The GTX 330 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.

OFF  Powers off the GTX 330. Pressing STBY, ON, or

ALT key powers on the transponder displaying the last

active identification code.

STBY  Selects the standby mode. When in standby mode,

the transponder will not reply to any interrogations.

ON  Selects Mode A. In this mode, the transponder replies to

interrogations, as indicated by the Reply Symbol (

information.

ALT  Selects Mode A and Mode C. In ALT mode, the transponder replies to

identification and altitude interrogations as indicated by the Reply Symbol (

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 is done with eight keys (0 – 7) providing 4,096 active identification codes.

Pushing one of these keys begins the code selection sequence. Digits that are not yet entered

appear as dashes. The new code is activated when 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, and for adjusting contrast and display

brightness.
