Troubleshooting
Problem
My blood
pressure
fluctuates
throughout
the day.
My blood
pressure
measure
ment from
the hospital
is different
from the
measure
ment at
home.
The result is
different
when I
perform
measure
ments on
my right
wrist.
The blood
pressure
monitor
does not
work when I
press the
'on' button
The light of
the display
dims and a
battery

is showing
The display

Possible
cause
Your
measurement
position, the
conditions
under which
you measure
or the time of
measureme
nt, are
different
during each
measureme
nt.
Fluctuations
of blood
pressure
during the
day are
normal.
You are using
medication.
You
performed
multiple
measure
ments
directly after
each other.
Multiple
variables may
affect your
blood
pressure such
as the
weather,
emotions
and exercise.
The blood
pressure
monitor is
suitable to be
used on both
wrists, but the
measurement
results on the
right wrist
and left wrist
will differ.
The
rechargeable
battery is
empty.
The lock
switch is set
to the
'locked'
postion.
The battery is
low.
Communica
tion error.
The cuff is
not properly
secured.
The device
detected
motion,
talking or the
heart rate is
too weak
during the
measureme
nt.
The device
does not
detect the
heart rate.
The
measurement
failed.
Solution
For a meaningful
comparison, try to
measure under
similar conditions.
For example, take
daily
measurements at
approximately the
same time, on the
same wrist, or as
directed by a
doctor.
Blood pressure
fluctuates from
minute to minute
and normally
shows a circadian
rhythm over a
24-hour period,
with highest
readings in the
afternoons and
lowest readings at
night. That is why,
for comparable
measurements, the
measurements
should be taken at
approx. the same
time of day.
The variations in
blood pressure can
be greater if you
are using
medication.
Wait at least 3
minutes between
measurements.
This allows your
blood circulation to
recover.
Pay attention when
you measure your
blood pressure at
home. Check for
instance:
If the cuff is not too
tight or too loose.
If the cuff is
properly attached
on the wrist.
If you feel anxious
or stressed, try to
relax. Take a deep
breath 2-3 times
before you start a
measurement.
Advice: Rest for 5
minutes before you
measure your
blood pressure.
For a meaningful
comparison, try to
measure under
similar conditions
and measure on
the same wrist
every time.
Recharge the
battery (see
'Charging').
Set the lock switch
to the 'unlocked'
position (Fig. 7).
Charge the battery
(see 'Charging').
Check if the app is
on and try data
transmission again.
Refasten the cuff,
wait for 3 minutes
and then measure
again.
Wait for 3
minutes and then
measure again. Do
not move during
measurement.
Make sure the
device is in contact
with the skin.
Loosen the
clothing on the arm
and measure again.
Wait for 3 minutes
and then measure
again.
