6.2. Troubleshooting
Problem Solution
The display remains blank when the
device is switched on, although the
batteries are in place.
• Check batteries for correct polarity
and if necessary insert correctly.
• If the display is unclear, reinsert
batteries or replace them.
The device frequently fails to measure
the blood pressure values, or the values
measured are questionable.
• Check the positioning and t of
the cu.
• Measure the blood pressure again
in a quiet environment , following
the steps outlined in section 3.
Blood pressure measured diers
from those values measured by the
doctor. Every measurement produces
a dierent value although the device
functions normally and the values
displayed are normal.
• Attempt to measure your blood
pressure at the same time of day, as
blood pressure changes during the
course of the day.
• Record the daily values and consult
your healthcare professional.
