4. To change your LiteLOC setting, adjust the Lamp Power as desired and then

press “Set”. The LiteLOC

 function will automatically begin to maintain this

new setting.

WHEN SHOULD I USE LiteLOC? Typically, most theatre installations would use

LiteLOC

 for daily operation, since it need only be set once for each lamp install,

and ensures consistent worry-free brightness at the screen for as long as possible. If

desired, reset LiteLOC

 to a different level at any time, or override with a specific

lamp power setting.

HOW LONG CAN I MAINTAIN BRIGHTNESS? Software can maintain a LiteLOC

setting until the required power exceeds the maximum rating for the lamp (2.0, 3.0,

4.5, or 6.0 kW) by approximately 10%. The lower your LiteLOC

 setting, the longer

it will take to reach this “over-drive” threshold and the longer you can maintain the

desired brightness.

For example, a 6000-

watt lamp (6.0 kW) can

be safely driven at no

more than 6600 watts.

To produce 14 fL at the

screen, a new lamp

would likely need less

than this maximum

rating—perhaps 5120

watts (example only).

Over time, however, the

lamp will require more and more current in order to produce the 14 fL, until

eventually the lamp wattage reaches its 6600 “overdrive” maximum, and the power

to it automatically levels off. At this point, the LiteLOC

 function terminates (i.e.,

the power level stabilizes), the lamp will begin to dim normally with age, and the

light output gauge will begin falling. Either reduce your LiteLOC

 setting or replace

the lamp.

Using “Lamp Power”

To change to a different power level, simply enter a new Lamp Power percentage at

any time. This will override (and temporarily disable) any LiteLOC

 setting that

may be in effect:

1. Set “Lamp Power” to apply a specific percentage of power appropriate for the

installed lamp. LiteLOC will automatically be disabled.

2. Brightness will change accordingly, new values will appear for amps, volts and

watts, and the blue light output bar graph will move above or below the

LiteLOC line, depending on the new setting.
