SAFETY SUMMARY

Please read these instructions carefully before using your LP 420. Failure to comply with them could result in fire, electrical shock, personal injury or damage to equipment.

These graphics are used throughout this manual to draw your attention to important information about the projectors.

NOTE: Additional useful details or tips.

CAUTION: Steps to take to avoid damage to your equipment.

WARNING: Steps to take to avoid personal injury.

These graphics are used on the projector’s labels.

Attention

- Refer to this User’s Guide for important

safety information.

CAUTION-Hot Surfaces

- Avoid touching hot surfaces.

Do not touch until the projector has cooled.

Do Not Look Into The Lens!

Be extremely careful not to look into the projection lens when the projector is turned on. The b right light may harm y o ur eye s. Be especially careful to keep children from looking into the lens.

Power Source

Use only a three-wire grounding type power source. The power source should not exceed 275 volts rms between the supply conductors or between either conductor and the ground.

Power Cord

Use only the power cord that was shipped with the projector. Although other power cords might be similar in appearance, they have not been safety-tested with the projector. Do not use a power cord if it has become damaged or frayed. Contact your In Focus dealer or call In Focus if you need to replace your power cord.

Safety Summary

Grounding

The projector is grounded through the grounding conductor on the power cord. To avoid electric shock, plug the power cord into a properly wired receptacle. Do not defeat the purpose of the grounding-type plug.

Lamp

To avoid overheating and unacceptable image quality, replace the projection lamp with a lamp of the specified type. Refer to page 33 for lamp specifications and to page 25 for instructions on replacing the lamp.

Lamp Compartment

To avoid burns, do not open the lamp module door until the projector is turned off and the lamp has cooled for at least 30 minutes. Follow the instructions in this manual for lamp replacement carefully.

Hot Surfaces

Allow the projector to cool at least 30 minutes before replacing a lamp. When you open the lamp housing, be very careful not to touch the hot surfaces inside.

NO TE: If you open the projector

case, you will void the warranty.

Ventilation and Overheating

Openings in the projector case provide ventilation to protect it from overheating. Keep loose papers and other objects well away from the grills. Do not place the project or on top of or close to a computer or othe r heat-producing eq uipment.

Liquid Spills

Do not set drinks on top of the projector. Spilled liquids can flow inside and cause damage.

Do Not Disassemble

All service must be performed by an authorized In Focus service center. The only user-serviceable part in the projector is the projection lamp, which you can replace by opening the lamp cover on the side of the projector (see page 25). Do not open any other part of the projector. If your projector needs repair, call your local Authorized Service Provider or In Focus Technical Support as described on page 4. Before you call, refer to “Troubleshooting” starting on page 29 to see if you can resolve the problem yourself.

•

IBM-compatible computers, including laptops, up to 1024x768 resolution.

NO TE: The 420 automatically expands 640x480 images to 800x600. You can display these images at 640x480 by turning off the Auto Resize feature. See “Auto Resize” on page 20 for more information.

SETTING UP THE PROJECTOR

Place the projector on a flat surface.

•

The projector must be within 10 feet (3 m) of your power source and within 6 feet (1.8 m) of your computer.

•

If you want to project from behind a translucent screen, set up the projector behind your screen. See “Rear Projection” on page 23 to reverse the image.

Position the projector the desired distance from the screen.

•

The distance from the lens of the projector to the screen determines the size of the projected image. Figure 3 shows three projected image sizes. For more information about image size, see “Projected Image Size” on page 43.

Make sure the projector and your computer are turned off.

NO TE: Many laptop computers do not automatically turn on their external video port when a secondary display device such as a projector is connected. Refer to your computer manual for the command that activates the external video port. Activation commands for some laptop computers are listed in the Appendix of this manual on page 37.

NO TE: If you are connecting a desktop computer and want to view your presentation on your monitor, purchase the optional CableWizard.

NO TE: If you w ant mouse control, purchase the optional CableWizard and remote.

Connecting a Video Player

If your video player uses a round, one-pr on g composite video

connector, you’ll need only the A/V cable that shipped with the projector.

•

If your video player uses a round, four-prong S-video connector, you’ll need an S-video cable in addition to the A/V cable. The S-video cable is sold separately. (See “Accessories” on page 35.)

Plug the A/V cable’s yellow connector into the “video-out”

port on your video player (Figure 7). This port may be labeled “To Monitor.”

•

If you’re using an S-video cable, connect it to the “s-video out” connector on the video player (Figure 8).

Plug the other yellow connector int o the composite connector

on the back of the projector.

•

If you’re using S-video, plug the other end of the cable into the “s-video” connector on the projector (Figure 8).

Connecting the projector to a video player using an S-video cable and the audio connectors on the standard A/V cable

Plug the A/V cable’s white connector into the left “audio out”

port on your video player. Plug the cable’s red connector into the right “audio out” port on the video player (Figure 7 and Figure 8).

CAUTION: Your video player

may also have a “Video Out” port

for a coaxial cable connection.

DO NOT use this to connect to the

projector.

•

If you’re using an S-video cable, the yellow connectors on the A/V cable remain unused (Figure 8).

Plug the A/V cable’s other white and red connectors to the

left and right “audio in” ports on the projector.

The projector is compatible with these major broadcast video standards: NTSC, NTSC 4.43, PAL, PAL-M, PAL-N, and SECAM. It automatically adjusts to optimize its performance for the incoming video. The input signals for SECAM, PAL-M, and PAL-N video are similar to other video signals and cannot be automatically detected, therefore they must be chosen manually. See “Video Standard” on page 22 for details.

Po wering up the Projector and Adjusting the Image

Remove the lens cap.

Plug the power cord into the side of the projector, then plug it

into your electrical outlet. A surge-protected power strip is recommended if power surges are common in your area.

Turn on the projector.
