For any new installation, you will likely have to safely lift or hoist the projector

into place. Keep in mind the following guidelines for safety.

8VLQJ#WKH#,QWHJUDO#+DQGOHV

The projector includes integral wrap-around aluminum handles for convenient grasping. While these handles are adequate for brief hand transport, such as lifting or carrying over short distances by 2 or more people, the end handles are not intended to support the entire weight of the projector for extended periods of time. In particular, do not hoist or suspend the projector from these end handles or use them in an installation (see Figure 2-1).

users or installers should always consult their dealer when deciding on screen type. The following guidelines explain the differences between screen types.

)URQW#6FUHHQ#,QVWDOODWLRQV

There are two basic screen types: flat and curved. The choice between a flat screen or a curved screen is dependent on audience viewing angle and screen gain. There is always a trade-off between viewing angle and gain. Viewing angles for both screen types are illustrated in Figure 2-4 and Figure 2-5 (plan views).

Flat screens offer a gain of about 1 with a viewing angle just less than 180°. Incident light reflects equally in all directions so the audience can see the display from various angles. Because of the lower gain, flat screens are more effective when ambient lighting is reduced, although this difference may be negligible given the ultra high brightness output from this projector.

)LJXUH#5081#$XGLHQFH#&RYHUDJH#ZLWK#&XUYHG#6FUHHQ

Curved screens have gains larger than 1 (due in part to the screen material) and viewing angles much less than 180°. Most curved screens have different horizontal and vertical viewing angles. Incident light does not reflect equally in all directions. The reflected light concentrates in a conical volume or "viewing cone". Audiences within the viewing cone see a brighter image than that from an equal area on a flat screen. Audiences outside the viewing cone see a dimmer image.

NOTE: Vista

GRAPHX

10K lenses are designed primarily for use with flat screens. However, the projector depth-of-field range allows the lens to be focused on curved screens as well. Focus remains sharp in the corners, however there may be significant pincushion distortion, primarily at the top of the screen.

5HDU#6FUHHQ#,QVWDOODWLRQV

There are two basic types of rear screens: diffused and optical. A diffused screen has a surface which spreads the light striking it. Purely diffused screens have a gain of less than 1. The main advantage of the diffused screen is its wide viewing angle, similar to that of a flat screen for front screen projection. Optical screens take light from the projector and redirect it to increase the light intensity at the front of the screen. This reduces it in other areas. A viewing cone, similar to that of a curved front screen installation, is created.

8VHU*V#0DQXDO

508

,167$//$7,21#)#6(783

6FUHHQ#6L]H

To summarize, optical screens are better suited for brightly lit rooms where the audience is situated within the viewing cone. Diffused screens are best suited when a wide viewing angle is required but there is low ambient room lighting.

Screen size may be from 6 to 40 feet diagonal, depending on the lens you are

using. For instance, a 1:1 lens produces a 6-30 foot image size, whereas a 4-7:1 zoom lens produces a 10-40 foot image size. Choose a screen size which is appropriate for your lens and application. Keep in mind that if the projector will be used to display text information, the image size must allow the audience to recognize all text clearly. The eye usually sees a letter clearly if eye-to-text distance is less than 150 times the height of the letter. Small text located too far from the eye may be illegible at a distance no matter how sharply and clearly it is displayed.

To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect ratio of the image. The aspect ratio of an image is expressed as the ratio of its width to its height. Standard video from a VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a 10 foot (3m) high screen, the width of the screen must be at least 13.3 feet (4m).

Note: Screen size is often specified as diagonal size. Screens specified by diagonal size have aspect ratios of 4:3. Screens with other aspect ratios are not typically specified by diagonal size.

,GHDO#5RRP#/LJKWLQJ

The high brightness output of Vista

GRAPHX

10K is certainly well suited for

locations where ambient lighting is less than optimum for projection, but there are still many simple things you can do to optimize your installation.

Visiting a movie theater can give you an idea of what makes an ideal projection environment. Walls, floors and furnishings are dark and matte finished. A projection room should not have white reflective ceilings or non-directional lighting such as fluorescent lights. The white ceiling spreads light, making the room appear brighter. Keep lighting and reflections to a minimum.

If it is not possible to eliminate fluorescent lights, consider using incandescent spot lighting or parabolic reflectors ("egg crates") to direct light down to the floor. Light dimmers or rheostats allow further control.

Outside windows are undesirable in any projection room. A small crack between curtains on a sunny day can wash out a projected image. If you do have windows, make sure that window coverings are opaque and overlapping — some window coverings are designed to provide up to 100 percent blockage of outside light. Ideally, the material should have a matte finish.

To minimize the effects caused by unwanted light from door and aisle ways, carefully choose the position of your projector and screen. Figure 2-6 shows an installation where poor screen placement allows too much unwanted light to enter the screen. In Figure 2-7, the screen and the projector are positioned so that unwanted light is minimized.

)LJXUH#50:1#%HWWHU#6FUHHQ#3ODFHPHQW

Even with all lighting removed it is still possible that room reflections within the room can slightly degrade the image. Light from the projection screen should be absorbed by the ceilings, walls and floors so that it will not be reflected back to the screen. Again, keep reflective surfaces to a minimum.

Here are some other considerations and tips which can help you improve your

installation:

• Ventilation is an important factor when preparing a projection room. The

ambient temperature should be kept constant and below 35°C (95°F). Keep the projector away from heating and/or air conditioning vents. Changes in temperature can cause drifts in the projector circuitry which may affect performance.

• Keep the projector away from devices which radiate electromagnetic energy

such as motors and transformers. Common sources of these are slide projectors, speakers, power amplifiers, elevators, etc.

• For rear screen applications, less space is required if a mirror is used to fold

the optical path.

• Choose the right screen size for the application:

,167$//$7,21#)#6(783

◊ As screen size increases, magnification increases which reduces

brightness. Select a screen size which is appropriate for the venue, but not larger than that required.

◊ Installing a large screen in a small room is similar to watching

television close up; too large a screen can overpower a room. A good rule of thumb is to be no closer than 1.5 times the width of the screen.

◊ Larger screens require greater attention to lighting conditions.

• When laying out the projection room, consider positioning the projector and

screen in a manner which will achieve maximum audience coverage and space efficiency. For example, placing the screen along the larger wall in a rectangular room will reduce audience coverage. Figure 2-8 shows two examples of how audience coverage is maximized.

Installation type, screen type, and lighting all affect where the projector is positioned. In addition, both throw distance (the distance between the projector and screen) and vertical position (the height of the projector in relation to the screen) must be determined for every new installation. Both depend on the screen size and projector lens type you are using. Make sure that the room can accommodate the required position of the projector for the chosen screen size.

Throw distance is the distance between the projector's front feet and the screen.

It is measured perpendicular to the lens surface and screen surface. As you move the projector farther from the screen, the image becomes larger.

Throw distance is roughly equal to the horizontal width of the screen multiplied by the type of lens you are using. For example, if you are using a 3.9:1 lens, throw distance should be approximately 3.9

[

the screen width. Once you know your screen size, you can estimate how far away the projector should be, as shown in Table Chapter 2 -1.

,03257$17=

For exact placement in an installation, always refer to the throw distance formula and/or graph for your lens as listed in Appendix E.

NOTES: 1)While throw distance is measured perpendicular to the screen and projector, this measurement is not necessarily parallel to the floor — both projector and screen may be inclined together. 2) It is good practice to simulate the setup with the projector fully warmed-up to determine the precise throw distance required. 3) Always use the throw distance information from Appendix E.

9HUWLFDO#3RVLWLRQ

The vertical position of the projector in relation to the screen also depends on the

size of the screen and the lens type. Correct vertical position ensures that the image will be rectangular in shape rather than keystoned (having non-parallel sides) and that image focus and brightness both remain optimized.

Vertical position is offset—that is, the image can be moved—by using the key. This displays the Lens menu, where both horizontal and vertical offset can be adjusted with slidebars. Note that the range of adjustment depends on the lens type you are using. See Table Chapter 2 -2 for the number of pixels by which you can move an image using a specific lens. Refer to Figure 2-9 to see more clearly how the pixel offset ranges affect the placement of your image in relation to the vertical position of the projector.

NOTES: 1) If you cannot raise or lower the image enough for your installation, or if the image becomes keystoned or exhibits uneven brightness, the projector is probably too high or low in relation to the screen. 2) Recommended offset ranges can be exceeded, however this may affect image quality. 3) Simultaneous

horizontal

offset can limit the range of vertical offset.

The front panel of the projector has two standard input panels to which you may connect a variety of sources. The upper right panel (Input 1) accepts an RGB input from an external RGB source with audio follow-through. The lower left panel (if video decoder module is installed) accepts composite video (Input 3) or S-video (Input 4) and audio from devices such as video tape or disk players. There are also several optional interfaces available for connecting other sources (Input 2). Such an option installs in the upper left panel. See Figure 2-12.

10K supports multiple sync

types: sync-on-green for data, composite, and separate H & V.

NOTE: Depending on the source, you may need a custom adapter cable that has BNC connectors at the projector end and different type of connector at the other (such as a 15-pin "D" connector for computer sources). Contact your dealer.

Connect the sync BNC input(s) first. Then connect the red, green and blue source outputs to the RED, GREEN, and BLUE inputs on the panel. If the source uses sync-on-green, only the red, green, and blue connections are required. If the source provides a composite sync output, connect it to the H/C SYNC input. If the source provides separate horizontal and vertical sync outputs, connect horizontal sync to the H/C SYNC input and connect vertical sync to the V SYNC input. See Figure 2-13.

You may wish to use a computer rather than a keypad for controlling the projector and for performing other special functions. From most computers, connect an RS-232 serial communication cable between the computer and the projector serial port labeled "NETWORK IN" (Figure 2-17). Then set the projector baud rate to match that of the computer. Changing the baud rate is described in 3.7, Adjusting and Checking System Parameters.

NOTE: In rare instances, some computers can provide communications. See

7KH#560755#3RUW

Some computers can provide

RS-422

serial communications (usually through a plug-in adapter or external converter) rather than the RS-232 typically found on most computers. RS-422 communication has differential transmits and receives and is generally better suited for long distances than is RS-232 communication.

If you wish to control the projector with a computer having RS-422 capability, connect the computer to the projector’s RS-422 port instead of the port labeled “NETWORK IN”. Again, use RS-422 only if you are certain that your computer has RS-422 capability (consult your documentation). See Figure 2-18.

Each projector can be assigned a unique 3-digit projector number (for example,

001). These numbers are particularly useful when you are working with multiple linked projectors, enabling you to direct commands to a certain projector rather than broadcast to all projectors. For complete information on how to assign projector numbers, see 3.7, Adjusting and Checking System Parameters.

3URWRFROV

At manufacture every keypad is assigned a default protocol, which is simply a collection of settings that determine how the keypad operates. Once assigned, this protocol remains in effect until it is changed — that is, the keypad will operate as it currently does until you change its protocol.

Protocols are most useful for multiple-projector applications. For example, you might want to change a keypad protocol if you are working with two projectors and two remote keypads in the same room and need to control each projector independently (Figure 2-22). When Keypad A has a different protocol than Keypad B, each keypad communicates only with the projector having a matching protocol. Or, if you have a network of two or more projectors connected together via RS-232 serial ports, you may want only certain projectors to respond to a wired keypad.

NOTE: Matching the protocol on the projector to that of a keypad is done through a setting in the Vista

and Checking System Parameters

GRAPHX

10K Preferences menu. See

3.7, Adjusting

for further information on how to change the

projector's infrared sensor (rear and front) protocol.

A protocol for either type of remote keypad — IR or wired — can be changed through software commands entered on the keypad. A new protocol set through software commands remains in effect until the keypad batteries are removed and replaced (if an IR remote), or until the keypad is unplugged (if a wired remote). A remote can also be changed manually —you can "hard-wire" new jumper settings inside the keypad so that they remain in effect until you change the hardwiring. Note that a hard-wired protocol can be temporarily overridden by the software protocol change, effective until the keypad is unplugged and plugged in again (if a wired remote) or until a battery is removed (if an IR remote).

This keypad is located at the rear of the projector. An LCD window above this

keypad provides feedback regarding current status and activities of the projector. The IR Remote Keypad controls the projector by way of wireless

communications from a battery-powered infrared (IR) transmitter. Use the IR remote keypad the same way you would use a remote keypad supplied with a TV or VCR. When making key presses, point the keypad either toward the screen or toward the front or rear of the projector. One of two sensors on the projector will detect the signals and relay the commands for internal processing.

The wired remote keypad connects to the front 3-pin XLR jack via a 50 ft.

extension cable. It is recommended when:

Press keys one-at-a-time; there are no simultaneous key presses required.

For any key having an “*” (

repeat their “arrow” actions when held down. For

other keys, release and press again to repeat an action.

If you press a key while the projector is busy with another action, such as during a power-up, the key press may not take effect.

When you turn on the projector it begins operating at presentation level, such as an image from the most recently used source signal. The projector temporarily leaves presentation level whenever you use the keypad to work with control settings, display menus, or on-line help. For example, pressing

An input simply describes a physical location for an incoming signal connection. These connections are always either on the projector itself (one of the four inputs at the front of the projector) or on any switcher connected to the projector’s switcher port.

The first digit specifies the switcher (0-9), the second specifies the slot (1-9). Note that the projector is always considered “switcher #0”.

Regardless of which method you use to select a source/input, the image will be displayed according to the following:

If it is the first time you have used the source/input

(or if you used the input but did not adjust anything), the projector will recognize the input signal based on its frequencies and polarities, and will automatically display the image according to default settings for such a signal. It will resize as needed, producing an image as large as possible while maintaining the original aspect ratio.

If you used the source once before and changed a display parameter

such as focus, contrast, etc., then a channel was created and still exists in projector memory (see below). Using an

A channel is a collection of measurements and settings that tailor a display to your specific needs. Since source types and applications vary greatly, you will likely want to adjust and define a wide variety of parameters, such as brightness, contrast, tint, etc., in order to customize and maximize the display coming from that source. For example, the display settings you choose for a VCR source may be very different from those you choose for a high resolution computer source, or one signal may vary from another used earlier through the same input location. Once you have adjusted a display parameter, such as zoom, focus, or pixel tracking, all current settings are collectively stored in the projector's memory as a unique 2-digit channel, such as

Pixel tracking adjusts the frequency of the pixel sampling clock, indicated by the number of pixels per line, so that all pixels generated by a particular source are

23(5$7,21

sampled. Proper pixel tracking ensures that the image is of the correct proportion and not stretched or compressed from left-to-right.

NOTE: By default, the projector samples at the correct frequency for a given source. For best results, it is recommended that this default not be overridden.

Pixel tracking is adjusted most effectively using a good test pattern, such as a smooth gray image made up of a clear pattern of tiny black and white dots, or a similar graphic image. Steady flickering or several soft vertical stripes or bands across the entire image indicates poor pixel tracking. Adjust the slidebar up or down until the stripes broaden to the point where one large stripe fills the image.

Adjust until the image is stable and each dot is clearly defined. Using the numbers on the slidebar as a guide, you will notice that you can actually stabilize the image at more than one point—i.e., you may find that the image appearance at "11" is the same as the image appearance at "38", thus you can select either setting.

- In specialized applications, such as when you are matching adjacent displays with numerous sources, you may find that you need a specific color temperature that lies somewhere between one preset color temperature and another. In this case, select the Interpolated option and use the slidebar to adjust the temperature as desired in increments of 10°K. This new temperature, which is interpolated from the neighboring presets, can be used with any source and appears as shown when it is in effect:

NOTE: The “default” temperature option you begin with automatically changes to “custom” as soon as you begin adjusting— you will not lose the preset. If you make a mistake and want to start over, select “default” again to reset.

The 3 drives and 3 blacklevels for the default temperature you selected are shown in the menu. Note that the blacklevels are likely all set to 30, and drives are 73 or less.

NOTES: 1) Always try to achieve the desired effect by first increasing the drive level for the color judged to be weak. If the drive level for that color is already at 73, then decrease the contrast level for one or more of the other colors. 2) If you want to adjust each color individually, you can connect only one signal cable — red, green or blue — at a time.

When working with multiple projectors, you may want to use the RS-232 ports to chain the projectors together in a network that you control from either a keypad or a computer/controller (see 2.9, Serial Port Connections). Or you may prefer that each projector stands alone, in which case you will probably use a single IR remote keypad. In either case, you can switch back and forth between broadcasting to all projectors or controlling each projector individually.

Make sure you have assigned a unique projector number to each projector

present — this number will be required in order get the exclusive attention of an individual projector. To assign a projector number:

The exclamation point within the equilateral triangle alerts the user to important operating and maintenance (servicing) instructions in the literature accompanying the projector.

The lightning flash and arrowhead symbol within the equilateral triangle alerts the user to uninsulated "dangerous voltage" within the projector's enclosure that may be of sufficient magnitude to constitute a risk of electric shock.

Operate the projector in an environment which meets the operating range

specifications in Section 5, Specifications. Do not operate the projector close to water, such as near a swimming pool.

Do not place the projector on an unstable cart, stand or table. If the projector is to be ceiling mounted, only use an Electrohome-approved ceiling mount fixture.

A projector and cart combination should be used with care. Sudden stops, excessive force, and uneven surfaces may cause the projector and cart combination to overturn.

The arc lamp operates at a very high temperature and pressure. Failure to allow the lamp to sufficiently cool prior to handling could result in an explosion causing personal injury and/or property damage. After turning the projector off it is important that you wait at least five minutes before unplugging it.

Do not allow anything to rest on the power cord. Locate the projector where the cord cannot be abused by persons walking on it or objects rolling over it.

Operate the projector at the specified voltage. Do not overload power outlets and extension cords as this can result in fire or shock hazards.

The projector is equipped with a three wire plug having a third (grounding) pin. This is a safety feature. If you are unable to insert the plug into the outlet, contact an electrician to have the outlet replaced. Do not defeat the safety purpose of the grounding-type plug.

Slots and openings in the projector provide ventilation. To ensure reliable operation of the projector and to prevent overheating, these openings must never be blocked or covered. The projector should never be placed near or over a radiator or heat register. The projector should not be placed in an enclosure unless proper ventilation is provided.

Do not push objects of any kind into the projector through the ventilation openings. They may touch dangerous voltages or short-out components resulting in a fire or shock hazard. Do not spill liquids of any kind into the projector. Should an accidental spill occur, immediately unplug the projector and have it serviced by a qualified service technician.

If any of the following conditions exist, unplug the projector from the power

outlet and refer service to qualified service personnel.

• The power cord has been damaged.

• The internal cooling fans do not come on when the projector is first turned on.

• Liquid has been spilled into the projector.

• The projector has been exposed to excessive moisture.

• The projector does not operate normally.

• The projector has been dropped or the case has been damaged.

• Projector performance has deteriorated.

Do not attempt to service the projector yourself. All servicing must be performed by a qualified Electrohome service technician. If replacement parts are required, it is important that only Electrohome-approved parts are used. Other parts may result in fire, electric shock or risk of personal injury.

Clean the projector when required. Before cleaning, always unplug the projector from the power outlet.

To avoid the risk of scratching the lens, only clean the lens if absolutely

required. A small amount of dust on the lens will have very little effect on picture quality. If the lens must be cleaned, use a DRY soft cotton cloth. Clean gently in a circular motion.

It is important to never touch the sapphire (glass) surface of the lamp, as the oil

imprint will seriously degrade lamp performance. The wire mesh protector should prevent this. However, should you accidentally touch the surface of the lamp, clean carefully with a lint-free cloth moistened with isopropyl alcohol.

Clean the case with a soft dampened cloth. Use a mild commercial cleaner. Do

not use liquid or aerosol cleaners.

The optional IR Remote Keypad uses four AA size, 1.5V batteries (preferably alkaline). To install new batteries, open the battery compartment at the back side of the keypad by pulling on the raised portion of the cover as shown (Figure 4.1)

Remove the lens cap and reposition the projector closer to or further from the screen as necessary for the screen and new lens type. For example, if using a

2.5:1 lens, throw distance should be roughly equal to 2.5

[

the screen width. For accuracy in a permanent installation, always use the appropriate throw distance from Appendix E. Power up and test. Adjust vertical offset as necessary so that display is rectangular.

NOTE: If you install one of the larger Vista lenses you may need to adjust the lens mount tilt UP slightly to compensate for increased gravitational pull on these heavier lenses. On the front bezel of the projector, remove the very small cap located near the top of the lens (at approximately 11 o’clock). Insert a 9/64” Allen key until it seats on the internal hex screw—you may have to move the horizontal offset for access. Turn the screw slightly to adjust the lens tilt UP as necessary.
