In OB exams, an accurate date and time are critical for accurate obstetrics
calculations. Verify that the date and time are accurate before each use of the
system. The system does not automatically adjust for daylight savings time
changes.
Verify the patient information, date, and time settings are accurate.
Before starting a new calculation, start a new patient exam to delete the previous
measurements. See “New Patient” on page 41.
Prior to use, verify OB custom table data entries are correct. The system does not
confirm the accuracy of the custom table data entered by the user.
