The product won't go into sleep mode. What should I do?
Make sure Sleep Mode is turned on in the ECO menu and adjust the Sleep Mode Timer setting, if necessary. The Sleep Mode Timer setting designates the amount of idle time before the projector enters sleep mode.
The projector enters sleep mode only if it does not receive a signal for the period of time specified in the Sleep Mode Timer setting. If a computer is connected and turned on, a signal is present and the projector will not go into sleep mode.Related references
