Using the rFR2 socket on the back of your sky unit gives you house wide channel changing abilities.
By default the voltage of 9volts is off that runs the magic eyes,the option off on off is buried in the menus
The latest sky rrecievers need a seperate unit to allow the use of the magic eyes so if you suddenly lost your magic eye capability then call us sky wont sort the problem for you when they do fit the newer box unless you ask them to
