Quote below, from section 3.7.1.3
We would like this to happen if no power toggle option. Device losses AC power, then restored and remembers its state and CH.
For an installed speaker. User does not have access to power toggle button or ch selection Installer sets the CH and leaves it alone.
"If the power toggle button is not enabled in the device configuration, the CC85xx will automatically enter the ACTIVE power state at power up, and can only be shut down by disabling the power supply. In this case, output volume settings and dynamic channel selection will not be stored to non-volatile memory, and the configured default values will be used at every power-up. "
