Blood pressure measurements determined by the UA-704 are equivalent to those
obtained by a trained observer using the cuff/stethoscope auscultation method
within the limits prescribed by the ANSI/AAMI SP-10 standard for electronic or
automated sphygmomanometers.
Corrective action
Replace with a new battery.
Place the battery with
negative and positive
terminals matching those
indicated in the battery
compartment.
Fasten the cuff correctly.
Make sure you remain very
still and quiet during the
measurement.
Adjust the cuff position.
Raise your hand so that the
cuff is at the same level as
your heart.
See Pg. E-5 “Selecting the
Correct Cuff.”
See Pg. E-12 “Keys to
Successful Monitoring.”
Remove the battery.
Place back in correctly, and
try the measurement again.
Check air tube connection
inside battery cover.
