1. Introduction
Thank you for purchasing the Be Better Automatic Wrist Blood Pressure Monitor.
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
This device uses oscillometric technology to measure the arterial blood pressure
and pulse rate. The cuff is wrapped around the wrist and is automatically inflated
by the air pump. The sensor in the device senses weak fluctuation of the pressure
in the cuff produced by extension and contraction of the artery of the wrist in
response to each heartbeat. The amplitude of the pressure waves is measured,
converted to millimeters of the mercury column, and is shown on the display.
• Memory Features 1 user, 90 blood pressure readings with time and date
• Hypertension Classification Indicator displays the range between
which your blood pressure values lie, according to the WHO (World Health
Organization).
• Averages last 3 readings
• Time and date
• Detects irregular heartbeat

Before using this device, 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 Be Better Automatic 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.
• 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
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.

• 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.
2. 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.

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 120 mmHg 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 (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
mmHg

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

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.
