Possible Malfunctions and their Remedy
Malfunction
Remedy
The display remains
empty when the
instrument is switched
on although the
batteries are in place.
1. Check batteries polarity is correctly located and
if necessary insert correctly.
2. If the screen display is unusual, the batteries
should be re-inserted or replaced.
The device frequently
fails to measure blood
pressure, or the values
measured are too low
or too high.
1. Check the positioning of the cuff.
2. Measure the blood pressure again in a quiet
environment.
Blood pressure
measured differs from
those values measured
by the doctor.
Record daily measurements and consult your
doctor.
Individuals visiting their doctor frequently
experience anxiety which can result in a higher
reading at the surgery than obtained at home
under resting conditions.

Care, Maintenance, Recalibration and Disposal
Care
This instrument contains sensitive components and must be treated carefully.
• Protect the monitor from water and moisture, temperature extremes, impact
and dropping, dust or direct sunlight.
• The cuff contains a sensitive air-tight bladder. Handle this carefully to avoid
any damage caused through twisting or buckling.
• Ensure that infants do not use the monitor unsupervised as some
parts are small enough to be swallowed.
Maintenance
Clean the blood pressure monitor with a soft, dry cloth. Stains on the cuff can
be carefully removed with a moist cloth and mild soap. During cleaning, avoid
squeezing or twisting the cuff.
Do not expose any part of the monitor to chemical cleaners such as paint thinners,
turpentine, methylated spirits, etc.
