Traveling L&D Nurse

I'm a traveling L&D nurse on 13 week contracts through agency.I'm finding out as I travel that every hospital has been challenging in regards to their charting systems. I'm on assignment now in which they chart on centricity. I've always used trace-vue. As all traveling nurses know you have no orientation and if you do its 3 days. No one seems to know where the centricity user manuel is located on this assignment. Can anyone help me in locating user manuel?
