Center-press joystick ( ): The joystick may be moved either “left or right” or “up or down.” In addition, the center of the joystick
may either be “pressed” or “pressed and held.”
•
Gain toggle ( ): The two ends of the gain toggle act as separate buttons. One end is the “Gain DOWN” button, while the other end is
the “Gain UP” button. Either end of the gain toggle can either be “pressed” or “pressed and held.”
•
Function toggle ( ): The two ends of the function toggle act as separate buttons. One end is the “Function 1” button, while the other

Note:
The gain toggle is always at the top of the instrument, and the end of the function toggle closer to the display is always the
