WARNING:
Make sure that you have selected
the OB exam type and the OB
author for the OB calculation table
you intend to use. See “Results from
System-Defined OB Measurements
and Table Authors” on page 62.
To avoid incorrect obstetrics
calculations, verify with a local
clock and calendar that the system’s
date and time settings are correct
before each use of the system. The
system does not automatically
adjust for daylight savings time
changes.
