1. Introduction
Thank you for purchasing the BIOS Diagnostics™ Blood Pressure Monitor -
Simplicity. 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.
Indications for Use:
This blood pressure monitor (BD313) is intended to measure the systolic/diastolic
pressure, and pulse rate of an adult individual by using a non-invasive oscillometric
technology. This device is designed to be portable, and used in both home and
professional environments for every day blood pressure monitoring.
1.1 Features
The BD313 uses oscillometric technology to measure the arterial blood pressure
and pulse rate. The cuff is wrapped around the arm and automatically inated
by the air pump. The device senses weak uctuations of pressure within the cuff
produced by the extension and contraction of the arm’s artery in response to
each heartbeat. The amplitude of the pressure waves is measured, converted in
millimeters of the mercury column, and is shown on the display.
• Memory Features 30 blood pressure readings with time and date.
• BP Assessment Indicator displays the range between which your blood
pressure values lie, according to Hypertension Canada.
• Detects Irregular Heartbeat
• Averaging - Averages all stored readings
• Time and Date
This device is easy to use and has been proven in clinical studies to provide
excellent accuracy. Before using the BD313, read this instruction manual carefully
and keep it in a safe place.
The blood pressure monitor meets the accuracy requirements of Hypertension
Canada and has been tested for clinical accuracy.

1.2 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 mmHg): Recently, several studies have
identied 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 uid 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 re.
— Do not short-circuit the batteries.
— Do not use rechargeable batteries.
1.3 What do your Numbers Mean?
Blood pressure is the pressure in your blood vessels while blood circulates
throughout your body. High blood pressure or “Hypertension” is the pressure at
which ones normal average blood pressure is considered too high and other health
risks including: heart attack, stroke, dementia, kidney failure, heart disease and
erectile dysfunction may occur. It is expressed as two numbers: systolic/diastolic
120 mmHg/ 80 mmHg (mmHg= millimeters of mercury). “Systolic” numbers refer
to the pressure on the walls of your arteries while the heart is contracting and
pushing blood. “Diastolic” pressure is the lower number when the heart is at rest
and relaxed. A simple way to understand this is to picture a garden hose. When the
tap is turned on, the immediate pressure on the walls of the hose is the “systolic”
number, and when the tap is turned off it is the “diastolic” number.
There are many different causes of high blood pressure. We differentiate between
common primary (essential) hypertension, and secondary hypertension. The latter
group can be ascribed to specic 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
When rested, and measuring your blood pressure at home, measurements with
diastolic pressure readings above 85 mmHg or systolic readings over 135 mmHg
are considered high. If you obtain consistent 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.
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.
Systolic Diastolic Comment
Below 120 Less than 80 This range is considered “Normal” and ideal.
120 - 139 80 - 89
This range is considered “Pre-hypertension”.
Discuss with your health care professional.
Lifestyle modications maybe required to avoid
advancing into Hypertension.
140 - 159 90 - 99
This is in the hypertension range. Discuss with
your health care professional. Medication(s) and
lifestyle modications are typical treatments.
160 and
higher 100 +
Discuss with your medical professional,
medication(s) and lifestyle modications are
necessary to control your hypertension.
Adopted From: Understanding and Managing your blood pressure;
Hypertension Canada.
Note: A diagnosis of high blood pressure must be confirmed with a
medical professional. A doctor should evaluate any unusual blood
pressure readings. Additionally, lower targets may be appropriate for
some populations such as African-Americans, the elderly, or patients with
underlying issues such as diabetes mellitus or chronic kidney disease.

Important for Canadians:
* Hypertension measured at home ≥ 135/85
* Hypertension measured at a physician’s office ≥ 140/ 90
* Hypertension measured at a physician’s office for a diabetic patient ≥
130/80

3.2 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.
3.2A Tips on Taking Accurate Measurements
In the morning before
breakfast, 2 hours after dinner,
before taking medication.
Avoid coffee and smoking within
the hour, and no exercise 30
minutes before measuring.
Do not speak while taking the
measurement.
Sit with legs uncrossed so as
not to restrict blood ow.
Empty bladder (if necessary).
Rest quietly for 5 minutes.
Remain calm and quiet while the
measurement is in process.
Take measurements on the non
dominant arm.
Sit with back supported and
measurement arm resting on a
table. Sit with feet at on the oor.
Ensure that the cuff is level
with the heart while the arm is
supported on the table.
3.2B 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 calm environment.
Ensure that you take measurements under the same
conditions to obtain an accurate and reliable readings.
• 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 45 second pause or after the arm has been held up in order to
allow the accumulated blood to ow away.
3.2C Fitting the Wide Range Cuff
NOTE: Visit www.biosmedical.com for a video that illustrates how to properly t the
cuff.
a) Putting the cuff velcro side down on a table,
the words on the cuff should be facing right
side up. 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. Measure on your non-
dominant arm, unless there is a >10 mmHg
difference with the other arm, in which case
use the arm with the higher pressure.
b) Place the cuff around your bare arm. Make
sure the bottom edge of the cuff is about 1”
(2-3 cm) 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. B). The red material
should be over the brachial artery.
b)
Metal Ring
a)

c) Pull the cuff and tighten it by attaching the
Velcro®fastener.
d) The cuff should t snugly around the bare arm,
but not too tight. You should be able to t two
ngers under the cuff. If the cuff is the wrong
size, the device will not measure your blood
pressure accurately. Contact the store, or BIOS
Medical for other sized cuffs.
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.
f) You can adjust the level of your arm by putting a
cushion under your arm. Ideally the cuff should
be at heart level.
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) More than 6 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 5
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:
Continue to use the same arm for comparisons. It is not unusual for there to be a
difference in blood pressure between arms. Initially, check BP on both arms. If one
arm is 10mmHg higher, continue to measure on that arm.
Comparable blood pressure measurements always require the same conditions
(Relax for several minutes before taking a measurement).
ATTENTION: Do not use a cuff other than the original cuff contained in this
kit!
3.3 Measuring Your Blood Pressure
After the cuff has been appropriately positioned, the measurement can begin.
1. Press the START/STOP button until all symbols appear on the screen. You will
hear 2 short beeps, and “ ” will ash on the screen for 2 seconds. The pump
then begins to inate the cuff. The increasing pressure in the cuff is shown on
the display.
2. After the suitable pressure has been reached, the pump stops and the cuff
gradually deates. The cuff pressure will then be displayed. In case the initial
ination is not sufcient, the device automatically re-inates to a higher
pressure.
3. When the device detects a heartbeat, the heart symbol “ ”on the display
starts to ash and you can hear a beep for every heartbeat.
4. When the measurement has been completed, you will hear a long beep and the
systolic, diastolic and pulse rate will appear on the display.
5. The measurement readings remain on the display until you switch off the
device. If no button is pressed, the device switches off itself in 3 minutes.
NOTE: The symbol “ ” will be displayed along with the reading if an irregular
heartbeat has been detected during the measurement. If the “ ” symbol appears
frequently (e.g. several times a week), it may be an indication of a more serious
heart problem, and you should consult your doctor.
3.4 Discontinuing a Measurement
To stop the measurement (eg. the patient feels unwell) press the START/STOP
button. The device will immediately decrease the cuff pressure automatically.

3.5 Determining Your “Real” Average Blood Pressure at Home
It is normal for blood pressure to vary signicantly in the middle of the day when
most people are busy with their daily tasks. Hypertension Canada recommends
measuring in the morning and evening to avoid variability.
At the end of a measurement, this instrument automatically stores each result,
including date and time.

This data can be used by a medical professional to make a diagnosis of
hypertension.
3.6 Memory Recall
This blood pressure monitor automatically stores 30 measurements in its memory.
The oldest record will be replaced by the latest measurement value when there are
more than 30 sets.
3.7 Recall the Memory with the Power Off
Press the MEM button, the average of all the measurements will be shown, you will
see “AV” on the bottom left hand side of the screen.
Press the MEM button for a second time to see the most recent measurement
value. Subsequent measurements can be displayed one after the other by pressing
the MEM button.
3.8 Clear Measurements From Memory
If you are sure that you want to permanently remove all stored memories, when the
power is off, press and hold the MEM button and then press it 5 times until “ ”

appears. Press the START/STOP button until
“ ” ashes 3 times to clear the memory. After this, press either the MEM button,
the symbols “ ” and
“ ” will appear on the screen. This means that the memory has successfully
cleared.
3.9 Blood Pressure Assessment Indicator
The bars on the left hand side of the display show you the range within which
the indicated blood pressure values lies. Depending on the height of the bar, the
readout value is either within the normal (green), borderline (yellow) or danger (red)
range.
The classication is based on standards adopted by Hypertension Canada. The
indicator bar rises according to your measurement.
• If your measurement has only one or two bars, your measurement is in the
green zone, or “Normal”.
• If your measurement has three
bars, it is in the yellow zone,
or “High Normal”, in the pre-
hypertensive range.
• If your measurement has four
bars, it is in the red zone “High
Blood Pressure with Self /
Home Monitoring”.
• If your measurement has
ve bars, it is in the red
zone or “Moderate to Severe
Hypertension”.
4. Blood Pressure FAQ
4.1 Common Blood Pressure Questions & Answers
a) Why is my blood pressure reading always different?
Your blood pressure changes constantly. It is quite normal for blood pressure to
uctuate as much as 50 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.

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 ofce, it is possible for
blood pressure to increase due to anxiety and tension, this is known as “White Coat
Hypertension”.
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.
4.2 Comparing Readings to Other Blood Pressure Devices
Many questions arise when two blood pressure devices are compared in an effort to
check accuracy. An accurate comparison requires repeatable measurements under
the same conditions to “reference device” with known accuracy. Signicant time is
required to reduce naturally occurring blood pressure variability during the test. The
subject should be seated comfortably with feet at on the oor, and have rested
for 5 minutes before the rst reading to allow blood pressure levels to stabilize.
The patients back, elbow and forearm should be supported, and the middle of the
cuff should be at the level of the right atrium. There should be no talking or moving
during the measurement and if comparing to an aneroid gauge or mercury column,
observers should avoid parallax and be careful not to round measurements.
The most accurate way to compare devices is to take two readings at the same
time. However, most people and doctor’s ofces do not have the equipment
necessary to measure blood pressure from two devices simultaneously. To take
sequential measurements properly requires a pair of initial measurements to
determine the subjects blood pressure level: rst with the reference equipment,
followed by 60 seconds, then with the monitor-under-test. The actual accuracy test

requires three pairs of measurements with 60 seconds between measurements.
These measurements are averaged and a comparison can be made. Since most
people tend to relax and their blood pressure falls with subsequent measurements,
following this protocol reduces these natural changes in Blood Pressure levels. The
standard technical error of both consumer and professional devices is normally
±3 mmHg, so a discrepancy of 6 mmHg is acceptable even when the devices are
working within their specications.
Any comparisons without a known “reference device” and not following the
procedures described above will yield unreliable results. In addition, to do an accuracy
test properly the reference device must also be tested to a known reference to
conrm its accuracy, prior to being used as the reference for comparisons.
5. Trouble Shooting
5.1. Error Messages / Malfunctions
If an error occurs during a measurement the LCD displays the corresponding error code.
Error Possible Cause Remedy
