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)
“It is as real
as splinters stuck in your ear. The noise we steal
is half a bell. And outside cars whisk by on the suburban street
and are there and are true.
What else is this, this intricate shape of air?
calling me, calling you.”
—Anne Sexton (1928–1974)
