Selective Calling (Selcall)
Selective calling (Selcall) allows an individual radio to call another radio using a sequence of tones, usually presented to the user as a series of 5 numbers. UHF CB radios can be set to be completely silent until they receive a series of tones matching a pre-programed sequence. Radios which have this feature usually indicate that a call has been received by emitting a number of beeps and by opening the squelch.

Famous quotes containing the words selective and/or calling:
“The selective memory isn’t selective enough.”
—Blake Morrison (b. 1950)
“I keep having the same experience and keep resisting it every time. I do not want to believe it although it is palpable: the great majority of people lacks an intellectual conscience. Indeed, it has often seemed to me as if anyone calling for an intellectual conscience were as lonely in the most densely populated cities as if he were in a desert.”
—Friedrich Nietzsche (1844–1900)
