CONTROL S allows you to control your system and other Sony
equipment with one remote control. In addition to allowing you to
control multiple devices with one remote control, the CONTROL S
feature allows you to always point your remote control at your TV,
instead of having to point it at the other equipment, which might be
hidden or out of direct line of sight.
Use CONTROL S IN to send signals to the TV.
Use CONTROL S OUT to send signals to connected equipment.
