In reviewing the Operator's Manual provided with the Workstation, we identified another problem that I don't see mentioned in this post. Page 13 states "Note: The incubator must not be used if the timer or temperature is out of specification." See also page 18 "NOTE: The incubator must not be used if the timer is out of specification". At AABB last month, I asked an Ortho rep why the incubator must be taken out of service when the timer (that does not control the temperature) is not in calibration. The Ortho rep had no idea that the operator's manuals said this, claimed that it must be an error and recommended not following the operators manual. I also asked how to validate that the green light actually turns off when the incubator gets too hot. They had no suggestions. We discussed taking daily temperatures without wasting a large number of gel cards. They had many suggestions that did not follow the very specific instruction's in their operator's manual on how to achive this goal.
