the Transponder Data Box. In
Ground Mode, the transponder does not allow Mode A and Mode C replies,
but it does permit acquisition squitter and replies to discretely addressed Mode S interrogations.
When Standby Mode has been selected on the ground, the transponder can be returned to Ground Mode
by pressing the
