Encryption 129About encryptionThe encryption feature is available for digital anddual-mode channels only.To make communications with other users on yoursystem completely private, your radio may be able toencrypt outgoing calls, using a confidential encryptionkey. The radio receiving your call must have the sameencryption key installed before it can hear yourencrypted call.About the proper key detect featureYour radio may be programmed with ‘proper keydetect’. This means that you can only hear anencrypted call if the key used to encrypt the incomingcall matches the key used to encrypt your outgoingcalls on that channel.Note that encryption does not need to be turned ‘on’for the radio to unmute.For example, you are encrypting your outgoing callsusing encryption key 7. Although key 1 and key 2 arealso stored in your radio, your radio has beenprogrammed so that it will only unmute for incomingcalls encrypted using key 7.Encrypting callsYour radio may be able to turn encryption on and off.While encryption is on, your outgoing calls areencrypted on channels programmed for encryption,and the encryption icon remains in the display.This setting only affects outgoing calls. Incoming callswill still be decoded by your radio so long as the keyrequired to decode the call is stored in your radio.
