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 bright light may harm your eyes. 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. iii S a f e t y S u m m a r y 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. 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 projector on top of or close to a computer or other heat-producing equipment. Liquid Spills Do not set drinks on top of the projector. Spilled liquids can flow inside and cause damage. NOTE: If you open the projector case, you will void the warranty. 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. iv INTRODUCTION The In Focus LP 420TM is specifically designed for the mobile presenter. It packs SVGA graphics with 16.7 million colors into a small, 6.8 pound package. It generates crisp, clear images using Digital Light ProcessingTM (DLP) technology. The LP 420 is easy to connect, easy to use, and easy to maintain. Image Resolution The SVGA resolution of the 420's projected image is 800x600. Screen resolutions between 800x600 and 1024x768 are compressed to 800x600. The 420 cannot compress screen resolutions above 1024x768. If your computer's screen resolution is higher than 1024x768, reset it to a lower resolution before you connect the 420. Compatibility The projector is compatible with a wide variety of computers and video devices, including: · IBM-compatible computers, including laptops, up to 1024x768 NOTE: 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. resolution. · Apple Macintosh and PowerBook computers up to 1024x768 resolution. · Most standard VCRs, camcorders and laser disc players.

DO NOT use this to connect to the projector. the A/V cable remain unused (Figure 8). 5 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. 10 Powering up the Projector and Adjusting the Image 1 Remove the lens cap. 2 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. 3 Turn on the projector. · The In Focus startup screen displays and the Power LED on NOTE: Always use the power cord that shipped with the projector. top of the projector lights. 4 If you connected a video player, turn it on. · The video image should display on the projection screen. If a computer source is active, press the source button on the keypad (page 15) to display your video image. You can select a default source to determine which source the projector examines first during power-up for active video; see "Default Source" on page 23. · Use the volume buttons to adjust the volume. 5 Turn on your computer. · The computer image should display on the projection screen. (If a video source is active, press the source button to display your computer's image.) · If necessary, make adjustments to the image from the pro- jector's on-screen menus. To open the menus, press the menu button on the keypad, then select the Display or Image menu. For more information about the menus, see page 16. NOTE: With some computers, the order in which you power up the equipment is very important. Most computers should be turned on last, after all other peripherals have been turned on. Refer to your computer's documentation to determine the correct order. 11 S e t t i n g u p t h e P r o j e c t o r Turning Off the Projector If you want to turn off the projector for a short period of time, press the standby button on the keypad. This blanks the screen for fifteen minutes, but keeps the projector running. After 15 minutes, the lamp goes out (the projector keeps running). To exit standby mode, press the standby button again.

To completely power off the projector, press the "O" side of the power switch on the side of the projector. If you want to turn the projector back on immediately, you must allow about a minute for the lamp to cool. The lamp won't light if it's too hot. CAUTION: When you disconnect the projector after you have switched it off, always remove the power cord from the electrical outlet first, then remove it from the projector. 12 USING THE PROJECTOR This section describes how to use and make adjustments to the projector. It also provides a reference to the keypad buttons and the options available from the on-screen menus. Basic Image Adjustment 1 Make sure you have powered up your equipment in the right order (page 11). 2 If the image doesn't display completely, adjust the height of the projector (page 14) or center the image by adjusting its horizontal or vertical position (page 21). Be sure the projector is at a 90 degree angle to the screen. 3 If the image is out of focus, rotate the focus lens (page 13). 4 If the image appears to shimmer or if it has blurry vertical bars after you have adjusted the focus, turn Auto Image (page 20) off and then back on to reset the automatic sync and tracking. If that doesn't clear up the image, turn Auto Image off adjust the sync (page 21) and/or the tracking (page 21) manually. 5 If the colors don't look right, adjust the brightness (page 17). Adjusting the Projector To focus the image, rotate the focus ring (Figure 9) until the image is clear.
