Section 3: Operation
The Lamp Operation modes are:
• Lamp 1 single lamp use or Lamp 2 single lamp use modes will only use the lamp specified. If the selected
lamp will not strike, then the projector will not turn on. If the "Single Lamp Switch on fail" option is enabled,
the projector will always attempt to turn on the selected lamp first, but if that lamp fails all attempts to strike,
it will cause a switch to the other lamp. This option is not enabled for DLV models, which are restricted to
operate in Dual Lamp Use mode only.
• Dual Lamp Use mode will use both lamps together. After 3 failed attempts to stay in Dual Lamp Use mode,
the projector will switch to Single Lamp operation; however, the user-selected mode remains as Dual Lamp
Mode.
• Auto-Select a Single Lamp mode will choose the best lamp for single lamp operation. The lamp selection is
based on:
• The lamp that will be the fastest to turn on (a lamp can be chosen if it is currently on, or if it has been off
for at least the minimum hot re-strike period)
• The lamp that has been least used (determined by the lamp voltage, which increases as the lamp ages)
• The lamp with the fewest hours (this attempts to balance the lifetime of the two lamps)
In Auto-Select Single Lamp mode, a failure of a lamp to strike will cause a switch to the other lamp. This
option is not enabled for DLV models, which are restricted to operate in Dual Lamp Use mode only.
Single Lamp mode, available for DLV models only.
LAMP MODE
Determines how the lamp's power and intensity are controlled. If Maximum Brightness the lamp burns as
brightly as possible. Select Constant Intensity mode to maintain a specific brightness level over time. As the
lamp ages, the projector will increase power as needed, to closely maintain the required output from the lamp.
Select Constant Power to specify the power level supplied to the lamp. Both Constant Intensity and
Constant Power modes extend lamp life.

operate correctly if the LiteLoc calibration has not been performed.
POWER
Set the lamp's power in Watts. The Power control represents the amount of power sent to the lamp(s). 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
Adjust the lamp intensity to the required % of full. This value is used as a target value by the LiteLOC
system to maintain constant intensity.
