Turn it on and then say "roger .. how's that?"


There's no point in asking an aircraft to reset a transponder that hasn't
been turned on. An aircraft that is instructed to recycle the transponder
is usually one that has previously supplied a good beacon target. When an
aircraft departs and no beacon target is seen where one should be seen the
instruction is usually "verify you're squawking NNNN".
