    ATCRBS TRANSPONDER KT 76C To prevent rf interference, the antenna must be physically mounted a mini- mum distance of three feet from the KT 76C and the wiring harness. The transponder antenna should be mounted a minimum of six feet away from the DME antenna, four feet from the ADF sense antenna, and three feet from TCAS antennas.

  • Page 46: Standby

    ATCRBS TRANSPONDER KT 76C Standby - The unit is energized, but is inhibited from replying to any interrogation. “SBY” is annun- ciated on the display in this mode. The altitude display is blank (see Figure 3-2). FIGURE 3-2 Standby TST - The unit will illuminate all segments. The unit will remain in TST mode until the mode se- lection is changed (see Figure 3-3).
