Harmony Hub and IR mini blaster

Whether you use the Harmony App or your Harmony Smart Control remote, the hub stores your setup information
and communicates between your Harmony Smart Control system and your entertainment center devices. The hub
communicates with other devices by Wi-Fi, IR (infrared), and Bluetooth signals, depending on the device.
An IR mini blaster extends the range of the Harmony Hub allowing you to control devices that are on other shelves
or outside of your cabinet, such as a television.

How your Harmony Smart Control works

Devices

Devices are the components of your entertainment system. Examples of devices are:

TV set

Cable or satellite set top box

Audio Visual (AV) receiver

DVD player

Game console
Gather the manufacturer and model number information for each of your devices and record it on the next page of
this user guide. Also write down how devices are connected to one another and the input they must be on. For
example, to watch a movie you might have your television set to input (or source) "HDMI 1" and your AV Receiver
set to input "DVD". Having this information collected ahead of time will make setup much easier.
