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 LD7 ) (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
.
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). This
device has 2 memories 60 cells each used for storage of measurement results and a
clock with calendar and alarm features. An individual digital thermometer is integrated
in the device for measurement of room temperature. 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 pres-
sure 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, 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 poly-
clinic. 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 tem-
perature, 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 dia-
stolic 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 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 .

ENG
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.
POWER SUPPLY OF THE DEVICE
This device is powered from two types of sources:
1. MAIN BATTERIES: four AA batteries (1.5V) or ~220-240V supply network
(hereinafter referred to as “power supply”). The main batteries support
tonometer operation (cuff inflation, measurement and indication of results)
with such functions as current time and date displayed.
2. BACKUP BATTERY: one CR2020 (3V) battery that supplies power to an internal
clock (time/date) when main batteries fail operating (e.g. in case of replacement
of discharged batteries for new ones).
TONOMETER, CLOCK AND ALARM FUNCTIONS ARE ACTIVATED WHEN THE DEVICE
IS POWERED FROM THE MAIN BATTERIES ONLY. WHEN THE DEVICE IS POWERED
FROM A BACKUP BATTERY, CLOCK AND CALENDAR DATA ARE NOT DISPLAYED.
BEFORE THE FIRST USE REMOVE A PLASTIC GASKET THAT IS FITTED BETWEEN
CONTACTS AND BACKUP BATTERY.
For replacement of MAIN batteries:
1. Remove a support sliding it down off the electronic unit (Fig. 1). Open the battery
compartment cover and insert 4 AA batteries as outlined in the drawing inside the
compartment (Fig. 2).
2. Make sure that the battery polarities match those indicated inside the compartment.
Do not apply excess force when removing a support and battery compartment
cover. Close the battery compartment cover and fix the cuff support.

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. 8).
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.
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. 10).
6. If the arm has a conic form, the cuff should be put on
with a spiral movement as shown in the figure (fig. 11).
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. 12).
