4. Procedure
Subtask 31-39-00-710-052-A ** ON A/C NOT FOR ALL

A. Operational Check of the of Recording Relay Logic

ACTION	RESULT
1.On overhead control and indicating panel 21VU: Push the RCDR/GND CTL pushbutton switch.	On the RCDR/GND CTL pushbutton switch: The blue ON legend comes on. In the headset: Make sure that you hear your voice recorded by the cockpit microphone. Make sure that you hear the synchronization tone.
2.On the overhead panel, on panel 49VU: Open circuit breaker 2KS1.
3.On the rear panel, on panel 121VU: Open circuit breaker 4KS1.
NOTE: Engine 1 running is simulated.	On the RCDR/GND CTL pushbutton switch: The blue ON legend goes off. In the headset: Make sure that you hear your voice and synchronization tone.
4.On the overhead panel, on panel 49VU: Close circuit breaker 2KS1.
5.On the rear panel, on panel 121VU: Close circuit breaker 4KS1.
NOTE: Engine 1 running simulation is stopped.	In the headset: After approximately 5 minutes after the Engine 1 simulation is stopped, make sure that you can not hear your voice and synchronization tone.
6.On overhead control and indicating panel 21VU: Push the RCDR/GND CTL pushbutton switch.	On the RCDR/GND CTL pushbutton switch: The blue ON legend comes on. In the headset: Make sure that you hear your voice recorded by the cockpit microphone. Make sure that you hear the synchronization tone.
7.On the overhead panel, on panel 49VU: Open circuit breaker 2KS2.
8.On the rear panel, on panel 121VU: Open circuit breaker 4KS2.
