Initial State From Charger is set to Active, the transmitter will only
pass audio when you push the mute button. Make sure to coordinate
settings for Mute Button Behavior and Initial State From Charger.
Audio Signal Encryption
When encryption is enabled, the receiver generates a unique encryption
key which is shared with the transmitter during an IR sync. Transmitters
and receivers that share an encryption key form a protected audio path,
preventing unauthorized access from other receivers.
Enable encryption using Wireless Workbench or the receiver front panel.
For more details, see the user guide for your receiver.
