GENERAL INFORMATION
INDICATIONS FOR USE
This Instruction Manual is designed to assist the user with safe and eective operation
of the digital blood pressure monitor DSK-1031 (hereinafter – the “Device”). The device
is designed to measure systolic and diastolic blood pressure and heart rate reading in
patients aged 12 years and older. This device should not be used for newborn children.
The incorrect measurement result is also possible when the device is operated in a baby
hand. Consult your doctor for blood pressure measurement in children. The device is rec-
ommended for use in patients with unstable (nonpermanent) blood pressure or hyper-
tension at home as a supplement to medical surveillance. The cu is suitable for a upper
arm with a circumference of about 22 - 42 cm. Blood pressure is measured in the range
from 40 to 250 mm Hg and heart rate, in the range from 40 to 160 heartbeats per minute.
OPERATION PRINCIPLES
The device uses the oscillometric method of measurement. The cu connected to
the electronic module is wrapped around the upper arm.
When you press the START/STOP button, the device starts the automatic ination,
which is followed by the blood pressure measurement. The sensor element of the
device detects slight pressure oscillations in the cu produced by the expansion
and contraction of the brachial artery in response to each heartbeat. Ination is
stopped when the cu is pumped enough to determine diastolic and systolic pres-
sure, whereupon the air is discharged from the cu. Rhythm and amplitude of the
pressure waves are measured and displayed on the LC display as a numerical value
in millimeters of mercury. The device has an arrhythmia indicator, as well as two
memories with 60 cells in each calculating the average value.
NISSEI New Technologies
Fuzzy Ination Algorithm – is an algorithm for automatic selection
of the cu ination pressure. Using this algorithm, the device by itself
determines the pressure level to which it is necessary to inate the cu
based on the patient’s systolic pressure. Owing to the Fuzzy Ination
algorithm the device becomes easier to use, while the measurement gets
more comfortable and more accurate.
Arrhythmia indicator is a special icon on the display that informs on the
irregular heartbeat, while the measurement result is correct.

an increase in pressure values. Therefore, blood pressure measured at home is often
dierent from that measured in the clinic. Since blood pressure increases at low tem-
peratures, measurements should be made at room temperature (about 20°C). If the
device was stored at low temperature, prior to using it should be kept for at least 1
hour at room temperature, otherwise the measurement result can be erroneous. Dur-
ing the day, the dierence in the readings in healthy people may attain 30-50 mm Hg
for systolic (upper) pressure and up to 10 mm Hg for diastolic (lower) pressure. De-
pendence of blood pressure on various factors is individual for each person. There-
fore it is recommended to keep a special recording of blood pressure readings. ONLY
A DOCTOR MAY ANALYZE TRENDS IN CHANGING YOUR BLOOD PRESSURE BASED ON
CORRESPONDING RECORDINGS.
4. In case of cardiovascular diseases and a number of other diseases that require
the blood pressure monitoring, measurements should be carried out in the hours
specied by a doctor. REMEMBER THAT THE DIAGNOSTICS AND ANY TREATMENT OF
ARTERIAL HYPERTENSION SHOULD BE CARRIED OUT ONLY BY A DOCTOR BASED ON
BLOOD PRESSURE READINGS OBTAINED BY A DOCTOR. MEDICAL DRUG ADMINIS-
TRATION OR CHANGE OF DOSAGES SHOULD BE MADE ONLY BY PRESCRIPTION OF
AN ATTENDING DOCTOR.

RECOMMENDATIONS ON CORRECT MEASUREMENTS
1. If treated with hemodialysis or anticoagulants, antiplatelets or steroids, refer to
your doctor about the blood pressure measurement.
2. Malfunctions are possible when the device is used near working mobile phones,
microwave ovens and other equipment generating electromagnetic radiation.
3. For correct measurement it is necessary to know that the BLOOD PRESSURE IS
SUBJECT TO SHARP FLUCTUATIONS EVEN IN SHORT TIME INTERVALS. The blood pres-
sure level depends on many factors. It is commonly lower in summer and higher in
winter. Blood pressure varies along with atmospheric pressure and depends on the
physical exertion, emotional excitability, stress and diet. Medical drugs, alcohol and
smoking exert great inuence as well. Occasionally, measurements in the clinic cause

4
ENG
urement should be carried out in a quiet comfortable atmosphere at room tem-
perature. Exclude meal an hour before the measurement, and exclude smoking, soft
drinks, and alcohol 1.5-2 hours before the measurement.
7. Accuracy of the blood pressure measurement depends on matching the device
cu and size of your hand. THE CUFF SHOULD NOT BE TOO SMALL OR TOO BIG.
8. Repeated measurements are carried out at 5-minute intervals to recover the
blood circulation. However, persons suering from severe atherosclerosis, due to a
signicant loss of elasticity of blood vessels, need longer intervals between meas-
urements (10-15 minutes).
This also concerns patients suering from long-term diabetes. For more accurate deter-
mination of blood pressure it is recommended to carry out a series of three consecutive
measurements and to calculate the average value of measurement results .

its surface. Make sure that the
place where the cu is put on
the upper arm is about the
same level as the heart and
the hand freely lies on the ta-
ble and does not move (Fig. 4).
You can also measure your
blood pressure when lying on your back. Look up, stay calm and do not move during
the measurement. Make sure that the place where the cu is put on the upper arm is
about the same level as the heart (Fig. 6).
Measured values may vary slightly, depending on the position during the
measurement. If the cu is above/below the level of the heart, resulting reading
may be incorrect (lower/higher)
CUFF PREPARATION
Fig.7
1. Apply the cu to your left upper arm so that the air
tube is directed to your palm (Fig. 7) . If the measurement
on your left arm is dicult, you may use your right arm. In
this case remember that the readings may dier by 5-10
mmHg and even more.
Fig.8
2. Wrap the cu around your upper arm so that the bottom
of the cu is approximately 2-3 cm above your elbow. Air
tube should be directed towards the palm (Fig. 8).
Fig.9
3. Fix the cu so that it ts tightly to the arm, but see that
it is not overtight (Fig. 9). Too tight or too free placement
of the cu may give inaccurate readings.

MEASUREMENT PROCEDURE
IMPORTANT! The device has touch-sensitive buttons that
are pressed by slight touching. Moisture, dirt and extraneous
objects between the nger and the device panel can aect
the ability of buttons to respond to touching.
1. Insert the Air Tube Plug into the Cu Jack.
Before measurement, take a few breaths and relax. During the
measurement, do not talk and do not move.
2. Press the START/STOP button. The deating symbol « » will
ash on the display, and the device will release the remaining air
from the cu (Fig. 12).
3. Beep will be heard, and air will be pumped into the cu.
The symbol « » will ash, and the displayed value will
increase (Fig. 13). Ination will stop at optimum level owing
to the Fuzzy Ination algorithm.
4. The symbol « » will disappear, and the measurement will
start. The cu pressure will decrease slowly.
Noise Interference Detection
This device detects the presence of extraneous sounds or noises that can af-
fect the measurement results. When such interference is detected, the symbol « ».
appears on the display. In this case, it is recommended to repeat the measurement to
eliminate the interference.
Control of Correct Fixing the Cu
The symbol « » indicates that the cu is applied
correctly, the symbol « » indicates that the cu is fastened
too tight or too loose. In this case, it is recommended to repeat
the measurement after proper xing the cu.
Press the START/STOP button to stop forcedly the measure-
ment: the device will stop ination and quickly release the air.
Automatic Additional Ination.
If on starting the measurement, the operating pressure appears to be insucient due to
hand movements or due to excessive tension in a hand, the cu will be lled with air again
to the level of about 30 mm Hg higher than the original level. Automatic additional ination
will be repeated until the measurement is completed successfully. This is not a malfunction.
5. The symbol «» will start ashing synchro-
nously with a sound signal, as soon as the
sensor catches the pulse pressure (Fig. 14).
6. When the measurement is completed, the
display will show the values of blood pressure,
pulse pressure, WHO scale and heart rate (Fig.
15). The device will automatically release the
air from the cu.
7. Press the button or button and the result
will remain in the selected memory unit .
8. Press the START/STOP button to turn o
the device.
If you forget to turn o 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 cu and proper posture during the measurement. These aspects
may inuence the measurement result. The device displays the symbol « », when
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 hand and can aect the measurement result. Give your
hand a break for at least 5 minutes.

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
related to poor elasticity of arteries and is
one of the risk factors for circulatory diseas-
es. 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 di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.
Saved values are kept with the measurement date and time, if set. If you want to
save time and date together with the measurement values, date and time should be
set before the measurement.
When an error occurs (ERR), the measurement results are not saved.

TECHNICAL DESCRIPTION
Table 204. Guidance and manufacturer’s declaration - electromagnetic immunity
DSK-1031 is intended for use in the electromagnetic environment specied below. The customer or the user of DSK-1031 should assure that it is used in such an envi-
ronment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be used no closer to any part of DSK-1031,
including cables, than the recommended separation distance calculated from the equation applicable to
the frequency of the transmitter. Recommended separation distance

Where P is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recommended separation distance in metres (m).
Field strengths from xed RF transmitters, as determined by an electromagnetic site survey,1should be
less than the compliance level in each frequency range.2
Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption and reection from structures, objects
and people.
1Field strength from xed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radios broad-
cast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to xed RF transmitters, an electromagnetic
site survey should be considered. If the measured eld strength in the location in which DSK-1031 is used exceeds the applicable RF compliance level above, DSK-
1031 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
DSK-1031.

Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.

Table 206. Recommended separation distances between portable and mobile RF communications equipment and DSK-1031
DSK-1031 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of DSK-1031 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and DSK-1031 as recom-
mended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be estimated using the equation ap-
plicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption and reection from
structures, objects and people.
