|
Does not turn on or shut | • Check that the power cord is plugged in and that the power button on the projector cabinet or the remote control is on. See |
down | pages 23 and 24. |
| • Ensure that the lamp cover is installed correctly. See page 60. |
| • Check to see if the projector has overheated or the lamp usage exceeds 2100* hours (up to 3100* hours : Quiet mode). See |
| page 60. If there is insufficient ventilation around the projector or if the room where you’re presenting is particularly warm, |
| move the projector to a cooler location. |
| * |
| • The lamp may fail to light. Wait a full minute and then turn on the power again. |
| • The lamp has reached the end of its usable life. Replace the lamp. |
| • When the lamp is turned off, the projector internal temperature is hot. If the power is turned on before the projector has |
| cooled down, the fan will run a short time before the lamp will turn on. If this happens, wait a couple minutes and turn on the |
| projector. |
|
|
| • Set [Fan mode] to [High altitude] when using the projector at altitudes approximately 5500 feet/1600 meters or higher. Using |
| the projector at altitudes approximately 5500 feet/1600 meters or higher without setting to [High altitude] can cause the |
| projector to overheat and the projector could shut down. Also the projector could not turn on due to the increased temperature |
| of the lamp after power off. If these happen, wait a couple minutes and turn on the projector. |
|
|
| • Select [High] in [Fan mode] if you use the projector at a high altitude or under low atmospheric pressure because |
| |
| low atmospheric pressure without setting to [High] can cause the projector to overheat and the projector could shut down. |
| Furthermore, the projector could not turn on due to the increased temperature of the lamp after power off. If these happen, wait |
| a couple minutes and turn on the projector. |
