Information windows are displayed while you are entering data or using
control functions. They give you extra details pertaining to what is about
to happen, or let you acknowledge a command. Information windows
always appear with the word "INFO " in a small box.
Question windows appear when the 941X needs to know more about
what you want to do. A question mark will always appear in this type of
window.
You must respond to any question window by pressing ENTER to answer
"YES," or CLEAR to answer "NO." All other keys, including the function
keys, are inactive when a question window is displayed.
