5.1.3 Code Selection

Code selection is done with eight keys (0 - 7) that provide 4,096 active identification codes. Pushing one
of these keys begins the code selection sequence. The new code is not activated until the fourth digit is
entered. Pressing the CLR key moves the cursor back to the previous digit. Pressing the CLR key when
the cursor is on the first digit of the code, or pressing the CRSR key during code entry, removes the
cursor and cancels data entry, restoring the previous code. You may press the CLR key up to five
seconds after code entry is complete to return the cursor to the fourth digit. The numbers 8 and 9 are not
used for code entry, only for entering a Count Down time, contrast and display brightness, and data
selection in the Configuration mode.
The selected identification code should be entered carefully, either one
assigned by air traffic control for IFR flight or an applicable VFR
transponder code.
• Important Codes:
1200  VFR code for any altitude in the US (Refer to ICAO standards elsewhere)
