Designated Use
This unit uses an oscillometric measurement method in
order to measure systolic and diastolic blood pressure, as
well as the heart rate.
The measurement is conducted on the upper arm.
All values can be read on an LCD screen.
This unit has been developed for home and professional
use and should only be used by adults over 18 years of age
with an arm diameter of 22 ~ 32 cm / 8.7 - 12.6 inches.

Precautions
• This manual and the product are not substitutes for
visiting the doctor.
Neither the information contained herein nor this prod-
uct may be used to diagnose or treat health problems,
or to prescribe drugs. If you have or suspect that you
have a medical problem, please seek immediate advice from your doctor.
• Do not conduct any measurements if the temperature
is low (below +5 °C) or high (over +40 °C), or if the
relative humidity is beyond the range of 15 % to 90 %,
as this can lead to inaccurate readings.
• Wait 30 to 45 minutes, before taking a measurement if
you have just had a caffeinated drink or a cigarette.
• Relax for at least 5 to 10 minutes before taking a
measurement.
• Please wait 3 to 5 minutes between measurements,
so that your blood vessels can return to the state they
were in prior to measurement. You may have to adapt
the waiting time to your personal physiology.
• It is recommended that you use the same arm for each
measurement (preferably the left) and take the measurement at about the same time every day.
• Sit down comfortably with your elbows placed on the
table and both feet on the ground. Please do not interlock your legs during the measurement.
• Place the unit at the level of the heart. Relax your
hand. Your palm should be facing up.
• Take the measurement at room temperature in a quiet
and stress-free environment.
• The unit should not be moved or shaken during the
measurement. Please do not speak during the measurement.
• Please keep in mind that blood pressure naturally
varies depending on the time of day and is affected
by many different factors. Blood pressure is usually
highest at work and reaches its lowest level during the
sleep phase.
• Blood pressure measurements should be assessed
by a doctor or trained healthcare professional who is
familiar with your medical history. If you use the unit
and regularly record the results, please keep your
doctor informed with regard to the ongoing changes
in your blood pressure.
• If you suffer from a cardiovascular disease (such as
atherosclerosis), diabetes, a liver or kidney disease,

Precautions
severe hypertension or peripheral circulatory disorders, etc., please consult your doctor before using this
unit.
• The performance of this device can be infl uenced as
severe arrhythmias such as atrial or ventricular premature beats or atrial fi brillation are presented during
measurement.
• The blood pressure measurements conducted with
this unit are equivalent to measurements obtained
by a trained observer in accordance with the values
achieved using the cuff/stethoscope auscultation
method and are within the specifi ed EN 1060-4 stand-
ard limits.
• If the cuff causes any discomfort during the measurement, press the “POWER” button to turn off the unit
immediately.
• If the pressure is over 300 mmHg and the cuff does
not defl ate automatically, pull off the Velcro strap to
detach the cuff.
• Do not use this appliance on infants, children or persons who cannot express their own intentions.
• To avoid accidental strangulation, keep the product
away from children and do not place the hose around
the neck.
• Measuring too frequently may result in circulatory dis-
GB
orders, which can cause unpleasant sensations such
as localised bleeding under the skin or temporary
numbness in your arm. These symptoms do not usually last long. However, if you have not recovered after
some time, please consult your doctor.
• Please take into consideration the electromagnetic
compatibility of the unit (e.g. disruptions to the power
supply, radio frequency interference, etc.) see annex.
Please only use the unit indoors. To avoid inaccurate
results due to electromagnetic interference between
electrical and electronic equipment, please do not use
the unit near mobile phones or microwave ovens. In
the case of devices whose maximum power exceeds
2 W, the minimum distance from your blood pressure
monitor should be 3.3 metres.
• The unit is not waterproof. Never immerse this instrument in any liquids.
• Do not use the instrument if you think it is damaged or
if you notice anything unusual.

Information you should know
before operating the unit
What is blood pressure?
A force is created by the heart as the ventricle forcibly
ejects blood into the blood vessels and through the transport system. Another force is created by the arteries as they
resist the blood fl ow. Blood pressure is the result of these
two forces.
What are systolic and diastolic pressures?
Systolic pressure represents the highest pressure at the
height of the heart‘s contraction. Diastolic pressure is the
lowest pressure when the heart is resting.
Is my blood pressure normal?
See the following blood pressure classifi cation chart re-
leased by the WHO (World Health Organization) for evaluation of your blood pressure level.

Severe hypertension (Grade 3)
Moderate Hypertension (Grade 2)
Mild Hypertension (Grade 1)

What about low blood pressure?
In general, a lower blood pressure reading is better unless
it causes some uncomfortable symptoms such as fainting
and/or lightheadedness.
