Push Button Definitions

The push buttons react differently based on what mode the user is in and what screen type is currently being displayed. The following table describes this interaction. Note that this is a general guideline. Exceptions will be noted in the individual IRD specifications.

LCD Mode	Push	LCD Screen	Function
	Button	Type
VIEW	ENTER	MENU	Go to next lower level and display the first screen on that level.
		INFO	N/A
		PARAMETER	Enter EDIT mode and set cursor on first digit if alpha-numeric or
			blink entire field if field type is list select. EDIT mode is only
			entered if the user has the authorization to edit the parameter.
	ESCAPE	(All)	Go to previous (higher) level and display the current screen OR
			display the first screen at the current level if at the highest level.
			The first screen at the top level is the HOME screen. Therefore,
			pressing ESCAPE numerous times (or pressing and holding) will
			eventually return the user to the HOME screen.
	UP	(All)	N/A
	DOWN	(All)	N/A
	LEFT	(All, except	Display the previous screen at the current level OR wrap to the
		SCROLL	last screen if currently on the first screen.
		INFO)
	RIGHT	(All, except	Display the next screen at the current level OR wrap to the first
		SCROLL	screen if currently on the last screen.
		INFO)
	LEFT	SCROLL	Scrolls to the left in a scrolled information screen.
		INFO
	RIGHT	SCROLL	Scrolls to the right in a scrolled information screen.
		INFO
EDIT	ENTER	PARAMETER	If the user input is valid, the IRD accepts the changes that were
			made and enters the VIEW mode. If the input was invalid, the
			IRD flashes an “Invalid Entry” message on the LCD momentarily
			before returning to the same screen in the EDIT mode again.
	ESCAPE	PARAMETER	Abort any changes made to the parameter and enter the VIEW
			mode.
	UP	PARAMETER	List Select: Scrolls up to next value in the list or wraps if currently
			on the last item in the list.
			Alpha-numeric: Increases the value of the current field. If numeric
			and the current value is 9 (if decimal) or 0xF (if hex), the value
			will wrap to a 0. If alpha-numeric, the value will wrap to the first
			ASCII value when at 0x7F.
	DOWN	PARAMETER	List Select: Scrolls down to previous value in the list or wraps to
			the last item if currently on the first item in the list.
			Alpha-numeric: Decreases the value of the current field. If
			numeric and the current value is 0, the value will wrap to 9 (if
			decimal) or to 0xF (if hex). If alpha-numeric, the value will wrap
			to the last ASCII value when at the first.
	LEFT	PARAMETER	List Select: N/A
			Alpha-numeric: Moves to the previous digit. Wraps to the last
			digit if currently on the first.
	RIGHT	PARAMETER	List Select: N/A
			Alpha-numeric: Moves to the next digit. Wraps to the first digit if
			currently on the last.
