SCRAMBLER (ANALOG)/ ENCRYPTION (P25/ NXDN)Note:● The Scrambler function can be used only in Analog Conventional Operation.● In NXDN systems, there are two types of encryption, namely bit scrambling method (built-in encryption function) and AES/ DES (SCM*). In P25 systems, only AES/ DES (SCM*)encryption is available.* SCM (Secure Cryptographic Module) is a hardware cryptographic module developedby JVC KENWOOD to provide cryptographic securities for digital two way radios.● Ask your dealer for details concerning the Encryption DES/ AES settings.SECURE (ENCRYPTED) TRANSMISSIONPress the key programmed as [Scrambler/ Encryption] to switch the transceiver tosecure (encrypted) transmission.Alternatively, press the key programmed as [Menu] to enter Scrambler/ EncryptionMode using the Menu Mode.● The Scrambler indicator ( ) or Encryption indicator ( ) appears when the respectivefunction is turned ON.● Pressing the PTT switch after the Scrambler or Encryption function has been turned ONencrypts the transmitted signal.● Each group member must activate their respective Scrambler/ Encryption functions todescramble/ decrypt the received signals.SELECTING THE SCRAMBLER CODE1 Press the key programmed as [Scrambler/ Encryption Code] to enterScrambler/ Encryption Code Mode.Alternatively, press the key programmed as [Menu] to enter Scrambler/ Encryption CodeMode using the Menu Mode.2 Press the [J] and [K] keys to increase or decrease the Scrambler code.● Up to 16 Scrambler codes can be used.● Each group member must use the same code in order for the transceivers todescramble the received signals.3 Press the [ ] key to set the new Scrambler code.SELECTING THE ENCRYPTION KEY1 Press the key programmed as [Scrambler/ Encryption Code] to enterScrambler/ Encryption Code Mode.Alternatively, press the key programmed as [Menu] to enter Scrambler/ Encryption CodeMode using the Menu Mode.2 Select the new Encryption key using the [J] and [K] keys.● Up to 32 Encryption keys can be used. One of these keys will be used duringtransmission.● When a call is received, the transceiver will decrypt the call as long as the receivedEncryption key is in the Multi Key List.3 Press the [ ] key to set the new Encryption key.Note:● To restore to the default Encryption key, select “Preset”. However, if you delete theEncryption key, it will not be recovered.35
