Our FIOS set top box (Motorola 6200) has begun to go into standby mode on its own. This usually happens in the middle of the night while I'm recording a program. The recording shows a pop-up message that indicates the the stb will go into standby mode unless an option is clicked. Of course, it goes into standby mode because no one is there to click.
This also occurred during the day while I was recording a program. The TV was on but I was in another room when it went into standby.
How can I prevent the stb box from going into standby?
