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

Softkey during code selection reverts to the Mode Selection Softkeys. Pressing the
BACK
Softkey during mode selection reverts to the top-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.
Pressing the
IDENT
Softkey while in Mode or 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 and activating Transponder 1 or Transponder 2:
1)
Press the
XPDR
Softkey to display the Transponder Mode Selection Softkeys.
2)
Press the
XPDR1
or
XPDR2
Softkey to select and activate the other transponder.
When turning on the G1000 for use, the system activates Transponder 1 as the default unit, regardless of
which transponder was active prior to shutdown. When switching between Transponder 1 and Transponder 2,
the code and mode remain the same. If a new code is entered in the active transponder, switching transponders
does not bring back the previous code.
