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 LD3 (LD3a) (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 and pulse rate
measurement. Wrap the cuff around your upper arm and it starts to be inflated
automatically. 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
(t he 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 2 memories,
by 30 cells, for storage of measurement results. 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

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
(approximately 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 peo-
ple may be 30-50 mmHg of systolic pressure and to 10 mmHg of diastolic pres-
sure. 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
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 tem-
perature. 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 min.). 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
BATTERY INSTALLATION
1. 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 (fig. 1).
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.

of EPS from mains socket and disconnect plug connector from the Device.
SETTING OF DATE AND TIME
To shift to mode of date and time setting, it is necessary, holding M1, depress .
Selected parameter will blink. Change of selected parameter toward increasing
is taking place when depressing M2, towards decreasing – when depressing M1.
To shift to setting of the next parameter, year/month/hours/min, it is necessary
to depress .
If no actions are done in mode of date and time setting for more than 1
minute, the Device is independently changed over to mode of date and time
indication.
When power cells are replaced, date and time will zero.
Measurement of pressure and pulse is possible without date and time
setting. Indication of date and time is not switched off. Current consumption
in this case is negligible.
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 (fig. 3).
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 (fig. 4).

CUFF PREPARATION
1. Insert the cuff end for about 5 cm into a
metal ring as shown in the figure 5.
Fig. 5
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
. 6). Fig. 6
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. 7).
Fig. 7
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. 8).
Fig. 8
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 (fig. 9).

6. If the arm has a conic form, the cuff should be
put on with a spiral movement as shown in the
figure (fig. 10).
Fig. 10
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
( fig. 11 ) .
Fig. 11
MEASUREMENT PROCEDURE
1.Insert the Air Tube Plug into the Cuff Jack. 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
and the Device will inflate automatically the air
into the cuff (fig. 12),
4. After level 18-20 mm Hg is reached, cuff will start
to be pumped in, first slowly, then quickly. During
pumping in sign « » is blinking. Algorithm IMS
makes it possible to determine systolic and diastolic
pressure in the process of pumping in
(fig. 13) .
5. At the end of measurement, depending on
classification of result according to scale of World
Health Organization (WHO), short sound signals
will ring out: 1 signal – normal pressure; 2 signals
– increased pressure within the norm; 3 signals –
hypertension. After that the device will release all
air from cuff and measured arterial blood pressure,
pulse rate and time of measurement will be
displayed on the display (fig. 14). Symbol « », is
blinking on display, reminding that to retain results,
it is necessary to choose memory 1 or 2, having depressed M1 or M2, respectively.
If not to choose memory within 3 minutes, the result will not be memorized, and
the device is automatically switched over to mode of date and time indication.

If irregular pulse rhythm is detected during measurement, symbol of arrhythmia
«», will appear and blink upon measurement end.Appearance of arrhythmia
indicator may also be caused by movement of body 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. 14). Scale WHO – three-color scale of classification of received value of
arterial pressure, according to recommendation of World Health Organization
(fig. 15). The scale is located in the left corner of display.
6. Press to shift to mode of date and time setting .
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.
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.
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 arm cuff quickly
completely deflates and
the Device is independently changed over to mode of
date and time indication
.
MEMORY FUNCTION
1. Result of each measurement (pressure, pulse, time and date of measurement)
may be kept in the Device memory. For this purpose, after measurement, within
not more than 3 minutes, memory M1 or M2 shall be selected for memory
storage.
IF THE NOTICE ON ERROR APPEARS THE
MEASUREMENT RESULT WILL NOT BE STORED .
