I just bought an oregon 450t and would like to manually input the coordinates on the hand held. How do I do this??

The Oregon wiki has a lot of information on how to use your Oregon 450, look under the Knowledge Base in the left column.
To answer you question, here is how, take a look at "W3". http://garminoregon.wikispaces.com/Waypoints+and+POIs
