Using the Encrypted
Transmission Function
This receiver is capable of receiving scrambled signals
from Sony digital wireless transmitters. This function
prevents hacking of the signal.
To use this function, select one of the following encrypted
transmission modes:
Encryption key modes (SECURE KEY / AES256):
An encryption key is automatically generated by the
transmitter and used by both the transmitter and receiver in
these one-to-one encrypted transmission modes.
The SECURE KEY mode is compatible with first and
second generation DWX-series devices.
The AES256 mode uses AES 256-bit encryption for a
higher level of security in transmissions.
Password mode: You choose a password of up to eight
characters that can be set for multiple transmitters and
receivers. This enables encrypted transmission to be
conducted within a group.
Make sure the same mode is set on the transmitter and
receiver.
Using secure key mode (SECURE KEY)
Use this mode for one-to-one encrypted transmission
between one transmitter and one receiver.
An encryption key that cannot be read from the outside is
automatically generated by the transmitter. This key is
transmitted to the receiver through the RF REMOTE
function, enabling encrypted transmission to take place.
The encryption key used by the transmitter and receiver is
newly generated for each key transmission, resulting in
highly secure communication.
The encryption key used between the transmitter and the
receiver is saved when the power is turned off, so the
encrypted transmission can be resumed the next time the
power is turned on.
1 Preparing the receiver (this unit)
1 With the ENCRYPTION indication on (in the
RX1/2 menu), hold down the SET button until the
item to be set flashes.
2 Press the + or – button repeatedly to select
SECURE KEY or AES256, and then press the SET
button.
2 Preparing the transmitter
Set SECURE KEY or AES256 on the transmitter that
will transfer the encryption key.
For details on transmitter operations, refer to the
operating instructions supplied with the transmitter.
3 Exchanging the encryption key
On the receiver, select REMOTE (wireless remote) as
the method for encryption key exchange.
When the RF REMOTE function is off, REMOTE
cannot be selected.
If the transmitter does not support AES256, select
SECURE KEY.
For details, check the operating instructions included
with the transmitter you want to pair with the receiver.
The receiver searches for a transmitter that it has been
paired with. After the receiver detects the transmitter,
the transmitter exchanges the encryption key with the
receiver and encrypted transmission begins.
Using password mode (PASSWORD)
Set this mode when multiple transmitters are paired with
multiple receivers for encrypted transmission.
If the transmitters and receivers are set with the same user-
designated password, the audio signal can be decoded.
This mode is useful when multiple transmitters and
receivers are used as a single group, or when the audio
signal from one transmitter is received by multiple
receivers at the same time.
1 With the ENCRYPTION indication on (in the RX1/2
menu), hold down the SET button until the item to be
set flashes.
2 Press the + or – button repeatedly to select
PASSWORD, and then press the SET button.
3 Enter a password of up to 8 characters on the receiver.
+: The first press on the + button displays the character
set. You can then use the + and – buttons to select the
desired character. And then, pressing the SET button
adds the selected character to the end of the current
password.
–: Deletes the last character in the current password.
SET: Enters the character or edited password.
4 Set the encrypted transmission function on the
transmitter to PASSWORD.
5 On the transmitter, set the same password that was set
on the receiver.
For details on transmitter operations, refer to the
operating instructions supplied with the transmitter.
It is recommended that you change the password
periodically.
