12. General - Should I leave my ZapperBox on or off when I'm not watching TV?
When you press the red power button on the remote control, the ZapperBox does not really turn off. It goes into standby (red light). During this time the HDMI output is turned off but all other internal functions keep working. In standby mode, a single-tuner box does channel scans to update guide data. A dual-tuner box is continuously using the second tuner to do channel scans whether it is on or in standby. Therefore, it is more important to put a single tuner box in standby and not so much a dual-tuner box. Putting a box in standby does not save any power.
