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)
“[T]he most artful method [of courtship] would be this, to tell her that what she doth not possess is useless and contemptible, that weakness and imperfection is the perfection of a woman, that I am stark mad in love with ignorance; and thus shall I allure her by calling her [a] fool.”
—Sarah Fielding (1710–1768)
