F F NOTE: The GTX 320A owner accepts all responsibility for obtaining the proper licensing before using the transponder. NOTE: The coverage you can expect from the GTX 320A is limited to "line of sight". Low altitude or aircraft antenna shielding by the aircraft itself may result in reduced range. It may be possible to minimize antenna shielding by locating the antenna where dead spots are only noticed during abnormal flight attitudes. CAUTION: The GTX 320A should be turned off before starting or shutting down aircraft engine(s). I Ident Button Reply Light Code Selection Knobs Function Selection Knob Function Selector Switch: The function selector switch is a five position rotary switch. The five positions are: OFF-Turns off all power to the GTX 320A (the unit should be turned off before starting aircraft engine(s). SBY-Turns the transponder on, but when in SBY the unit will not reply to any interrogations. ON-The transponder transmits the aircraft's identification code (Mode A) but does not include altitude information. ALT- The transponder transmits the aircraft's identification code, in Mode A and pressure altitude (29. 92 inches Hg) information in Mode C provided the aircraft is equipped with an optional altitude encoder. The unit is normally operated in the ALT position at all times unless otherwise directed by ATC. The function selector is spring loaded and must be held in TST position. Any time the function switch is in the ON or ALT position the transponder becomes an active part of the Air Traffic Control Radar Beacon System (ATCRBS). The transponder also responds to interrogations from TCAS equipped aircraft. Code Selector The code selector consists of four, eight-position switches that provide 4, 096 active identification codes. [. . . ] The reply light remains illuminated during the IDENT time interval and during TST function.
