The up and down arrow buttons are used to scroll through the menu lines. A “Next page” symbol is displayed on the menu
line if it is selectable for an action (all menu lines except for the message itself). When a selectable menu line has focus (is
highlighted) and the right arrow or OK button is pressed, the following actions occur:
• “Display option” – enable/disable this feature
• “Test message” – view message in operation
• “Edit message” – edit the message
The user must be logged in before navigation to the “Display option” and “Edit message” pages occur. If the user is not
logged in, the user is asked to log in. The left arrow button is used to exit this page and return back to the Display Menu
page. The Home button exits this page and goes to the Home page.
The Call for Service feature is turned on (enabled) or off (disabled) by editing the “Display option” (see next figure). The up
and down arrow buttons are used to scroll to the desired setting: “Enabled” or “Disabled”. To commit the change the right
arrow button is used to tab to the “Yes” command and the OK button is pressed to save the selected setting. If the setting
should not be saved, scroll down to the “No” command and press the OK button. In both cases control returns back to the
Call for Service menu.

Changing the contents of the message is initiated by selecting the “Edit message” line (see Fig. 37). Since the first line of
the message is fixed, i.e., not editable, the input focus is positioned on the first character position of the second line. Up to
20 characters can be entered for each line. Up to 7 lines (excluding the first line) can be edited, lines 2 through 8. Lines at
the bottom that are blank are not displayed in the message. The current message text is displayed when the page is
initially entered.

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)
