Click open the configuration box on the camera preview screen. In there you can either choose "Infinity focus" (if available) instead of "Auto-focus". That will use a maximum focus length on your camera.
If "Infinity focus" is not available, another option is to use "Auto focus", wait for suitable focus, and then click the focus icon so that it becomes green. This will lock your focus to where it was.
