3.6.1 Keypad description
The keypad includes the numeric keypad, soft keys, and function keys.
Numeric keypad
The numeric keypad consists digits 0 through 9, a +/- key, and a decimal key.
Soft keys
Soft keys are blank, white keys located to the left and right of the display.
The appearance of each function key depends on the display. The key is not active when
there is no function displayed. The soft keys appear on the display and point to the proper
soft key to push for that action.
In some cases during a programming step an item from a list needs to be selected. The
soft keys on the right side of the display will change to display “up” and “down” arrows.
Scroll up and down the list of choices.
