Fig. 37. Edit Call for Service message
The title displays which line of the message currently is being edited in addition to the line
number displayed on the left side of the edit line. Up to 5 lines of the message is displayed
in the page main body area. The line being edited is always positioned in the center of the
main body with the text characters underlined and is called the "edit line". When the input
focus is on the "edit line" the message text can be edited. The up and down arrow buttons
are used to scroll through the alphabet to choose the character for each text character. The
up and down arrow buttons can be pressed and held to repeatedly scroll the characters.
The right and left arrow buttons are used to change the input focus to each character
position in the line.
The navigation bar at the bottom of the edit page has commands that are selectable for the
following functions (see Fig. 38):
• "Prev line" – go up to previous message line (line above)
• "OK" – accept and save message text changes (exit this page)
• "Cancel" – do not save any message text changes (exit this page)
• "Next line" – go to next message line (line below)
Fig. 38. Call for Service edit commands
The edit commands are accessed from the edit line from either the first or last character
positions. When the input focus is on the first character position of the edit line a left arrow
button action navigates the input focus down to the navigation bar commands. When the
input focus is on the last character position in the edit line a right arrow button action also
moves down to the navigation bar.
The right and left arrow buttons are used to tab between the edit commands on the
navigation bar. Pressing the OK button causes the highlighted command to be executed.
When the "OK" or "Cancel" command is executed the edit page is exited and control returns
back to the Call for Service menu. Pressing the up or down arrow button from the command
line navigates the input focus back to the edit text line.
The message can be tested to see what it would look like when a lockout occurs by selecting
the "Test message" line (see Fig. 39). The message continuously displays until the user
presses any button to stop. After a button is pressed and released the simulation is stopped
and control returns back to the Call for Service menu.
