upon power-up when the lamp has reached the specified lamp limit and should be
replaced. Delete the checkmark to prevent display of this message—instead, when
your lamp expires, only the status display messages on the back of the projector will
provide the visual warning to replace the lamp.
NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2)
When a lamp warning message appears, press

replacing it. This will trigger a lamp message on-screen (if enabled).
NOTES: 1) If you change modes over the life of a lamp, the lamp limit you originally
expected may no longer be possible. 2) Turning the lamp on and off repeatedly
reduces lamp life significantly, as do other factors, such as hot re-striking. 3) It is
recommended that Lamp Limit not exceed the warranted lamp life, otherwise a lamp
could become dangerously fragile with overuse.

the light output (see Figure 3.26). You can choose to run the
lamp as bright as possible (i.e., always using maximum
power—this is the default). Alternatively, power the lamp
with a specific wattage appropriate for the installed lamp, or
set a desired intensity (brightness) to maintain. Although there are exceptions,
generally higher light output or higher power settings can shorten lamp life.
Use the lamp mode that best suits your brightness needs. For example, in a tiled
application you may want to precisely match brightness levels between adjacent
images—judge by eye and set each individual
