Abnormal Operation; Reversionary Mode; Stuck Microphone; Com Tuning Failure - Garmin G2000 Cockpit Reference Manual

NOTE: The Cessna Corvalis T240 Airplane Flight Manual (AFM) always takes
precedence over the information found in this section.

REVERSIONARY MODE

Should a system detected failure occur in either display, the G2000 automatically
enters reversionary mode. In reversionary mode, critical flight instrumentation is
combined with engine instrumentation on the remaining display.
If the system fails to detect a display problem, Reversionary Mode may be manually
activated by pressing the DISPLAY BACKUP Button on the instrument panel.
Pressing this button again deactivates Reversionary Mode.

STUCK MICROPHONE

If the push-to-talk (PTT) Key becomes stuck, the COM transmitter stops
transmitting after 35 seconds of continuous operation. An alert appears on the
Touchscreen Controller to advise the pilot of a stuck microphone.
The MIC Button Annunciator flashes as long as the PTT Key remains stuck.

COM TUNING FAILURE

In case of a COM system tuning failure, the emergency frequency (121.500 MHz)
is automatically tuned in the radio in which the tuning failure occurred. Depending
on the failure mode, a yellow X may appear on the frequency display. The emergency
frequency (121.500 MHz) may also be tuned by pressing the PFD Settings > Other
PFD Settings > COM 121.5.
