RECORDER PANEL
GROUND CONTROL
The CVR is automatically energized in flight and on
ground when at least one engine is running and for 5
minutes after the last engine is shut down.
For manual control, on the ground, the CVR has to be
energized by pressing the ground control (GND CTL)
pushbutton on the recorder (RCDR) panel.
CVR TEST
When the CVR TEST pushbutton is pressed, either on
ground or in flight, a test tone is generated 4 times
for approximately 0.8 seconds.
A headset connected to the CVR HEADSET jack mounted
on the cockpit maintenance panel enables monitoring.
CVR ERASE
The CVR ERASE pushbutton is used for manual erasure
of the recording, only on ground with parking brake
applied.
It must be pressed for at least 2 seconds.
For complete manual erasure of the recording, the CVR
has to be energized.
