Not sure what the book says, but if the ground vis is crap, I'd be monitoring both tower and ground (or CTAF) while repositioning to listen for and anticipate the location of any traffic taxiing for departure or arriving on a procedure that may be planning on taxiing or parking near where you are operating. Light up your aircraft like a xmas tree and self announce your intentions. You dont want to come face to face with a large prop.
And stay the hell away from the runways as incursions end in severe bollockings at best
