Specific features of the SC 7400 NFC
- The product uses most advanced technology for
reliability in blood pressure measurement. The blood
pressure is measured while the cuff is inflating (smart
logic).
- No need ever to worry about batteries. The product
has a built-in lithium power source.
- Data can be transferred to a smart phone/tablet by
NFC (if an NFC capable smart phone/tablet is used). For this, install the free BPM OUcare app.
- At rest, the product
displays the time and the
room temperature.
Precautions
1. Do not overinflate the cuff because the pressure
on the arm will be painful.
2. Open the velcro fastener when the inflation
pressure is higher than 300 mmHg.
3. Keep the blood pressure monitor out of reach of
children to avoid misuse.
4. The BP monitor is not a substitute to your visit to a
doctor. Diagnosing and treating a disease and
prescribing drugs are the doctor’s job.
5. The BP monitor cannot work as it normally should
when it is used outside the specified temperature
and humidity ranges (see Technical Specifications).

6. Do not eat or smoke and do not move during the
measurement. Do not drink coffee or alcohol half an
hour before a measurement.
7. Relax 5 or 10 minutes before the measurement.
8. Wait 3 to 5 minutes before making the next
measurement.
9. Always make the measurement at room
temperature. Do not use the product near a
microwave oven.
10. Remember that your blood pressure is subject to
natural variation. The pressure is highest under
stress and lowest when you sleep.
11. Ask your doctor to explain your state of health
and the blood pressure range before you start
making measurements at home.
12. If you suffer from disease, such as:
arteriosclerosis, diabetes, liver or kidney problems,
circulatory disorder or hypertension, consult your
doctor before using the blood pressure monitor.
13. During the measurement, the device displays
possible cardiac arrhythmia such as arterial or
ventricular extrasystoles or atrial fibrillation.
14. If you do not tolerate the measurement for any
reason, press the ON/OFF button to switch off the
device and deflate the cuff immediately.
15. Handicapped individuals should not themselves
measure their blood pressure.
16. Do not make changes to the device or the cuff.
Stop using the device when you believe that it is
defective.

the period between two heart beats is 5/3 the time of
the average heart beat and this abnormality occurs
three times during a measurement. Consult a doctor
when cardiac arrhythmia occurs frequently.

PLEASE NOTE:
If you do not use the product for a longer time, recharge the battery every 3 to 6 months to prevent the
deep discharge of the LiPo battery.
Product description and intended use
The blood pressure monitor is an electronic device
for the non-invasive self-measurement of the human
blood pressure and the heart rate in adult persons by
the oscillometric measuring method on the left
exposed wrist of an adult person at home at room
temperature. Handicapped persons themselves
cannot use the blood pressure monitor; they need
the assistance of a person without a handicap. The
measuring values can be transferred to a smart
phone or tablet computer by NFC. For that, install the
free BPM OUcare app.
About bood pressure
What is blood pressure?
The blood pressure is generated by the force of the
blood flow against the arterial walls after the heart
has pumped the blood in the circulatory system.
What are the systolic and the diastolic pressure?
The systolic pressure is the highest pressure while
the heart contracts; the diastolic pressure is the
pressure while the heart is at rest.
- 5 -
The WHO (World Health Organization) defined the
blood pressure levels as follows in 1999:
What is low blood pressure?
Low blood pressure causes several uncomfortable
symptoms such as dizziness or drowsiness but is
less harmful than high blood pressure.
Blood pressure variations
The blood pressure in humans varies during the day
(see chart). The causes are:
Eating, bathing, doing sport, smoking, drinking
alcohol, physical and mental stress, breathing,
conversation, exercise, changes of temperature and
humidity, etc.

Putting on the cuff and measurement position
1. Check to be sure that the circumference of your
wrist fits the cuff.
2. Place the cuff around your exposed left wrist.
Interfering clothes and jewellery should be removed
beforehand. The top edge of the monitor should be 1
or 2 cm away from the wrist.
3. Close the cuff. Do not put on
the cuff very tightly.
4. Sit upright on a chair at the
table. Put your feet flat on the
floor. Relax.
5. Make sure that the cuff is on
an imaginary line with the heart.
(See opposite figure).
6. Start the measurement with
the ON/OFF button. Do not
move or speak.
7. If you cannot make the measurement on the left
wrist, use the right wrist.
