USER GUIDELCD PROJECTOR31 10 MAINTENANCE From time to time, the housing and lens may be cleaned with a damped, non abrasive cloth, possibly using a mild detergent to remove spots. Always be careful with the lens surface and use the lens cap for added protection when the projector is not in use. 10.1 LAMP REPLACEMENT The lamps are replaced by opening the rear door of the housing.Always replace the defective lamp as soon as the projector has cooled down after use. Make sure to use the correct lamp, see Technical Data section.To avoid burns, do not open the rear door to replace a defective lamp until the unit has cooled down after operation. The interior of the projector is heated during use. When the housing has cooled down, open the rear door. The defective lamp is positioned vertically either to the right or to the the left. See figure. Remove the old lamp and replace with a new one.Never touch the glass bulb of a new lamp. This will shorten the lifetime of the lamp. Keep the plastic bag on the lamp until fully inserted, then remove it.
USER GUIDELCD PROJECTOR32 10.2 FUSE REPLACEMENT The mains fuse is located at the mains input, as an integral part of the connector and switch assembly. See the figure.A defective fuse may indicate a permanent electrical failure. If a new fuse breaks immediately, please return the unit for repair. Do not attempt to open the unit, as this will void any warranty and possibly cause injury. Release the fuse holder and replace the broken fuse with a new one. Make sure to use a fuse of correct rating, see Technical Data section. There is room for a spare fuse in the holder.11 SERVICEThis product contains no user serviceable parts. Attempts to modify mechanics or electronics inside the housing will violate any warranties, and may be hazardous. If for any reason the product fails to work properly, first check the previous chapter on hints and tips. If things still do not work, please contact your dealer for technical support. Prepare a list of the symptoms you observe to make the diagnosing easier for your dealer. Remember to include all cables when returning the goods.

USER GUIDELCD PROJECTOR38 14 FCC STATEMENT This equipment has been certified to comply with the limits for a Class A computing device, pursuant to Subpart J of Part 15 of FCC rules. Only peripherals (computer input/output devices, terminals, printers, etc.) certified to comply with the Class A limits may be attached to a computer that complies with Class A limits. When connecting to a peripheral device, a shielded input/output cable is required to ensure compliance with FCC rules. The shielded cable that must be used is supplied with the equipment. Operation with non-certified peripherals or non-shielded cables is likely to result in interference to radio and TV reception. 14.1.1 INSTRUCTIONS TO USER This equipment generates and uses radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause interference to radio and television reception. It has been tested and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart J of Part 15 of the FCC rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures : Reorient the receiving antenna. Relocate the computer with respect to the receiver. Plug the equipment to a different outlet so that equipment and receiver are on different branch circuits. Fasten cables using mounting screws to ensure adequate EMI control. You may require the following booklet from the Federal Communications Commission (FCC) : How to identify and resolve radio and TV interference problems, available from the U.S. Government Printing Office, Washington, DC 20402, Stock No. 004-000-00345-4.
