The SET-TOP BOX is the link between the gateway and your television that receives your TV signal from the gateway. During normal operation of the SET-TOP BOX, the green power light will remain lit. If this light isn't on, the unit is off or needs to be reset due to a power failure or interruption. To reset it, simply press and hold the power button for five seconds. The Set-Top Box will return to the active mode.
The green light labeled "Link" should also be lit during operation. The red recording light indicates a recording is in progress. If you subscribe to High Definition programming, the blue light labeled "HD" will be lit when you are receiving High Definition programming.
