PowerLite 83+ Multimedia Projector

Sleep mode conserves electricity by automatically turning off the lamp after the projector has not been used for 30 minutes (you can set the sleep mode from 1 to 30 minutes.) In sleep mode, the projector’s power indicator is steady orange and only a minimum amount of the projector’s circuitry remains on. This conserves electricity, cools the projector, and extends the life of the lamp. You can turn sleep mode on or off in the Settings menu.
