If the status of Scrambler/Encryption (to be enabled or disabled) is switched for the channel where “Mixed” is configured
in
Channel Type
, the status of Scrambler/Encryption (to be enabled or disabled) applies for a channel according to the
mode (either Analog or P25) configured in
Transmit Mode
of the channel.

Configuring the Encryption Key Data Used for
Communications (P25 Conventional System Only)
The encryption key data used for communications can be configured by selecting the key data from the Multi-key List.
The transceiver can have a maximum of 32 Encryption Keys (Key ID and Key Data) if SCM is used. Also, the transceiver
can have a maximum of 4 Encryption Keys (Key ID and Key Data) if Built-in DES is used. However, only one of these
Encryption Keys can be used for transmission.
An Encryption Key used for transmission can be configured using KPG-D1/ D1N for a P25 digital channel by selecting the
Encryption Key from the Multi-Key List. (Refer to
On a channel in a P25 Conventional system configured as below, the Encryption Key configured for the channel can be
changed by operating the transceiver:
0
Key Strapped: Select
0
Talkgroup ID List Number: None
The transceiver needs to enter Scrambler/ Encryption Code Mode in order to change an Encryption Key. In Scrambler/
Encryption Code Mode, a Multi-key corresponding to the Encryption Key data used for transmission can be selected from
the Multi-Key List configured for the transceiver.
Pressing and holding the
Scrambler/Encryption
key or pressing the
Scrambler/Encryption Code
key places the
transceiver in Scrambler Encryption Code Mode.
Or, the transceiver can also enter Scrambler/Encryption Code Mode by pressing the
Menu
key to place the transceiver in
Menu Mode and then selecting “Scrambler/Encryption Code”. (Refer to Common FUNC
