As you can tell from the video on the previous page the Beacon is a very small device. You can see what I mean from the photo below of it sitting next to an iPhone 4.
On the top of the device is actually where you will find both the Bluetooth receiver and IR transceiver. This top part also functions as a button to activate the Bluetooth search function so you can pair it with your iOS device.
If you flip the Beacon over there are 2 small logos that tell you how to position it. You are going to want to place the Beacon in front of your TV with the remote side pointing out. The Beacon takes 4 AA batteries.
