This TV Controller is an infrared (IR) device that performs some of the functions of your TV and/or cable/satellite remote. The Power button can be set to control the TV, your cable/satellite box, or both. I set it for just TV. The Channel buttons can affect just your TV (if there is no cable/satellite hookup), or the cable/satellite box. You will need to set up this remote, using the manufacturer's instruction manual and Code list.
If you need more detailed BIG Button or switch access to your TV (Guide, DVR, Volume, etc.), please let me know! But remember, each function will require a button/switch input.
