GENERAL INFORMATION
This Instruction Manual is designed to assist the user with safe and effective
operation of the semiautomatic digital Device for measurement of blood pres-
sure and heartbeat rate LD,
( modification LD22 ( 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 under-
stand 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
upper arm with the circumference approximately from 25 to 36 cm.
OPERATION PRINCIPLE
This Device uses the oscillometric method of blood pressure with Fuzzy
Algorithm and pulse rate measurement. Wrap the cuff around your upper arm
and it starts to be inflated by bulb. The sensitive 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.
Remember that the Device will not maintain the mentioned accuracy of a
measurement 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 mistakes in blood pressure measurement with this Device
in persons with pronounced cardiac arrhythmia. Consult the doctor concerning
blood pressure measurement of your child.
APPLIED NEW LD TECHNOLOGIES
Fuzzy Algorithm – algorithm for processing the measurement
values with regard to peculiarities of the man’s heartbeat, thus,
ensuring high measurement accuracy.
WARNING! This Device may be used only with cuffs:
- Cuff-LDA, size 25-36 cm (delivered in a set with the Device).

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 pres-
sure, depends on physical loads, emotional excitement, stresses and dietary
regime. Drugs, drinking 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 (approxi-
mately 20° C). If this Device stayed under a low temperature, keep it for at least
1 hour at an indoor temperature 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 pressure and to 10 mmHg of diastolic pressure. The
dependence of the blood pressure on various factors is individual for each per-
son. Accordingly, it is recommended to keep a special book with blood pressure
records. ONLY A CERTIFIED DOCTOR USING YOUR RECORDS IS CAPABLE TO ANA-
LYZE THE TENDENCY OF YOUR BLOOD PRESSURE VARIATIONS.
2. At cardiovascular and some other diseases requiring blood pressure
monitoring 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 circula-
tion. However, the persons with prominent atherosclerosis due to consider-
able 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.
POWER SUPPLY OF THE DEVICE
1. Open the cover of the battery
compartment and install 4 “AA” size
batteries according to polarity marked
inside the compartment. Do not use much
force to remove the cover of the battery
compartment.
2. Close the battery cover.
Replace all batteries when the Low Battery Indicator “ ”, appears on the screen
or when there is no any indication on the screen. The Low Battery Indicator
does not show the discharge level
. Alkali batteries are recommended. When the
device operating rules are observed, the batteries serve for approximately 1000
measurements. The batteries supplied with the Device are intended for check of
the Device performance at sale and their service life may be shorter than of the
recommended batteries
. Replace all four batteries at the same time. Do not use
the waste batteries . If the Device is unused for a long time, remove all batteries .
Do not leave the waste batteries in the Device .
CORRECT POSITION DURING MEASUREMENT
1. Sit at a table so that during blood pressure
measurement your hand rests on its surface. Be sure
that the cuff is placed approximately at the level of
your heart and that your arm lies freely on the table
and does not move.

ENG
2. You can measure the blood pressure lying on
the back. Look at the ceiling, keep quiet and do
not move during measurement. Be sure that
the cuff is placed approximately at the level of
your heart .
CUFF PREPARATION
1. I nsert the cuff end for about 5 cm into a
metal ring as shown in the figure.
Fig.4
2. Apply the cuff to your left upper arm so
that the air tube is directed to your palm. If
the measurement on your left arm is difficult,
you may use your right arm. In this case
remember that the readings may differ by
5-10 mmHg and even more
.
Fig.5
3. Wrap the cuff around your upper arm so
that the bottom of the cuff is approximately
2-3 cm above your elbow. The sign “ARTERY”
should be over the arm artery.
Fig.6
4. Fix the cuff so that it fits tightly to the arm,
but see that it is not overtight. Too tight or too
free placement of the cuff may give inaccurate
readings.
Fig.7
5. On the fixed cuff the sign «INDEX» should point
to the area «NORMAL (25-36 cm)». It means that
the cuff is chosen correctly and fits the size of your
upper arm. if the sign points to the area marked
«» the cuff is too small and the readings will be
higher. If the sign points to the area marked « »
the cuff is too large and the readings will be lower.

6. If the arm has a conic form, the cuff should be
put on with a spiral movement as shown in the
figure
.
Fig.9
7. If the rolled-up sleeve squeezes the arm
interfering with free blood flow the Device
may give inaccurate figures not corresponding
to your actual blood pressure.

MEASUREMENT PROCEDURE
1.Connect the air hoses of the cuff and bulb to the
T-piece. Insert the T-piece into the socket on the device
casing (fig. 11).
Make 3-5 deep inhales and exhales before taking a
measurement and relax. Do not move, do not speak
and do not toughen your arm.
2.Press .
3. All symbols will appear on the display screen
for a short time, two short sound signals will be
given (fig. 12).
After the signal, the screen shows
“0” and marker “ “ starts blinking. It means that
the devise is ready for measurement (fig. 13).
4.Pump the cuff by pressing on the bulb up
to the pressure 30-40 mmHg higher than your
expected systolic (upper) pressure.
The value of the pressure in the cuff is constantly
displayed on the device’s screen. If the sum of
the expected systolic (upper) pressure plus
30-40 mmHg is less or equal to 190 mmHg, you may, for convenience, pump
the cuff until the signal (the device produces a sound when the cuff pressure
is 190 mmHg).
IF THIS SUM IS GREATER THAN 190 MMHG, CONTINUE TO PUMP THE CUFF
EVEN AFTER THE SIGNAL UP TO THE DESIRED PRESSURE, WATCHING THE
DISPLAY INDICATIONS.

ENG
DO NOT PUMP THE CUFF PRESSURE HIGHER THAN 300 MMHG SINCE IT
EXCEEDS THE DEVICE MEASUREMENT MAXIMUM. IF THE PRESSURE HIGHER
THAN 300 MMHG IS REACHED, AN INTERMITTENT SIGNAL WILL BE HEARD.
5. When the desired cuff pressure is reached, stop pressing on the bulb and put
it on the table accurately.
6. The cuff pressure then starts automatically decreasing and the marker“ “ appears on
the screen.
7. If symbol “ “, appears during pressure release, it means that the cuff has not
been pumped up to the required level. Pump the cuff up by additional 30-40
mmHg for 4 seconds above the previous value, otherwise the display will show
the error message“ ”.
8.The pressure measurement continues all the time when symbol “ “
is blinking. Try to stay motionless and not to move your arm during the
measurement.
OF THE MARKER “ “, APPEARS ONTHE SCREEN, STOP THE MEASUREMENT
AND FULLY RELEASE THE CUFF PRESSURE BY PRESSING THE PRESSURE
RELEASE VALVE. REPEAT THE MEASUREMENT FOLLOWING STRICTLY THE
RECOMMENDATIONS OF THIS MANUAL.
9.In the end of the measurement the display
will show the values of your pressure and pulse,
and the symbol
“ ” (fig. 14) will start blinking.
10. Release the remaining pressure in the cuff
using the pressure release valve.
11. For taking a new measurement repeat all
steps described in this paragraph.
TO OBTAIN THE ACCURATE RESULT MAKE INTERVAL BETWEEN
MEASUREMENTS TO RESTORETHE BLOOD CIRCULATION.WAIT FOR AT LEAST
3 MINUTES BEFORE MAKING A NEW MEASUREMENT
.
If no actions are done in mode of date and time setting for more than 3 minute,
the Device will be switched off automatically.
