Operation Manual

SCRAMBLER (ANALOG)/ ENCRYPTION (P25/ NXDN)
Note:
●
The Scrambler function can be used only in Analog Conventional and Analog Trunking
Operation.
●
In NXDN systems, there are two types of encryption, namely bit scrambling method (built-
in encryption function) and AES (SCM*)/ DES (built-in-DES or SCM*). In P25 systems,
only AES (SCM*)/ DES (built-in-DES or SCM*) encryption is available.
* SCM (Secure Cryptographic Module) is a hardware cryptographic module developed
by JVC KENWOOD to provide cryptographic securities for digital two way radios.
●
The transceiver includes a built-in DES that allows you to set up to four Encryption keys.
●
SCM and the built-in DES cannot be operated simultaneously.
●
Ask your dealer for details concerning the Encryption DES/ AES settings.
SECURE (ENCRYPTED) TRANSMISSION
Press the key programmed as [Scrambler/ Encryption] to switch the transceiver to
secure (encrypted) transmission.
Alternatively, press the key programmed as [Menu] to enter Scrambler/ Encryption
Mode using the Menu Mode.
●
The Scrambler indicator (
) or Encryption indicator ( ) appears when the respective
function is turned ON.
●
Pressing the PTT switch after the Scrambler or Encryption function has been turned ON
encrypts the transmitted signal.
●
Each group member must activate their respective Scrambler/ Encryption functions to
descramble the received signals.
SELECTING THE SCRAMBLER CODE
1
Press the key programmed as [Scrambler/ Encryption Code] to enter
Scrambler/ Encryption Code Mode.
Alternatively, press the key programmed as [Menu] to enter Scrambler/ Encryption Code
Mode 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 to
descramble the received signals.
3
Press the [
] or [ ] key to set the new Scrambler code.
SELECTING THE ENCRYPTION KEY
1
Press the key programmed as [Scrambler/ Encryption Code] to enter
Scrambler/ Encryption Code Mode.
Alternatively, press the key programmed as [Menu] to enter Scrambler/ Encryption Code
Mode 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 during
transmission.
●
When a call is received, the transceiver will descramble the call as long as the received
code is in the encryption list.
