GENERAL INFORMATION
This Instruction Manual is designed to assist the user with safe and effective operation
of the automatic digital Device for measurement of blood pressure and heartbeat rate
LD, (modification LD12) (hereinafter – the “Device”). Use this Device according to the
rules described in this Manual. Operate the Device only as intended. Do not use the
Device for any other purposes. Read and understand the whole Instruction Manual, in
particular“Recommendations on Correct Measurement”.
INDICATIONS FOR USE
Use this Device to measure your systolic and diastolic blood pressure and
heartbeat rate in patients aged from 15. This Device is recommended for use by
persons with unstable blood pressure or known arterial hypertension at home
as an addition to medical surveillance. The cuff is designed for the wrist with the
circumference approximately from 12,5 to 20,5 cm.
OPERATION PRINCIPLE
This Device uses the oscillometric method of blood pressure with Fuzzy Algorithm
and pulse rate measurement. Wrap the cuff with an electronic unit around your
wrist. Press the button on the live monitor to automatically start inflating the
cuff and then while gradually deflating the cuff take its measurements. The sensi-
tive element of the Device feels the weak pressure oscillations in the cuff generated
by widening and contraction of the brachial artery in response to every heartbeat.
Pumping in is ceased when cuff is adequately pumped in to determine diastolic and
systolic pressure (the amplitude of the pressure waves is measured, converted into
millimeters Hg and shown on the display as figures) after which air is released from
cuff. The Device has Arrhythmia Indicator and 2 memories, by 90 cells, for storage of
measurement results with Average value of the last three measurements function.
Remember that the Device will not maintain the mentioned accuracy of a measure-
ment if it is used or stored at a temperature or humidity other than those specified
in Technical Specifications of this Manual. We are warning about possibility of mis-
takes in blood pressure measurement with this Device in persons with pronounced
cardiac arrhythmia. Consult the doctor concerning blood pressure measurement
of your child.

RECOMMENDATIONS ON CORRECT MEASUREMENTS
1. For correct measurement you should know that THE BLOOD PRESSURE IS
SUBJECT TO SHARP VARIATIONS EVEN WITHIN THE SHORT TIME INTERVALS. The
blood pressure depends on many factors. It is usually lower in summer and higher in
winter. The blood pressure varies together with the atmospheric pressure, depends
on physical loads, emotional excitement, stresses and dietary regime. Drugs, drink-
ing alcohol and smoking produce significant effect. Even the very procedure of
blood pressure measurement in a polyclinic sends the blood pressure high in many
people, thus, the blood pressure measured at home often differs from the values
received in a polyclinic. As the blood pressure tends to rise at low temperatures,
make measurements at an indoor temperature (approximately 20° C). If this Device
stayed under a low temperature, keep it for at least 1 hour at an indoor tempera-
ture before use, otherwise the measurement result may be incorrect. During a day
the difference in readings for healthy people may be 30-50 mmHg of systolic pres-
sure and to 10 mmHg of diastolic pressure. The dependence of the blood pressure
on various factors is individual for each person. Accordingly, it is recommended
to keep a special book with blood pressure records. ONLY A CERTIFIED DOCTOR
USING YOUR RECORDS IS CAPABLE TO ANALYZE THE TENDENCY OF YOUR BLOOD
PRESSURE VARIATIONS.

2. At cardiovascular and some other diseases requiring blood pressure moni-
toring make measurements in the hours fixed by your attending doctor.
REMEMBER THAT THE DIAGNOSTIC AND ANY TREATMENT OF HYPERTENSION
MAY BE CONDUCTED ONLY BY A CERTIFIED DOCTOR ON THE BASIS OF BLOOD
PRESSURE VALUES OBTAINED BY THIS DOCTOR. TAKING OF DRUGS AND THEIR
DOSES SHOULD BE PRESCRIBED ONLY BY YOUR ATTENDING DOCTOR.
3. At such disorders as deep vascular
sclerosis, weak pulse wave and also in
patients with the prominent distortions of
cardiac rhythm it may be difficult to measure
the blood pressure accurately.
IN SUCH CASES CONSULT A CERTIFIED
DOCTOR ABOUT APPLICATION OF THE
ELECTRONIC DEVICE.
4. KEEP QUIET DURING A MEASUREMENT
TO OBTAIN THE ACCURATE VALUES
OF YOUR BLOOD PRESSURE WITH THE
ELECTRONIC DEVICE. MEASURE YOUR
BLOOD PRESSURE IN THE CALM AND
COMFORTABLE CONDITIONS AT THE INDOOR TEMPERATURE. NO EATING
AN HOUR BEFORE MEASUREMENT; NO SMOKING, TAKING TONIC AGENTS,
ALCOHOL 1.52 HOURS BEFORE MEASUREMENT.
5. The accuracy of blood pressure measurement depends on whether the cuff
matches the size of your arm. THE CUFF SHOULD NOT BE TOO SMALL OR TOO
LARGE.
6. Wait 3 minutes between measurements for the blood to restore its circulation.
However, the persons with prominent atherosclerosis due to considerable loss
of vascular elasticity may need to increase the wait time between measurements
(10-15 minutes). This also refers to the patients suffering for long from diabetes .
For more accurate determination of blood pressure it is recommended to make a
series of 3 consecutive measurements and to use the average value .
7. The rate of wrist blood pressure may be different from that of the arm. If to
regard a healthy person, this variation may be specified within the range of +/-10
mm Hg for both the systolic and diastolic pressure. The persons to have such health
problems, as hypertension, diabetes, liver function abnormality, peripheral blood
flow etc. must be very careful. In this case, wrist and arm measurements may sub-
stantially vary.

If irregular pulse rhythm is detected during
measurement, symbol of arrhythmia “ ”, will appear
upon measurement end. Appearance of arrhythmia
indicator may also be caused by body movement during
measurement. During periodical appearance of this
indication apply to You attending doctor.
Apart from numerical value of pressure, result is also
displayed on scale WHO (fig. 10). Scale WHO – three-
color scale of classification of received value of arterial
pressure, according to recommendation of World Health
Organization. Using the scale on the left display field,
estimate your findings against the following classification:
blood pressure is normal; blood pressure is exceeded or
specific degree of arterial hypertension is detected.
6. Press to change to mode of date and time
indication. For taking a new measurement repeat
all steps described in this paragraph.
TO OBTAIN THE ACCURATE RESULT MAKE
INTERVAL BETWEEN MEASUREMENTS TO
RESTORE THE BLOOD CIRCULATION. WAIT FOR
AT LEAST 3 MINUTES BEFORE MAKING A NEW
MEASUREMENT.
Result of each measurement
(pressure, pulse) will kept in the device memory
automatically.
THE DATA WILL BE KEPT IN THE MEMORY EVEN IF THE DEVICE IS STORED WITHOUT
BATTERIES. TO DELETE ALL VALUES STORED IN THE MEMORY YOU SHOULD MAKE
ACTIONS DESCRIBED IN “MEMORY FUNCTION”.
If no actions are done in mode of date and time setting for more than 3 minute, the
Device is independently changed over to mode of date and time indication.
AUTOMATIC REINFLATION
When during the first blood pressure measurement the cuff inflation to a
level of 190 mmHg is not sufficient or you move your arm the Unit stops
measurement and re-inflates the cuff to the higher level. The Unit has 4 fixed
levels of the arm cuff inflation: 190, 230, 270 and 300 mmHg.
The automatic re-inflation is repeated until the measurement is completed
successfully. This is not a defect.
FORCED DEFLATION FROM A CUFF
For rapid air release from of the arm cuff during arm cuff inflation or during
a measurement (slow deflation) press the . Button. The device will quickly
release all air from cuff and will switch off.
