Transponder  function  is  displayed  on  three  levels  of  softkeys  on  the  PFD:  Top-level,  Transponder/Traffic

Selection, and Mode Selection or Code Entry. When the top-level XPDR/TFC Softkey is selected, the Function
Select softkeys appear:  XPDR1, XPDR2 (if TCAS XPDR2 option is loaded), MODE, TCAS, CODE, IDENT, 
BACK.

When the MODE Softkey is selected, the Mode Selection softkeys appear:  STBY, ON, ALT, TA ONLY, TA/

RA, BACK.

When the CODE Softkey is selected, the number softkeys appear: 0,  1,  2,  3,  4,  5,  6,  7,  IDENT,  BKSP, 

BACK.  The digits 8 and 9 are not used for code entry.  Selecting the numbered softkeys in sequence enters 
the transponder code. If an error is made, selecting the BKSP Softkey moves the code selection cursor to the 
previous digit.  Selecting the BKSP Softkey again moves the cursor to the next previous digit.

Selecting the BACK Softkey returns to the previous level softkeys.

The code can also be entered with the FMS Knob on either PFD. Code entry must be completed with either

the softkeys or the FMS Knob, but not a combination of both.

Selecting the IDENT Softkey while in Code Selection initiates the ident function and reverts to the top-level

softkeys.

After 45 seconds of transponder control inactivity, the system reverts back to the top-level softkeys.

Selecting the 

BACK Softkey

returns to the top-level softkeys.
