Section 3: Operation
Projector Variables: Using a Wide Converter Lens
The optional Wide Converter Lens acts similar to a zoom lens. It magnifies a “flat” image format of 1.85:1 to a
“scope” image of 2.39:1, while maintaining the full resolution of the source material.

Theatre Variables: Masking
In order to present either type of feature on a single screen, a theatre typically uses masking to conceal any unused edges(s) of the screen. These movable flat black panels, or black curtains, are most commonly installed along the top edge of the screen changing the height of the screen but not its width.
Top Masking
• Add top masking for “scope”
• Raise top masking for “flat”
Figure 3-54 Top Masking for Scope
Side Masking
Alternatively, curtains (masks) may be installed at each side of the screen in order to change the width of the screen but not its height.
• Bring in masking from sides for “flat”
• Open masks for “scope”
In some cases, a theatre has both side and top/bottom masking installed.
This arrangement is the most flexible of all.

3.10 Non-Cinema Operation
This subsection explains how to display alternative content originating from standard definition or high definition non-cinema sources such as a PC or other graphics devices.
Connect your non-cinema DVI source to the DVI-1 and DVI-2 ports. Each DVI port accepts and will autodetect the progressive scan, digital RGB sources (
) displaying them in their original incoming format. Currently, DVI signals cannot be scaled to a different size and/or aspect ratio. NOTE : Each DVI port is a single-link port for a single-link cable/connector only. Using this pair of ports as a higher-bandwidth duallink or twin-link pair requires additional hardware and is not currently supported.

3.10.1 Selecting a Source
For any display, the projector interprets incoming signal data according to one of 64 user-selectable display files defined at the time of installation (or with each subsequent release of a new digital cinema feature) and stored in projector memory. Each file is essentially a collection of processing/display settings optimized for a particular cinema feature or non-cinema content, which enables consistent presentations with minimum further adjustment. Each file is represented by an assigned “channel button” selectable over several pages of the Main menu from the web user interface. Depending on your installation, you may have 0-64 different non-cinema sources defined for use. For more information, refer to
.
SELECT A NON-CINEMA SOURCE : With a non-cinema source connected to the projector, select the desired noncinema source display button from the Main menu or by scrolling through a CHANNEL LIST on the CDP. Once selected, the projected display changes according to the corresponding file settings.
RETURN TO A CINEMA SOURCE: Select one of the cinema display buttons pre-configured for a cinema source input at port 292A or 292B from either the Main menu or from the CHANNEL LIST —the projector now ignores the DVI ports and responds to the cinema source selected.

4.1
Safety Warnings and Guidelines
4.1.1 Labels and Marking
Observe and follow any warnings and instructions marked on the projector.
The exclamation point within the equilateral triangle indicates related operating/maintenance instructions in the documentation accompanying the projector.
The lightning flash and arrowhead symbol within the equilateral triangle indicates non-insulated
“dangerous voltage” within the projector's enclosure that may be of sufficient magnitude to constitute a risk of electric shock.
4.1.2 General Precautions
Be aware of the following general precautions in all CP2000-ZX installations:
Warnings! 1) Never look directly into the projector lens or at the lamp. The extremely high brightness can cause permanent eye damage. 2) For protection from ultraviolet radiation, keep all projector housings intact during operation. Protective clothing and safety goggles are recommended.
NOTES: 1) The American Conference of Governmental Industrial Hygienists (ACGIH) recommends occupational UV exposure for an 8-hour day to be less than 0.1 microwatts per square centimeters of effective
UV radiation. An evaluation of your workplace is advised to assure employees are not exposed to cumulative radiation levels exceeding the government guidelines for your area. 2) Be aware that some medications are known to increase one’s sensitivity to UV radiation.
Warnings!
1) FIRE HAZARD. Keep hands, clothes, and all combustible material away from the concentrated light beam of the lamp. 2) Position all cables where they cannot contact hot surfaces or be pulled or tripped over.
This projector must be operated in an environment that meets the operating range specification in
