投影仪使用规范-富可视in系列
投影仪使用规范
1、开投影机电源之前，需要确认连接投影机电缆正常连接，同时要
确保视频源已经正常输出。
投影机上的电源指示灯O I亮琥珀色2、正确开机顺序：按投影机或遥控器上的"power"（电源）按钮。
电源指示灯将开始闪烁绿色。
等到闪烁的绿色信号灯停止闪烁时，开机完成。
这过程可能需要一分钟时间，灯泡才能达到完全光度。
3、要关闭时，不能直接切断电源。
这样的操作，是使用投影仪的“大
忌”，因为投影仪在长时间使用的情况下直接关机会严重影响投影仪灯泡的使用寿命,并且容易炸灯泡（炸灯泡不在保修范围内）。
4、正确关机顺序：先按下"power"（电源）按钮，当屏幕出现是否真
的要关机的提示时，再按一下"power"（电源）按钮，随后投影仪控制面板上的绿色信号灯开始闪烁，等到投影仪内部散热风扇完全停止转动、绿色信号灯停止闪烁时，再将投影仪的电源切断。
这过程需要约五分钟，需要最后讲完PPT，提前将投影仪关闭。
5、在每次开、关机操作之间，最好保证有3分钟左右的间隔时间，
目的是为了让投影仪充分散热。
开、关机操作太频繁，容易造成投影仪灯泡炸裂或投影仪内部电器元件被损坏。
6、投影机在持续开机5-6小时的情况下，最好关机让机器休息20-30
分钟，开机时间过长同样容易造成投影仪灯泡炸裂或投影仪内部电器元件被损坏。
