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. Important Codes: 1200 7000 7500 7600 7700 7777 The VFR code for any altitude in the US (Refer to ICAO standards elsewhere) The VFR code commonly used in Europe (Refer to ICAO standards) Hijack code (Aircraft is subject to unlawful interference) Loss of communications Emergency Military interceptor operations (Never squawk this code) 0000 Military use (Not enterable) Avoid selecting code 7500 and all codes in the 7600-7777 range.
