1. Introduction
1.1. Features of the WA-
55
Thank you for purchasing the B.Well upper arm blood pressure monitor WA-55. 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. High blood
pressure (hypertension) is a serious health problem that is frequently found in the modern world. 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 help your physician diagnose and prevent
any health problems in the future.
Features
The WA-55 is a fully automatic, digital, dual user, upper arm blood pressure measuring device with
a unique fuzzy logic technology and a convenient LCD screen with backlight. It can store up to 99
blood pressure readings.
It provides fast and reliable measurement of systolic and diastolic blood pressure as well as heart
rate using the oscillometric measurement method. This device is easy to use and has been proven in
clinical studies to provide excellent accuracy.
Before using the WA-55, read this instruction manual carefully and keep it in a safe place.
Attention!
1.2. Important information about self-measurement
Do not forget: self-measurement means Control, not diagnosis or treatment. Unusual values must
always be discussed with your doctor. Under no circumstances should you alter the dosages of
any drugs prescribed by your doctor.
The pulse display is not suitable for checking the frequency of heart pacemakers!
In cases of cardiac irregularity (Arrhythmia), measurements made with this instrument should only
In cases of cardiac irregularity (Arrhythmia), measurements made with this instrument should only
be evaluated after consultation with the doctor.
Electromagnetic interference
The device contains sensitive electronic components (Microcomputer). Therefore, avoid strong elec-
trical or electromagnetic fields in the direct vicinity of the device (e.g. mobile telephones, microwave
cookers). These can lead to temporary impairment of the measuring accuracy.

2. Important information on the subject of blood-pressure and its measurement
2.1. How does high/low blood-pressure arise?
The level of blood-pressure is determined in a part of the brain, the so-called circulatory centre, and
adapted to the respective situation by way of feedback via the nervous system.
To adjust the blood-pressure, the strength and frequency of the heart (Pulse), as well as the width of
circulatory blood vessels is altered. The latter is effected by way of fine muscles in the blood-vessel
walls.
The level of arterial blood-pressure changes periodically during the heart activity: during the «blood
ejection» (Systole) the value is maximal (systolic blood-pressure value), at the end of the heart’s «rest
period» (Diastole) minimal (diastolic blood-pressure value).
The blood-pressure values must lie within certain normal ranges in order to prevent particular dis-
eases.
2.2. Which values are normal?
Blood pressure is too high if at rest, the diastolic pressure is above 90 mmHg and/or the systolic
blood-pressure is over 160 mmHg. In this case, please consult your doctor immediately. Long-term
values at this level endanger your health due to the associated advancing damage to the blood vessels
in your body.
Should the systolic blood-pressure values lie between 140 mmHg and 160 mmHg and/or the diastolic
blood-pressure values lie between 90 mmHg and 95 mmHg, likewise, please consult your doctor.
Furthermore, regular self-checks will be necessary.
With blood-pressure values that are too low, i.e. systolic values under 105 mmHg and/or diastolic
values under 60 mmHg, likewise, please consult your doctor.
Even with normal blood-pressure values, a regular self-check with your blood-pressure monitor is
recommended. In this way you can detect possible changes in your values early and react approp-
riately.
If you are undergoing medical treatment to control your blood pressure, please keep a record of the
level of your blood pressure by carrying out regular self-measurements at specific times of the day.
Show these values to your doctor. Never use the results of your measurements to alter independently
the drug doses prescribed by your doctor.

Blood-pressure
Measures
Hypotension
lower than 100
lower than 60
Check with your
doctor
Normal range

between 60 and 90
Self-check
Mild hypertension
between 140 and 160
between 90 and 100
Consult your doctor
Moderately serious
hypertension
between 160 and 180
between 100 and 110
Consult your doctor
Serious hypertension
higher than 180
higher than 110
Consult your doctor
immediately
Further information
If your values are mostly standard under resting conditions but exceptionally high under conditi-
ons of physical or psychological stress, it is possible that you are suffering from so-called «labile
hypertension». Please consult your doctor if you suspect that this might be the case.
Correctly measured diastolic blood-pressure values above 120 mmHg require immediate medical
treatment.
2.3. What can be done, if regular increased/low values are obtained?
a) Please consult your doctor.
b) Increased blood-pressure values (various forms of hypertension) are associated long- and medium
term with considerable risks to health. This concerns the arterial blood vessels of your body, which
are endangered due to constriction caused by deposits in the vessel walls (Arteriosclerosis). A de-
ficient supply of blood to important organs (heart, brain, muscles) can be the result. Furthermore,
with long-term continuously increased blood-pressure values, the heart will become structurally
damaged.
c) There are many different causes of the appearance of high blood pressure. We differentiate between
the 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.

d) There are measures which you can take, not only for reducing a medically established high blood
pressure, but also for prevention. These measures are part of your general way of life:
A) Eating habits
• Strive for a normal weight corresponding to your age. Reduce overweight!
• Avoid excessive consumption of common salt.
• Avoid fatty foods.
B) Previous illnesses
• Follow consistently any medical instructions for treating previous illness such as:
• diabetes (Diabetes mellitus)
• fat metabolism disorder
• gout
C) Habits
• Give up smoking completely
• Drink only moderate amounts of alcohol
• Restrict your caffeine consumption (Coffee)
D) Physical constitution
• After a preliminary medical examination, do regular sport.
• Choose sports which require stamina and avoid those which require strength.
• Avoid reaching the limit of your performance.
• With previous illnesses and/or an age of over 40 years, please consult your doctor before beginning
your sporting activities. He will advise you regarding the type and extent of types of sport that are
possible for you.

• No power is taken from the batteries while the mains adaptor is connected to the instrument.
Attention!
After the battery warning appears, the device is blocked until the batteries have been replaced.
Please use AA Long-Life or Alkaline 1.5V Batteries. The use of 1.2V Accumulators is not recom¬-
mended. If the blood-pressure monitor is left unused for long periods, please remove the batteries
from the device.Functional check: Hold on the
button down to test all the display elements. When
functioning correctly all segments must appear.
Using a mains adapter
