INSTRUCTION MANUAL
BM122 DIGITAL DEVICE FOR READING BLOOD PRESSURE
ON THE UPPER ARM
Dear Customer,
Please read this manual carefully before use in order to avoid damages resulting from misuse.
Please pay particular attention to the safety information.If you pass the device on to a third
party, these Operating Instructions must also be handed over.
BLOOD PRESSURE MEASUREMENT
This unit allows you to measure the systolic and diastolic blood pressure as well as the heartbeat
frequency oscillometrically. All readings can be read on the LCD display. This blood pressure
measurement unit is meant only for measuring on the upper arm of adults. It is for home use and
only for non-invasive blood pressure measuring. If the blood pressure is measured by a doctor in
the hospital, then the stress or other effects this may have on the patient can result in higher blood
pressure. Blood pressure is subject to constant change depending on circumstances. Therefore,
one should not draw conclusions from a single measurement. It is better to take measurements at
home and schedule regular readings. This will give you a more accurate knowledge of your actual
blood pressure and help your doctor to make important decisions for diagnosis or treatment. If you
are suffering from heart or liver problems, arterial deposition, diabetes, or similar problems, please
seek advice from your doctor before carrying out the measurements.
WHAT IS BLOOD PRESSURE?
Blood pressure is the pressure which the blood exerts to the arteries. The blood pressure inside
the arteries is always fluctuating during your heart cycle. The highest pressure during this cycle
is called systole and the lowest pressure is called diastole. With these two blood pressure
values, the systole and the diastole, the doctor can determine the blood pressure of the patient.
Your blood pressure can be influenced by many different factors, like physical effort, fear, the
time of day, etc. The blood pressure is usually low in the morning and increases in the afternoon
until the evening.It is generally lower in summer and higher in winter.

WHAT IS THE PURPOSE OF MEASURING YOUR BLOOD PRESSURE AT HOME?
Measuring blood pressure during a check-up by a doctor in a hospital or clinic can make a
person nervous, which results in a higher blood pressure. Various factors can influence a blood
pressure measurement, therefore one single measurement does not necessarily give an
accurate reading. The measured blood pressure of a relaxed patient, after getting up in the
morning and before eating breakfast, is called fundamental blood pressure. Therefore
measuring the blood pressure at home is important, because there the blood pressure is closest
to this status.
A. Classification of blood pressure according to WHO
The standards to measure high and low blood pressure,
regardless of age, were determined by the World Health
Organization (WHO), as shown in picture 1.
B. Fluctuations of blood pressure
Blood pressure fluctuates depending on the time of day and
season. The fluctuations are more marked in
people with high blood pressure. Normally
blood pressure is higher when one is working
and then lowers during the night. The
fluctuations of blood pressure during a day
are illustrated in picture 2. These
measurements were taken every 5 minutes.
The thick line represents the period of sleep.
The rise of the blood pressure at 4 o'clock in
the morning (shown in the illustration Fig. 2
as A) and at noon (shown in the illustration as
B) represent a pain attack.

POINTS TO NOTE BEFORE USING THE MEASURING INSTRUMENT UNIT
CAUTION!
Read the instructions carefully before using the device.
Please follow instructions carefully.
Do not use device near mobile phones and microwaves to avoid electromagnetic
disturbances.
• Blood pressure should be taken by a doctor or an expert who knows your medical history. By
making regular use of the blood pressure measuring unit and recording your readings, you
can keep your doctor informed of your blood pressure tendencies.
• Connect the tube with the appliance’s tube connector.
• Tie the sleeve securely around your upper arm. The sleeve should be at the same height as
your heart. If necessary, support the arm on a table by placing an object (e.g. a cushion)
underneath.
• The measuring instrument should not be moved or jostled during the measurement, because
this can lead to incorrect measurement of the blood pressure.
• Do the measurement in a quiet place and in a relaxed position without talking.
• Do not twist the seal around the sleeve of a jacket or a shirt, because it is not possible to get
an accurate measurement this way.
• Remember that the blood pressure fluctuates naturally during the daytime and other factors
such as smoking, drinking alcohol, bathing, taking medicine, and physical effort influence
blood pressure levels.
• The values of the blood pressure measurement available in this measuring appliance
correspond with the values of a trained specialist, who measures with a sleeve while listening
with a stethoscope. The measurement values are between the limit values which were
determined by the national standardization for electronic and automated
sphygmomanometers of the United States.
