VFR CODE
NOTE: The pre-programmed VFR code is set at the factory to 1200.
The VFR code can be entered either manually, each digit at a time, or by selecting the XPDR Softkey,
then the
VFR Softkey. When the VFR Softkey is selected, the pre-programmed VFR code is automatically
displayed in the code field of the Transponder Data Box.
Selecting the VFR Softkey again restores the previous identification code.

• 1200 – VFR code in the U.S. (refer to ICAO standards for VFR codes in other countries)

IDENT FUNCTION
NOTE: In Standby Mode, the IDENT Softkey is inoperative.
Selecting the IDENT Softkey sends an ID indication to Air Traffic Control (ATC). The ID return distinguishes
the aircraft’s own transponder from all others on the air traffic controller’s radar screen.
The IDENT Softkey appears in all levels of transponder softkeys. When the IDENT Softkey is selected, a green
IDENT indication is displayed in the mode field of the Transponder Data Box for a duration of 18 seconds.
When the
IDENT Softkey is selected while in Mode or Code Selection, the system reverts to the top-level
softkeys.
