4. Procedure
Subtask 34-55-00-710-055-A

A. Operational Test of the VOR/MKR

ACTION	RESULT
1.On the RMP1 (RMP2):
push the NAV pushbutton switch.	On the RMP, the green LED on this pushbutton switch comes on.
set the frequency of the VOR1 (2) local station VOR-Frequency and Course Selection ON A/C NOT FOR ALL VOR-Frequency and Course Selection ON A/C NOT FOR ALL VOR-Frequency and Course Selection ** ON A/C NOT FOR ALL	The frequency comes into view in the left window of the RMP
2.On the center pedestal, on one ACP :
set the VOR1 reception.	In the loud speakers, you must hear the Morse signal of the set station.
3.On the RMP1 (RMP2):
push the NAV pushbutton switch.	The green LED on this pushbutton switch goes off.
