Depending on the current screen or operation condition, some of the buttons displayed on the
screens may not be valid. These invalid buttons are dimmed and cannot be clicked.
Most of the buttons necessary for operation are icons. When you position the mouse pointer
on one of these icon buttons, the name of the button and some sentences will appear to
describe the function of the button, or to describe why the button is invalid. If it is not
necessary to display these sentences, change the condition set in the “Control Description”
area while referring to Sec. 4.7.1 “General”. Note that these sentences appear on the
uppermost window and panel only.
Notice
For buttons the use of which is restricted by using the Authorize setting stated in 4.7 “Options
panel,” an untrue reason, for example, “… cannot be used because it is not connected at
present,” may be displayed.
