STEP 6 - Define the Lamp Type
At the TPC, go to the Advanced: Lamp menu (password required). Enter the size of the lamp currently
installed in the projector (default is 2.0 kW).
STEP 7 - Ignite the Lamp
At the main menu of the TPC, press the LAMP button

Maximizing Light Output

Upon powering up the projector with a newly-installed/replaced lamp, activate LampLOC
adjusts the lamp position to help ensure optimized operation as well as peak brightness at the screen. You do
not need an image displayed yet. Once you have done this LampLOC
centered and distanced correctly from the remainder of the illumination system.
At the TPC, automatically optimize lamp position by pressing the Do Auto button in the Advanced: Lamp
menu. Watch the gauge on this menu. After 2-3 minutes, the best lamp position will be established (using an
internal light sensor) and the Do Auto button will no longer be disabled. At this point, light output is
optimized.
NOTE: Lamp must be on and douser (shutter) open during LampLOC™ adjustment. However, the projector
does not need to be displaying an image.

2.6.1 Calibrating Screen Brightness (fL)

In order for the TPC to display screen brightness in footlamberts (fL), you must measure screen brightness at
both extremes of lamp power (minimum and maximum) for a given lamp type, and record these two readings
in the TPC Admin: Lamp menu available to installers. These measurements establish a range (stored in
memory) from which the TPC can interpolate all other lamp power settings, converting them to approximate
footlamberts for display in the menus. Repeat the calibration if you ever switch to a different lamp type/size.
NOTE: For more information about menus and footlamberts, refer to
