Installation GS Series User Manual21 020-001044-02 Rev. 1 (07-2016) If you do not press again, the warning me ssage disappears after three seconds and the projector remains on. Adjusting the projector position When you select a position for the projector, consider the size and shape of your screen, the location of your power outlets, and the distan ce between the projector and the rest of your equipment. Follow these general guidelines: • Position the projector on a flat surface at a right angle to the screen. The projector (with the standard lens) must be at least 4.27 feet (1.3 m) from the projection screen. • Position the projector to the required distance from the screen. The distance from the lens of the projector to the screen, the zoom setting, an d the video format determine the size of the projected image. • Determine the lens throw ratio: • Lens 0.75~0.95 (WU/HD) • Lens 0.95~1.22 (WU/HD) • Lens 1.22~1.52 (WU/HD) • Lens 1.52~2.9 (WU/HD) • Lens 2.9~5.5 (WU/HD) • 360 degree free orientation operation
Installation GS Series User Manual22 020-001044-02 Rev. 1 (07-2016) Calculating the lens offset Adjust the offset to align the imag e on the screen with full image size. • The vertical image offset (shift) ranges fo r the projector are +/-50% (WUXGA) and +/-60% (HD). • The horizontal image offset (shift) range for the projector is +/-30% (HD/WUXGA). • The method for calculating lens offset complies with industry standards. For example for vertical lens offset: • At 0% offset (or on axis), the center of the image is on the lens center, so half of the image appears above and half appears below the lens center. • At +50% offset, all of the image appears above the lens center. • The percentage (%) offset is calculated as th e ratio of the number of pixels shifted up or down to full image size. For example for WUXGA: • Shifting up 600 pixels gives an offset of 600/1200 * 100% = 50% • Shifting down 600 pixels gives an offset of -600/1200 * 100% = -50% • Shifting up 720 pixels gives an offset of 720/1200 * 100% = 60% • Shifting up 240 pixels gives an offset of 240/1200 * 100% = 20% WUXGA projectors The following show vertical image offsets for the WUXGA projectors: • Vertical image offset: 0% Lens center0%

Installation GS Series User Manual25 020-001044-02 Rev. 1 (07-2016) • Horizontal image offset: +/-30% Removing and installing the lens When handling the projector after lens installation, make sure the front lens cap is placed on the lens to protect the lens surface from potential damage. When carrying or moving the projector, do not handle by the lens. This may damage the lens, the chassis, or other mechanical parts within the projector. 1. Center the lens. Ensure the lens is at or near its center position. Attempting to remove the lens with a large offset may cause damage to the lens assembly. Center the lens while the projector is switched on by pressing the Lens Horizontal or Lens Vertical button and then pressing Enter. 2. Turn off the projector. 3. Allow the projector to cool down into standby mode before replacing the lens. 4. After the projector has cooled down and prior to replacing the lens, remove the power cord. Lens center -30%100% +30%

Remove the lens through the front of the projector. 7. To install the new lens, fully insert the lens assembly straight into the lens mount without turning. 8. To lock the lens in place, rotate the lens clockwise .A B A B A B A B
Installation GS Series User Manual27 020-001044-02 Rev. 1 (07-2016) Installing the ceiling mount Mount the projector with a Christie-approved mount (such as the Christie One Mount Plus, P/N: 140-117100-XX), using the four mounting poin ts on the underside of the projector. 1. Refer to the installation instructions and safety guidelines provided in the mount kit (such as the Christie One Mount Plus, P/N: 140-117100-XX). Installing the projector in the rigging frame Install the projector in a Christie-approved rigg ing frame (such as the Christie QwikRig Rigging Frame, P/N: 140-128102-XX), using the four mount ing points on the underside of the projector. 1. Refer to the installation instructions and safety guidelines provided in the rigging frame kit (such as the Christie QwikRig Rigging Frame, P/N: 140-128102-XX). Warning! Failure to comply with the followin g could result in death or serious injury. • When not mounted properly, the projector may fall. • The warranty on this projecto r does not cover damage caused by the use of a non-recommended ceiling mount kit or installation of the ceiling mount kit in an improper location.

GS Series User Manual28 020-001044-02 Rev. 1 (07-2016) Operation The projector has multilingual on-screen display (OSD) menus so you can make image adjustments and change a variety of settings. Most of the projector controls are accessed from wi thin the projector menu system. Several groups of related functions are selectable from the Main Menu as shown below. • To display the Main Menu, on the IR remote keypad or on the built-in keypad on the rear of the projector, press MENU. • To navigate within the menu and adjust a setting up or down, use the arrow keys. • To select a highlighted menu item or use it to change or accept a value, press ENTER. You can then select the next item that you want to adjust in the menu. • To return to the previous menu or exit menus if at top level, press EXIT. Main Menu 1. Size & Position 2. Image Settings 3.

Menu itemDescriptionOptions Size Presets Displays an image with the detected size, or resizes the image by maximizing either the height, width, both, or resizes to the maximum size possible while keeping the original aspect ratio. • Auto—Displays with the detected size. • Native—Displays in its native resolution. • 4:3—Retains 4:3 aspect ratio. • Letterbox—Make the active content enlarge to the full screen. • Full Size—Fills the screen (regardless of the source). • Full Width—Fills display width and keep aspect ratio. • Full Height—Fills display height and keep aspect ratio. • Custom—Stretches the display horizontally or vertically without cutting the image display. • 3D Mode—Displays 3D content. If 3D Mode is selected, all other Size Presets items are grayed out. Overscan Removes noise around the image. • Overscan Zoom enlarges image 6% from the original size. • Overscan Crop cuts 6% of the active pixels in four edges of original image. Size & Position 1.

Operation GS Series User Manual30 020-001044-02 Rev. 1 (07-2016) Pixel Track Ensures that the image quality is consistent across the screen, the aspect ratio is maintained, and the pixel phase can be optimized. Steady flicke ring or several soft vertical stripes or bands across the entire image indicates poor pixel tracking. (Analog RGB signals only) — Pixel Phase Adjusts the pixel phase when the image shows shimmer or noise after pixel tracking is optimized. Pixel phase ca n adjust the phase of the pixel-sampling clock relative to the incoming signal. (Analog RGB signals only) — Horz Position Moves the image right or left within the area of available pixels. — Vert Position Moves the image up or down within the area of available pixels. — Digital Horz Zoom Changes the size of projectors display area horizontally. If the display area has been resized by this setting, it can be moved by changing the Digital Horz Shift and Digital Vert Shift settings. — Digital Vert Zoom Changes the size of projectors display area vertically. If the display area has been resized by this setting, it can be moved by changing the Digital Horz Shift and Digital Vert Shift settings. — Digital Horz Shift Moves the display area horizontally if its size has been changed by the Digital Zoom setting. — Digital Vert Shift Moves the display area vertically if its size has been changed by the Digital Zoom setting. — Geometry Correction Provides two ways for warping control. • PC Mode off—User can do simple horizontal and vertical keystone, pincushion, and 4- corner control by using the on-screen display. • PC Mode on—User can do arbitrary warping or blending control by using PC APP provided separately. Auto Image Forces the projector to reacquire and lock to the input signal. This is useful when signal quality is marginal. • Normal mode—Supports all of the 4:3 input sources. • Wide mode—Supports all of the 16:9 input source and most of the 4:3 input source. For the 4:3 input sources not recognized by Wide mode (for example, 1400 x 1050), perform Auto Image using Normal mode. Menu itemDescriptionOptions
