Operation
Squawk VFR Button
Tap the Squawk VFR toggle button to change the transponder squawk
code to a predefined (1200) VFR value. The value shown on the button
is the code that is activated when the button is tapped. A second press
reverts the transponder to the previous squawk code.
MSG Button
If a new message is available a flashing MSG button is shown on the
left screen. Tap the MSG button to view fail or degraded messages
during normal operation.
Once the messages in the message window have been viewed, the
MSG button will stop flashing. When all messages have cleared, the
MSG button is removed from the screen. On the Message window tap
the Done button to return to the previously viewed screen.
Refer to the Chap. 5 (Troubleshooting) for corrective actions.
ON-GND Indicator
The ON-GND indicator provides the pilot a notification that the
transponder is operating in the on-ground mode (does not reply to
all-calls).
System Test Button
The System Test button is available only when the aircraft is on the
ground. Tapping the button initiates the Test. During the System Test
the user functions are disabled and the right screen shows a preset
traffic display with the message “Self Test In Progress” at the top of the
screen. See Figure 2-7.
The left screen shows the system affect of the tests results on the
functional areas of the system.
Note – Functions that are not part of the installation are not shown.
Note - Individual test failures are recorded in the fault log. (Accessible
to service personnel only.)
The unit returns to normal operation if no failures are detected within
5 seconds.
