Top view isn't displayed correctly. Coordinate system

Hi everyone,

I've just starting to learn MicroStation but struggle with setting a suitable coordinate system and a top view. My default settings look like it is polar system and a top view isn't parallel to the screen (at least a grid isn't, please take a look at the print screen). I would like to set it how it is usual in AutoCAD, but don't know how to do it. Could you please help me? Thanks.
