Great bit of kit. I've got one and it works a treat (in a 5 bed house)
The One For All remote control blaster (SV1100) converts the Infra-Red (IR) signals from your remote control into Radio-Frequency (RF) allowing you to control your devices through doors, windows, floors and walls.
Simply put the special transmitting battery supplied into your remote control and put the receiver unit in the room with the source ie your SKY/DVD/Cable or freevew box and you can control the device from anywhere in the house!
The battery must be charged up initially by placing it in a compartment in the receiver overnight, if the battery runs out, you just put it back in to charge up!
