Before using the BD401, please read this instruction manual carefully and keep it in 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™Talking Wrist Blood Pressure Monitor.
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.
• 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.

• 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.
• This device is intended for adult use only.
2. About 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. 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.
• 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. 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.
• 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
3

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.
2.1 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):
Category Systolic Blood Pressure Diastolic Blood Pressure
Optimal < 120 < 80
Normal < 130 < 85
High Normal 130 - 139 85 - 89
Hypertension
• Stage 1: Mild
• Stage 2: Moderate
• Stage 3: Severe
140 - 159
160 - 179
> 180
90 - 99
100 - 109
> 110
Isolated Systolic Hypertension > 140 < 90

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.
2.2 Common Blood Pressure Questions and Answers
a) Why is my blood pressure reading always different?
Your blood pressure changes constantly. It is quite normal for blood pressure to fluctuate
significantly(50mmHgto60mmHg)throughouttheday.Bloodpressureisnormallylowest
at night, but increases during waking hours when the stress and activities of everyday
life are highest.
mmHg
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
5

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.
2.3 What is mean arterial pressure (MAP)?
The mean arterial pressure (MAP) is the average pressure that forces blood through the
arteries. It is not the average of the systolic and diastolic blood pressure; rather, MAP
corresponds to a state of balance between the compressive and expansive forces acting
on the arterial wall when there is no distension outward or inward. MAP is an excellent
way to evaluate the stress on the walls of your blood vessels, and can be used to evaluate
excessive load on the cardiovascular system. Show your MAP history to your doctor to
provide additional information that may help him or her understand your situation.

4.2 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.
4.2A 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 wrist (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 wrist.
• 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.
• 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.
• Do not lean backward or bend your wrist inward while taking a measurement.
4.2B Fitting the wrist
a) Remove all accessories (watch, bracelet, etc.) from
your left wrist. If your physician has diagnosed you
with poor circulation in your left arm, use your right
wrist.
b) Roll or push up your sleeve to expose the skin.
c) Apply the cuff to your left wrist with your palm
facing up and the LCD display facing you.
11

d) Position the edge of the cuff about 0.4 inches (1cm)
from the bottom of your palm.
e) Fasten the wrist cuff around your wrist, leaving no extra room
between the cuff and your skin. If the cuff is too loose, the
measurement will not be accurate.
NOTE: Graphics may not exactly match product
4.2C Choose your measurement position
1. Choose the position from which you wish
to measure - sitting or lying down.
2. Position your body so that your wrist is
parallel with your heart, using the chart
and illustrations below as a guide.
