4. Procedure
Subtask 31-60-00-710-059-A ** ON A/C NOT FOR ALL

A. Automatic PFD/ND Transfer

NOTE: This test is for the CAPT side. For the F/O side, you can use the indications between parentheses.

ACTION	RESULT
1.On panel 301VU (500VU):
Set the PFD potentiometer to OFF.	The PFD stops and the PFD image moves to the ND.
Set the PFD potentiometer to the center position.	The message SELF TEST IN PROGRESS (MAX 40 SECONDS) comes into view. The ND image then comes back on the PFD.

B. Manual PFD/ND Transfer

NOTE: This test is for to the CAPT side. For the F/O side, you can use the indications between parentheses.

ACTION	RESULT
1.On panel 301VU (500VU):
Push and release the PFD/ND/XFR pushbutton switch.	On the PFD: * The ND image comes into view. On the ND: * The PFD image comes into view.
Push and release the PFD/ND/XFR pushbutton switch again.	The PFD and ND images go back to the initial positions.

Subtask 31-60-00-710-061-A ** ON A/C NOT FOR ALL

C. Manual ECAM/ND Transfer

ACTION	RESULT
1.On the center pedestal, on SWITCHING panel 8VU:
Set the ECAM/ND/XFR selector switch to CAPT.	On the lower ECAM DU, the message "ECAM ON ND" comes into view and the system page comes into view on the CAPT ND.
Set the ECAM/ND/XFR selector switch to F/O.	On the lower ECAM DU, the message "ECAM ON ND" comes into view and the system page comes into view on the F/O ND.
Set the ECAM/ND/XFR selector switch to NORM.	The DUs go back to the initial configurations.
