Radio Buttons and Check-Boxes in UNIX
Radio buttons are a group of screen buttons within which you can select only one. When you select one button, all the others are automatically deselected. The Pulse and Tone buttons in Communication Parameters... form a radio button group.
Check-boxes on a screen can be chosen individually. You can select or deselect each box regardless of the state of other check-boxes. The Actions for Selected Events boxes in Event Actions... are examples.
This standard radio button and check-box terminology is used in this User's Guide even though the UNIX version of PowerChute plus has buttons and boxes that are slightly different in appearance from those for other operating systems.
