Open switch 3 to battle the burglar there then push no. 2 and no. 1 to battle another burglar and find a full heal. then go East and face the grunt, pull the switch and go in.

You probably should heal your Pokémon then go back to the Radio Tower. Go up to 3F and put the card key into the slot, then battle the grunt and go up. Beat all of the trainerson 4F then go to 5F, beat the two Executives then the real director comes in and gives you the Silver or Rainbow Wing, before you go, pick up the Ultra Ball then leave, Mary in studio 2 will give you the Pink Bow for normal type moves, the Green haired girl on Level 3 will give you TM11, now go and check the lottery corner and then go to Ecruteak City.
