Whenever you install a new lamp in the
projector, access the Lamp menu to record
the lamp serial number in the projector’s
memory. You can also choose a lamp mode
for regulating power and light output,
change optical aperture size, and access
other read-only information pertaining to
past and present lamps.
LAMP HOURS
shows the number of hours
logged on the current lamp. Whenever you
record a new lamp serial number this value
automatically resets to “0”, where it begins to log time for the new lamp.
NOTE: Read-only. This information also appears in the Status menu.
LAMP S/N
is the serial number recorded for the current lamp. When you install a new
lamp and enter its serial number, the number will appear here. NOTE: Read-only.
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,
