No measurements on non-work days
In «DIAG.» mode, blood pressure measurements are
taken on 7 consecutive working days (or normal
week days). Do not take measuremetns on
«non-working» days (or particularly relaxing days)
in this mode!
Two sets of measurements per day
ESH guidelines recommend one double measurement
to be taken in the morning between 06:00 - 09:00 and
one in the evening between 18:00 - 21:00. Always take
the measurements before taking your medication,
unless otherwise directed by your doctor.

Eight steps for taking proper blood pressure
Step 1
Avoid taking measurements directly after eating,
drinking or smoking. Allow at least one hour between
these activities and measurement of your blood pressure.
Step 2
Prepare a chair and table for the measurement. The
chair should have a vertical back-rest and the table
should allow your upper arm to rest at the same height
as your heart.
1 Hour Before

EN
16
Step 3
Remove all clothing covering or constricting the arm to
be measured. Apply the cuff. Make sure the lower edge
of the cuff is exactly 2–3 cm from the inner fold of your
arm. The tube connecting the cuff to the device should
be placed on the inside of the arm. (Additional visual
instruction can be found on the cuff)
Step 4
Sit down and relax for at least ve minutes prior to the
measurement.

17
Step 5
Sit upright and lean comfortably against the chair’s
backrest. Press the start button, and the device will
start to measure. During the measurement do not
move, cross your legs, or tense your arm muscles.
Breath normally and do not talk.
Step 6
When the measurement is complete, the readings
are stored for future reference by your doctor. If an
error displays after the readings, please repeat the
measurement procedure from step 1 to 5.

Step 7 (in «DIAG.» mode)
In «DIAG.» mode, there is a 60 second countdown before
the measurement starts. Two measurements will be
performed subsequently. After the rst measurement
another 60 second countdown starts before the second
measurement. Be relaxed and do not move during the
countdown.
Step 8 (in «DIAG.» mode)
When seven days of measurements have been collected,
the Doctor Symbol will ash on the display. Do not forget
to take your WatchBP Home N device with you on your
next visit to the doctor. (Note: the doctor symbol is only
displayed for measurements in «DIAG.» Mode.)

Special Function
The atrial brillation indicator for early
detection
The WatchBP Home N is designed to detect atrial brillation
during blood pressure measurements in the «USUAL» Mode,
«DIAG.» Mode and «NOCTURNAL» Mode. When atrial
brillation is detected, the Ab icon is displayed. The device
can detect atrial brillation with high accuracy (sensitivity
of 95% and specicity of 86%)*. If the atrial brillation
icon is displayed after the measurement, it is recommended
to visit a doctor.

* Atrial brillation is a major cause of stroke which can be
detected by this device. However, not all risk factors for
stroke, including atrial utter, may be detected by this
device.
* This device may not detect atrial brillation in people with
pacemakers or debrillators. People with pacemakers or
debrillators should therefore not use this device to detect
atrial brillation.
