Change Position of scroll down-arrow in Header area

I have the WeddingFocus theme installed, powered by the Photofocus theme. by default there is an arrow pointing down in the header area in the bottom right corner that makes the site scroll to the content when clicked. Since I have the Meks audio player plugin installed that adds a sticky audio player to the bottom of the site, the button can not be seen. how can I change the position of the scroll down button? thanks in advance!
