You can see the 3 components which I have input on the LCD screen. The 676 allows up to 15 devices, which should be more than enough for even the most seasoned audio or videophile.
"OFF" and "HELP"
You can turn off all your components with the Off button, and Help is pressed if you experience problems with your activity buttons. Simple questions will be asked on the remote itself, so you don't have to go to the Harmony website unless necessary.
There are 4 Activity Buttons across the top of the LCD screen, enabling several transmissions of functions with just one button press.
Device Select Buttons (3 left / 3 right)
Components can be directly chosen by pressing the arrow buttons on the left or right of the device on the display.
"DEVICE", "MEDIA", and "NEXT"
The Device button allows you to use a specific component directly. The Media button enables you to view television shows, movies, and music from the remote itself. This is a free 2-Month trial. Next is for selecting the next "page" on the remote. I noticed there was no Prev on the remote for scrolling to previous device functions (although there is a Prev located on the lower part for a completely different action), which confused me a little, because scrolling forward when viewing your devices' functions, and not having a Previous selection, is a little annoying.
Record, Stop, Play, etc.
The 8 buttons below are your basic buttons used for a variety recording devices and players.
Sound, Exit, Menu, Info, etc.
These buttons located around the OK button are for specific features within your components themselves, such as your television's sound menu, or your receiver's sound menu. These buttons are very handy and are convenient when you don't want to scroll through your component's entire menu to get to a specific area (such as sound or picture adjustments).
A / B, Page + / -
This area can be used for customizing which speakers are used for particular audio needs. For example, you may want the back speakers (B) to only operate when you have movies playing, and you may want the front speakers (A) to only operate when you have music playing. These two buttons can also be used as another volume control or channel select control as well. It's all up to you on how you want the configuration.
Volume, Channel, Mute, Prev, Glow
These buttons are pretty much self-explanatory. The Prev button can be used for the previous television channel visited.
0 - 9, +, and E
These buttons are basic as well, and would be used in conjunction with any operation requiring number inputs.
