Temporarily Unlock a Mature Channel
When the global "Mature Lock" is enabled, a mature channel can be temporarily
unlocked. All mature channels are temporarily unlocked (but still hidden when
channel browsing) until the SXM source is changed, Accy (Key) is cycled or the
"Power Button" on front panel of radio turns the Radio off.
This mode is useful for listening to mature/adult content on a temporary basis,
allowing you to listen on a locked channel without having to disable the global
"Mature Lock. "
