A:Answer The LG CineBeam LED Projector with Built-In Battery, Bluetooth Sound Out and Screen Share, Model # PH550 does have a time setting function that you can use to select a Time Off, Time On, Sleep Timer, Auto Off, or Auto Standby. Ensure good ventilation around the projector. The distance between the projector and the wall should be at least 30 cm. Excessive heat in an improperly ventilated area may cause the unit to shut down after some hours of use due to internal overheating...^IFV
