4. Procedure
Subtask 34-14-00-740-065-A ** ON A/C NOT FOR ALL

A. Read the CFDIU for the IR INPUT STATUS

NOTE: This test is for the system 1. For the systems 2 and 3, use the indications between the parentheses.
The actions and the results of this procedure occur on the MCDU used.

ACTION	RESULT
On the center pedestral, on one MCDU:
1.Get the SYSTEM REPORT/TEST/NAV page (Ref. AMM TASK 31-32-00-860-001).	The SYSTEM REPORT/TEST/NAV page comes into view.
2.On the NAV page
Push the line key adjacent to the IR1 (IR2) (IR3) indication	the IR1 (IR2) (IR3) page comes into view.
3.Push the line key adjacent to the INPUT STATUS indication	the INPUT STATUS page 1/6 comes into view with the current on-the-ground status of the IR1 (IR2) (IR3) inputs.
4.Push the NEXT PAGE function key to get the INPUT STATUS page 2/6 to 6/6	the related pages come into view.
5.Push the line key adjacent to the RETURN indication	the test procedure stops.
