or bang the unit. Prevent sudden jerks, jars, or shocks to the device to prevent damage.

• Do not insert any foreign objects in any device openings or vents.

• Do not disassemble the unit.

• If the unit has been stored at very low or freezing temperatures, allow to reach room temperature before using it.

• Do not store the unit in direct sunlight, high humidity, or in places with a lot of dust.

• Clean the device with a soft dry cloth. Do not use gasoline, thinner or similar solvents. Carefully remove spots on the cuff with a damp cloth and soap. Do not wash the cuff.

1.3 About Blood Pressure

Your blood pressure level is determined in the circulatory center of your brain. Your nervous system allows your body to adapt or alter blood pressure in response to different situations. Your body alters your pulse or heart rate and the width of blood vessels through changes in muscles in the walls of blood vessels.

Your blood pressure reading is highest when your heart pumps or ejects blood. This stage is called your systolic blood pressure.

Your blood pressure is lowest when the heart rests (in-between beats). This is called your diastolic blood pressure.

It is critical to maintain blood pressure values within a “normal” range in order to prevent cardiovascular diseases.

Increased blood pressure values (various forms of hypertension) have associated long and medium term health risks. These risks concern the arterial blood vessels of your body, which are endangered due to constriction caused by deposits in the vessel walls (arteriosclerosis). A deficient supply of blood to important organs (heart, brain, muscles) can be the result. Furthermore, with long-term increased blood pressure values, the heart will become structurally damaged.

There are many different causes of the appearance of high blood pressure. We differentiate between common primary (essential) hypertension, and secondary hypertension. The latter group can be ascribed to specific organic malfunctions. Please consult your doctor for information about the possible origins of your own increased blood pressure values.

1.4 Normal Blood Pressure Values

Blood pressure is too high when, at rest, the diastolic pressure is above 90 mmHg or the systolic blood pressure is over 140 mmHg.

If you obtain readings in this range, consult your doctor immediately. High blood pressure values over time can damage blood vessels, vital organs such as the kidney, and your heart.

Should the systolic blood pressure values lie between 140 mmHg and 160 mmHg or the diastolic blood pressure values lie between 90 mmHg and 95 mmHg, consult your doctor. Regular self-checks will be necessary.

With blood pressure values that are too low (i.e., systolic values under 105 mmHg or diastolic values under

60 mmHg), consult with your doctor.

Even with normal blood pressure values, a regular self-check with your blood pressure monitor is recommended.

This way you can detect possible changes in your values early and react appropriately.

Refer to the following table for classifying blood pressure values (units: mmHg) according to the World Health

Organization (WHO):




High Normal


• Stage 1: Mild

• Stage 2: Moderate

• Stage 3: Severe

Isolated Systolic Hypertension

Systolic Blood Pressure

< 120

< 130

130 - 139

140 - 159

160 - 179

> 180

> 140

Diastolic Blood Pressure

< 80

< 85

85 - 89

90 - 99

100 - 109

> 110

< 90

Important for Canadians: The Canadian Hypertension Education Program (CHEP) recommends that patients with average measurements of 135mmHg (systolic) or 85mgHg (diastolic) at home be considered hypertensive. Should your average readings be in this range, consult your physician.

For further information, see our website

Further information

If your values are mostly “normal” under resting conditions but exceptionally high under conditions of physical or psychological stress, it is possible that you are suffering from so-called ”labile hypertension”. In any case, please discuss the values with your doctor.

Correctly measured diastolic blood-pressure values above 120mmHg require immediate medical treatment.

1.5 Common Blood Pressure Questions and Answers


Why is my blood pressure reading always different?

Your blood pressure changes constantly. It is quite normal for blood pressure to fluctuate significantly (50 mmHg

to 60 mmHg) throughout the day. Blood pressure is normally lowest at night, but increases during waking hours

when the stress and activities of everyday life are highest.


AM Time PM

Your blood pressure also increases and decreases under the following circumstances

Blood pressure is higher than normal:

• when you are excited, nervous, or tense

• while taking a bath

• during and after exercise or strenuous physical activity

• when it is cold

• within one hour after meals

• after drinking tea, coffee, or other caffeinated drinks

• after smoking tobacco

• when your bladder is full

Blood pressure is lower than normal:

• after consuming alcohol

• after taking a bath


Why is the doctor’s reading different from the reading taken at home?

Your blood pressure can vary due to the environment (temperature, nervous condition). When measuring

blood pressure at the doctor’s office, it is possible for blood pressure to increase due to anxiety and tension.


Why should I monitor blood pressure at home?

One or two readings will not provide a true indication of your normal blood pressure. It is important to take

regular, daily measurements and to keep records over a period of time. This information can be used to

assist your physician in diagnosing and preventing potential health problems.

1.6 About MAM Technology

(Average Mode) technology is a new technology that enables optimum reliability in self-measurement of blood pressure.

An advanced measurement accuracy is achieved by the automatic analysis of three successive measurements, with short rest periods in between (see diagram 1).

This new technology provides reliable values for the doctor and can be used as the basis for reliable diagnostics and medication therapy for high blood pressure.

• Reliable patient self-measurement data for the doctor

• Safe hypertension diagnostic tool

• Reliable therapy control

1.6A Why Use MAM?

Human blood pressure is not stable

1.6B Key Advantages

The technology provides reduction in:

• Device scattering

• Insufficient rest prior to measurement

• Movement effects (i.e. coughing, talking, movement)

• Cuff positioning influences

1.6C Medical Benefits

Improved accuracy

1.6D Measurement Sequence

1.7 Important facts about atrial fibrillation (AFIB)

1.7A What is Atrial Fibrillation (AFIB)?

Normally, your heart contracts and relaxes to a regular beat. Certain cells in your heart produce electrical signals that cause the heart to contract and pump blood. Atrial fibrillation occurs when rapid, disorganized electrical signals are present in the heart’s two upper chambers, called the atria; causing them to contract quickly and irregularly (this is called fibrillation). Atrial fibrillation is the most common form of heart arrhythmia or irregular heart beat. You can live with atrial fibrillation, but it can lead to other rhythm problems, chronic fatigue, heart failure and - worst of all - a stroke. You’ll need a doctor to help you control the problem.

1.7B How does AFIB impact my family or me?

One in every six strokes is AFIB-related. While individuals above the age of 65 are more likely to have AFIB, individuals as young as 40 can exhibit AFIB. Early diagnosis can help reduce the risk of a stroke.

1.7C AFIB detection provides a convenient way to screen for AFIB (only in MAM mode)

Knowing your blood pressure and knowing whether or not you or your family members have AFIB can help reduce the risk of stroke. AFIB detection provides a convenient way to screen for AFIB while taking your blood pressure.

1.7D Risk factors you can control

High blood pressure and AFIB are both considered «controllable» risk factors for strokes. Knowing your blood pressure and knowing whether or not you have AFIB is the first step in proactive stroke prevention.

This section describes how to get the maximum benefit from your 3MS1-4K blood pressure monitor. Follow the instructions carefully to get an accurate measurement of your blood pressure and pulse rate.

3.1 Setting the Time and Date

When you insert the batteries for the first time (see “Inserting the batteries”), the monitor prompts you to set the current date and time. You can also adjust the date and time by pressing and holding down the button for over 3 seconds. Follow these steps to set the date and time settings:

1. When you press the button for over 3 seconds, the year will start flashing. Press the

button to adjust the year and press the button to confirm setting.


2. Next, the screen starts flashing the month setting. Press the button repeatedly to set the month and then press the button to confirm the settings. Follow the same steps to set the date setting.

3. Lastly, the screen starts flashing the hour values. Press the button repeatedly to set the hour and then press the button to confirm the settings. Follow the same steps to set the minute values.


3.2 Measurement Mode Selection (MAM or single)

Clinical studies demonstrate taking multiple blood pressure readings and calculating an “average” is more likely to determine your true blood pressure. Your premium blood pressure unit allows you to switch the unit to an Average

Mode setting that automatically takes multiple readings!

Average Mode Slide Switch (MAM): a) If you would like to take an Average Mode measurement, move the slide switch to the right. b) Average Mode takes 3 measurements in succession and calculates the result and displays it as a single average measurement. A

Average Mode.

symbol in the display indicates that the unit is set to the c) There will be 15 seconds resting time in-between each measurement. The unit will count down from 15 seconds.

A beep will sound at the last 5 seconds to remind you that the unit is about to take another measurement.

If one of the measurements causes an error message, it will be repeated one more time. If any additional error occurs the measurement will be discontinued and error code displayed.

Note: AFIB detection can only be done in MAM mode.

Single mode

a) If you would like to take a single mode measurement, please move the slide switch to the left. b) Single mode only has 1 measurement.

3.3 Obtaining Accurate Measurements

Your blood pressure can vary based on numerous factors, physiological conditions, and your surroundings. Follow these guidelines to obtain accurate and error-free measurements of your blood pressure and pulse rate.

3.3A Before Measuring

• Avoid eating, smoking as well as all forms of exertion directly before the measurement. All these factors influence the measurement result. Relax by sitting in an armchair in a quiet atmosphere for about 5 minutes before the measurement.

• Always take measurements on the same arm (normally left) and in the same posture. Do not switch between right and left arms while recording your blood pressure as there may be a difference of up to 10mmHg pressure between the two arms.

• Attempt to carry out the measurements regularly at the same time of day, since blood pressure changes during the course of the day. The ideal time to measure your blood pressure is in the morning after you wake up, before breakfast and physical activity, and in the absence of the urge to urinate.

• Rest for 5 minutes sitting quietly and release all the tension in your body — especially the arm muscles — before beginning with the measurement. Remain calm and quiet when the measurement is in process. Do not speak or move your arm (as well as other body) muscles during the process.

3.3B Common Sources of Error

All efforts by the patient to support the arm can increase the blood pressure. Make sure you are in a comfortable, relaxed position and do not activate any of the muscles in the measurement arm during the measurement. Use a cushion for support if necessary.


Comparable blood pressure measurements always require the same conditions with a peaceful and calm environment. Ensure that you take measurements under the same conditions to obtain an accurate estimate of blood pressure variation patterns.

• If the arm artery lies considerably lower or higher than the heart, an erroneous value of blood pressure is measured. Each 15 cm difference in height results in a measurement error of 10 mmHg.

• A loose cuff causes false measurement values.

• With repeated measurements, blood accumulates in the arm, which can lead to false results. Consecutive blood pressure measurements should be repeated after at least a 15 second pause or after the arm has been held up in order to allow the accumulated blood to flow away.

3.3C Fitting the Wide Range Cuff

a) Put the end of the cuff (with fastener) through the metal ring, making the cuff a cylinder. (Ignore this step if your cuff is already set up.) Proper assembly allows the Velcro


to match up properly.

a) b) Place the cuff around your arm. Make sure the bottom edge of the cuff is about 1” above the elbow joint. Adjust the cuff so that the rubber tubing under the cuff lies over the brachial artery, which runs on the inside of the arm (see Fig. C).

c) Pull the cuff and tighten it by attaching the Velcro



Normally, the left arm is used, unless there is a physical reason for using the right arm.

b) c) d) The cuff should fit snugly around the arm, but not too tight. You should be able to fit two fingers under the cuff.

e) Place the arm on the table (palm facing upwards) so that the cuff is at the same level as the heart. Make sure there is no kink in the hose.

d) e)

f) You can adjust the level of your arm by putting a cushion under your arm.

f) g) Remain seated in a comfortable room temperature for at least 5 minutes, then start the measurement. h) For those who cannot put the cuff on the left arm, put it on the right arm as shown.

g) h) i) Consecutive measurements will cause blood accumulation in the lower arm which will affect the measuring results. To improve reading accuracy, raise the arm being measured, squeeze and relax your hand several times, then take another measurement. Another option is to take the cuff off and wait at least 10 minutes before repeating measurement.

j) If this device was stored in low temperature, it is necessary to leave it in room temperature for at least 1 hour, otherwise the measurement can be inaccurate.


If it is not possible to fit the cuff to your left arm, it can also be placed on the right arm. However all measurements should be made using the same arm.

Comparable blood pressure measurements always require the same conditions

(Relax for several minutes before taking a measurement).


ATTENTION: Do not use cuff other than the original cuff contained in this kit!

3.4 Measuring Your Blood Pressure

After following the guidelines described in the previous section and placing the cuff around your upper arm, you are now ready to measure your blood pressure. Follow these steps to record your measurement.

1. Press the button to turn on the device and start measurement. The LCD screen is turned on. The cuff begins to inflate while the increasing cuff pressure is displayed on the screen. After the suitable inflation pressure is reached, the cuff stops inflating and the pressure gradually falls. A long beep sounds when the measurement is completed.

The systolic and diastolic blood pressure values along with the pulse rate are displayed on the screen. The measurement is displayed for approximately 1 minute.

2. Switch off the device by pressing the button to preserve the batteries. If no button is pressed for 1 minute, the instrument switches the display off.

NOTE: The time will continuously be displayed on the screen.

3.5 Appearance of the Atrial Fibrillation Indicator (only in MAM mode)

This symbol indicates that atrial fibrillation was detected during the measurement. If AFIB is present during blood pressure measurement, the AFIB Indicator is displayed. The AFib will flash 8 times rapidly once the measurement is complete and then stop flashing. In this case, the result may deviate from your normal blood pressure. It is highly recommended to take an additional measurement an hour later to increase the specificity of the detection. In most cases, this is no cause for concern. However, if the symbol appears on a regular basis (e.g. several times a week with measurements taken daily) we advise you to visit your doctor. Please, provide the following explanation:

Information for the doctor on frequent appearance of the atrial fibrillation indicator

This instrument is an oscillometric blood pressure monitor that also analyses pulse frequency during measurement.

The instrument is clinically tested.

The symbol is displayed after the measurement, if atrial fibrillation occurs during measurement. If the symbol appears more frequently (e.g. several times per week on measurements performed daily) we recommend the patient to seek medical advice. The instrument does not replace a cardiac examination, but serves to detect atrial fibrillation at an early stage.

• Sometimes the device will detect atrial fibrillation even when it is not there. This can happen if the arm moves during the reading or another rhythm problem is present. Keep the arm still during the reading. Visiting your doctor with this device may be necessary to check out any rhythm problems.

• This device may not detect atrial fibrillation in people with pacemakers or defibrillators.

3.6 Viewing Previously Recorded Values

The blood pressure monitor automatically stores your measurements. It can store up to 200 measurements. When more than 200 measurements are made, the oldest readings are deleted to make space for the new ones.

To view the previously stored values, press the button. The last measurement is displayed. The date and time of the measurement are also displayed after the reading. Press the button repeatedly to view all the measurements that are recorded on the device.

Note: Blood pressure measurements are not stored when an error is encountered during measurement.

3.7 Clearing All Values

If you are sure that you want to permanently remove all stored values, hold down the button (the instrument must have been switched off before hand) until the “CL” appears and then release the button. If you do not want to clear the values, press the button. To permanently clear the memory, press the button while “CL” is flashing. Individual values cannot be cleared.

3.8 Discontinuing a Measurement

If it is necessary to interrupt a blood pressure measurement for any reason (e.g. the patient feels unwell), the button can be pressed at any time. The device then immediately lowers the cuff pressure automatically.

4. Software Functions

This unit can be used in connection with your personal computer (PC) running the PC Link Blood Pressure Analyzer

Software. The software will allow a capacity of monitoring 80 patients, each with 1000 data (Note: overuse will lower system efficiency). The memory data can be transferred to the PC by connecting the monitor via USB cable with your

If problems occur when using the device the following points should be checked, and if necessary, the corresponding measures should be taken.


The display remains empty when the device is switched on. The batteries are inserted.

The pressure does not rise even though the pump is running.

The device frequently fails to measure the blood pressure values, or the values measured are too low or too high.

Every measurement produces varying results although the instrument functions normally and the values displayed are normal.

Blood pressure values measured differ from those measured by the doctor.


1. Check batteries for correct polarity.

2. If the display is unusual, re-insert the batteries or exchange them for new ones.

Check the connection of the cuff tube and connect properly if necessary.

1. Check the positioning of the cuff.

2. Measure the blood pressure again, ensuring that you have remained motionless for a sufficient amount of time to ensure an accurate reading.

Note that blood pressure fluctuates continuously; therefore measurements will show some variability.

Record the daily developement of the values and consult your doctor.

Note: Individuals visiting their doctor frequently experience anxiety which can result in a higher blood pressure reading than at home.

6. Care and Maintenance

a) Do not expose the device to either extreme temperatures, humidity, dust or direct sunlight.

b) The cuff contains a sensitive air-tight bubble. Handle this carefully and avoid all types of stress through twisting or buckling.

c) Clean the device with a soft, dry cloth. Do not use gas, thinners or similar solvents. Spots on the cuff can be removed carefully with a damp cloth and soapsuds. The cuff with bladder must not be washed in a dishwasher,
