Encryption ( ): to Add or Remove Encryption
Encryption Instructions:
1. Press the rotary controller to activate and move the cursor to the icon. When the
icon starts to flash and the word “NO” appears, the encryption function is ready to
be set.
2. Press and hold the rotary controller for approximately 3 seconds until the word
changes from “NO” to “YES”.
3. Press rotary controller once to confirm and save the selected “YES” for encryption.
The transmitter now needs to be synced to the receiver using the ACT function to
apply the encryption.
NOTE:
!
Encryption is factory set by default to “NO” in the receiver (encryption OFF).
!
The transmitter can only display encryption status and cannot activate/de-
activate encryption.
!
The 128-bit encryption key is randomly generated; hence, a new, secure,
encryption key is also downloaded to a transmitter each time an ACT function is
synced successfully.
!
This means the last encrypted transmitter will work only with the encrypting
receiver. It also means that previously encrypted transmitters will not work with
the encrypting receiver even though they are on the same frequency as there
will be no audio output. This method also ensures that another similar receiver
cannot listen in to the encrypted transmitter.
