Important Codes: 1200. The VFR code for any altitude in the US (Refer to ICAO standards elsewhere) 7000. The VFR code commonly used in Europe (Refer to ICAO standards) 7500. Hijack code (Aircraft is subject to unlawful interference) 7600. Loss of communications 7700. Emergency 7777. Military interceptor operations (Never squawk this code) 0000. Military use Avoid selecting codes 0000, 7500, and all codes in the 7600-7777 range. These codes trigger special indicators in automated facilities. An aircraft’s transponder code is used for ATC tracking purposes, therefore exercise care when making routine code changes! Keys for Other GTX 328 Functions IDENT. Pressing the IDENT Key activates the Special Position Identification (SPI) Pulse for 18 seconds, identifying your transponder return from others on the air traffic controller’s screen. The word ‘IDENT’ will appear in the upper left corner of the display while the IDENT mode is active. VFR. Sets the transponder code to the pre-programmed VFR code selected in Configuration Mode (this is set to 7000 at the factory). Pressing the VFR Key again restores the previous identification code. If the VFR Key is disabled (dependent upon installation configuration) a ‘VFR Key Disabled’ message appears, to indicate that no operation took place. FUNC. Changes the page shown on the right side of the display. Display data includes Pressure Altitude, Flight Time, Altitude Monitor, Count Up and Count Down timers. Also displays Outside Air Temperature, Density Altitude, Contrast, and Display (dependent upon installation configuration). START/STOP. Starts and stops the Altitude Monitor, Count Up, Count Down and Flight timers. CRSR. Initiates starting time entry for the Count Down timer and cancels transponder code entry. CLR. Resets the Count Up, Count Down and Flight timers. Cancels the previous keypress during code selection and Count Down entry. Returns cursor to the fourth code digit within five seconds after entry. 8. Reduces Contrast and Display Brightness when the respective fields are displayed (dependent upon installation configuration) and enters the number eight into the Count Down timer. 9. Increases Contrast and Display Brightness when the respective fields are displayed (dependent upon installation configuration) and enters the number nine into the Count Down timer. Function Display PRESSURE ALT: Displays the altitude data supplied to the GTX 328 in feet, hundreds of feet (i.e., flight level), or meters, (dependent upon installation configuration. FLIGHT TIME: Timer start is configured as either Manual or Automatic. When Manual, displays the Flight Time, controlled by the START/STOP and CLR keys. When Automatic, the timer begins when take off is sensed. ALTITUDE MONITOR: Controlled by START/STOP Key. Activates a voice alarm and warning annunciator when altitude limit is exceeded. OAT/DALT: Displayed when the GTX 328 is configured with temperature input. Displays Outside Air Temperature and Density Altitude. COUNT UP TIMER: Controlled by START/STOP and CLR keys. COUNT DOWN TIMER: Controlled by START/STOP, CLR, and CRSR keys. The initial Count Down time is entered with the 0 – 9 keys. CONTRAST: This page is only displayed if manual contrast mode is selected during installation configuration. Contrast is controlled by the 8 and 9 keys. DISPLAY: This page is only displayed if manual backlighting mode is selected during installation configuration. Backlighting is controlled by the 8 and 9 keys. Altitude Trend Indicator When the ‘PRESSURE ALT’ page is displayed, an arrow may be displayed to the right of the altitude, indicating that the altitude is increasing or decreasing. One of two sizes of arrows may be displayed depending on the vertical speed rate. The sensitivity of these arrows is set by an authorized Garmin Aviation Service Center. The GTX 328’s options are normally set at time of installation. To request any changes of the GTX 328 parameters, contact an authorized Garmin Aviation Service Center. Timer Operation To operate the Flight Timer: 1. Press the FUNC Key until ‘FLIGHT TIME’ is displayed. 2. If the GTX 328 is configured with Automated Airborne Determination, the timer begins automatically when the unit senses that the aircraft has become airborne. The timer may be reset to zero at every take off, continue accumulating time at take off or may be controlled manually. 3. If desired, press START/STOP to pause or restart the timer. 4. Press CLR to reset the timer to zero. 5. If the timer is configured to start automatically it will stop when the Automated Airborne Determination senses that the aircraft is on the ground. To operate the Count Up timer: 1. Press the FUNC Key until ‘COUNT UP’ is displayed. 2. If necessary, press CLR to reset the Count Up timer to zero. 3. Press START/STOP to begin count up. 4. Press START/STOP again to pause the timer. 5. Press CLR to reset the timer to zero. To operate the Count Down timer: 1. Press the FUNC Key until ‘COUNT DOWN’ i...
