Important Information Before Use
1. Blood pressure measurements should only be interpreted by a
physician or a trained health care professional who is familiar with
your medical history. Through regular use of this device and
recording of your measurements, you can keep your physician
informed of the changes in your blood pressure.
2. Perform your measurement in a quiet place. You should be seated
in a relaxed position.
3. Avoid smoking, eating, taking medication, alcohol consumption or
physical activity 30 minutes prior to taking a reading. If you are
exhibiting signs of stress, avoid taking your measurement until the
feeling subsides.
4. Rest 15 minutes prior to taking a reading.
5. Remove any constrictive clothing or jewelry that may interfere with
the cuff placement.
6. Keep the monitor stable during measurement to achieve an

6
accurate reading. Remain still; do not talk during the measurement.
7. Record your daily blood pressure and pulse readings on a chart.
8. Take your readings at the same time, each day or as recommended
by your physician to get an accurate indication of change in your
true blood pressure.
9. Wait a minimum of 15 minutes between readings to allow for the
blood vessels to return to normal. The wait time may vary
depending on your individual physiological characteristics.
10. Although such cases are rare, for those with an extremely weak
pulse or irregular pulse, errors may result which prevent proper
measurement. If abnormal variations are noticed, consult with your
physician or trained healthcare professional.
11. This device is intended for adult use. While taking a measurement,
you can stop the inflation or deflation process of the cuff at any
time by pressing the POWER button.
12. If any serious incident that has occurred in relation to the device
should be reported to the manufacturer and the competent

7
authority of the Member State in which the user is established.

Battery Installation
Inserting the batteries
•Remove the battery compartment lid on the right side of the device.
•Insert two 1.5 V AAA micro (alkaline type LR03) batteries. Make sure
that the batteries are inserted the correct way round in accordance with
the markings. Do not use rechargeable batteries.
•Close the battery compartment lid again carefully.
•All display elements are briefly displayed, flashes on the display. Now
make the settings as described below.
If the battery replacement symbol flashes, you can no longer perform
any measurements and must replace all batteries. Once the batteries
have been removed from the device, the date and time must be set
again. Any saved measured values are retained.

11
Setting the Date and Time
You must make sure that the device has the correct settings before use
in order to be able to make full use of all functions. Only by doing so
can your measurements with associated date and time be saved and
accessed later by you.
There are two different ways to access the menu from which you can
adjust the settings:
•Before initial use and after each time you replace the battery:
When inserting batteries into the device, you will be taken to the
relevant menu automatically.
•If the batteries have already been inserted:
With the device switched off press and hold the START/STOP button for
approx. 5 seconds.
In this menu you can adjust the following settings in succession:

Applying Your Cuff
General rules when measuring blood pressure yourself
•In order to generate as informative a profile of the progression of
your blood pressure as possible and ensure that the measured values
can be compared, you should measure your blood pressure regularly
and always at the same times of day. It is recommended that you
measure your blood pressure twice a day: once in the morning after
getting up and once in the evening.
•You should always carry out the measurement when you are
sufficiently physically rested. You should therefore avoid taking
measurements during stressful periods.
•Do not take a measurement within 30 minutes of eating, drinking,
smoking or exercising.
•Before the initial blood pressure measurement, make sure always to
rest for about 5 minutes.
•Furthermore, if you want to take several measurements in succession,

14
make sure always to wait for at least 1 minute between the individual
measurements.
•Repeat the measurement if you are unsure of the measured value.
Attaching the cuff
•Fundamentally, blood pressure can be measured on both arms.
Certain deviations between the measured blood pressure on the right
arm and left arm are due to physiological causes and completely
normal. You should always perform the measurement on the arm with
the highest blood pressure values. Before starting self-measurement,
consult your doctor in this regard. From this point on, always take
measurements on the same arm.
•The device may only be operated with the cuff attached when
supplied. Before using the device, the user should check the fit of the
cuff and, in doing so, ensure that their wrist circumference is within
the range printed on the cuff.
•Uncover your wrist. Ensure that the circulation of the arm is not
hindered by tight clothing or similar.

15
•Now place the cuff on the wrist so that the palm of your hand and the
device display are facing upwards.
•Position the cuff so that there is a distance of 1.0 –1.5 cm between it
and the heel of your
hand.
•Now fasten the cuff tightly around your wrist using the
hook-and-loop fastener. Make sure
that it is tight but that it does not cut into your wrist.
Adopting the correct posture
•To carry out a blood pressure measurement, make sure you are sitting
upright and comfortably. Lean back and place your arm on a surface.
Do not cross your legs. Place your feet next to each other flat on the
floor.
•Always make sure that the device is at heart level during the
measurement. Otherwise significant measurement deviations can
occur due to physiological causes. To do so, place your elbow on a

16
table to support your arm. In order to make the measurement even
more comfortable for you, you can place your lower arm on a suitable
object (e.g. the storage box).
•Relax your arm and the palm of your hand.
•To avoid distorting the measurement, you should remain as still as
possible during the measurement and not speak.
