a. Menu Lines & Softkey Functionality
Menu lines can be selected with the ↑ key
or the ↓ key. The selected line is dis-
played as white lettering on a black back-
ground (reverse text). Menus can contain
four different types of lines:
Menu Line – A line ending with three dots
(…) indicates that it leads to a submenu.
The submenu can be activated by press-
ing the ↵ key or the → key when the line
is highlighted.
Function Line – A line ending with an
exclamation point (!) indicates that it will
start a function. The function can be acti-
vated by pressing the ↵ key or the → key
when the line is highlighted.
Variable Line – A line ending with a colon
(:) indicates that it displays a module
variable parameter. Some parameters
can be changed and some parameters
display only a status and cannot be
changed. Paramters that cannot be
changed will be displayed below a line
within the menu.
Text Line – A line without punctuation
marks displays information.
Tag Line – At the top of each menu
screen is the tag line of the current chan-
nel. To the right of the Tag is the value of
