— possibility of enciphering the voice transmitted over the air. This function is primarily designed to protect against unauthorized listening: only a walkie-talkie equipped with the same scrambler as the one transmitting can normally reproduce an encrypted transmission, while on the open air, an outside listener will receive only a set of meaningless noise. Note that legal use of a scrambler walkie-talkie may require a license.
