> Q. What do these icons mean, and why do some of them change or disappear?
> A: The icons shown below comprise the status functions and system functions of the S331L Site Master. Each one when touched, functions like shortcuts to specific status information, setup screens, or direct access to functions like Screenshot and Save. The Lock icon appears only when the touch screen has been manually locked by the user. The Globe icon changes to indicate different GPS status. The system function icons to the right of the Lock icon disappear in Classic Mode.
