Setting Encryption

The XD-V75 Digital Wireless microphone system permits a unique 24-bit encryption code to be

applied to the audio coming from the transmitter, creating a secure link between it and the associated

receiver – over 16 million codes are possible. Encryption prevents the audio signal from being captured

and deciphered when wireless is being used during conﬁdential meetings and proceedings. The audio

entering the microphone element is encoded within the transmitter, and is decoded within the receiver;

the radio signal in between is secure.

The encryption code is entered into the transmitter ﬁrst, and then is transferred to the associated

receiver. Make sure that you have already set both to the same frequency.

Note, When using the

“Send” crypto key function both transmitter and receiver will need to be set to the same channel and

communicating in non-Crypto mode before this feature can be used. With the transmitter on, press and

hold the

SELECT button to go to the channel page, and then press the button three more times to go to

the [CRYTPTO] page. The encryption mode is either [OFF] or [ON], and the word will ﬂash; press

ON/

MUTE on the handheld or VALUE on the beltpack to switch between them. Choose [ON] to set a code.

Note, The transmitter will begin transmitting in encrypted mode when [ON] is selected and setup mode

is exited. If you are going through the edit screens and do not want to change the current encryption

setting, pressing the

SELECT button again without pressing ON/MUTE or VALUE will bypass this page,

leaving encryption in its current off or on state, and go on to the next edit page. To turn off encryption,

go to the [CRYPTO] page, press the

ON/MUTE or VALUE button to go to [OFF], and press the SELECT

button to exit. In a few moments, the system will return to the unencrypted transmission mode.
