4. SETTING UP YOUR BLOOD PRESSURE MONITOR
4.1 Inserting the batteries
After you have unpacked your device, insert the batteries. The battery
compartment is located on the back side of the device (see illustration).
a) Remove cover from the bottom plate, as illustrated.
b) Insert the batteries (4 x size AA ). Always use AA long life batteries
or alkaline 1.5v batteries. Do not use rechargeable batteries.
c) If a battery warning appears in the display, the batteries are discharged
and must be replaced.
Attention!
• After the battery warning appears, the device will not operate until the batteries have been replaced.
• If the blood pressure monitor will be left unused for long periods, remove the batteries from the device.
• The use of rechargeable batteries is not recommended.
Functional check: Hold the ON/OFF (0/I) button down to test all the display elements. When the device
is functioning correctly, all elements should appear.
4.2. Tube connection
Insert the cuff tube into the opening on the side of the
instrument, as shown in the diagram.
5. TAKING A MEASUREMENT
5.1. Before measuring
• Avoid eating and smoking as well as all forms of exertion
directly before a measurement. All these factors
influence the measurement result. Relax by sitting in an
armchair in a quiet atmosphere for about ten minutes before
a measurement.
• Remove clothing from your upper arm.
• Always measure on the same arm (normally left).
• Take measurements at the same time of day, since blood pressure changes during the course of the day.
5.2. Common sources of error
Note: Comparable blood pressure measurements always require the same conditions!
(quiet conditions).
• Supporting your arm can increase blood pressure. Make sure you are in a comfortable, relaxed position and
do not flex any of the muscles in the arm during the measurement. Use a cushion for support if necessary.
• If the cuff is considerably lower or higher than the heart, an erroneously higher or lower blood pressure will
be measured! (Each 15 cm difference in height results in a measurement error of 10 mmHg!)
• Selecting the correct cuff size is of extraordinary importance. The cuff size is dependent upon the
circumference of the arm (measured in the center). The permissible range is printed on the cuff. If your cuff
does not fit properly, contact ADC.
Note: Only use clinically approved ADC cuffs!
• A loose cuff or a protruding air-pocket causes false measurement values.
• With repeated measurements, blood accumulates in the arm, which can lead to false results. Correctly
executed blood pressure measurements should be repeated after a 5 minute pause.

The device frequently fails to measure the blood
pressure values, or the values measured are too high).
Every measurement results in different values,
although the device functions normally and normal
values are displayed.
The blood pressure values measured differ from
measured by your doctor.
☞ Further information
Even for healthy people, blood pressure is subject to fluctuations. Comparable measurements always
require the same conditions (Quiet conditions)!
If fluctuations are larger than 15 mmHg, and/or you hear irregular pulse tones on several occasions, con-
sult your doctor.
For licensing, this device has been subjected to strict clinical tests by experienced doctors in Germany.
The manufacture of this device takes place according to the terms of the European standard for blood
pressure measuring devices (see technical data) under the supervision of the Technical Monitoring Asso-
ciation Essen (RWTüV-Essen).

if there are technical problems with your blood pressure monitor. Never attempt to repair
the instrument yourself!
Any unauthorized opening of the instrument invalidates all warranty claims!
• Fit the cuff correctly on the arm.
• Before starting a measurement, low (too
make sure that the cuff is not fitted too
tightly. Ensure clothing is not exerting
pressure on the arm above the measuring
position. Take off articles of clothing
if necessary.
• Measure blood pressure again in complete
peace and quiet.
• Blood pressure changes continually.
Your readings may be accurate.
Consult your doctor.
• Record the daily development of the those
values and consult your doctor
about them.
• Anxiety during a doctor visit can
result in higher readings.
