Narrative:

Software problem -- ATCT controller attempting to transfer control of ASR-9 equipment from ATCT to RAPCON (this is accomplished by entering a #2 on ASR-9 computer). Accidently entered #3 which turns the radar antenna off with 1 keystroke. This event has happened several times. There needs to be some type of safeguard to prevent reoccurrence, ie, 'are you sure?'
