TRANSPONDER OPERATION
The transponder receives interrogations from surrounding aircraft
and from ATC and then transmits replies. The transponder application
is the first screen on the left side of the display as indicated by the
application indicator. See Figure 2-5 and the functional description
below for operating instructions.
Squawk Code
When the Squawk Code text is tapped, the Squawk Code Edit Screen
is shown. See Figure 2-6. The current Squawk Code continues to be
transmitted until the last digit of the new Squawk Code is entered.
The edit mode is cancelled by tapping the Squawk Code before the
fourth digit is entered, or after 5 seconds of inactivity, or if a TAS alert
occurs.
