Breadboard connections for the Servo Control Panel. The S button serves to change the sign of the angle shown on the LCD screen. The A button commutes between manual control and auto-sweep. The Z button set the actual servo angle as zero. The servo knob controls the servo angle in manual mode and rotation rate in auto-sweep mode.

May i know wat is the purpose for the button to change the sign?

It serves to display the desired rotation sign. For instance, by convention a positive rotation is the wing pitch up, but maybe you munted the servo in a way that the pitch up rotation is displayed with a negative sign. With that button you can reverse the sign on display without changing the servo installation.
