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)
“When I was in high school I thought a vocation was a particular calling. Here’s a voice: “Come, follow me.” My idea of a calling now is not: “Come.” It’s like what I’m doing right now, not what I’m going to be. Life is a calling.”
—Rebecca Sweeney (b. 1938)
