There is no guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their lifetime in a shorter period of time than other similar lamps. If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE INDICATOR lights up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down. ( Follow carefully the instructions in the LAMP REPLACEMENT section of this manual. ) Continuous use of the lamp with the LAMP REPLACE INDICATOR lighted may increase the risk of lamp explosion. A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its lifetime draws to an end. Risk of explosion may differ according to the environment or conditions in which the projector and lamp are being used. IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE TAKEN. If a lamp explodes, disconnect the projector’s AC plug from the AC outlet immediately. Contact an authorized service station for a checkup of the unit and replacement of the lamp. Additionally, check carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out from the cooling air circulation holes. Any broken shards found should be cleaned up carefully. No one should check the inside of the projector except those who are authorized trained technicians and who are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those who are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken glass. Move the pointer to Lamp counter reset and then press SELECT button. The message “Lamp replace counter reset?” is displayed. APPENDIX OPERATING WIRELESS MOUSE The Wireless Remote Control Unit is not only able to operate this projector but is also usable as a Wireless Mouse for most Personal Computers. The POINT button and two CLICK buttons are used for wireless mouse operation. This Wireless Mouse function is available only when PC mouse pointer is displayed on a projected screen. When ONSCREEN MENU or any message / dialog box is displayed on the screen instead of PC mouse pointer, the POINT and CLICK buttons control the projector, rather than the computer. INSTALLATION To use the Wireless Remote Control Unit as Wireless Mouse, a mouse driver must be already installed on your computer. No mouse driver is supplied with this projector: instead, the Wireless Remote Control Unit becomes the pointing device for your computer's existing mouse driver. Make sure that the mouse driver is properly installed in your computer, and that the appropriate port (PS/2, DB9, ADB, or USB port) is activated. Note that only a PS/2 mouse cable is supplied with the projector: for other mouse cables, contact your dealer. 1 1 With the projector and computer both OFF, connect the mouse port (or USB port) of your computer to Control Port (or USB connector) of this projector with the appropriate cable. (Refer to page 11, 12 for connection.) 2 2 Turn the projector ON first, and then turn ON your computer. When the computer is switched on first, Wireless Mouse may not work properly.
