[. . . ] You agree not to export or re-export the Software to any country in violation of the export control laws of the United States of America. October 2002 Part Number 190-00187-00 Rev. B Printed in USA Limited Warranty This GARMIN product is warranted to be free from defects in materials or workmanship for one year from the date of purchase. Within this period, GARMIN will at its sole option, repair or replace any components that fail in normal use. Such repairs or replacement will be made at no charge to the customer for parts or labor, provided that the customer shall be responsible for any transportation cost. [. . . ] CAUTION: The GTX 327 should be turned off before starting or shutting down aircraft engine(s). The GTX 327 transponder is powered on by pressing the STBY, ALT or ON keys, or by a remote avionics master switch (if applicable). After power on, a start-up page is displayed while the unit performs a self test. If the unit detects an internal failure, the screen displays SELF TEST FAILED. (See your GARMIN dealer for software upgrades. ) Mode Selection Keys OFF Powers off the GTX 327. Pressing STBY, ON or ALT key powers on the transponder displaying the last active identification code. When in standby mode, the transponder will not reply to any interrogations. In this mode, the transponder replies to interrogations, as indicated by the Reply Symbol ( ). In ALT mode, the transponder replies to identification and altitude interrogations as indicated by the Reply Symbol ( ). Replies to altitude interrogations include the standard pressure altitude received from an external altitude source, which is not adjusted for barometric pressure. The ALT mode may be selected in aircraft not equipped with an optional altitude encoder; however, the reply signal will not include altitude information. Any time the function ON or ALT is selected 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 Selection Code selection is done with eight keys (0 ­ 7) providing 4, 096 active identification codes. 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. An aircraft's transponder code is used for ATC tracking purposes, therefore exercise care when making routine code changes. Keys for Other GTX 327 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 1200 at the factory). Display includes Pressure Altitude, Flight Time, Count Up and Count Down timers. START/STOP Starts and stops the Count Up, Count Down and Flight timers. CRSR Initiates starting time entry for the Count Down timer and cancels transponder code entry. Cancels the previous keypress during code selection and Count Down entry. [. . . ] When a field is highlighted, use the 8 or 9 keys to select changeable fields or the 0 - 9 keys to enter numeric data. Press the CRSR key to confirm list selections. 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 rate of climb/descent. The sensitivity of these arrows is set using the GTX 327 Configuration Mode vertical speed rate. Timer Operation To operate the Flight Timer: 1. [. . . ]
