The product won't go into sleep mode. What should I do?
Make sure Sleep Mode is turned on in the 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.
Note: To locate the settings, press the Menu button on the remote control and select Extended > Operation.
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.
Note: If the projector is being controlled by ESC/VP21 (ASCII) commands over a RS-232C or LAN connection and the RS-232C or LAN port is queried, the projector may not enter sleep mode.Related references
