SCRAMBLER (ANALOG/ LTR)/ ENCRYPTION (NXDN/ DMR) Note: ● The Scrambler function can be used only in Analog Conventional and LTR Trunking Operation. ● The following types of encryption are available depending on the system used. NXDN : Bit scrambling (built-in encryption function), 56-bit DES and 256-bit AES DMR : Bit scrambling (built-in encryption function), 56-bit DES, 256-bit AES and Enhanced Encryption ● Ask your dealer for details concerning the Encryption DES/ AES and Enhanced Encryption settings. SECURE (ENCRYPTED) TRANSMISSION Press the button programmed as [Scrambler/ Encryption] to switch the transceiver to secure (encrypted) transmission. Alternatively, press the button 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. * The indicator displayed varies depending on the type of Encryption function activated.

Alternatively, press the button programmed as [Menu] to enter Scrambler/ Encryption Code Mode using the Menu Mode. 2 Press the [J] and [K] buttons to increase or decrease the Scrambler code. ● Up to 16 Scrambler codes can be used. 3 Press the [ ] or [ ] button to set the new Scrambler code. SELECTING THE ENCRYPTION KEY 1 Press the button programmed as [Scrambler/ Encryption Code] to enter Scrambler/ Encryption Code Mode. Alternatively, press the button programmed as [Menu] to enter Scrambler/ Encryption Code Mode using the Menu Mode. 2 Select the new Encryption key using the [J] and [K] buttons. ● Up to 32 Encryption keys can be used. One of these keys will be used during transmission. 3 Press the [ ] or [ ] button to set the new Encryption key. Note: ● In NXDN systems, a key error will be displayed when a Key ID which is 0x40 and above is selected for the AES/DES encryption function. ● To restore to the default Encryption key, select "Preset".

Enhanced Encryption
●
Ask your dealer for details concerning the Encryption DES/ AES and Enhanced Encryption
settings.
SECURE (ENCRYPTED) TRANSMISSION
Press the button programmed as
[Scrambler/ Encryption]
to switch the transceiver
to secure (encrypted) transmission.
Alternatively, press the button 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.
*
The indicator displayed varies depending on the type of Encryption function activated. Refer to
“INDICATOR LIST” {p. 68} .
