The product won't go into sleep mode. What should I do?

• Make sure Sleep Mode is turned on in the Extended menu and that the Sleep Mode Timer setting is set to the desired length of time before the projector turns off automatically.
  

  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 connection and the RS-232C port is queried, the projector may not enter sleep mode.
