Section 3: Operation
POWER
Sets the lamp power in Watts. The Power control represents the amount of power sent to the lamp. Power
increases when operating in Intensity mode, until it reaches its maximum. The value remains stable when in
Max Brightness or Power mode. If using Power mode, setting a lower power level reduces brightness and
extends lamp life.
INTENSITY
Adjusts the lamp intensity to the required % of full. This value is used as a target value by the LiteLOC™
system to maintain constant intensity.
OPTICAL APERTURE
Controls the diameter of the light beam passing through the system. With a fully open aperture (slide bar
default of "0"), the maximum amount of light passes through for maximum image brightness. To reduce the
aperture diameter and maximize contrast ratio, increase the slide bar setting.
aperture depends on the lens in use.
WARN WHEN LAMP REACHES (HOURS)
Allows the maximum number of hours (threshold) to be set for lamp usage. When the threshold (set number of
hours) is reached a warning message displays on the status system, indicating that the lamp should be changed.
This setting is user-defined only, has no bearing on lamp warranty, and is not tied to actual lamp life in any
way. The default setting is 0, which means that the feature is off, and no warning will be generated.
LAMP s/n
Records the lamp serial number. This will apply the serial number to the current lamp statistics file. It will not
perform the archiving as done by the CHANGE LAMP function.
CHANGE LAMP - Submenu
Initiates the lamp change process and allows the serial number of the new lamp to be entered.
Lamp serial numbers are used for keeping statistics on each lamp. Entering of serial numbers is optional, but is
recommended.
When using this function, the statistics from the previous lamp are archived, and statistics for the new lamp are
tracked. If this function is not used, statistics are accumulated (combined) for both the new and old lamps.
LAMP HISTORY
Lists the serial number and the number of hours logged for the lamp (current and previously) installed in the
projector. The current lamp appears at the bottom of the list. This entry is added automatically when you record
a new serial number during the lamp change process. See
3-52
