<P =Msonormal style="MARGIN: 0cm 0cm 0pt"><SPAN style="FONT-FAMILY: 仿宋_GB2312"><FONT size=3>  光电管及聚焦透镜的清洗方法是:拔掉连接激光头组件的一组扁平电缆,记住方向,拆开激光头组件。这时能看到护套罩着激光头聚焦透镜,去掉护套后会发现聚焦透镜由四根细铜丝连接到聚焦、寻迹线圈上,光电管组件安装在透镜正下方的小孔中。用细铁丝包上棉花沾少量蒸馏水擦拭(不可用酒精擦拭光电管和聚焦透镜表面),并看看透镜是否水平悬空正对激光管,否则须适当调整。至此,清洗工作完毕。<SPAN lang=EN-US> <o:p></o:p></SPAN></FONT></SPAN></P>
