Subtask 23-13-00-710-050-A ** ON A/C NOT FOR ALL

A. Operational Test of the Radio Management

ACTION	RESULT
1.On the RMP1:
Set the ON/OFF selector switch to ON.	The RMP shows the last frequencies and the last function used.
Push the VHF1 pushbutton switch.	The green LED on this pushbutton switch comes on.
In the STBY/CRS display window, with the dual selector knob, set the frequency of a station that transmits.
Start this frequency. To do this, push the transfer pushbutton switch (double arrow) between the two windows.	In the ACTIVE display window, the frequency set comes into view.
2.On the RMP2:
Set the ON/OFF selector switch to ON.	The RMP shows the last frequencies and the last function used.
Push the VHF1 pushbutton switch.	The ACTIVE display window shows the same frequencies as the RMP1. The green LED on this pushbutton switch comes on. On the RMP1 and the RMP2: The SEL indicator light (amber LED) is on.
In the STBY/CRS display window, set a new frequency with the dual selector knob.
Start this frequency. To do this, push the transfer pushbutton switch (double arrow) between the two windows.	In the ACTIVE display window, the frequency set comes into view.
