WARNINGS

To avoid incorrect calculations, verify that the patient information, date, and
time settings are accurate.

To avoid misdiagnosis or harming the patient outcome, start a new patient
form before starting a new patient exam and performing calculations. Starting
a new patient form clears the previous patient’s data. The previous patient’s
data will be combined with the current patient if the form is not first cleared.
See “Entering patient information” on page 4-31.
