Using the CONTROL S Feature

CONTROL S allows you to control your projection TV 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 projection TV,
instead of having to point it at the other equipment, which might be hidden
or out of direct line of sight.
