Setting the ATC Code

Press the ATC/FID button to select the ATC Mode. The ATC indicator is illuminated and

the display shows the last 4-digit ATC code entered. Refer to Fig 8.

Figure 8 – ATC Mode

The ATC code can be set to any values from 0000 to 7777. To set an ATC code, use the

keypad buttons 0 thru 7 to enter a 4-digit code. The new ATC code will be transmitted

after 5 seconds. If you press the IDENT button before 5 seconds has elapsed, the new

code will be transmitted immediately.

NOTE

: Keypad buttons “8 VWX” and” 9 YZ” do not operate in ATC Mode. The

display will show INVALID if you press one of these two buttons.

If you do not enter a complete 4-digit code, the display will revert back to the previous ATC

code after 5 seconds. If you enter a wrong digit, press the CLR button to erase the last digit

entered, or press and hold the CLR button to clear the entire display.

NOTE

: 5 seconds after you press the CLR button, the display will show the previously

transmitted ATC code unless you complete the code entry.

NOTE

: If you press the IDENT button while the code entered is incomplete (if the code

has less than 4 digits), the incomplete code is not transmitted and the previously

transmitted code will re-appear on the display.
