Soft Keys

Each keypad key opens a set of soft key selections. Each of the soft keys has a correspond- ing soft key label area on the display. The label identifies the function of the soft key for the current Mode selection.

NOTE:

The AMPLITUDE and LIMIT keys are functionally identical.

Figures 3-3through 3-8show the soft key labels for each Mode selection.
