8. Press the START/STOP button to turn off the device.
If you forget to turn off the device, it will do so automatically after 3 minutes.
Indication of Reliability
Important aspects in measuring the blood pressure imply the correct
application of the cuff and proper posture during the measurement. These aspects
may infl uence the measurement result. The device displays the symbol «
the measurement procedure is carried out properly. If this symbol is not displayed,
it is recommended to repeat the measurement observing the guidelines for proper
measurement described in this manual.
Do not perform several measurements in a row.
This will cause numbing the arm and can aff ect the measurement result. Give your
arm a break for at least 5 minutes.
INDICATION OF ARRHYTHMIA
The fl ashing symbol « », appeared on the
display reports on an irregular heartbeat rhythm
(Fig. 16). If this symbol appears from time to
time, refer to your doctor. The arrhythmia
indicator occurrence can be also caused by body
movements in the course of the measurement.
INDICATION OF READINGS BY THE WHO SCALE
In addition to pressure numerical values, the
result is also displayed as a graphic scale. This
scale makes it possible to classify the obtained
blood pressure value in accordance with the
World Health Organization recommendations.
The scale appears along with the numerical
value of blood pressure in the lower right corner
of the display (Fig. 17).

Indication of Pulse Pressure
This device calculates and displays the pulse
pressure value (Fig. 18). Pulse pressure – a dif-
ference between the systolic and diastolic pres-
sures – tends to increase with aging.
Systolic blood pressure continues to increase
with aging, while diastolic blood pressure tends
to decrease since the age of about 50 years.
It is considered that a high pulse pressure is re-
lated to poor elasticity of arteries and is one of the risk factors for circulatory diseases.
Pulse pressure is considered to be normal when it attains 35±10 mm Hg.
MEMORY FUNCTOIN
The measured values are automatically saved for later viewing in the selected memory
unit. These memory units can be used to save separately the measurement results
of two diff erent persons or to save separately the results of morning and evening
measurements.
Each unit can keep up to 60 measurement results and the average value thereof.
When the number of kept values exceeds 60, the oldest readings are deleted to
record new values.
