The menu field changes depending on the mode of the Analyzer and the buttons that have been pressed. It indicates the current function of each of the 8 push buttons below the display. See Section 2.2.2 for information on using the push buttons.

2.2.2 Programmable push buttons

The 8 push buttons below the display are programmable by the CPU in that their functions change depending on the mode of the Analyzer or the operations being performed. The legend above a button identifies its current function. If there is no legend above a button, it has no function and will be ignored if pressed.
