Encrypted radios provide increased privacy for conversations by jumbling
speech so that only radios with the right hardware and settings can
reconstruct it. The diagram below shows a typical radio system comprising
portable radios, mobile radios, base stations or repeaters.

Whether or not a radio transmission is encrypted is the user's choice. When
the encryption mode is selected, the radio sends and receives encrypted calls
to and from other radios with compatible encryption module and settings.
However, even when encryption is not selected, an encryption-enabled
radio will always decode encrypted communication from any radio with
compatible modules and settings.
Note
When modules or settings are incompatible, communication is
reduced to unintelligible noise.
