Section 2: Pump Setup and Programming
WARNING: If a gap is present anywhere between the battery
door and the pump housing, the door is not properly latched. If
the battery door becomes detached or loose, the batteries will
not be properly secured; this could result in loss of power,
nondelivery of drug, and, depending on the type of drug being
administered, death or serious injury to the patient.
