Press the Interface List button on the top of your Lemur.

The upper left corner of the screen of the Lemur should look something like this.

•

Touch the picture of the interface you want to use, and it instantly covers the entire
screen.

•

Next, try pressing the Navigation buttons on the top of the Lemur.

      

They move from one interface screen to the next with a single button press.
