Timing of replacing the lamp When the Lamp indicator lights up red or a message appears suggesting it is time to replace the lamp, please install a new lamp or consult your dealer. An old lamp may cause a malfunction in the projector and in some instances the lamp may explode. Do not attempt to replace the lamp yourself. Contact the qualified service personnel for replacement. The Lamp indicator light and Temperature warning light will light up if the lamp becomes too hot. See "Indicators" on page 66 for details. The following lamp warning displays will remind you to change the lamp. The warning messages below are for reference only. Please follow the actual on-screen instructions to prepare and replace the lamp. Status Message Install a new lamp for optimal performance. If the projector is normally run with Economic selected ("Setting Lamp mode" on page 59), you may continue to operate the projector until the next lamp warning appears. A new lamp should be fitted to avoid the inconvenience when the projector runs out of lamp time. It is strongly recommended that you replace the lamp at this stage. The lamp is a consumable item. The lamp brightness diminishes with use. This is normal lamp behavior. You can replace the lamp whenever you notice that the brightness level has significantly diminished. The lamp MUST be replaced before the projector will operate normally. "XXXX" shown in the above messages are numbers that vary depending on different models. Maintenance 61
