By placing the activity buttons on every page, this design takes advantage of systems that may not include an RF base. If you choose an activity and the IR command didn't get to the device, you can simply choose the activity a second time without having to back to the home page and select the button again. This design is very customer friendly and was intentionally designed to have less buttons on the source control pages by using the only the most commonly used commands for each device. There are additional sized buttons to copy and paste in case you need to include more functions or change a device page.
