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 250 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 26 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 bottom of the projector (see page 26). 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 740TM is a multimedia projector that packs SXGA graphics (1280x1024) with 16.7 million colors.
