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.

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.

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 www.biosdiagnostics.com.
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.

Blood pressure is lower than normal:
 •afterconsumingalcohol
 •aftertakingabath
b) 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.
c) 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

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.

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 symbol in the display indicates that the unit is set to the
Average Mode.
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

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.

ATTENTION!
Comparable blood pressure measurements always require the same conditions with a peaceful and

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

e)

f) You can adjust the level of your arm by putting a cushion under
your arm.
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.
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.
Comment:
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inatewhiletheincreasingcuffpressureisdisplayedon
thescreen.Afterthesuitableinationpressureisreached,thecuffstopsinating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ash8timesrapidlyonce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.

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.

5. Error Messages / Malfunctions
If an error occurs during a measurement, a long beep followed by two short beeps is generated and the LCD display
the corresponding error code.
Error Possible Cause Remedy
Err 1 No pulse has been detected. Ensure that the cuff is being worn correctly, and
that you have your arm at the heart level.
Err 2 Unnaturalpressureimpulsesinuencethemea-
surement result.Reason: The arm was moved
during the measurement.
Avoid unnecessary movement or talking.
Err 3 Theinationofthecufftakestoolong.Thecuff
is not correctly seated.
Ensure that the cuff is being worn correctly.

Err 5 The difference between systolic pressure and
diastolic pressure is too far away from accept-
able and reasonable range.
Ensure that the cuff is being worn correctly and
that you have been inactive for a sufficient time
before making the measurement.
Err 6 Due to unstable conditions during measure-
ments, it is not possible to calculate an average
result.
Avoid unnecessary movement and talking.
Low battery Replace batteries.

sure again.Avoid movement or talking when
thecuffisbeinginated.
Lo Pulse below 40 is detected. Ensure that the cuff is worn correctly.
If problems occur when using the device the following points should be checked, and if necessary, the
corresponding measures should be taken.
Malfunction Remedy
The display remains empty when the device is switched
on.The batteries are inserted.
1. Check batteries for correct polarity.
2. If the display is unusual, re-insert the batteries or
exchange them for new ones.
The pressure does not rise even though the pump is
running.
Check the connection of the cuff tube and connect
properly if necessary.
The device frequently fails to measure the blood
pressure values,or the values measured are too low
or too high.
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.
Every measurement produces varying results although
the instrument functions normally and the values
displayed are normal.
Notethatbloodpressureuctuatescontinuously;
therefore measurements will show some variability.
Blood pressure values measured differ from those
measured by the doctor.
Record the daily developement of the values and
consult your doctor.
Note: Individuals visiting their doctor fre-
quently experience anxiety which can result in
a higher blood pressure reading than at home.
