CODE SELECTION
Pressing the Code Selector/Data Entry Switch once enables Transponder Code entry. The left most code digit
will begin flashing. Turning the switch selects the code and pushing the switch again moves to the next digit
from left to right. Once code selection has started, all four digits must be set before the code entry is completed.
A total of 5 pushes completes the code entry process. If the switch is inadvertently pressed, it will stop the code
entry process automatically in 10 seconds. The VFR code can subsequently be recalled automatically by
pressing the VFR button. Code entry can not be started if the AT165 is in setup, Count Down Timer set, or
Altitude Buffer set modes.
