System buttons (or “Circle of Power” buttons)—
The buttons surrounding the red Control4 button (Radio, 
Music, TV, Videos, Comfort [A], Lights [B], House [C], and 
Info [D]) are system buttons that respond differently 
depending on when they are pressed and if and how they 
have been programmed, as described in the remainder of 
this section:
Radio
When the remote control is in a Navigator mode (when 
either On-Screen Navigator or LCD Navigator are active), 
the RADIO Button acts as a shortcut into the radio 
submenu in the appropriate navigator.
When devices in the room are off or the remote control is 
in Device-Control mode (when no Navigator screen is 
active), the RADIO button functions as a Quick Access 
button: Press it to start playing the radio and to be able to 
control the radio source with the device-control buttons.
Initial Press of RADIO button: 
• Turns on the last used radio source, tunes to the last 
used station on that source.
• The remote enters device-control mode for the current 
radio source. The LCD shows current room and current 
radio source.
Subsequent Presses of RADIO button prior to LCD 
time-out:
• Additional presses toggle through the radio sources 
listed in the LCD and turns them on. When the last radio 
source is displayed, the next press loops back to the first 
available source.
