The number buttons along the top of the control frame appear for any source that uses a keypad on an infrared (IR) remote control. Although these buttons are used primarily for entering channel numbers for a set-top box, you can use them to select chapter numbers for a DVD player or track numbers for a CD player.
When you enter a number, it appears in a queue on the screen. The number of digits the queue can hold is set at the factory to a maximum of 3 digits.
