2. Select the VFR code as required.
3. Push the Ident (IDT) button, or wait 3 seconds, or rotate the

and when pushed and held for more than four seconds switches the
TCAS traffic display to the FL (flight level) display function. To select
an ATC code, momentarily push this knob to start the left hand digit
in the ATC code flashing, twist the knob to change the number.
Momentarily push the knob again to move the flashing digit one
space to the right and twist the knob to change the digit. Repeat for
the third and fourth digit of the ATC code. The flashing digit will stop
flashing 3 seconds after the last change.
The traffic display switches to the FL (flight level) display function
when the inner knob is pressed in for more than four seconds. The
relative altitude tags are replaced with absolute altitude (FL) tags.
The traffic display will revert to relative altitude after 15 seconds.
