Zusammenfassung:	A sleep timer function for consumer electronics equipment automatically turns off the equipment after a predetermined time interval. During the final two minutes of the sleep time interval, the sleep timer circuitry (113, 132, 134) gradually decreases the volume or provides a visual indication that automatic turn off is imminent. The reception of any modulated infrared (IR) signal, transmitted from any source (128), during the timer period is interpreted by the sleep timer function controller as an indication that the user is still awake. In response, the controller resets the count of the sleep timer (113) to the maximum period, thus deferring the automatic turn off of the equipment.
