At anytime during operation, you can check the status of a lamp by checking the
lamp status in individual lamp submenus – More, Lamp 1 or More, Lamp 2.
Here, you will see a status message for the lamp that specifies a specific failure
that will require further investigation and may or may not be directly related to
the lamp. If, through the investigation, you have ruled out the cause being an
aged lamp or another component in the projector, it may indicate that your lamp
has prematurely burned out or failed for some other reason (check status LEDs
and/or error codes through RS-232, if possible). Burned out lamps or lamps that
have failed due to some characteristic flaw should be replaced as soon as
possible.
In general, monitor the performance of your projector and replace lamps as
needed.

approximately 5 minutes after the internal cooling fans have turned off. Once
fans have stopped turn the main power switch OFF before continuing with

still on and without disrupting the current presentation (hot-swap), then
ensure the lamp to be removed is cool before proceeding with removal - Step
2.
Wait at least 5 minutes after powering down or switching
lamp operation modes to allow the lamp to cool
