WARNING:

•C

onsult your physician or pharmacist before

starting to measure your blood pressure.

•Read and understand all instructions and

warnings before using this device.

•Like any oscillometric blood pressure mea-

surement devices, certain medical conditions
can affect the measurement accuracy, among
others:

– disorder of the cardiac rhythm
– very low blood pressure
– patients in shock
– patients with very low blood perfusion
– diabetes
– vessel anomalities
– people with electrical implants, such as a

cardiac pacemaker

– women who are pregnant.

•D

ue to their condition the oscillometric mea­surement method can produce incorrect read­ings. This represents a risk for your health,

since values may be interpreted incorrectly.
Always consult your physician to determine
what will be suitable for you.

•T

his product does not and is not intended to
provide a medical diagnosis. Measurements
results are for reference only. Self-diagnosis
and treatment, e.g. regarding medication,
using measured results represent a risk for
your health. Always consult with a licensed
physician for determination of appropriate
medication and dosage thereof. Follow the
instructions of your physician or licensed
healthcare provider. If you have or suspect
that you have a medical problem, promptly
consult your physician. If you have an emer­gency please call 911 immediately.

about your blood pressure.

•P

lease note that technically related measur­ing tolerances are possible. Please see sec­tion ‘13. Technical Specifications’ for details.
NOTE: A single measurement does not pro­vide an accurate indication of your true blood
pressure. You need to take and record several
readings over a period of time. Try to measure
your blood pressure at the same time each
day for consistency.

•Any cuff related blood pressure measurement

in high repetition rates, can lead to severe
measurement side effects, e.g.
– any nerv compression with temporary arm/

hand paralysis

-

– the release of an arterial or venous throm-

bus, which can cause a life threatening
situation.

•Please contact your physician about the

specific risks of cuff pressure in your spe­cific case.

•The ’irregular heartbeat’ function does not

replace a cardiac examination, but may help
to detect potential pulse irregularities at an
early stage. Always consult your physician to
determine what will be suitable for you.

•The ’irregular heartbeat’ function is not

designed for diagnosing or treating an
arrhythmic disorder. Arrhythmia can only be
ascertained by a licensed physician.

in injury.

•Remove any kind of wrist jewelry or the like

before taking a measurement. This could
cause bruises.

•Do not place the cuff over heavy clothing (e.g.

a jacket or sweater sleeve) as the blood pres­sure monitor will not be able to take a proper
measurement and there is an elevated danger
of acquiring hematoma or skin marks during
the course of the measurement.

•I

n case the cuff does not stop inflating, inter­rupt the measurement by pressing the start/
stop button and open the cuff at once.

•D

o not disassemble the unit, it may result in

injuries.

•When applying the cuff, make sure there

are no wrinkles in the cuff. This could cause
bruises.

•Blood pressure measurements can lead to

temporary marks on the skin at the site of
the cuff placement. This is especially the
case in high repetition rates, in hypertonic
patients and in patients with weak pulses. In
rare cases a mark may persist for a couple
of days. Please contact your physician about
these specific risks of cuff pressure in your
specific case.

•For hygienic reasons the cuff is intended only

for the use by one person.

•It is inappropriate for people with serious

arrhythmia to use this Electronic Sphygmo
manometer.

•Prolonged over-inflation (cuff pressure

exceeds 300 mmHg or maintained above

9

-

15mmHg for longer than 3 minutes) of the
bladder may cause ecchymoma of your arm.

•Please note that when inflating, the functions

of the limb in question may be impaired.

•Do not place the cuff over wounds as this may

cause further injury.

•The accuracy of any blood pressure measure-

ment with this device can be affected by a
multitude of causes. Some can be avoided

Cleaning and storing the device and cuff

To keep your digital blood pressure monitor in the
best condition and protect the unit from damage
follow the directions listed below:

•D

o not use any cleaning agents or solvents.

•Under no circumstances hold the device and

cuff under water, as this can cause liquid to
enter and damage the device and cuff.

•If you store the device and cuff, do not place

heavy objects on the device and cuff. Remove
the batteries.

•Clean your device and cuff carefully only with a

slightly moistened soft cloth and dry it immedi­ately with a soft dry cloth.

•When storing the device, make sure that no

heavy objects are placed on top of it.

•D

o not fold the cuff tightly. If the unit is stored
near freezing, allow it to acclimate to room tem­perature before use.

•Always store the unit in its storage case after

use.

•T

his unit may not meet its performance spec­ifications if stored or used outside of the tem­perature and humidity ranges (see section ‘13.
Technical Specifications’).

•Use the unit consistent with the instruction pro-

vided in this manual.

Advice on use

•For consistency, always measure your blood

pressure at the same time each day.

•A

lways wait at least 5 minutes between mea­surements to allow the blood circulation in
your arm to return to normal. You may need to
increase the wait time depending on your indi­vidual physiological characteristics. Because
of normal physiologic changes and the many
external factors influencing blood pressure, it
is unusual to obtain identical blood pressure
measurements, even when taken a few minutes
apart. Speak with your physician to determine
what is affecting your blood pressure and which
variation may be seen as normal in your case.

12

•When performing multiple measurements on

an individual, wait five minutes between each
measurement.

•D

o not take a measurement within 30 minutes
of eating, drinking, smoking or exercising. You
should not be physically tired or exhausted
while taking measurement.

•R

epeat the measurement if you are unsure of
the results.

•Measurements are for your information only

– they are no substitute for a medical exam­ination. Discuss the measurements with your
doctor and never base any medical decisions
on them (e.g. medicines and their administra­tion).

•Do not use the blood pressure monitor on new-

borns, pregnant women or patients with pre-ec­lampsia. Consult your doctor before using the
blood pressure monitor during pregnancy.

•C

ardiovascular diseases may lead to incorrect
measurements or have a detrimental effect on
measurement accuracy. The same also applies

to very low blood pressure, diabetes, circula­tory disorders and arrhythmias as well as chills
or shaking.

•F

or reliable monitoring and reference of blood
pressure, keeping long-term records is recom­mended.

•To minimize measurement variations due to

physical activity, rest at least 5 minutes before
measuring your blood pressure (or 15 minutes
after strenuous activity).

•S

tress raises blood pressure.

•P

erform measurements in a quiet and relaxed
environment at room temperature.

8. Evaluating Results

Irregular Heartbeat:

This device can detect irregular heartbeat pat­terns during measurement and will indicate them
by displaying the irregular heartbeat indicator

.

This may be an indicator for arrhythmia, which is
a condition where the heart rhythm is abnormal.
These symptoms (omitted or premature heart­beats, slow or excessively fast heart rate) may
be caused, among other things, by heart disease,
age, physical predisposition, excessive use of
stimulants, stress, or lack of sleep. Arrhythmia
can only be ascertained through examination by
your doctor.

Repeat the measurement if the Irregular Heartbeat
Indicator displays after a measurement. Rest for
at least five minutes between measurements and

22

do not talk or move during measurement. If the
icon appears often, contact your doctor, since
self-diagnosis and treatment based solely on the
test results may be dangerous. It is vital to follow
your doctor‘s instructions.

9. Classification Categories

Measurements can be classified and assessed by
the table below. However, these standard values
are only a general guideline, since individual blood
pressure varies in different people and different
age groups, etc.

It is important to consult your doctor regularly for
advice. Your doctor will tell you your individual
values for normal blood pressure as well as the
value above which your blood pressure is classi­fied as dangerous.
The classification on the display and the scale on
the unit show which category the recorded blood
pressure values fall into. If the systolic and dia-

stolic values fall into two different categories, the
classification Indicator on the unit always shows
the higher category.

10. Displaying and deleting
measurements

The results of every successful measurement
are stored together with the date and time. The
oldest measurement is overwritten in the event
of more than 60 measurements.
