ADVANCED / LAMP MENU OPTIONS
LiteLOC Maintains a chosen light level at the screen over time—the lamp ballast will
gradually increase power to the lamp as necessary, until it reaches the
maximum level possible for the installed lamp. To disable LiteLOC temporarily or
permanently, clear the LiteLOC "Enable" checkbox or adjust Lamp Power
directly.
Set (Brightness) With the desired light output measured at the screen (typically 14 fL), press the
Set Brightness button to automatically enable LiteLOC. The current brightness
level will be maintained as long as possible. NOTE: Arbitrary units-of-measure
appear here, not footlamberts or lumens.
Lamp Power Indicates what percentage of power (appropriate for the installed lamp) to
supply to the lamp, automatically overriding any LiteLOC setting that may be in
effect. This causes the bar graph to rise or fall, but the LiteLOC line and "Set"
values will not change unless "Set" is pressed (defining a new LiteLOC setting).
Lamp Power range = 75%-110%, representing the percentage of the lamp's
power rating. Factory default = 75% power.
LampLOC LampLOC buttons activate motors that reposition the bulb in the projector for
optimized light output. Use the Do Auto button (recommended) or the individual
buttons. Notes: 1) Lamp must be ON to begin. If it is turned off during a re-
positioning, the bulb will return to its former position. 2) Douser opens and
remains non-functional during a LampLOC adjustment.
Lamp (read-only) Indicates the current lamp age, amps (current), volts (voltage) and watts (lamp
power). Read-only "FYI".
New Lamp Activates the lamp history window and text editing box for recording a new
lamp's serial number, which resets the lamp timer. This button can also be
accessed with an "Operator" login at the TPC.
Light Level Indicates current light output (shown as solid vertical bar) and LiteLOC level set
(Meter Reading) (single horizontal line). Consider the value at the top of the meter as arbitrary—
i.e., not representing actual lumens or fL.
