The box will come out of standby mode and turn on in order to record a pre-scheduled recording. Note that after the recording is done, the box will remain ON and not go back to sleep mode.
I'm trying to understand, why not have the box go back to standby after it's done recording? If the box was in standby originally, it turns on to record, wouldn't it make sense to have the box go back to standby after it's done recording? What's the benefit of having it kept on after recording is finished?
