HOW LONG CAN I MAINTAIN BRIGHTNESS? The SC-1 can maintain your “Intensity”
setting until the required power reaches the maximum rating for the lamp. The lower the
setting, the longer it will take to reach this threshold and the longer you can maintain the
desired brightness. Keep in mind that once the lamp power reaches its maximum wattage
(see “Power,” above), this tracking is no longer possible. At this point, the lamp will
gradually begin to dim as usual, even though your original “Intensity” value will still appear
in the menu. To resume accurate tracking, reduce the intensity setting so that the resulting
“Power” value is less than its maximum—the lower the intensity, the longer it can be
maintained.

For example, a 2000-Watt lamp can be driven at no more than 2000 Watts. To produce
desired brightness at the screen, a new lamp would likely need less than this maximum
rating — perhaps 1700 Watts (example only). Over time, however, the lamp requires more
and more current in order to generate the desired light, until eventually the lamp wattage
reaches its 2000-Watt maximum and the lamp power automatically levels off. At this
point, the tracking function terminates (that is, the power level stabilizes) and the lamp
begins to dim normally. Either reduce your “Intensity” setting or replace the lamp.

Do not lower the “Intensity” so much that the corresponding “Power” value reaches its
minimum — the intensity setting will be inaccurate and cannot be maintained.

Lamp History (read-only): Lamp History shows the lamps most recently installed and
recorded in the projector. The Lamp History automatically updates whenever you record a
new lamp serial number; the new lamp is added to the end of the list.

LampLOC: Select LampLOC from the Lamp menu to adjust the position of the lamp
relative to the remainder of the illumination system, to maximize light output. For
instructions on using LampLOC, refer to Maximizing Light Output on page 45.

1. Lamps become more stable over time, thus a specific intensity is
more easily maintained as the lamp ages.
2. Intensity can be set only if the lamp is in “Intensity” mode
3. Intensity cannot exceed the output of Max Brightness mode.
