Recommended Action
Replace all batteries with new ones.
Reinstall the batteries with negative
and positive terminals matching those
indicated on the battery compartment.
Replace all batteries with new ones.
Apply the cuff correctly.
Make sure you remain very still and
quiet during measurement.
Sit comfortably and still. Place your
arm on a table with your palm facing
upward and the cuff at the same level
as your heart.
If you have a very weak or irregular
heartbeat, the monitor may have
difficulty in determining your blood
pressure.
At a clinic or doctor's office
apprehension may cause an elevated
reading. Home measurement reduces
the effects of outside influences
on blood pressure readings,
supplementing the doctor's readings.
Remove the batteries. Place them
back properly and try the measurement
again.
