Using the Encrypted Transmission Function
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:
Secure key mode
: A secure key that is automatically
generated by the transmitter is used by both the transmitter
and receiver in this one-to-one encrypted transmission
method.
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.
• When using an encryption key method, pair 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 wireless remote
control function
(see page 30) , 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 transmitter
Set SECURE KEY on the transmitter that will transfer
the encryption key.

then press the dial.
2
Rotate the jog dial to select SECURE KEY, and
then press the dial.
3
Exchanging the encryption key
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.
When the RF REMOTE function (see page 30) is off,
encryption key exchange cannot be carried out.
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
In the RECEIVER menu, rotate the jog dial to move
the cursor to ENCRYPTION indication, and then

that you want to enter. And then, press the dial to add the
selected character to the end of the current password.
To delete the last character in the current password
Rotate the jog dial to select BS, and then press the dial.
Note that the adding or deleting a character in the
middle of the password cannot be done.
To cancel entering the password
Rotate the jog dial to select CANCEL, and then press
