Recommended Action
Replace with a new battery.
Reinstall the battery with their
negative and positive end
matching those indicated in the
battery compartment.
Fasten the cuff correctly.
Make sure you remain very still
and quiet during the
measurement.
Sit comfortably and still.
Ensure that the cuff is at the
same level as the heart.
If you have a very weak or
irregular heart beat, the device
may have difficulty in determining
your blood pressure.
See "Why measure blood
pressure at home?".
Remove the battery. Place it back
properly and try the
measurement again.
