Removing the filter unit while the projector is running could result in burns or electric shocks from touching internal parts. NOTE: • The wireless LAN unit has a front and a back and must be mounted in the wireless LAN port in a specific direction. The port is designed so that the unit cannot be mounted in the opposite direction, but trying to push it in by force could damage the wireless LAN unit port. • To prevent damage due to static electricity, touch a nearby metal object (a door knob, aluminum sash, etc.) before touching the wireless LAN unit to eliminate the static electricity from your body. • Disconnect the power cord when mounting and removing the wireless LAN unit. Mounting and removing the wireless LAN unit while the projector’s power is on could damage the wireless LAN unit or result in malfunction on the projector. If the projector should malfunction, turn off the projector’s power, unplug the power cord, then plug the power cord back in. • Do not attach USB devices other the wireless LAN unit to the USB (LAN) port inside the main body.

171 7. Maintenance This section describes the simple maintenance procedures you should follow to clean the filters, the lens, the cabinet, and to replace the lamp and the filters. ❶ Cleaning the Filters The air-filter sponge keeps dust and dirt from getting inside the projector and should be frequently cleaned. If the filter is dirty or clogged, your projector may overheat. WARNING • Please do not use a spray containing flammable gas to remove dust attached to the filters, etc. Doing so may result in fires. NOTE: The message for filter cleaning will be displayed for one minute after the projector is turned on or off. When the message is displayed, clean the filters. The time to clean the filters is set to [OFF] at time of shipment. (→ page 108) To cancel the message, press any button on the projector cabinet or the remote control. The two-layer filter on the projector improves cooling and dust-proof capabilities compared with the conventional models. The outsides (the intake vent side) of the first and second layer filters remove dust. To clean the filter, detach the filter unit and the filter cover. CAUTION • Before cleaning the filters, turn off the projector, disconnect the power cord and then allow the cabinet to cool. Failure to do so can result in electric shock or burn injuries. 1. Press down on the buttons on the left and right and then pull the filter cover towards you to open it. The cover will open about 90 degrees before it stops.

WARNING • Please do not use a spray containing flammable gas to remove dust attached to the lens, etc. Doing so may result in fires. ❸ Cleaning the Cabinet Turn off the projector, and unplug the projector before cleaning. • Use a dry soft cloth to wipe dust off the cabinet. If heavily soiled, use a mild detergent. • Never use strong detergents or solvents such as alcohol or thinner. • When cleaning the ventilation slits or the speaker using a vacuum cleane\ r, do not force the brush of the vacuum cleaner into the slits of the cabinet. Vacuum the dust off the ventilation slits. • Clogged ventilation slits may cause a rise in the internal temperature of the projector, resulting in malfunction. • Do not scratch or hit the cabinet with your fingers or any hard objects • Contact your dealer for cleaning the inside of the projector. NOTE: Do not apply volatile agent such as insecticide on the cabinet, the lens, or the screen. Do not leave a rubber or vinyl product in prolonged contact with it. Otherwise the surface finish will be deteriorated or the coating may be stripped off. 7. Maintenance
175 ❹ Replacing the Lamp and the Filters When the lamp reaches the end of its life, the LAMP indicator in the cabinet will blink red and the message “THE LAMP HAS REACHED THE END OF ITS USABLE LIFE. PLEASE REPLACE THE LAMP AND FILTER. USE THE SPECIFIED LAMP FOR SAFETY AND PERFORMANCE.” will appear (*). Even though the lamp may still be working, replace the lamp to maintain the optimal projector performance. After replacing the lamp, be sure to clear the lamp hour meter. (→ page 129) CAUTION • DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off and then disconnect the power cord. Allow at least one hour for the lamp to cool before handling. • Use the specified lamp for safety and performance. • DO NOT REMOVE ANY SCREWS except one lamp cover screw and two lamp housing screws. You could receive an electric shock. • Do not break the glass on the lamp housing. Keep finger prints off the glass surface on the lamp housing. Leaving finger prints on the glass surface might cause an un- wanted shadow and poor picture quality. • The projector will turn off and go into standby mode when you continue to use the projector for another 100 hours after the lamp has reached the end of its life. If this happens, be sure to replace the lamp. If you continue to use the lamp after the lamp reaches the end of its life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury. If this happens, contact your Ricoh dealer for lamp replacement. *NOTE: This message will be displayed under the following conditions: • for one minute after the projector has been powered on • when the (POWER) button on the projector cabinet or the STANDBY button on the remote control is pressed To turn off the message, press any button on the projector cabinet or the remote control.
