If the unit still appears to provide unusual or erroneous readings,
consult your physician. If the unit does not appear to be functioning
properly, contact Panasonic at 1-800-338-0552.
Specifications are subject to change without notice.
Symptom
The systolic pressure
value or diastolic
pressure value is high.
The systolic pressure
value or diastolic
pressure value is low.
The measured values
differ significantly.
The measured value
differs from that
measured by the doctor.
The measured value is
different for each
measurement.
Varying sounds and
pressurization speeds
occur during inflation of
the cuff.
The measured value
obtained is different
from that measured at
the upper arm.
Possible cause
• The hand with the cuff was held too low and
not at heart level. (See page 9)
• The cuff was not attached properly. (See
page 9.)
• You moved your hand or body or you spoke
during measurement. (See page 9.)
• The hand with the cuff was held too high and
not at heart level. (See page 9.)
• You moved your hand or body or you spoke
during measurement. (See page 9.)
• Your posture was not the same for all
measurements, or measurements were
taken without sufficient time in between.
Always wait approximately 5 minutes before
taking another reading, and above all, relax.
• Blood pressure varies in response to
minute changes in your mental state, such
as your reaction to your doctor taking the
measurement. One way to check this is to
bring the unit to your doctor’s office and
directly compare the readings taken by
your physician.
• Relax for at least 5 minutes and then take
another measurement.
• Changes in operating sounds and
pressurization speeds are normal and occur
due to the fact that measurements are
being made as the cuff is being inflated.
• For persons with certain circulation problems,
there may be substantial differences in
blood pressure values measured at the
upper arm versus at the wrist.
