Enter a checkmark for LAMP MESSAGE to enable a warning message that will appear
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 Exit to temporarily cancel the
message. The message will continue to appear upon power-up until you install a new
lamp.
Set LAMP LIMIT to the number of hours you expect to log on the current lamp before
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 reduces lamp life
significantly, as do other factors. 3) It is recommended that Lamp Limit not exceed the
expected lamp life, otherwise a lamp could become dangerously fragile with overuse.
Set which LAMP MODE you want to use in order to control the
light output. You can choose to run the lamp as bright as possible
(i.e., always using maximum power—this is the default upon
power up) or you can power the lamp with a specific wattage
appropriate for the installed lamp or you can set a specific
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 Lamp Power setting as necessary. Or if you want images
to be as bright as possible—choose Max Brightness. Always keep in mind that higher
lamp power settings can shorten lamp life.
Lamp modes are described below:
• Max Brightness: The lamp will always burn as brightly as possible, driven by
100% of the power level rating for the installed lamp (see Section 6, Specifications).
Keep in mind that the "maximum brightness" for any lamp gradually diminishes
with age — images will become dimmer over time. Its current output level appears
in the "Intensity" option (note: not in lumens).
• Intensity: Brightness will remain close to a specified level for as long as possible.
Once you select this option, enter a number representing the intensity level
(brightness) you wish to maintain—the projector will automatically adjust power
as needed to maintain this intensity as closely as possible. Note that the intensity
value is a correlation only and does not represent an actual lumens level. See
"Intensity" on the next page.
• Power: The power supplied to the lamp will remain at your specified wattage
level. Once you select this option, enter the number of watts representing the
power level you wish to maintain. See "Power" on the next page.
