To All Forum Members,
Chuck, I did as you said with the “AUX-1 and 2” keys, and when I depressed the “AUX-1” key and then the numeral “7” key the Tower Com. said;
“Chessie three-three-twelve, please, standby.”
Otherwise, as only stated in the ‘Instruction Booklet’, is to just depress the numeral “7” key and Tower Com. says;
“Chessie three-three-twelve you are cleared outbound.”
There, may be other announcements, but I have to play around to find the correct combination.
Thank You,
Ralph
