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)
“Every man who has lived for fifty years has buried a whole world or even two; he has grown used to its disappearance and accustomed to the new scenery of another act: but suddenly the names and faces of a time long dead appear more and more often on his way, calling up series of shades and pictures kept somewhere, “just in case” in the endless catacombs of the memory, making him smile or sigh, and sometimes almost weep.”
—Alexander Herzen (1812–1870)
